Yea, I'm still trying to find the energy to begin to write a parser for
the codec commands, but this will surely take quite a lot of time.

Luckily on the ALC892 datasheets are available online, so even if it is
a vendor defined command (assuming they exists, but I think that's the
case) from Realtek, we should be able to identify it.

The problem is that I can't find the strength to read ca 120 pages
(between vendor and HDA spec) of commands right now and extrapolate a
script to parse them :P

Maybe later this year I'll be giving that a shot; but not right now. For
now I'm adapting to use an external audio card; at least for voice chat,
it's good enough for me.

Yep, they are coming from my ALC892. If you want to try to create a
script to parse them, be my guest :)

The only issue on Windows is that after the dump, the audio stack from
Windows wasn’t responding; however that should not be an issue, if it’s
simply a state change from the driver at boot up.

This seems more in line with the problems in this thread, to me.

[rodomar705]

After purging VFIO finally the PCI audio cards works again even after
reenabling it. However now from the front panel only the right channel
works from the front jack, from the back both works correctly.

I don't really understand anything now; nor what the problem is. I'll
try to replay some interesting commands from the decoded win dump,
hoping for the best; however with all this random problems popping up,
I'll really doubt that I will be able to fix anything.

[Touch-packages] [Bug 1801540]

[rodomar705]

Well, another update that probably will be the last one from me, since
I'm beginning to really hate ALSA.

Decided today to try to test some parameters; I had left the audio card
loaded with VFIO module since the command dump.

Today I've decided to retry to use it, so I've removed the VFIO stubs
from modprobe, rebooted and... no PCI audio card.

Disabled IOMMU to force load the modules (something like this was
already seen by me; even when VFIO wasn't asked to bind it, it would
bind it anyway), no PCI audio card.

lsmod says that the module is loaded on the audio card, however no audio
from any PCI devices, even the audio from the GPU.

I'll attach alsa-info.

Just for reference on your list, when the module was working, I had
output working fine, but input crackling.

Tried everything, including downgrade to a previous kernel, same
behavior. The only thing I get in dmesg now is:

[3.146686] hdaudio hdaudioC0D0: Unable to bind the codec
[3.150739] hdaudio hdaudioC1D0: Unable to bind the codec

Really useful.

Here it is working (5.2.2), but it's worse than before. I will try to
play with parameters now.

Thanks for the base patch, Tiwai. I'll see if with some parameters above
something will change.

However, right now the left channel from my front headphone jack is
still not working.

Found a combination of parameters that seems to fix the issue with arecord, at 
least for 30 seconds, regardless of the sample rate (eg. 44100, 48000 or 
192000, all now are clear recordings) is:
pasuspender -- arecord -D hw:1,0 -f S32_LE -r44100 -d 10 -N -c 2 /tmp/test.wav

The key parameters required are S32_LE as a format and the non blocking
mode -N, otherwise the issue is still present.

I hope that this will help to track down the issue. If other people here
want to try it out to see if this fix their audio problems, that would
be useful as well.

I feel dumb, I had some options inside modprobe that was fixing the
issue with -N apparently. After wiping it out and setting the above
parameter to 64,64, the issue is present regardless of the -N parameter.
I'll try to change it until I'll get the same behavior as before, or
play again with parameters until I can fix it properly?

I can't believe it, it works now with position_fix = 3! I don't know if
this was caused by the additional patch to the kernel, I'll probably try
to remove it to see if it is still working with 3, but I had already
tried all position fix and a heap of other stuff.

The audio now is perfect, even with pulseaudio :)

This is the result that you have requested anyway:

0: Same problem, no other issues
1: Same problem, no other issues
2: Unable to acquire stream, arecord signal overrun!!! (at least 377,780 ms 
long) and no audio is acquired
3: No clicking in the acquired stream!
4: Same problem, no other issues

I have the suspect that it doesn't, since it mentions a null pointer

Regardless, it works even without any patch with position_fix = 3 on the
latest stable kernel, 5.2.5. I had already tried that but now it
actually works.

In the hope that this will help,

Marco.

Latest addition, tsched=0 is still required to have decent audio
acquisition, otherwise the audio is stretched in time. A lot. Otherwise,
after setting that, the audio is perfect now.

This works, and yes, reported sizes makes sense.

I don't really get why an AMD/AsMedia chipset is acting as a VIA one,
but it does look like that that's the case.

