I started getting an issue recently that I can't seem to fix. I'm using a Samsung T220HD monitor which is plugged into my PC and my Xbox 360 using HDMI. For some reason whenever I change inputs, my HDMI audio still works for my Xbox, but when I check back on PC it tells me that I've disabled an audio device. I have to turn on and turn off my computer to fix this, but that only works as long as I don't change inputs again.
I've tried uninstalling and reinstalling my amd video driver and my realtek audio driver, but that didn't help. If anything I might have done something wrong because I had a similar problem before I uninstalled the drivers, but the issue was less consistent. What I mean is that switching inputs would cause the PC audio to stop functioning, but changing the inputs back and forth would sometimes fix it.
Well this is extremely frustrating. Normally I just plug in my headphones into my PC, but I've been using my Xbox 360 a lot lately so I wish I could just keep my headphones plugged into my TV and have everything work.
Also, I've confirmed that it can work, but if I change inputs on my tv it won't work so restarting my computer isn't much of a solution.
