Hi Elimar,
"What is wrong with configuring a
asoundrc?"
It was not required before this package update. Regression?

Well, I don't know your environment. Please notice that the
.asoundrc method is usual. What is wrong with configuring a
asoundrc?
And yes, I can't do more here. I'll leave the bug open and maybe tag
it as wontfix in a few weeks

Ok, so it seems to be udev's task to set the priority of soundcards.
I can't do more here so I am closing this bug hereby.
Hi Elimar,
I have the same problem: sound has always worked, until installing 1.1.7
version. With 1.1.7 I have to write the .asoundrc file to make sound
work. This happens on both my laptops.
I might be wrong, but it seems to me that the problem has nothing to do
with udev... Do all Debian users (at least those with Intel sound card)
need to write the .asoundrc file to make sound work again?
Reopening, since I use unstable and 1.1.7-3 does not work without
.asoundrc file.

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.

Ok, so it seems to be udev's task to set the priority of soundcards.

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.

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 {

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

Even with the $HOME/.asoundrc file, I've nailed it down to not being able to play two sound sources at the same time. Reboot with USB card plugged, login, run game, sound works. Open browser (firefox), open youtube, play video, doesn't play, hangs playback until I close the game. Close browser and game, start browser and play youtube video, everything ok. Start game, no error message (as the subject of this bug) but no sound whatsoever. Needless to say that none of this happened before the upgrade. I haven't tried to downgrade libasound2 to previous version, but I can if it helps troubleshooting. Best regards, Pedro Silva

No difference. As the original bug reporter, please understand that my knowledge of Alsa is also limited. Unplug, reboot, plug, $ cat /proc/asound/cards > libasound2bug_reboot_thenplug.txt. Reboot. $ cat /proc/asound/cards 0 [HDMI ]: HDA-Intel - HDA ATI HDMI HDA ATI HDMI at 0xfe96 irq 67 1 [Generic ]: HDA-Intel - HD-Audio Generic HD-Audio Generic at 0xfe80 irq 69 2 [USB ]: USB-Audio - Razer Kraken USB Razer Razer Kraken USB at usb-:09:00.3-4.3, full speed $ diff /proc/asound/cards libasound2bug_reboot_thenplug.txt [no output] My concern is the "it worked before". Anything else besides Alsa and the kernel that could cause this issue? Best regards, Pedro Silva

Hmm, the priority of the sequence of sond devices is done by the
kernel (udev|systemd). If you are interested please run a test as
follows:
Unplug your usb device and reboot. After reboot plug in your usb
device and run 'cat /proc/asound/cards'.
Boot with a plugged in usb device and run 'cat /proc/asound/cards'.
Is there any difference?

With the $HOME/.asoundrc, pointed to card 2, the sound is back and fully
working, thank you.
You mean that a minor revision to this package caused it to now require
a manual configuration file? Why?

It seems that your HDMI device is your default sound device. If you
want to use your HDA-Intel to play sound you need a $HOME/.asoundrc:
###
pcm.!default {
type hw
card 1
}
###
To configure this system wide put it in /etc/asound.config

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:

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. Since upgrading libasound2 from 1.1.6-1 to 1.1.7-1 this morning, the script now gives the following error: ALSA lib pcm_dmix.c:1099:(snd_pcm_dmix_open) unable to open slave play FAIL formats: can’t open output file `default’: snd_pcm_open error: No such file or directory I ran speaker-test to try to isolate the problem.
