i’m trying to play black mesa with my headphones, but the sound keeps on coming out of the speakers, even if i set headphones on the audio options.
is there a way to fix this problem? thanks 
Are you sure your headphone jack is working? I use headphones for Black Mesa with no problem…
sorry it was my fault, i think there was some conflict with a windows upgrade installing… i rebooted my pc and the headphones were working!
