I found a bug with XAudio2 sound driver:
When i reset or load game the sound becomes louder, like the volume level is ignored (must be set to something like 30% to notice).
This bug not happens with WaveOut driver.
I use Snes9x 1.60 x64 on Win10x64.

Re: Volume bug in XAudio2
This has already been fixed in git (https://github.com/snes9xgit/snes9x/issues/603), you can try the latest automatic build.

Retroachievements build based on 1.60 also affected.
