Playing audio works in principle with the three USB->S/PDIF audio dongles I have here. When I tried two audio dongles simultaneously on the same USB bus, it worked for 44.1 kHz, but audio was distored if one or both ran at 48 kHz. When I put one dongle on the same bus with a keyboard, there were crackling noises in the audio output. port 5 addr 3: full speed, power 500 mA, config 1, USB Sound Device(0x0104), C-Media INC.(0x0d8c), rev 0.10 port 6 addr 4: full speed, power 20 mA, config 1, USB Audio DAC(0x2704), Burr-Brown from TI(0x08bb), rev 1.00 port 6 addr 4: full speed, power 500 mA, config 1, HA INFO U2 USB TO SPDIF(0x5050), HA INFO(0x1852), rev 0.01 uaudio0 at uhub4 port 5 configuration 1 interface 0 "C-Media INC.
