Game Error: SV StartSound: volume

If you are getting this error when you try to run a game, it is caused by a sound setting that is set out of range.

Go to the game options and go to the audio and grab both volume sliders and center them, then exit options.

When you next run the game, you'll have to set your sound volume so it is comfortable but you won't have that error any more.

If this problem returns the next time you run the game, your config.cfg file might be set to "read-only" or you might have the offending settings in your userconfig.cfg file. You'll have to make the file writable, fix the problem, then set it back to read-only when you are done.

If the settings are in your userconfig.cfg file then you'll have to manually go and delete the setting (just look for the error value that the game is failing with, typically 510).
