Everybody says "all I want" without realizing, A requires B and C and D blah-blah etc.
All u want is surround audio you say, don't care about video, not routing video through AVR... OK then, that's what seems you said.
Very simple then, do a Toslink hookup between desktop and AVR, BAM! Toslink always work, available everywhere.
On your next post, hope to hear u say what have u done so far so nobody here have to guess.
Well ok.. I had a old receiver.... hooked it up and all I got was the video that blinked green on my monitor. That was a pioneer receiver... I'm not to computer savvy so not sure what you mean by what else I've done... I was just wanting to know if there was something specific in the receiver specs I should look for so, so when I buy a different receiver it will work.. and yes video, and audio through hdmi is what I'm looking for. you must be having a bad day... understandable.. didnt even know what a toslink was till you mentioned it.. so thank you for that...