Another thing, 1022:1457 is not used only on X370, but also on my B450,
and probably on a lot of other board, like B350 and such. Just a remark
for the comment mentioning only X370 over the PCI device :)

Thanks again,

Sorry, just noticed now, the input is not delayed, the signal on the
screen is in sync with my voice, it's only the output that is retarded
by 4 seconds.

Trying now the DCAPS and then the patch supplied.

Thanks again,

Same behavior as without, with tsched is perfect, without the stream

With tsched=0, everything is perfect. When tsched=0 is removed, the
audio output is not crackling again, however ALL audio is retarded when
the acquisition starts, to me it feels around 4/5 seconds. I had a
player playing music in background and the whole stream jump back for
that time; if i try to seek in another position the audio will seek only
after the same 4/5 seconds. If I stop capturing audio, the playback sync
back again and the playback is working correctly again.

Very weird.

The only step is to not use tsched and try to use a software that use
webrtc as a audio backend, like Discord.

As soon as you test your mic, the audio in playback get shifted back in
time, around 5 seconds.

Thanks both for your time,

Marco.

6 works only with the define enabled, remove the double slashes in front
of #define, then it will work.

Still, this works only with tsched=0 (which to me is good enough,
honestly), but if we can fix even the last issue, that would be perfect.

Whoops, my mistake. Here is the correct trace from hda_controller, same

No, this is with tsched removed from the parameter, so it should be one.
I’m forcing tsched to zero to not have the issue in PA, otherwise the
issue is not present.

If you like, I can post the same trace with tsched=0, if that will help
you narrow down the issue.

I’ll try the patch shortly,

Thanks again for your time,

Marco.

Not for me, on discord the audio is perfect. I still don't get where the

Number 4 works perfectly with tsched=0, but not without, stutters again
(delayed and crackled, probably from playback this time since you
mentioned it). I'll test patch v5 and report back.

Tested the posted patch from you, same issue. Tried to enable all DCAPS
flags (except SNOOP_MASK, SNOOP_ON, because I had used as a base the
patch in attachment 283955 that had already enabled SNOOP_TYPE(ATI); and
I915_COMPONENT (since I do not have an integrated Intel iGPU)) on the
codec specified inside line 20-47 in hda_controller.h, same issue
persists. I don't really know where to proceed. The only change is in
the noise frequency in time, it's more frequent or less, but the issue
is still there.

Compiling a *4 in the parameters, I'll report back shortly.

Yes, the only clean audio stream from PA and arecord was with the define
enabled in the source code.

If it doesen't change, i'll post a trace from the codec.

Yea, same here on B450/ALC892 with tsched enabled (which AFAIK the batch
flag is the same of disabling tsched on the kernel side of things).
Other chipsets instead seems to behave differently (if it is the front
end and not the backend, the Realtek codec).

Very weird.

Forgot to test with aplay without PA with the define disabled, however
the acquired audio with PulseAudio was bad, like "low quality" (and the
output was delayed as before). Using arecord (but not with PA disabled)
I was hearing again a little of crackling. With the define the audio was
perfect again with arecord (however only with PA disabled, I've tried to
use aplay in another terminal while using arecord, however the audio is
played back only when PA resumes; I'm not sure if this is something to
be expected), same thing with PA; however the output was delayed again
(when acquiring from PA). I've tested both S16 and S32 with the define
and pulseaudio disabled, no problem heard.

Neither did nothing, however the audio playback has no problem staying
in sync if I use directly arecord, even without pausing pulseaudio.

So, it is a pulseaudio bug, if with arecord everything works correctly?

Thanks a lot again,

That is unfortunately correct, in Steam Voice Chat the audio is still
stuttering like crazy :S

The stutters remains only for one minute after activating the webrtc
stream on Steam, afterwards the audio clears up and, besides a long
delay of around 1/2 of a second, the audio is clear.

[Touch-packages] [Bug 1801540]

[rodomar705]

I confirm that both version of the second patch work. On playback I had
only some minor issues when the stream was starting, but after enabling
the playback patch, they disappeared too.

Without tsched=0 and without the playback patch, acquisition work
perfectly fine, but not the output, is delayed in time again.

Forgot to test it without tsched and playback and data from fifo
directly and not from VIA register, but I can recompile it if it is
needed.

I think that both patches are needed, even if my playback issue wasn't
that problematic.

Testing n.4 shortly.

Thanks a ton for your work.

[Touch-packages] [Bug 1801540]

[rodomar705]

Following my previous post, disabling the batch flag on both streams
(patch 3 from comment 269), Steam is perfect, Discord is lagged again
while acquiring.

