I had your symptoms too, and it turned out that making the ALSA output
code more correct in recent versions of squeezelite uncovered a bug in
my DAC firmware (and perhaps yours too). Triode has kindly placed a
workaround in Squeezelite that can be turned on using a 5th ALSA
parameter set to 1. E.g., see my /etc/sysconfig/squeezelite
Code:
--------------------
NAME="-n SqueezeliteQUAD"
AUDIO_DEV="-o hw:CARD=UD501"
LOG_FILE="-f /var/log/squeezelite/squeezelite.log"
LOG_LEVEL="-d output=debug"
ALSA_PARAMS="-a 40::::1"
OPTIONS="-D"
--------------------
You can't currently configure this in the web interface, but you can
directly edit /etc/sysconfig/squeezelite and change ALSA_PARAMS string
and then restart the squeezelite service, e.g., from the web interface
or "sudo systemctl restart squeezelite" from a command line.
