Hello everyone, I have been in this world of armbian for a year and I want to develop some projects on this OS ,and at this moment I need to record audio with h96max with rk3318 chip, the system says yes, it has analog input through the stereo plug . Is it possible to put a microphone on this board?
aplay -l
card 0: ANALOG [ANALOG], device 0: ff010000.i2s-rk3328-hifi rk3328-hifi-0 [ff010000.i2s-rk3328-hifi rk3328-hifi-0]
Subdevices: 1/1......
arecord -D hw:0,0 -f cd -t wav -d 5 test.wav works
but the output file is totally silent, using a hands-free cell phone
Where can I put a microphone on the board?
