Hello dear,

thanks for feedback.

This code was from a friend and related to alsa equaliser . So i've
tried :


Code:
--------------------
    sudo squeezelite -z -n Cuisine -m 00:00:00:00:00:01 -o USB0 -a 80:::0 -r 
32000,44100,48000 -C 5 -G 4:H -d all=info -f ~/squeezelite_cui.log
  sudo squeezelite -z -n Sam -m 00:00:00:00:00:02 -o USB2 -a 80:::0 -r 
32000,44100,48000 -C 5 -G 17:H -d all=info -f ~/squeezelite_sam.log
--------------------


it play when run some local music, but If I pick as example a YouTube
sound it stuck again :


Code:
--------------------
