Squeezelite on rock with USB DAC
Working on getting squeezelite working with a USB DAC to play with Logitech Media Server. You need Logitech Media Server otherwise squeezelite is worthless without it. I have several instances of LMS around my house
Download Squeezelite AMRV6hf from here
https://code.google.com/p/squeezelite/downloads/detail?name=squeezelite-armv6hf&can=2&q=
sudo mv ./squeezelite-armv6hf /usr/bin/squeezelite
sudo chmod ug+x /usr/bin/squeezelite
Plug Dac into USB and type
squeezelite -l
It lists all sound devices. I typically use the "front" device. Then type.
squeezelite -o front:CARD=DAC,DEV=0 -n ANYNAMEYOUWANT -s YOUR . SERVER . ADDRESS -a ::16:
i.e.
squeezelite -o front:CARD=DAC,DEV=0 -n RadxaRock -s 10.0.1.99 -a ::16:
Unfortunately I can't get it working in 24 bit so far. I'm close with a few pops and clicks and hopefully can get it. And anybody that has any ideas I'm all ears.
