Hi all. I just recently got to testing this, and have no idea why I am not getting sound via my optical output when plugged into a set of Logitech Z680 speakers. My specs are as follows: kernel 2.6.33, Alsa-driver-1.0.21, Alc888 chip as displayed by aplay -l: **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC888 Digital [ALC888 Digital] Subdevices: 1/1 To get the alc888 digital output subdevice to show up on this Clevo W860CU laptop, I have to pass something like model=3stack-dig to snd_hda_intel. All the IEC-relevant Amixer controls are unmuted, as shown here: Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined cswitch cswitch-joined Playback channels: Mono Capture channels: Mono Mono: Playback [on] Capture [on] Simple mixer control 'IEC958 Default PCM',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [on] As I mentioned in the subject line, output via the Alc888 digital subdevice works fine via the HDMI port i.e., when connected to a TV and the video output is switched to an external display via Fn+F7 on this particular machine. Is there any reason given my configuration, as to why I shouldn't be able to simply hook up the Z680 to the S/PDIF jack via an standard Toslink to mini Toslink adapter, have MPlayer dump audio to the digital subdevice, and hear sound coming out of the speakers? Perhaps I need to somehow tell the driver that audio should be routed out the S/PDIF jack instead of the HDMI port? I have not been able to entirely rule out a bad physical connection i.e., bad connection to the S/PDIF jack from the mini toslink adapter, broken optical cable, non-functioning optical input on the Z680, etc. Unfortunately, I don't have any other devices here that I can test with, so attempting to rule out the above possibilities is not going to be very possible. OR, perhaps I am missing something else entirely with my above sound configuration?
