Mic+Speakers Don't Work After Radeon 6850

I installed a radeon gigabyte 6850 graphics card in to my computer a long time ago and after I made the switch from Nvidia to Radeon my input jacks and output jacks stopped working. Usually I can live with it and use my laptop or phone for skype but I've just bought a game on steam and I can't use steam voice chat on a different system then play on my gaming system at the same time and playing games with my friends without voice chat is unacceptable.When I plug a mic in it says its working and it shows up in realtek hd audio but when i try to use it with anything it doesnt work. The bar doesnt even go up when i test it in windows 7 so it must be muted. I've tested the mic with a laptop before so it definitely works. I've reinstalled realtek hd drivers. I think the problem is I'm using hdmi to connect my tv and use it as a monitor and apparently using hdmi sound from amd cards mute all other sounds. I need the speakers on my tv as they are my only speakers, and buying new speakers or a sound card is not a possible option right now. And even if I could get speakers, my tv only connects via hdmi anyway so the sound would still be muted so I really need this fix. how I can get windows 7 sound to work while using hdmi from a radeon graphics card to output sound to my speakers? Does anyone use hdmi to connect their display to an amd graphics card?
