Sound server fatal error: cpu overload, aborting

[Rapha]

Binary package hint: arts

Hello,
when starting the soundserver in kde3.5.5 on edgy the system hangs for some seconds (~20), then I get "Sound server fatal error: cpu overload, aborting".

This problem didn't occur with kde3.5.5 on dapper. I tested edgy with the 2.6.15-27-k7 Kernel (which with it worked in dapper), but the problem is still there.

The error does not occur, when choosing OSS instead of (automatic selection or alsa) in kcontrol->sound-system->hardware->choose audio hardware.

So maybe this is in the end alsa and not artsd related?

best regards,
raph

same problem, only since I updated to edgy

artsd -l0 gives me the following

and hangs!!

after the error messagebox appears...

[Sokraates (sokraates)]

I have a desktop, suffering the same problem, and an HP nx6110 notebook, which has no problem. I've tested both using with the Kubuntu 6.10 final live-cd.

Here are the relevant data:

Desktop having the error:
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8/235/8237 AC97 Audio Controller (rev 50)

Notebook without the error:

Maybe a duplicate of bug 68659?

[Cristian T (ctarsoaga)]

Yes, I think it is the same.

Though, the sound is fully working for me (after only minimizing the messagebox).

[Rapha (raphha2)]

I also think it's the same. At least the bugfix/workaround "options snd-via82xx dxs_support=2" does work for me (the initial bug reporter).
best regards,
raph

Many thanks to Daniel T Chen (see https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/68659)!

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

and a reboot solves!! the problem. Thanks Daniel! And thanks to Stefan Fleiter for pointing the duplicate.

Same to me.

Using Kubuntu Desktop, upgraded from Ubuntu 6.06 to Ubuntu 6.10 via "update-manager -c".

Whenever a KDE application calls aRTS (if I am in another Window Manager) or during aRTS startup (when I'm entering KDE) the system hangs for a few minutes. After that a message box appears saying "Sound Server Fatal Error / CPU Overload - aborting" and an OK button.

If I leave the message box alone I can use the system. If I click "OK" the system hangs again and, a few minutes later, the message box reappears.

Seems like there's something wrong with aRTS or libarts. This didn't happen prior to upgrading from 6.06 to 6.10.

I also noted that the libarts-ausiofile and the kdemultimedia packages weren't upgraded from 3.5.2 to 3.5.5 due to some dependencies not met. apt-get complains about the lack of various "-dev" packages that kdemultimedia and libarts-audiofile depend upon.

I tried to uninstall kdemultimedia (wich is only a metapackage, so no problem) and libarts-audiofile to see if the aRTS-hanging problem went away. The problem, unfortunately, persists, but now I can't reinstall libarts-audiofile due to those dependency problems.

This issue has not being fixed in Feisty, I'm experiencing the same...
I'll try to add the options in modprobe.d to see if it also solve the problem here...
