SiS7012 PCI audio problems

[mandre]

Hello,

I've problems making my integrated soundcard work with Knoppix 3.2. My compiter is an AIO A950 (http://www.ecs.com.tw/products/a950_spec.htm). Here is what lspci says :

01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] SiS650/651/M650/740 PCI/AGP VGA Display Adapter

This chip is recognized as "C-Media AC97 Audio Device" under WinXP and the sound works.
I tried i810_audio and cmaudio (as said in specifications on manufacurer's website) but both won't work. cmaudio even freeze my computer.

The *funny* thing is that headphone works under linux, but not speakers.

Anyone can help please ?

Try off the Kmenu -> Multimedia -> Kmix and see if the speakers are muted.
