Silence during sound record on MSI M673 laptop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi. I'm trying to figure, why I can' record any sound with my M673 laptop.
Tried both internal microphone and external one. Tried to adjust all
settings in alsamixer. 

After turning on "Mic" (it was muted by default) I can hear my voice in
speaker, but nothing is recorded by alsamixer.

I'm using alsa 1.0.17 that is shipped with 2.6.27-rc7 kernel.
