[SOLVED] Apple USB DAC setup?

[lcipher3]

I bought a new pi to run an old Zenith console.  Wanted to see if the Apply USB dongle would be good enough for temporary.  Not sure how to setup USB?  It's not in any of the Audio Output drop downs I can see (scanning output only shows HDMI) - googling brings up REALLY OLD posts for usb.
I'm sure I'm missing something really obvious but what?  Do I need a driver or ??

Code:

usb-devices|grep 'T:\|S:'

No drivers needed for USB audio devices. After u plug in a USB DAC it should appear in the Audio Config dropdown providing Linux/ALSA successfully recognized the device.

The command below will show whether Linux recognized the device.

Code:

aplay -l

From memory the device doesn’t present if you haven’t connected the headphones ? to the dongle.

Thanks - I rebooted and it showed up.  I also didn't have the RCA to 3.5mm connected to the apple dac - maybe the DAC doesn't initialize w/o a detected output ?

Anyway working now
