(NB: since I'm not familar with piCorePlayer, the following is generic):
You probably don't need to activate anything, if USB audio is enabled in
the kernel (which is very likely), it should be detected automatically
(both by the USB subsystem, and ALSA)
Plug it in and check (example from a RPi3, edited for clarity):
Code:
--------------------
user@raspi3-64$ dmesg|grep USB
[ 2.351587] usb 1-1.3.4: New USB device found, idVendor=10c4,
idProduct=8a27
[ 2.353278] usb 1-1.3.4: New USB device strings: Mfr=1, Product=2,
SerialNumber=3
[ 2.354949] usb 1-1.3.4: Product: HIRESFI USB DAC ES9023
user@raspi3-64$ aplay -L
default:CARD=ES9023
HIRESFI USB DAC ES9023, USB Audio
Default Audio Device
user@raspi3-64$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: ES9023 [HIRESFI USB DAC ES9023], device 0: USB Audio [USB Audio]
--------------------
You'll have to configure squeezelite to use it, which probably can be
done from the web interface. If not, add something like -o
hw:CARD=ES9023 to squeezelite's options.
