upmpdcli not playing to usb audio - protongx - 30-Aug-2021
Hi all,
I seem to have fixed this issue myself, so this is more for reference in case others run into the same problem.
System: Rpi4 - Snakeoil OS 1.2.1 (Gear Isolation U1) - UPMPDCLI - BubbleUPNP (Android)
Issue:
- BubbleUpnp shows UpMpd as correct device. However, there's no audio output from the Pi even when BubbleUpnp was playing
Looking further on SnakeOil OS Music Player - Audio State, it looks like the Pi actually was playing audio, but to the wrong output. In my case, it was playing to bcm2835 Headphonehw:0,0, where as it was supposed to play to USB Audio as set on the configuration screen.
Solution:
I've tried reinstalling upmpdcli through ssh to no avail. The trick seems to be setting the default audio output device as USB Audio through ALSA config.
I followed this guide (https://www.raspberrypi-spy.co.uk/2019/06/using-a-usb-audio-device-with-the-raspberry-pi/) and then rebooted the Pi. That have fixed my issue for now.
Hopefully it helps someone.
Note: this method seems to default to 48kHz sample rate from ALSA, so the search continues.
