Troubleshooting

No backbox sound in some VPX games

I have found that sometimes depending on the soundcard or driver, that all the sound is sent to the center channel speaker (but there isn't a center channel speaker in SSF!) The fix for this issue is quite simple -- just download and install equalizer apo

This also gives you the ability to adjust the sound level of SSF sounds vs backbox sounds, which I've found to be out of balance in most cases as the SSF sounds are usually lower than the backbox sounds. One of the easiest ways to do this is simply edit the C:\Program Files\EqualizerAPO\config\config.txt as follows:

#Pre amp and EQ for all speakers
Preamp: -12 dB
