Any idea on how to test audio using microphone. My question is generic,
not specifc to to the pci8086,7270.
On neveda build 100, I tried to record using "Sound recorder" tool
available under
All Applications/Sound & Video. Record from input is availabe as 'Gain'
and 'Screen'
I tried to record using input 'Gain' and played back. Nothing making
sense heard.
Also I tried "cat test.oga > /dev/audio" ( test.oga is recorded file
using above method)
I hear noice from audio output. Is there any better way to test audio
input working?
