[Alsa-user] cmipci winfast 6Xsound spdif

[Dieter H. <di...@ho...>]

I use a winfast 6Xsound with a cmi 8738 Chip (alsamixer says: Card:
C-Media PCI CMI8738-MC6, cat /proc/pci says: Multimedia audio
controller: C-Media Electronics Inc CM8738 (rev 16).).

This Soundcard is equipped with coax and optical spdif in and outputs, 6
anaolog out channels, 2 line and 1 mic input.

 

With alsa-driver-0.9.0beta7 the following things are not working for me:

 

Optical spdif input: I can't enable optical spdif in. Toggling IEC958 5V
dosen't change from coax to optical. Always coax enabled

 

Line: "Line in" is unmuted when it shows mute and vice versa

 

IEC958 Output: Toggling doesn't change anything

 

Monitoring "spdif in" through "line out" is not working (I tried all
possibilities with IEC958 DAC to Out, IEC958 in Monitor). Enabling
IEC958 Out To DAC gives distorted sound on "Line Out".

 

What can I do, to debug this further?
