Well, it seems that I'm going to have to answer my own self ... :)
The following is what I've been able to find using additional tracing
info. Also there's a fix for usbaudio.c.
Basically, it's as I said before: the usbaudio driver uses URBs
without even checking if they're in use or not. Surprisi
I'm running RedHat 7.3 (RH kernel 2.4.20-20.7, gcc 2.96-113), and have a
generic Aureal Vortex 1 card (au8820 chipset). Compiling and installing
the 1.0.0pre1 ALSA driver works fine, but if I do a 'modprobe
snd-au8820', the computer locks up instantly (can't even ssh in from
another computer).

I am currently working on a 'no-compilation, no-installation,
no-programming' user manual for Alsa-Jack-Ladspa.
I wanted to bring some friends of mine to Linux. They use Windows based

capababilities of Alsa-Jack-Ladspa(-Lad

Looks like so
Hm, sounds like the very definition of a hardware issue to me. ;) When I
said "hardware issue" I wasn't refering to a bug in the hardware or
hardware drivers... more of a "that's how it works and we're stuck with
it". :)
One of our other engineers has taken that exact approach. It just seems
Hi,
This is not a hardware issue. The problem is that the DAC of your card
gets stopped in some other level than 0V and when you restart playback
the voltage differential causes the pop (because the output of the
digital to analog converter is AC-coupled). To perform a clean stop and
start make su
Mark,
I don't know if it's the same effect or not. We're working on an
"embedded" Linux device. It has a full Linux kernel and basically is a
hand-built distribution of stock Linux stuff, but is very stripped down
and some of our apps are custom. As we're not using OSS in any way

You're the first person I can remember to report something very similar
to what I'm dealing with every day. I get a huge loud cracking noise at the
start of any audio operation that is not vanilla Alsa - i.e. - anything
accessing OSS I think. In my case I think it's hardware based, but I'
Was the patching described by Eric Hathaway's post done for the new version,
or was it decided it wasn't really necessary? See: [Alsa-devel] aureal

I would also like to suggest that the INSTALL file and read me files
All,
We're having a problem with some of our audio applications. When a song
starts playing we will often hear a loud pop out of the speakers before
it plays audio. It seems dependent upon where we stoped and the specfic
content of the last song, if we hit our "stop control" and abort in the
I was hoping that the recent flurry of fixes in the ac97 modules would
fix my problem [Oops on my Sony Viao Z505S laptop with snd-nm256].
They haven't, but at least I seem not to freeze. Here's the latest
ksymoops output. [I just finished running CVS and rebuilding in all
alsa-* directories].

The PnP compatibility stuff doesn't seem to work at all - compiling

I've been trying to fix some problems I'm getting with the USB audio
driver.
Basically, I get these types of messages over and over accompanied
by some audio glitches:

oh yeah, you're right, ALC655 is not completely compatible with

If I use surround51 directly I cannot get sound out of the other

Hi all,
as you might have already seen on the web news page, we released
1.0.0pre1 tarball. This is intended for the wide tests before the
official 1.0.0 release. We planned to release 1.0.0 (hopefully) in
this month, so please everyone test this version and give bug reports
now.

Thanks Takashi.
However I seem to have got Center/LFE switched with Surround.
I.e. if I play xine & mplayer (L, R, RearL, RearR, Center, LFE)
through surround51 I get Center/LFE switched with Rear speakers.
