Thanks for the prompt responses.
Here’s the workaround that resolved my particular situation.
I added the following to my node:8 container.
RUN apt-get update && apt-get install -y --no-install-recommends \
apt-utils \
sqlite3 \
alsa-base alsa-utils && rm -rf /var/lib/apt/lists/*
The addition of alsa allowed me to run amixer cset numid=3 1
in my start.sh
file as described here.
I then used node-aplay in this node:8 container to play the sound when requested through socket.io that I’m using for comms with the wpe container and connected devices.
This obviously won’t work for everyone, as it doesn’t give you direct sound output from the wpe container, but for my use case where I just need to trigger the occasional sound effect, it works great.
Thanks again for your help.
Best, Hoss.
