I tested some games on Suse 10.0 RC1, and there occur some strange sound (card)
problems, which did not occur in Suse 9.3.

Game 1, Neverball:
dominik@natrix:~> neverball
SNDCTL_DSP_SETFRAGMENT: Invalid argument
Warning: Couldn't set audio fragment size
Audio write: Invalid argument

Game 2, Unreal Tournament 2004:
dominik@natrix:~> ut2004
ioctl SETFRAGMENT grab: Invalid argument
ut2004-bin: al_mixer.c:735: _alSetMixer: Assertion `mixbuf.data' failed.
Signal: SIGIOT [iot trap]
Aborting.

The UT2004.log says:

And there is another strange thing: If I made some changes in the KDE Control
Center -> Sound System, and I want to apply them, there's a popup "Starting
Soundserver" and nothing more happens, the popup does not disappear any more, I
have to cancel it. And if I click on "Test Sound" in the control center, an
error occurs: The Soundserver (artsd) crashes with signal 11:

Unfortunately I can't isolate the error. Is it an arts/alsa bug, kernel, or
sound driver, I don't know.

My hardware:
AMD64, Soundchip (onBoard): VIA VT8237 (Driver: snd-via82xx)
