Hey guys, Please help me with this frustrating lack of HDMI sound issue. Everything was working great up till today and, for no apparent reason ( I didn't change any settings or fiddle with anything), the HDMI sound stopped working. Here's my set up.. I have an Acer Aspire 5252-v440 laptop hooked up to a Samsung LN46D630 LCD tv via HDMI. When watching a movie on my tv through my laptop, my AMD HDMI is currently set as Default device, AND the green arrow is checked on the HDMI. HOWEVER, when I play a video or something, the speakers volume indicator moves up and down (showing that in fact, the speakers are outputting sound, even though my HDMI is set up to run. Weird? Please help!
