No more sound after snapshot 20240124

phil524 · January 25, 2024, 5:10pm

I have a Xonar DGX that worked without problem.
I use KDE and pipewire + wireplumber.
My Hardware is

hpprol2:~ # lspci -vnn | grep -A 1 -i audio 
0a:00.1 Audio device [0403]: NVIDIA Corporation GK104 HDMI Audio Controller [10de:0e0a] (rev a1)
        Subsystem: NVIDIA Corporation Device [10de:1096]

0e:04.0 Multimedia audio controller [0401]: C-Media Electronics Inc CMI8788 [Oxygen HD Audio] [13f6:8788]
        Subsystem: ASUSTeK Computer Inc. CMI8786 (Xonar DGX) [1043:8521]
hpprol2:~ #

I have blacklisted card0 (Nvidia) and I forced use of card1 via 2 files in /etc/modprobe.d
file 50-alsa.conf
options snd_oxygen index=1

file 50-blacklist-sound.conf
blacklist snd_hda_intel

This worked but with the last snapshot Amarok hangs and cannot play any track. Video in firefox hangs also (Black screen).
Here the status for the user services

And testing the sound shows also errors

It seems that now the sound subsystem try to use card ‘0’.
Is there a change with the /etc/modprobe.d use?
How can I restore the use of card 1?
Many thanks in advance

Closing all tabs in firefox solves the video problem with firefox. With Amarok the problem remains, it is not possible to start any track (mp3 or ogg). No error in journalctl. If I use vlc I can play it.

keellambert · January 26, 2024, 8:21am

I had
similar problem last week, I noticed 3 Kernel packges had been removed, so reinstalled them.
Then used Yast and did a search for Sound packges, and Re-installed all. Mostly ALSA + one wire? package. All worked ok thereafter.

have fun.

phil524 · January 26, 2024, 9:02pm

Thanks, I reinstalled all alsa, pipewire and wirreplumber packages without success.

I have found one error which occurs only since last snapshot installation during each boot

Jan 26 21:42:25 hpprol2 alsactl[1326]: alsa-lib main.c:1554:(snd_use_case_mgr_open) error: failed to import hw:1 use case configuration -2

If I login the first attempt to display a video with Firefox fails, if I open a second tab in firefox and ask the same video it works.

Amarok is still failing, the soundtrack cannot be started.
I’ll open an bug report

Regards
Philippe

I had the same problem with Amarok. The solution I found was to add phonon4qt5-backend-gstreamer. now it works fine.

phil524 · January 27, 2024, 9:41am

Thanks,

but on tumbleweed this backend doesn’t more exist.
I have open a bug report on bugzilla
https://bugzilla.opensuse.org/show_bug.cgi?id=1219251

It is not a kernel problem because with the previous kernel the problem is also present

Josh385 · January 27, 2024, 2:12pm

I’ve noticed that the 20240124 snapshot tried to remove the phonon4qt5-backend-gstreamer.

Don’t know, why, but it might explain your issue.

schweds · January 27, 2024, 4:16pm

On tumbleweed also. searched phonon4qt5-backend-gstreamer opensuse and found a community package by 13ilya.

phil524 · January 27, 2024, 4:22pm

Many thanks,

I downloaded from opensuse history http://download.opensuse.org/history/20240104/tumbleweed/repo/oss/x86_64/ and all is now working

I locked this package.

Philippe

malcolmlewis · January 27, 2024, 4:52pm

Hi All, it was deleted for a reason… https://build.opensuse.org/request/show/1139342

phil524 · January 27, 2024, 5:30pm

Thanks for the info.
So wayland has a problem but I use Xorg and
1 amarok doesn’t more work
2 firefox has problem playing video
3 sound at start of kde session doesn’t more work.
many errors

In the resquest it seems that phonon4qt5-backend-vlc can also be used. I 'll test it tomorrow

Regards
Philippe

phil524 · January 28, 2024, 7:43am

I installed phonon4qt5-backend-vlc and removed phonon4qt5-backend-gstreamer.
After logoff and login it seems that there are no problems with the sound. Poblem solved. I hope that this backend should be marked as a requirement for Xorg.

Many thanks for your help.

sfalken · January 28, 2024, 5:47pm

The gstreamer backend for phonon has been deprecated for quite some time. I believe I saw a SR recently that is swapping it for Tumbleweed anyway, and new installs should default to the -vlc backend.

phil524 · January 28, 2024, 8:18pm

Thanks,

The delete of phonon4qt5-backend-gstreamer was done in snapshot 20240124 and in /var/log/zypp/history I have

2024-01-25 15:36:49|command|root@hpprol2|'zypper' 'dup'|
2024-01-25 15:36:49|remove |phonon4qt5-backend-gstreamer|4.10.0-1.22|x86_64||

but there is no information that the user must replace it by phonon4qt5-backend-vlc in the announce of the snapshot, nor in the “zypper dup” process.
Maybe they missed that but it was a real problem fortunately quickly resolved via this forum.

Regards
Philippe
