Alright, let me boot into linux and i'll see what I can do. I might have specified the wrong path by accident.
Edit: I was right, wrong path.
It should be like:
charon@crunchbang:~$ cd /home/charon/downloads
charon@crunchbang:~/downloads$ sh winetricks.sh
However, there's nothing specific to CS:S in it. It might be needed for other things though.
According to wineHQ after install through steam:
Select only "ALSA" sound driver in winecfg. OSS does not work anymore because Steam itself has sound open.
So run winecfg in a terminal.
Should pop this up. Make sure Alsa is the only selected sound driver ( I removed all the others one a while ago)

Afterwords, in a terminal to start steam before CS, run:
cd ~/.wine/drive_c/Program\ Files/Steam && WINEDEBUG=-all wine steam -applaunch 240
Assuming you installed it to the default spot. This should get it to work. If not, let me know and we can try some other fixes.
