Ok, so here's my setup first:
PC--->HDMI Out on video card---> Yamaha RX-V573
I also have...
PS3-->HDMI Out--> Yamaha RX-V573
My problem is this:
If I start my computer with the PS3 as the active HDMI input, and THEN switch over to my PC(on my receiver) after it has booted up, my receiver will not appear in the list of "playback devices" for Sound until I reboot. I believe I found a way one time to accidentally get it to repopulate WITHOUT having to reboot. Otherwise, rebooting will always fix this issue. There has to be some way that I can detect the receiver without having to reboot my PC.
For the record, everything works fine when I boot up with PC as the active input on my receiver. Sound passes through to the receiver and works great. I'm really looking for a 'trick' to redetect sound devices.
I will likely need to provide some more information, but wanted to get the general gist of my problem down so I could see it for myself and see if anyone has some helpful tips on how to fix the issue.
Thanks! I hope this is the correct sub-forum to post in.
