Hi Dan wang
For recording, user need to set the some parameters through amixer. please try below command.
amixer cset numid=10,iface=MIXER,name='Capture Switch' on
amixer sset 'Capture' 100
amixer sset 'INPGAR IN3R' on
amixer sset 'MIXINR IN3R' on
Could you show me how to connect an electret microphone to the MIC IN jack?
I tried shorting the MIC BIAS and MIC IN connections but there is no voice recorded, thanks!
