Subject[2.6.0-test6] Troubles with ALSA via82xx
Hi,

I have trouble with linux-2.6.0-test6 and via82xx. With default
parameters I'm unable to play sound. I've tracked down the problem to
this change:

- use dxs_support=3 (48k fixed) as default, since there are so many
problems with dxs_support=0.

Loading module I see this:

via82xx: Assuming DXS channels with 48k fixed sample rate.
Please try dxs_support=1 option and report if it works on your machine.
PCI: Setting latency timer of device 0000:00:11.5 to 64

and when I try to play anything the player locks and I see the
following messages:

ALSA sound/core/pcm_lib.c:2156: playback write error (DMA or IRQ trouble?)
ALSA sound/core/pcm_lib.c:2156: playback write error (DMA or IRQ trouble?)
ALSA sound/core/pcm_lib.c:2156: playback write error (DMA or IRQ trouble?)

dxs_support=1 doesn't help since I have a VT8233A. dxs_support=2 is ok.
Looking at the code I see that VT8233A (without dsx) and VT8233 (with
dsx) are selected using dxs_support parameter. Is this the only way to
do it? 2.6.0-t5 worked for me, not sure that this is a bug but at least
it's a regression.

This is my audio device:

00:11.5 Class 0401: 1106:3059 (rev 40)
Subsystem: 1695:3004
Flags: medium devsel, IRQ 5
I/O ports at e000 [size=256]
Capabilities: [c0] Power Management version 2
