My PC has the ASUS P7H55-M SI motherboard with the audio chipset VIA VT1708S. Under openSUSE 11.3 Milestone 7 (64-bit) I have no sound although the audio chipset seems to be properly recognised and supported by the OS.
I used the alsamixer application and I set the volume for all channels, including PCM to their maximum value but still I get no sound. When the OS boots I hear a “click” sound coming from the audio chipset when it is initialised by the kernel but then the sound stops and I hear nothing.
Note that I do not have this problem with Ubuntu 10.04 and openSUSE 11.2 but I have the same issue with Fedora 13. My guess is that Fedora 13 and openSUSE 11.3m7, having newer kernel/alsa software versions, exhibit this problem due to some bug introduced to the code.
Here is some extra information:
