Difficulty with 5.1 sound, Realtek HD Audio Manager
I am posting because I am having trouble getting my 5.1 system to work with my Acer Aspire 7551 laptop the way I want it to. My laptop is connected to my receiver by HDMI, but Realtek HD Audio Manager only supports stereo sound. I have attached a screenshot. Sound only comes out of the front L and R speakers. I understand that music is only mixed in 2-channel stereo, but I have six speakers and I want sound to come out of them.
When I test the speakers in Windows control panel, I can confirm that all of them are working (I have attached a screenshot of that too). I tried installing the Realtek HD audio driver from the Acer website and it didn't fix the problem. Also, I'm not sure how to find out what my sound card is. If someone who is more familiar with this sort of thing could help me with that, I would appreciate it.
Edit: Notice the two speakers shown in the screenshot of Realtek HD Audio Manager. When I click on these to test, sound comes from the laptop speakers, not my 5.1 set!
