Thanks Guys,
I have updated the Pi’s firmware as listed in this article, Poor mouse and webcam performance, and have got the kit working on both Raspberry Pi OS and Balena, but the sound input from the mic is still to low. On Pi OS, I was able to boost the gain using the audio control panel, and hey presto, no more problems, but can’t see a way to do this in Balena.
Is there a way to do this, as this is literally the only hurdle left to using Balena now.
Thanks
