Just bought a USB keyboard with special built-in volume control buttons --- volume up and down works perfectly. The mute button --- correctly "mutes" Control Panel's Sounds and Audio Devices Property (device volume/speaker). However there is still sound coming out of my speakers.
I haven't come around implementing a "Stereo Mix" recording pin yet because it's quite a messy job. There is however a piece of software with which you can achieve this: Virtual Audio Cable.
IT works great passing trough from Xbox (Loop S/Pdif in to out) and from PC, my only sugestion is , could you make the Loop On/Off option as a button or something better accessible cause i do have to switch quite often between PC and xbox
ALso i have a small problem playing movies, i dont know if its driver related, but when i passtrough to my external AC3 decoder and the sound falls to single channel (for example only center plays) often i loose all audio, same thing happens if the source is mono (AC3 encoder then kicks in) i can see in AC3Filter panel that this one channel is sent via SPDIF but i get no sound. can anyone suggest something ?
3) This is more hardware focused, but I have been itching to get the spdif in and outs working on this card since I got it, but the only way seems to be tying directly onto the chip with an outboard coax/optical panel. There is also a 10 pin (5x2) solder pad here where a header is obviously supposed to go. Doubtful, but I am curious if anyone else has had any luck with a similar laid out card in finding out what these pins map to and by chance if they trace back to the spdif in/out pins on the chip?
