Hi,
This might be a similar problem to what was just posted..
I have an ECS GF7100PVT-M3 (nvidia chipset) and am using the built in
soundcard. I am using alsa as a kernel module with support for IDT/Sigmatel
and NVIDIA codecs. I can get output fine; however, I can't seem to be able
to play line
I have a MSI-VR705 laptop with a ALC1200 A/D/HDMI sound card on board.
I can get the speakers to play music, but when I plugin a mic, line in, or
headphones nothing is sent to the headphones or collected from the
mics.
The headphones do not automute, the built in mic doesn't accept any
sound,
