geotravel Posted October 9, 2017 Share Posted October 9, 2017 When I have to use Jessie version dev with kernel NEXT 4.13.5. The alsamixer have different options to setup audio compare to ARMBian with stable kernel 3.x I must switch on DAC Reversed to have audio output in speakers. I don't know it is correct but works for me. The input mic is very sensitive and must be lower value to have good quality sound I don't know why is displayed option for MIC2 , the orange pi zero has only one microphone input Link to comment Share on other sites More sharing options...

martinayotte Posted October 9, 2017 Share Posted October 9, 2017 Nope, but it is probably explained somewhere in the SoC datasheet and/or in kernel driver sources ... Link to comment Share on other sites More sharing options...
