Hi,
I put your log output in code boxes for readability. Its the 5th button from the right on the toolbar when composing a post.
The log output shows 2 HDMI ports which indicates a Pi-4B but earlier you reported using a a Pi-3B+
http://moodeaudio.org/forum/showthread.p...1#pid13891
Code:Audio Information
Audio Device
Device: USB audio device
Chip:
Interface: USB
Formats: U8, S16_LE
Platform: Pi-3B+ 1GB v1.3
The log output also shows that your USB DAC has been assigned hw:2,0 by Linux/ALSA. It should be assigned to hw:1,0 by Linux/ALSA but for some reason not obvious to me it is not.
Here is what I see on a Pi-4B with stock moOde and a USB DAC connected. The USB DAC is assigned to hw:1,0 (card1) by Linux/ALSA.
