Audio out via jack on Pi Zero #265

Hello, Is there a way to get this USB sound card to work in order to have audio output via jack on Raspberry Pi Zero (BMC64 Lite)?

Thanks

Can you try adding

audio_out=analog

To cmdline.txt (everything goes on one line).

I think that’s supposed to use the output jack. But quality may not be great.

Sorry, didn’t read thoroughly enough. If it’s USB it would require a driver which doesn’t exist in the circle library bmc64 uses.

Any support regarding any device depends mostly from Circle. This table says that USB-audio device is supported only with RPi4/5: https://github.com/rsta2/circle#features
