Description Philippe Condé 2017-03-14 08:36:17 UTC

Hello,

I installed the a snapshot on 10 march via zypper dup.
I saw that kernel 4.10.1-2 was installed.

After reboot I didn't have sound.
my system is a HP Proliant ML350 with a XONAR DGX sound card. This card was configured and worked since 3 years.
I have also a Nvidia Quadro 4000 video card with sound capabilities (snd_hda_Intel). This card was not configured in the sound. For the video card I use the nouveau driver;

lsmod shows different snd_hda_* modules were loaded. I tried to remove and reinstall the Xonar card in Yast but this fails: "Kernel modules snd_virtuoso for sound support could not be loaded. can be a problem of IO or IRQ"

Now I cannot use the NVIDIA sound support because my screens doesn't have embedded speaker.
I need to configure the XONAR.
I blacklisted the snd_hda_intel in /etc/modprobe.d/blacklist.conf but with no luck.
I tried all previous kernel (4.10.0, 4.9.11.1° with no luck. The Xonar card cannot be configured

after reboot: I see the following modules for the sound
lsmod | grep snd
snd_oxygen 28672 2
snd_oxygen_lib 45056 1 snd_oxygen
snd_mpu401_uart 16384 1 snd_oxygen_lib
snd_rawmidi 36864 1 snd_mpu401_uart
snd_seq_device 16384 1 snd_rawmidi
snd_pcm 131072 1 snd_oxygen_lib
snd_timer 36864 1 snd_pcm
snd 86016 11 snd_oxygen_lib,snd_oxygen,snd_timer,snd_mpu401_uart,snd_rawmidi,snd_seq_device,snd_pcm
soundcore 16384 1 snd

The mixer are present in tray array. If I start amarok i see in the mixer the event from amarok but no sound.
I'll attach the hardware info and the udevadm for the /dev/snd/*

on thing is strange fro me/ the hardware info says that the Xonar Card uses IRQ27 but the udevadm says that the device use IRQ 51. Don't know if this is relevant

Regards
Philippe

Comment 3 Takashi Iwai 2017-03-20 13:06:26 UTC

Did you try to rollback via btrfs snapshot?  Since the older kernels (4.9.x) shows the same problem, it's not really a kernel regression, I suppose.

Also, how did you test it?  Try to run like
  aplay -Dplughw:0 -vv /usr/share/sounds/alsa/test.wav

If this doesn't work, check your mixer setup.  Run like "alsamixer -c0" and try to adjust them manually.

Comment 4 Philippe Condé 2017-03-20 20:45:32 UTC

Hello,

I use ext4 and not btrfs (root filesystem is too small for btrfs).
What I did

1) I found a zero byte /etc/modprobe.d/50-sound.conf and restored the Yast.save version
2) the alsa matrix says that the Xonar DGX uses the snd_oxygen module but Yast tries configuring the card with snd-virtuoso module which fails.
3) I updated the /etc/modprobe.d/50-sound.conf to use the xonar DGX as card0 with snd-oxygen.
4) after reboot the status of alsasound is inactive (dead) . I can start it  via "systemctl start alsasound".
5) "play -Dplughw:0 -vv /usr/share/sounds/alsa/test.wav" seems working but no sound.
6) I  can start alsamixer -c0 : I can change the level and the mute but still no sound. (see attachment)


in kde mixer I can go to the configuration (see png) there is no sound with the button left right but in the mixer I see coming briefly a libcanberra left or libcanberra right.
So all seem working but no sound. 
I don't have another PCI-E system to test the card but I'm asking me if the card is not dead

Regards
Philippe

Comment 7 Takashi Iwai 2017-03-22 14:18:51 UTC

The snd-oxygen driver is the correct one for your device.  YaST sound module doesn't seem to check the PCI SSID correctly and takes snd-virtuoso instead because it supports the other similar devices with the same PCI ID but different PCI SSIDs.

It's still possible that some mixer setup got screwed up.  Try the following:
- Go to runlevel 1
  # init 1
- Login on Lnux console as root
- Unload snd-oxygen
  # modprobe -r snd-oxygen
- Remove (better to backup) /var/lib/alsa/asound.state file
- Reboot

If this still doesn't work, run "alsa-info.sh --no-upload" as root, and attach the output to Bugzilla.

Comment 8 Philippe Condé 2017-03-22 16:49:08 UTC

Hello,

i run to level1, removed the module snd-oxygen via "modprobe -r snd-oxygen", removed the file /var/lib/alsa/alsasound.stat and rebooted: still no sound.

I attach here the output file from alsa-info.sh.

Many thanks in advance
Philippe

Comment 10 Takashi Iwai 2017-03-22 18:08:06 UTC

Via which output are you testing?  Judging from alsa-info.sh output, it's currently set up from the front headphone jack.

Comment 11 Philippe Condé 2017-03-22 18:25:57 UTC

Hello,

Yes the connection cable is in the front jack (green) It was so all 3 years. Never changed it
I have done a test with a new cable and with a new Xonar DGX card but there is still no sound;

alsasound is not active after reboot. I  started it but still no sound

Comment 12 Philippe Condé 2017-03-23 16:23:51 UTC

Hello;

I did some tests:

alsaconf doesn't find the card "No supported PnP or PCI card found.    Would you like to probe legacy ISA sound cards/chips?"
but these messages are also displayed when alsaconf starts
"Building card database..
/usr/sbin/alsaconf: line 588: /lib/modules/4.10.4-1-default/modules.pcimap: No such file or directory
/usr/sbin/alsaconf: line 588: /lib/modules/4.10.4-1-default/modules.isapnpmap: No such file or directory
"
alsaconf -m gives the same result.


file var/lib/alsa/alsasound.state exists but has a length of zero. I suppose that this is the reason why i receive "no state present  when asking the status of alsasouns
"# systemctl status alsasound

Comment 13 Takashi Iwai 2017-03-25 08:21:34 UTC

The alsaconf and alsasound systemd service can be ignored, so far.  The only impaortant thing is the current mixer setup and the device setup.

There has been really no code change for long time for this driver, thus I guess it's either a breakage in user-space or in your hardware.
At least, try to play a sound directly via aplay, e.g.
  aplay -Dplughw -vv something.wav

Also, run "alsamixer -c0", and change "Analog Output" enum to a different one, and try different outputs whether the issue is limited to the front headphone.

Other than that, I have no clue, so far.

Comment 14 Philippe Condé 2017-03-25 16:07:25 UTC

hello,

I tested all channels (analog stereo, duplex stereo, surround 5.1 etc) without success.

I booted then in the configuration menu and changed the IRQ for the Xonar DGX from 5 to 7, 
After reboot in Tumbleweed I had still no sound. I tested again all channels and it worked  for the duplex stereo.
:-)


I don't understand why it worked by changing  the IRQ and why it stopped.
I suspect that something changed in the snd_hda _intel because when the problem  occurred I found that this module was loaded for the media on the Nvidia Quadro display card  (DVI or display port)  and I'm. sure that this module was not loaded before;

Thanks for your advices
Philippe
