simpz I have added a USB sound card to my rpi Emteria system. It works fine, but it is now the default sound device for everything in Emteria. How can I set the default sound device Emteria uses to something else ? Or even switch sound devices on the fly?
simpz Yup from the command line would be fine so the equivalent of something like: pacmd "set-default-sink <device>" Which is (I think) how you change this in ALSA in a desktop distro, but Android has a much lighter userspace ALSA.
simpz For some context, I can play out of a USB sound card with aplay easily enough, for the application I have in mind. But as soon as I plug in the USB sound card it becomes the default sound device, how can I make the built-in Rpi audio out jack the default again?
Jeph @simpz said: Yup from the command line would be fine so the equivalent of something like: pacmd "set-default-sink <device>" How can I access the Command line locally?
SanderK Enable the local terminal in the developer settings or connect with ADB and type "adb shell".
Jeph Thanks, I got the terminal working, just had some difficulty finding the setting. However the pacmd command does not seem to be recognized by the terminal. I have tried every audio interface I can think of and nothing... What interface does emteria use?
Jeph sudo is not recognized either, I believe "su" is used instead. Even with that, all I get is: " sh: pacmd: not found"
Jeph UPDATE: I now realize that Emteria uses TinyALSA for audio control. "tinymix" is the installed audio mixer/config tool After some editing of the audio_policy_configuration.xml file, I was able to restructure the default audio input and output.
