[Alsa-user] via8235 DSX playback channels missing

[Stefan R. <sr...@is...>]

Hi,

I'm using a MS-6380E mainboard with VIA8235 south bridge and ALC650rev0
AC97 controller. With this configuration, DSX playback works only
limited: Subdevice 0 can be heard on both speakers, but from subdevices
1-3 only left speaker plays, the other stays muted. This behaviour
exhibits with both aplay and kernel OSS emulation.

Alsa version is cvs HEAD, lspci shows:

00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97
Audio Controller (rev 50)
        Subsystem: Micro-star International Co Ltd: Unknown device 4720
        Flags: medium devsel, IRQ 22
        I/O ports at dc00 [size=256]
        Capabilities: [c0] Power Management version 2

Any ideas?

Stefan
