Hi.
My mainboard is a Tyan Thunder K8WE (S2895) (details can be found here
http://tyan.com/products/html/thunderk8we.html and here
http://tyan.com/products/html/thunderk8we_spec.html).
It uses Nvidia nForce Professional 2200 chipset which includes an AC97 compliant
soundchip.
My distribution is Debian sid, Kernelversion 2.6.16.something, which includes
ALSA 1.0.11rc2.
First of all does this chip support hardware mixing and full duplex?
I use GNOME (thus ESD) and I alawys have problems with sound when for example
using Ekiga. It complains that it either cannot access the sounddevice at all,..
or that full duplex is not available... :-(
Recording only works if I set up an .asoundrc (which I've attached below).
2nd Problem: The Mixer does not work correctly. When I change the settings for
Master (e.g. via gnome-volume-control or alsamixer) nothing happens at all. But
when I vary the value for Headphones it behaves as if Headphones would be the
Master.
Is there any way to correct this?.
Thanks in advance,
Chris.
Here is my .asoundrc (note that this is surely not perfect,... but I'm not a
sound expert ;) ):
