I've had my Nightengale for about 6 months now, and it works great except for one thing. First of all, I have my sound card connected strictly with the Toslink output to my receiver. It works perfect for DVD playback, MP3, CDs.. etc.. But the one thing that I can't seem to figure out, is how to have the card automatically route AUX sound input to the output. For some reason, the only way I can get the routing to work is to open up the mixer settings, and enable the "Loopback spdif" flag. Then AUX routing to my receiver works great! However, now with this setting enabled, all regular sound processing stops. The DVD, MP3, CD ect.. don't produce any sound. It's quite frustrating. I think what I'd love to see is some sort of option in the sound card that takes AUX or LineIN sound and processes it out the spdif connection, rather than a simple routing... Ok.. I'm done with my little rant.
