Trying to read "line in"
On a KT4V-L w/ AMD2200+ trying to read "line in". BTW this code works when MIC is in alsamixer's CAPTURE mode. When I change CAPTURE mode to LINE there is no response. This is validated by lack of data display on screen.
I note that (ALSA ver 1.00) allows no change to Line In but that is for Surround. So I am modifying the true line-in in the LINE channel. QUESTIONS:
1) how can I set up to read from Line In?
2) what is alsamixer's "EXACT MODE" and how is it used?
3) where can I go to learn about alsamixer's channels (i guess that's what they call them, e.g. PSM, LFE, DUPLICATE, ... etc.)?
