HDMI Mute Fix


Post by SMC » Mon Feb 18, 2013 8:39 pm

I've been living with the fact that my ATI graphics adapter mutes the HDMI audio out whenever my AV receiver switches to a different input, or is turned off. I thought about programming my remote control to deal with this, or doing some Event Ghost thing. Then I thought: heck, I'm a software developer ... why don't I write a little software to fix this?

After several hours of messing around with handling various Windows events that might tell me I need to un-mute the audio, I gave up and went with a brute-force timer scheme. Every two seconds, it checks to see if the PC audio is muted. If it's muted, it un-mutes it. It uses no detectable CPU time, and about 1.5 mb of RAM.

I've been running it for a few days, and it works like a charm. There is no installer. Just one .exe file that you can put wherever, and run it. If you want it to run on system startup, put in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup
