[SOLVED] 9.0.2 at Pi Zero 2W - Failed to open ALSA device

[Tim Curtis]

Looks like a bug :-0

For Pi's with only a single HDMI port the device and mixer should be "default:vc4hdmi" (without a 0 on the end). I ran a quick test on a Pi-3B+ and no issues. I don't have a Zero 2 W but I think I know where the faulty logic might be.

You can try editing those two files and removing the 0. After doing that restart MPD via the command below.

Code:

sudo systemctl restart mpd
