Arch Linux ARM

[RoEdAl]

Just quick note that stereo soundcard works fine on Arch Linux ARM for RPi (playback/record).

Of course one must manually add dtoverlay=audioinjector-wm8731-audio entry to /boot/config.txt file.

As my small contribution to community please look at my audio-injector-utils (Arch Linux package). Currently there are three tools:

• ainjectorctl - mixer tool, example usages:

  Code: Select all

  ainjectorctl record-from line-in
  ainjectorctl playback-to line-out
  ainjectorctl listen mic
  

• ainjectortest - sound card test based on this script designed for headless systems
• ainjectorchk - script checking if Audio Injector device is visible in the system

Please look also at my iecast-rec project. This is complete example how to broadcast audio (by IceCast) from sound card. arecord is used to capture audio and ffmpeg to encode audio and source IceCast. I do not recomend using ffmpeg to record audio from Audio Injector card. ffmpeg consumes a lot of CPU, arecord is a better choice. This solution works quite well even on old RPi B+.
