no sound with alsa 11 and via82xx
 

current with default 2.4 kernel
I just upgraded from 1.0.11rc4 to 1.0.11 and sound disappeared with a via82xx chipset. The new patch does not seem to work. Lots of errors about blocked fifo upon KDE exit.

same problem a while back. running

& alsaconf

after install did the trick. hope it does for you.

I run alsaconf, alsamixer and alsactl store every time I touch alsa the alsa driver.
Went back to lib 11rc4, previous driver and the sound is still not working, but the fifo block error is gone.

There have been some problems with via82xx lately.

Supposed to be fixed now.

From the command prompt as root.
cat /dev/urandom > /dev/dsp
result is silence so this is nothing to do with arts.
lsmod shows the vi82xx module loaded

the cat /dev... trick has always worked on this machine in the past.

edit
There are loads of hal.hotplug DEVPATH not set errors in syslog

May 3 13:41:32 tungsten hal.hotplug[210]: DEVPATH is not set (subsystem net)
May 3 13:41:33 tungsten kernel: ALSA ../alsa-kernel/pci/via82xx.c:580: codec_read: codec 0 is not valid [0xfe0000]
May 3 13:41:33 tungsten last message repeated 3 times
May 3 13:41:33 tungsten hal.hotplug[295]: DEVPATH is not set (subsystem usb)
and many more after this

messages now has many complaints about wrong irqs on the usb chips.

Now upgraded to 2.6.16.16 generic kernel with mkinitrd to preload reiserfs and alsa 1.0.11 for 2.6.16.16 package.
A lot fewer errors - the KT400 agp aperture bug and the usb irqs are now OK

Still getting the via82xx.c:580: codec_read: codec 0 is not valid error and DEVPATH errors

DEVPATH lines were due to a hal FRG package, removed that and just the audio driver error

Ouch. The next time I see freerock I'll try to remember to ask if he's upgraded that yet. He doesn't like bugs in his packages any more than anyone else.

The FRG installation is old, never worked properly and unmaintained.
It would be nice to have a method to uninstall these third party Gnome addons and revert to pure Slackware.
