The newer version of alsa-lib would replace unsafe characters (like '.') with an underscore. Try changing /usr/share/alsa/cards/USB-Audio.conf. Dont add an entry to the USB-Audio.pcm.iec958_device list near the top, but go to the bottom, to the USB-Audio.pcm.iec958.0 definition, and change this: USB-Audio.pcm.iec958.0 { @args [ CARD AES0 AES1 AES2 AES3 ] @args.CARD { type string } @args.AES0 { type integer } @args.AES1 { type integer } @args.AES2 { type integer } @args.AES3 { type integer } @func refer name { ...(lots of stuff)... } default { ...(lots of stuff)... } } to this: USB-Audio.pcm.iec958.0 { @args [ CARD AES0 AES1 AES2 AES3 ] @args.CARD { type string } @args.AES0 { type integer } @args.AES1 { type integer } @args.AES2 { type integer } @args.AES3 { type integer } type hw # no @func card $CARD device 1 } (This will break S/PDIF on all other USB devices, but who cares ...)
