@0smile, thanks for reporting the issue. I believe this could be same issue as #455, thanks!

I receive this same error in the terminal when trying to run a rust-lang program with dependencies on libsdl2-dev and libasound2-dev.

same problem with rust and wsl2

[jonaskuske]

Had the same problem with sound playback in Epiphany / GNOME Web, but managed to fix it:

1. Create ~/.asoundrc so ALSA uses WSLg's PulseAudio server as default "sound card":

pcm.default pulse
ctl.default pulse

2. Change the PULSE_SERVER env variable to include the unix: scheme:

export PULSE_SERVER=unix:$(sed 's/unix://g' <<< "$PULSE_SERVER")

And now it should work, at least it did for me :)

@jonaskuske Hi, I have encountered a same issue and I could not resolve it with your way. Using Ubuntu 22.04. I'd be appreciated if you could give me some idea.

I prepended unix: to PULSE_SERVER environment:

$ export | grep PULSE_SERVER
PULSE_SERVER unix:/mnt/wslg/PulseServer

Without ~/.asoundrc:

$ cat ~/.asoundrc
# pcm.default pulse
# ctl.default pulse

$ run_my_program_that_acceses_alsa
ALSA lib confmisc.c:855:(parse_card) cannot find card '0'
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_card_inum returned error: No such file or directory
ALSA lib confmisc.c:422:(snd_func_concat) error evaluating strings
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory
ALSA lib confmisc.c:1334:(snd_func_refer) error evaluating name
ALSA lib conf.c:5178:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory
ALSA lib conf.c:5701:(snd_config_expand) Evaluate error: No such file or directory
ALSA lib pcm.c:2664:(snd_pcm_open_noupdate) Unknown PCM default

After modifying ~/.asoundrc:

$ cat ~/.asoundrc
pcm.default pulse
ctl.default pulse

$ run_my_program_that_acceses_alsa

ALSA lib pcm.c:2664:(snd_pcm_open_noupdate) Unknown PCM pulse

Could it be due to a bug of WSLg, a misconfiguration, or a bug in my program? Do you have any idea what does the error mean, why does the program does not respect $PULSE_SERVER and how could I make it recognize?
At least, I have succeeded in playing sound with ffplay in WSL2.

I found a resolution, which I described in #864 . Actually, I didn't need to modify $PULSE_SERVER. Instead, I needed to install an additional PulseAudio plugin.
