Hi,

 

I tried to use default audio device, audiocodec hw:0,0 with arecord to record some sounds from mic. The file contains some noise. Any ideas how to activate mic?

Hi

Try this:

root@orangepipc:~# alsamixer
root@orangepipc:~# arecord -i -f S16 -r 22050 /media/test.wav
Recording WAVE '/media/test.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono
^CAborted by signal Interrupt...

I just tested it on an SSH console in WXP and the /media directory is shared by samba to test the result.

HTH

not sure if you figured it out over the years but one thing that you need to do is run alsamixer, hit F4 then on mic 1 press space to enable it. took me a while also. this was for the orangepi prime and then you can record with arecord
