Sound isn't working.

Whenever I start Garry’s Mod, the sound will not work. I’ve checked my sound options, and everthing is just as it should be. It hasn’t done this before, and I haven’t added any new addons at all recently. All other source games are working fine, and if I play music while in gmod, it can still be heard just fine.

System Hardware Specs:
Processor: AMD Phenom 9750 Quad-Core Processor 2.40 GHz
RAM: 8.00 GB
Graphics Card: NVIDIA GeForce 9500 GS
Operating System: Windows Vista 64-bit

Thanks in advance.

I have a problem sort of similar to this. It’s an easy fix if it’s the same one. Once you have loaded up a map in Gmod minimize to the desktop and open the little speaker thing in the bottom right hand corner; then press “Mixer” and make sure that the sound bar for hl2.exe or it may even be called Gmod isn’t at the bottom…my good friend.

Sounds -> Communications -> Do Nothing

Thank you Rombishead. That did it.
