No way to know if the machine has even looked at the /etc/.asoundrc file, but it's definitely there. I'm listening to an Internet radio station on realplayer, and it's coming out my local speakers, but no sound from the TV. Of course, the file refers to quattro, which I don't have. I didn't do anything with jack, since I don't understand it at all. There is no q4 device, that I know of.
