I have: # aplay --list-devices **** List of PLAYBACK Hardware Devices **** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: SB [HDA ATI SB], device 1: ALC888 Digital [ALC888 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 3: Generic Digital [Generic Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: M1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi] Subdevices: 0/1 Subdevice #0: subdevice #0 And if I do alsamixer -c 1 I also get just one s/pdif in the middle of the screen, the graphics card appearantly have one. alsamixer -c 0 shows the motherboard interface, alsamizer -c 2 shows the pci one. Perhaps you have more than one interface. /// There is a debug tool /usr/sbin/alsa-info.sh if you install media-sound/alsa-utils You can possible get better help at linux-audio-user at lists.linuxaudio.org Regards, /Karl Hammar
