[Alsa-user] Problems with VIA8235 Southbridge

[Dan S. - J. U. A. <da...@su...>]

Heya,

I'll try to include as many of the vitals as I can. Essentially, I can get
no sound to play. I am running 0.9.0-rc6.

typhoon root # aplay /usr/kde/3/share/sounds/ktalkd.wav
Playing WAVE '/usr/kde/3/share/sounds/ktalkd.wav' : Unsigned 8 bit, Rate
11025 Hz, Mono
aplay: pcm_write:999: write error: Input/output error

less -f on /dev/snd/pcmC0D0p produces a read error.

Hardware vitals:

  http://www.biostar-usa.com/products/socketA/m7viq/m7viq_specs.htm

  VT8235 Southbridge
  AC'97 2.2 Audio CODEC

Kernel Vitals:

  Gentoo Linux: 1.4-rc1
  2.4.19 Kernel

The modules compile and insert without any complaints.

(Disabling IRQs for the USB interface produces no change).

If theres anymore information I can give, I'll be happy to provide.
