Hey guys… here is the problem i’m having… i have my computer running win 7 home premium and i have the video card with an hdmi out hooked up to my tv. then the optical out goes from my tv right to my receiver. my other sound device i use is for Skype. a wireless Logitech set of headphones.The problem i have is that everytime i turn off my TV the only way i can get sound back on my PC is to reboot. I have gone into playback devices and i am unable to enable my AMD HDMI output. seems to default to my Logitech headset even if i use my PC sound last.again this happens as soon as i turn off my tv. even if it’s for a second. is there any way to get it to change to my hdmi device without rebooting?
