how did you test spdif out? you need to choose the PCM "spdif" (aka "iec958") for the proper output over SPDIF. > I was also expecting that "Item: IEC958 Input Monitor" would route the SPDIF > sound from my DVB card (whose output I have connected to the SPDIF input on > the main board) to the optical SPDIF output when I set that switch to on, but > again toggling that switch does nothing: the light is always on and the sound > is always off. spdif input on ALC650 didn't work until this morning. i applied the patch from James to cvs, so now it should work (as long as sf's anon-cvs repository is properly mirrored).
