Hi,
I've got a MSI MS-7134 OEM Board here, little old I know. The sound
device is identified as
ATI Technologies Inc IXP SB400 AC'97 Audio Controller
The Chip is a C-Media CMI9780.
While the card seems to be identified correct, the card outputs only
mono signals and PCM is only capable to switch sound on and off. Have I
forgotten something to reconfigure, or is the card simply not fully
usable with alsa?
thanks for any adivse,
Sebastian
