Description Benjamin Collar 2005-10-09 09:24:53 UTC

Greetings

I was using 2.6.11 for far too long and now want to upgrade to 2.6.13. I've
installed gentoo-r3 but do not get sound. The alsa driver loaded is the
in-kernel driver, not the one from the package. But I also get the same failure
when I use the out-of-kernel versions (1.0.9b and 1.10.rc1)

This is the error I get when starting alsasound:
codec_read: codec 0 is not valid [0xfe0000]

This is the audio device in question:
0000:00:11.5 Multimedia audio controller: VIA Technologies, Inc.
VT8233/A/8235/8237 AC97 Audio Controller (rev 50)

I've tried a number of different configurations and it seems that sound will not
work under any kernel anymore. I've gone back to the original 2.6.11
configuration  (including devfs, but udev is installed as well), and it does not
work. In all configurations I get the error, "codec 0 not valid"

Is this reproducible on the latest development kernel (currently
vanilla-sources-2.6.14_rc3)?

Also, please attach the full dmesg output, and your kernel .config, and the file
/etc/modules.conf

I was hoping it was a hardware problem, but when I booted from a Ubuntu live CD
I could get sound.

Since the problem has only appeared after changing to udev, I feel that the
problem lies with my device and system configuration. As reported before, even
booting from a devfs kernel which previously worked, doesn't work.

I have not tried 2.6.14-rc3 yet, but will tonight.

2.6.14-rc3 does not improve the alsa situation
