We will require more information in order to diagnose the issue. Can you please state your full systems specs including your OS? If a laptop please state the make and model number of your unit. Could you also please state which methods you've seen so far?
If this is windows 10 and you're running off of a Realtek audio solution you may try reinstalling your device drivers or uninstalling the device from device manager multiple times before the sound issue that you're experiencing is averted. I must also ask, where did you get your copy of GTA San Andreas from?
