Hello, I hope you’re having a magnificent day.
I’m trying to force audio to play through the 3.5mm audio jack on a Raspberry Pi 3, because the Adafruit TFT screen I’m using doesn’t support audio.
I used WPE Webkit for the RaspberryPi as a starting point.
I’ve followed the advice in this similarly titled post, but when I run
amixer cset numid=3 1 on the command line I get the following
root@0dd50e6:/usr/src/app# amixer cset numid=3 1 bash: amixer: command not found
I’ve tried this with the unmodified WPE Webkit for the RaspberryPi repo and get the same result, however my actual app is multi-container, with the wpe as one container, and node:8 as the image for another (I get the error in a console in Host OS, and in both containers).
There is communication between containers as the node container is running socket.io, meaning a workaround that would work for me would to have the node container play the audio instead of wpe. Not sure if that helps, but I’m at the end of my tether with this and open to trying anything.
