I ran the player with debug output.
Code:
--------------------
myplayer start
Listening on 172.17.255.45... pid 1506 [/var/run/squeezelite.pid]
Executed [nice -n -5 /usr/local/bin/squeezelite-i386 -n Prades -b 16384:16384
-o iec958:CARD=DAC,DEV=0 -a 8:4::1 -d output=debug -f /var/log/squeezelite.log
-z 172.17.255.45]
--------------------
Then played an 88.2 record (player stays silent), then set the player
on/off a few times trying to play various other files (44.1, 96). The
player stays silent.
Here is is top and the bottom of the log file. I find it funny that, at
the bottom, squeezelite believes I am asking for a file with sample rate
88200. I was trying to play a regular CD rip.

BTW, I have no idea why Alsa doesn't want to resample anymore/with this
DAC. This is what I get with aplay:
Code:
--------------------
