It could possibly be one of these. The output from "aplay -L" would be useful. Also, "pactl list cards" and "amixer -c0 scontrols".
Which specific Xonar model do you have?
[mythtv@seveneves ~]$ lspci 01:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host Controller
I expect this is the card.
[mythtv@seveneves ~]$ lsusb Bus 003 Device 002: ID 0b05:189d ASUSTek Computer, Inc. Xonar SoundCard
But it actually is a PCIe x1 card.
What they've done is combine a USB audio chipset and a PCI USB controller on a single card.
If I get into the audio settings in MythTV, it will show the iec958 device, but setting the audio to use it produces no sound.
