Portal 2 Sound Issue (after trying everything!)
My issue: Portal 2 starts up fine, and I will have sound through the initial sequence (the valve head turn, and the source splash screen). Once I get to and through the first Portal 2 loading screen and to the area where I can chose to play, etc... nothing. Silence.

I have uninstalled and reinstalled the game several times, I have removed all community created content, and I have adjusted settings, I have verified the files. Pretty much done everything I know to do. The only thing I haven't done is uninstalled and reinstalled the Steam client itself because I'm unsure how that would help.

I have no other issues or crashes. No sound issues on any other game or program. Just this one.

Computer info if it's helpful:

AMD FX(tm)-4100 Quad-Core Processor 3.60GHz
Windows 7 Home Premium, 64 bit
4.00 GB RAM
Graphics: GeForce GT 630

That's a prime computer you got there, my only idea would be headphones.. or speakers. plenty of valve games dislike when you plug and unplug headphones and speakers from your computer and just renders everything silent.

I can pinpoint (almost) when the issue started, which is what's getting me. I have played Portal 2 on this machine before, but I went though and selected several community tracks to try - highly rated ones. I started it up and zoop. No sound. I've removed all those, and just got through deleting the local files, deleting the folder itself in the steamapps folder, reinstalling... still nothing.

I don't use headphones, I have a small speaker/subwoofer system that's been plugged in since I got it, and never had trouble before.

I'm going to continue to look for files I might not have deleted but if anyone has any ideas I'd be very grateful. It's one of my favorite games, and my son loves it too!

Thank you for the suggestion, though it didn't work (and yes, I did correct the spelling of cache) :). It gave me more info to work with though.

I'm still working on it. Thank you for the suggestions so far!