With the second patch from the comment 269, same identical problem
without the patch (Discord perfect, Steam crackling for the first minute
+ audio slightly delayed). However when changing volume there was a
little bit of distortion on the output audio (extremely small, but still
audible, especially on high volumes), but it seems that using the
workaround only on acquisition seems to have removed that small issue.
If someone here had the same problem when changing volume, please try
patch n.2 and report back.

It seems that we can't have both working together simultaneously on my
end. The default workaround is still the best option on my system, for
now.

With the standard flags, Discord is perfect, Steam has stutters for the
first minute and a bit of delay (500 ms).

With the batch flag only on the capture stream, Steam is perfect,
Discord has delayed audio.

With the batch flag only on the playback stream, same thing with both of
them (first case).

The second patch cited in my previous post is necessary now (under
5.3.5, not sure about the previous kernel versions); besides the small
crackles when changing volumes, the acquisition from the microphone
under load (compilation, for example) sometimes becomes extremely low
quality (like if the sample rate is changing randomly and often the
audio is clipping). Applying the patch only on the capture stream
completely fix the issue, no crackles when changing volume and no issue
when acquiring audio with Discord under load.

Steam still shows random audio stutters while acquiring for a minute and
a bit of delay, so that is still unchanged, unfortunately.

[Touch-packages] [Bug 1801540]

[rodomar705]

Updates on this long endeavor as of today: I choose to give another try
for switching from PulseAudio to the PipeWire sound server.

The problems are completely gone. No audio clicking anywhere on the system. 
I have tried one month ago, but on reboot I was not having any audio coming out 
from the system. Now everything worked on install right from the get go. Tried 
also the mic under Steam, which always had audio clicking issue while acquiring 
and audio stalling (don't remember under what condition); acquisition is now 
perfect. Tried to dual test recording from Steam Voice and Discord while 
playing audio, no delay, no crackling, no issue. All streams are working 
simultaneously. I still have not long tested this, by the way, but on a first 
impression, yes, it fixed a lot of issues for me.

The only minor configuration issue was to switch the microphone
detection method in the PipeWire configuration file, otherwise no
microphone were detected. After that, everything work as it should, for
now.

The issue on my end was definitely PulseAudio. If you still have
problems, try PipeWire if you can or if fits your needs. This definitely
solved my problems, maybe it will help yours too.

Marco.

I have tested this (if i have done it correctly, taken from
https://trac.ffmpeg.org/wiki/Capture/Desktop for pulse acquisition,
using PipeWire), and besides a small audio missing at the start of the
recording of about one second and at the end of it (but that was maybe
caused to the ctrl-c to ffmpeg, I'm not sure about that), it looks
pretty much synchronized to me, using a microphone next to my mouse and
selecting text on the screen I can't really see any delay on it (on the
current implemented workaround, Kernel 5.11)

Mind you, I'm on a 0x1487 and not on a 0x15e3 host side controller (not
an "AMD Raven"), so maybe the behavior of the two controllers are
different from each other (or PipeWire is not causing the issue here).

[rodomar705]

After some gaming and streaming, I can confirm that I haven't heard
anymore pops or clicks, and a lot of performance issues completely
disappeared after applying this firmware, like microstutters in the
system under load and such. Kinda makes sense, since PciEx is basically
the main bus where everything is connected on a modern PC; I guess
better late than never.

I'll keep monitored the situation, but I think that at least for me
after this firmware update the issue has been finally fixed.

FWIW, on my system this improves the recording start, removing
completely audio clicks at the start of recording (no audio stalls in
reproduction, even with multiple streams on acquisition while playing
audio), so for my use case it's fine, but someone with PulseAudio should
test this and see if it causes regressions.

[Touch-packages] [Bug 1801540]

[rodomar705]

Update after the latest firmware update for the platform, called AMD
AGESA V2 PI 1.2.0.3 Patch A, released yesterday for my platform,
finally. This includes the USB patch for the drop in the USB
communication under load for too much recovery errors hitting the Pci-Ex
subsystem on the chipset, apparently, that was only present when using
Pci-Ex 4 (B5xx and X5xx, not on b4xx, in theory).

However, the USB issues was still present even on older platform,
apparently. Just not as grave as the 500 series.

The audio clicking is completely gone and the machine is finally much
more responsive; I've yet have to test the system under high loads, but
even on the desktop the audio clicking was audible sometimes, when event
from application fires; after the firmware update, this is completely
disappeared. The audio now is perfect, at least in output. I'll update
here as soon as I can test the recording now.

I didn't think it would change much. But, for me at least, it did.
