If a USB Audio device fails to show up in the output of the command below it could be due to a hardware or power issue or that its not compatible with Linux USB Audio driver / quirks config.

ETA: the UAC2 fix was an old hack to help eliminate audio glitches that were the result of bugs in the Linux USB Audio driver. I don't think its even needed anymore.

A nice article comparing USB and S/PDIF, with a mention of Toslink as well, is USB versus SPDIF on thewelltemperedcomputer.com.
