So I finished building my game boy zero and went with the USB dac option. Tested the audio on my android phone and it worked perfect. I then plugged it into the pi and followed chiz's guide for setting it as the default device. I then had the same issue as many people on that topic with the error "failed to find mixer elements" and no sound at all. I tried to follow the solution posted on it but had trouble with the instructions (still a novice with all of this). Is there something I may be missing or could someone help out with the solution! Fell free to ask any questions about the situation I may have missed! Thanks so much!!

interesting... hope i don't have the same issue

just received my usb dac yesterday

I've built GBZ with USB-DAC and sound works ok.

DAC got from here:

Retropie (4.0) setup following this guide:

Only issue I got is when exiting Emulationstation I can see console message:

ALSA lib pcm.c:[...]snd_pcm_recover) underrun occurred

but sound works good in menus and in games (tested in GB, GBC, GBA, NES, SNES games).

That's the same usb dac i ordered!
Hooe mine works too
