Certain VIA-based chipsets erroneously enable DXS support

Please attach the output from ``lspci -nv && amixer''.

OK, there is output of `lspci -nv && amixer''.
Thanks for Your attention

Simpl...

Please try:

sudo modprobe -r $(lsmod |grep ^snd |awk '{print $1}' |sort -r) && sudo modprobe snd-via82xx dxs_support=2

OK, I've got:

" pawel@kubuntu:~$ sudo modprobe -r $(lsmod |grep ^snd |awk '{print $1}' |sort -r) && sudo modprobe snd-via82xx dxs_support=2
FATAL: Module snd_via82xx is in use."

And the problem still exist :(

Same here :(
Please help...

I was stupid enough not to search 1st... oh well, here is my report, with more info:
https://launchpad.net/distros/ubuntu/+bug/68876

sudo kill $(lsof -t /dev/dsp* /dev/snd/*) && sudo modprobe -r $(lsmod |grep ^snd |awk '{print $1}' |sort -r) && sudo modprobe snd-via82xx dxs_support=2

Thank you for your help... but it still doesn't work, this time i get:
FATAL: Module snd_timer is in use.

:(

Ok. Please issue the following command (as one line), and then reboot:

echo "options snd-via82xx dxs_support=2" |sudo tee -a /etc/modprobe.d/alsa-base

Ok - I've done:
"echo "options snd-via82xx dxs_support=2" |sudo tee -a /etc/modprobe.d/alsa-base"
and now all seems to work good. No more "cpu overload" and sound working in all apllications.
Thank You very much
Best regards

Thank you so much for your help :) I hope this kernel patch will reach us as soon as possible.
Another question: what do I do with Knotify? It disables the arts output, and I don't have system sounds, nor kopete ones.

Please,

Consider this card as well

It has the same problem as the via82xx!!!

My laptop is an IBM Z60m, I tried to add

options snd-hda-intel dxs_support=2

to

/etc/modprobe.d/alsa-base

with no success, if i do so the card is not detected at boot time :-(

Please help

Hi, I still can't set the volume in KMix, nor in Alsamixer. PCM is not present in KMix, and in Alsamixer I can't give a value to it (dead). Will the kernel update fix this? Because volume management is imposible via these... :(

@Mirco: Your issue is completely different, since you use different hardware. Your hda_intel driver doesn't have the dxs_support parameter (because it's via82xx-specific, and well, you don't have that sound chipset). Please search other hda_intel bug reports.

Keep in mind there are a bevy of hda_intel patches that have yet to be merged into Dapper and Edgy by our kernel lead, and there's no ETA on that.

In short, don't confuse similar symptoms with identical causes.

@Johnny: Please describe your problem succinctly as it regards the "sound server fatal error." If that's no longer an issue after using the dxs_support=2 parameter, please file a separate bug report for the alsamixer & KDE issues. This bug report is _not_ the place for general audio support.

Same problem for me.
first time i start kde, it freezes for about 15 secs. then the message "sound server fatal error....." appears. this message appears every few secs.
cpu load for artsd is at 99%. when i click to disable arts at knotify dialog, the message doesnt appear anymore -> artsd is closed.
although i can play audio files with amarok, but i dont hear system sounds.

I commited the fix, then
System Settings -> Sound system -> Hardware -> Select audio device:
I selected ALSA there. And then after a restart I had system sounds with KNotify (Use KDE sound system).

yes, problem solved for me too with:
1.
echo "options snd-via82xx dxs_support=2" |sudo tee -a /etc/modprobe.d/alsa-base
2. reboot
3. then System Settings -> Sound system -> Hardware -> Select audio device: ALSA
4. reboot

thanks a lot

Users affected by this bug and have fixed it, should check out this too: https://launchpad.net/distros/ubuntu/+bug/69984
please

A fix is to modify /etc/modprobe.d/alsa-base

and make the option line read:

options snd-via82xx dxs_support=5

This seems to fix everything on my MSI KT6-Delta with VIA chipset with VIA CMedia 5.1 sound

This thread is duplicates of 68876 and 69984

Marking as fix released at it appears in the change log here: http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-source-2.6.17/linux-source-2.6.17_2.6.17.1-10.34/changelog

I experience the same problem under feisty with kernel :
Linux marion-laptop 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux

The options is not there by default in modprobe.d, I'm now trying with it, and report back...
But one is sure, the issue remains in feisty !

Does this still happen in hardy?

Also adding a note that we'll keep this open against the actively developed kernel but against 2.6.20 and 2.6.22 this will be closed. Thanks.

This bug was fixed in the package alsa-driver - 1.0.16-0ubuntu4

---------------
alsa-driver (1.0.16-0ubuntu4) hardy; urgency=low

  * Patches (debian/patches/):
    - post_16_20080307.patch (obsoletes post_16_20080226) adds shadowed
      variable and integer as NULL pointer fixes and HDA quirks,
    - add_suspend_quirk_hp_nc6220_nw8240.patch fully fixes LP: #151111,
    - readd refix_lp_68659_by_disabling_dxs_for_0x1458a002.patch to
      close LP: #68659. This patch apparently never made it into Feisty,
      Gutsy, or Hardy.

I think this will still need to be pulled into linux-ubuntu-modules. Reasigning to the apropriate package. Thanks.

This problem still exists in gutsy, at least in the 64 bit. should i just try the fix mentioned above or should i wait for a patch?

uname -a :
Linux real-ate-server 2.6.24-16-generic #1 SMP Thu Apr 10 12:47:45 UTC 2008 x86_64 GNU/Linux

SRU justification:

Impact: Enabling DXS for a certain (known to be broken) ID results in errors and freezes.

Fix: Add code to disable DXS through a quirk entry. Impact should be minimal, since the change only takes effect for a specific PCI ID.
(Commited as 3447d1b2f89556ce3da8675bf972c0bb047d45da)

Testcase: (from bug report) arts sound (kde) is not working at all, arts daemon freezes, etc. With DXS disabled it works.

Fix is commited to git but not yet to any release.

Accepted into -proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!
