I have the following setup: MSI (nvidia) NX7600GT with HDMI out and a cable to take Coax SPDIF in (which it then passes through out the HDMI together with the picture). To this I have a Sony KDL-40W2000 TV connected on the HDMI. I have a Gigabyte GA-965P-DS4 motherboard with ALC883. My setup works without problems under windows. Under Linux I get some peculiar behaviour: I have to load the nvidia driver before the sound is passed thru, so I guess it's something active on the GFX card that is being controlled by the driver. After I load the nvidia driver, I have to unplug the coax and replug it again before sound starts working. If I run the coax to a receiver with SPDIF/COAX in I don't get this behaviour, so I suspect it's the nvidia GFX card that is doing something interesting and it's triggering on a plug event. So my question is if there is a way (command) to simulate a unplug/plug of the COAX port on the ALC883, so I don't have to do this manually? My thought was to run this command each time before I run mplayer to make sure it works every time. I have spent quite a bit of time on this to verify that it's actually the unplug/plug that makes it work, but since I figured that out it keeps working all the time. Also, I am running alsa:device=hw=0.0 in mplayer. If I use hw=0.2 I get a lot of static on the right channel. With 0.0 I can use either 2 channel or -ac hwac3 and get proper passthru to the receiver (the TV doesn't cope that well with it though) which I thought was strange since I thought this was supposed to be hw=0.2 only. # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 2: ALC883 Digital [ALC883 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 -- Mikael Abrahamsson email: swmike@xxxxxxxxx ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
