Are there any processes that use sound card? Try to run lsof /dev/snd/*.

I'm suspecting of the snd-pcm-oss module (which isn't even used anymore) so I removed it and I'm testing if it's fine now (I'll reply here if it's solved ;).
Thanks.

What's strange is that when I use Skype, the other software complain. MPlayer for example:
[AO_ALSA] alsa-lib: pcm_hw.c:1590:(snd_pcm_hw_open) open '/dev/snd/pcmC2D0p' failed (-16): Device or resource busy
[AO_ALSA] alsa-lib: pcm_dmix.c:1029:(snd_pcm_dmix_open) unable to open slave
[AO_ALSA] Playback open error: Device or resource busy
Failed to initialize audio driver 'alsa'
Could not open/initialize audio device -> no sound.
So it seems Skype is blocking the sound card, even if I'm using dmix. Strange, no?

I would say, something is locking sound card exclusively. That shouldn't happen if all applications output sound through dmix. But happens somehow.

So, to reiterate. Bug appears when you are using Skype with apulse, but doesn't appear when you are playing sound with mplayer?
from apulse.
DanielFragaBR
commented on August 25, 2024
Yes, this is correct. I can play a video on Youtube through Firefox and Flash and at the same time play sounds with MPlayer.
Only when I use Skype with Apulse on a conversation the sound card is locked and no other application can use the sound card.

Have you tried to use default device with apulse? In other words, without using APULSE_PLAYBACK_DEVICE and/or APULSE_CAPTURE_DEVICE.
From what I know about .asoundrc file, that configuration should be enough.

Yes, I tried, but it returns these errors:
ALSA lib confmisc.c:674:(snd_determine_driver) could not open control for card 0
ALSA lib conf.c:3328:(snd_config_hooks_call) function snd_config_hook_load_for_all_cards returned error: Invalid argument

Any hints?

Unknown PCM dsnoop:0,0
From my tests, numbers are working for dmix, but doesn't work for dsnoop.
Could you try the following .asoundrc?
pcm.dsnooped {
type dsnoop
ipc_key 1027
slave.pcm "hw:0,0"
}
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "dmix:2,0"
}
capture.pcm {
type plug
slave.pcm "dsnooped"
}
}

Ok, I tried the .asoundrc you provided and I got new error messages:
ALSA lib timer_hw.c:342:(_snd_timer_hw_open) Unexpected field hint

Googling gives a hint — check if you have /dev/snd/timer file.

commented on August 25, 2024
It seems ok:
ls /dev/snd/timer -l

commented on August 25, 2024
Well, I'm out of ideas. If only to change "hw:0,0" to "hw:0". Maybe it doesn't like subdevice 0.
from apulse.
DanielFragaBR
commented on August 25, 2024
I tried, but it doesn't seem to make any difference. Anyway, I'll keep trying (or using with APULSE_PLAYBACK_DEVICE=plughw:2,0 APULSE_CAPTURE_DEVICE=plughw:0,0 since it at least works temporarily).
Thanks!

plughw
Just for your information, plughw devices are not using dmix or dsnoop. So if one application uses plughw:0,0, no other app will have access to the audiocard. The difference between hw and plughw is that plughw have automatic sample rate conversion.

DanielFragaBR
commented on August 25, 2024
Hmm ok, so that's it. So is there a way to use APULSE_PLAYBACK_DEVICE and APULSE_CAPTURE_DEVICE to force it to use dmix/dsnoop?
from apulse.
i-rinat
commented on August 25, 2024
I would try
APULSE_PLAYBACK_DEVICE=dmix:2,0 APULSE_CAPTURE_DEVICE=plug:dsnoop apulse skype

Good news. The solution was simple:
There was some issue between 32 bit ALSA libraries and the 'hint" sections, so I just removed it from /usr/share/alsa/alsa.conf:
"I just fixed sound in csgo by editing /usr/share/alsa/alsa.conf and commenting out the timer hint sections at lines 584 and 630-633."
Now it's perfect! I'm closing this,since it isn't a bug of apulse.

Glad to hear it!
One of the cryptic issues that's actually fixed. That's rare, unfortunately.
