Before this patch, if any of the paths in a path set do not
support HW volume then the HW volume is disabled for the whole
set. In some cases this is a bit drastic measure. For instance,
if all but one of the paths support HW volume and dB there no
problem to pretend that we have HW volume for the whole set. The
path without any mixers to control will just always return 0 dB
and the rest is handled by SW volume. This patch adds a flag to
the mapping section of profile set file to enables this behavior.


David, this sounds similar to your USB Headset issue from a couple days
ago... or am I just reading too much into the description?


Sort of - it just feels like neither of us has tried to do the right 
thing so far - I added a workaround/quirk for a few devices, and this 
patch adds a setting to turn something on and off.


I'd like it to just work.

Or put in another way - what's the recommended default setting of this 
new parameter, and why?

Re: [pulseaudio-discuss] Conexant CX20585 recording does not work

Hi!

 OK, so Gabriel, this sounds like one to take over to alsa-devel mailing
 list (I'd avoid their bug tracker - it's a black hole!). You should
 attach the alsa-info output to that mail.

I went over to alsa-devel, and I have found a solution that makes arecord
work, however, recording continues to block in pulseaudio. Here's what I
did:

1. I added options snd-hda-intel model=ideapad to /etc/modprobe.d
2. I verified that ideapad was set in
/sys/modules/snd_hda_intel/params/model:
ideapad,(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null),(null)
3. I booted to runlevel 3 to avoid pulseaudio from starting, and logged in
as my mom.
4. I recorded something using arecord  tmp.wav
5. I played it back. I heard what I had recorded.
6. I rebooted to runlevel 5.
7. I logged in using GNOME, and I looked at the sound preferences menu, in
input. I found that the level indicator wasn't moving at all.
8. I tried a skype test call. It looked like it was recording my voice for
10 seconds, but when it was to play it back, it played back a NULL
sequence - not 10 seconds of static, but a sequence that was 0 seconds in
length.

Please let me know if there's anything else I can do, especially since
skype no longer supports ALSA!

TIA,



Gabriel
