When I capture videos, I want to use the Spdif input on my Sound Blaster Extigy sound card, but the only pin line input that works is "What-u-hear". But it is a pain in the ass to unmute the spdif input on the play control mixer every time I want to capture, and I always forget to. Is there any way I can configure programs like virtual dub or virtual vcr to automatically use the spdif input?
