Hi,

CMEDIA USB2.0 High-Speed True HD Audio has iec958 output on device 2 and iec958 input on device 0.

root[~]# cat /proc/asound/cards 0 [Audio ]: USB-Audio - USB2.0 High-Speed True HD Audio CMEDIA USB2.0 High-Speed True HD Audio at usb-0000:00:12.2-2, high speed

I'm trying to create a mapping in USB-Audio.conf : # If a device does not use the first PCM device for digital data, the device # number for the iec958 device can be changed here. USB-Audio.pcm.iec958_device { # "NoiseBlaster 3000" 42 "USB Sound Blaster HD" 1 "USB2.0 High-Speed True HD Audio" 2 ...

But I never got a match on "USB2.0 High-Speed True HD Audio".

Please could you provide me correct config ? I will test it and report results so that you can append this card to ALSA.

Thanks (below lsusb output)

Hi,

CMEDIA USB2.0 High-Speed True HD Audio has iec958 output on device 2 and iec958 input on device 0.

root[~]# cat /proc/asound/cards 0 [Audio ]: USB-Audio - USB2.0 High-Speed True HD Audio CMEDIA USB2.0 High-Speed True HD Audio at usb-0000:00:12.2-2, high speed

I'm trying to create a mapping in USB-Audio.conf : # If a device does not use the first PCM device for digital data, the device # number for the iec958 device can be changed here. USB-Audio.pcm.iec958_device { # "NoiseBlaster 3000" 42 "USB Sound Blaster HD" 1 "USB2.0 High-Speed True HD Audio" 2 ...

But I never got a match on "USB2.0 High-Speed True HD Audio".

Please could you provide me correct config ? I will test it and report results so that you can append this card to ALSA.

Thanks (below lsusb output)
