Raspberry Pi OS Phone Jack Audio

Thu May 28, 2020 11:32 am

Hello,

since the new Raspberry OS ist live, i have a new problem.

The command amxier cset numid=3 1 doenst work anymore. I think its because the HMDI and Phone Jack are now seperated. But how can i force the audio output to phone jack now in console?

just from memory..

since the release of the RPI4 the A/V audio driver has been standard disabled because leaving it on is impairing the performance of raspbian OS.

I leave it to other readers to tell you how to turn in back on, but I imagine it must either be an entry in config.txt or a menu option in raspberry-config.

Thx for Reply.

in searched in the github repository for the raspi-config https://github.com/RPi-Distro/raspi-con ... spi-config and found the function do_audio.

You are right, i have to create file with a special content.

Code: Select all

pcm.!default {
  type asym
  playback.pcm {
    type plug
    slave.pcm "output"
  }
  capture.pcm {
    type plug
    slave.pcm "input"
  }
}

pcm.output {
  type hw
  card 1
}

ctl.!default {
  type hw
  card 1
}
Can you please swtich the thread to the troubleshooting forum?

Install the latest version of raspbian (now called raspberry PI OS), it has had changes in the audio handling, and has now two separate handlers for audio, one for A/V and one for HDMI, (previously one handler did both, in an either or fashion) and so you can now turn each one on and off with a simple desktop pulldown menu.
See it explained at 4 minutes 40 seconds into this video https://www.youtube.com/watch?v=qD67xfSvQrE&frags=wn
