You can add unstable to your sources.list and run # apt update && apt install -t unstable libasound2-plugins HTH Elimar -- On the keyboard of life you have always to keep a finger at the escape key;-) signature.asc Description: PGP signature

Hi Elimar, Sorry for the radio silence. I thought I responded in a previous email, but I guess it never went through? I believe the issue goes deeper than simply setting soundcard priority. I’m experiencing it on two different machines, and I’m trying (and failing) to play sound out of the default device. Desktop: $ cat /proc/asound/cards 0 [HDMI ]: HDA-Intel - HDA Intel HDMI HDA Intel HDMI at 0xf7e14000 irq 50 1 [PCH]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xf7e1 irq 48 2 [U0x46d0x81b]: USB-Audio - USB Device 0x46d:0x81b USB Device 0x46d:0x81b at usb-:00:14.0-1, high speed Laptop: $ cat /proc/asound/cards 0 [PCH]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xe124 irq 127 Both the .asoundrc you suggested and the one given by Pedro Silva solve the problem for me, but it would be nice not to need an .asoundrc to play sound out of the default (or only) sound device. Given that this is happening on a machine with only one sound card device, and that it was working in 1.1.6-1, is there any chance we could have this issue reopened? (FWIW, I’m working against libasound2-plugins 1.1.7-2; don’t know how to upgrade to 1.1.7-3, since I’m on testing and not unstable. Happy to help with any additional debugging.) —Ryan On 2018 Nov 06, Elimar Riesebieter wrote: > * Ryan Lue [2018-11-06 18:51 +0800]: > > > Package: libasound2 > > Version: 1.1.7-1 > > Severity: important > > > > Dear Maintainer, > > > > Please forgive my lack of familiarity with ALSA. > > > > I use sox in a script to play an mp3 via STDIN, using the > > AUDIODRIVER=alsa environment variable.

Hi Elimar,
I found a working ~/.asoundrc :
$ cat .asoundrc
ctl.dmixer {
type pulse
}
pcm.pulse {
type pulse
}
ctl.pulse {
type pulse
}
pcm.!default {
type pulse
}
ctl.!default {
type pulse
}
I can run Steam Alsa games and youtube videos at the same time (I
believe system wide). I can even connect a bluetooth headset and have it
work without additional setup.
Found the info here :
https://steamcommunity.com/app/221410/discussions/0/618458030650103916/#c618458030650649992
Don't know if this is a libasound2 or steam games bug/feature.
Thank you for your support.
Best regards,
Pedro Silva

No difference.
Reboot, login, start game, sound ok. Start browser, play youtube video,
playback hangs until game is closed.
cat ~/.asoundrc
###
pcm.!default {
type hw
card 2
}
###
ctl.snd_card {
type hw
card 2
device 2
}
###

Could you please add:
###
ctl.snd_card {
type hw
card 2
device 2
}
###
to your .asoundrc and try again?
Thanks

Hi Elimar,
I've updated libasound2-plugins and alsa-utils and still hit the same
issue, this time launching a Steam game (WarThunder).
Since I updated libasound2 to 1.1.7-1, no sound on the game with the
same error message:
ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave
Packages installed on my system:
dpkg -l | grep libasound2 | awk {'print $2,$3'}
libasound2:amd64 1.1.7-1
libasound2:i386 1.1.7-1
libasound2-data 1.1.7-1
libasound2-dev:amd64 1.1.7-1
libasound2-plugins:amd64 1.1.7-2
libasound2-plugins:i386 1.1.7-2
dpkg -l | grep alsa | awk {'print $2,$3'}
alsa-base 1.0.27+1
alsa-utils 1.1.7-1

gstreamer1.0-alsa:amd64 1.14.4-1
libsox-fmt-alsa:amd64 14.4.2-3
If you need further information, please feel free to ask.
