Any way to increase the SNES9XTYL sound channels?

[Darqkiller]

Sorry if its a bit of a n00b question (Im kind of new to the Homebrew scene as far as PSP goes) but i've been playing a bit of Super Mario All Stars on SNES9XTYL and I noticed that the sound channels seemed a bit off, as if some were missing, the fire ball sound effect barely even made a sound and part of the music would cut out whenever I jumped.
So I was just wondering if theres some way to increase the sound quality/amount of sound channels (and I checked in sound options, there wasnt any sound channel option there)

Thanks in advance.
