Solved! Can't ge connected surround sound to work with laptop, despite both connected to TV

[darksmistress]

When we have our laptop (windows) hooked up to our TV with HDMI, the sound comes out of our TV speakers (which suck). We have had surround sound (samsung) hooked up long before this, with any TV sound going straight to them but now it won't when laptop is used as source. No plugs to directly connect surround sound to laptop, however, tv's output audio is connected to surround sound.
Why would audio from HDMI be outputted through TV and not surround sound?

Check the audio settings in the laptop audio control panel.
If you can't set the laptop to output in surround sound then change the surround sound mode in the HTS.
