Audio Stuttering

And auto frameskip isn't good enough to improve the audio?

Audio is going to sound terrible if it drops below 100% from time to time. You can try setting the HW scaler to 1x PSP. This may improve performance especially if you have a high resolution device (Acer A1-830 seems to be 1024x768 - this would reduce to 480x272 which should take 16% as much fillrate.)

Also recommend setting spline quality to medium, although probably that game doesn't use it anyway.

The texture coord speedhack only causes weird glitches in a few games, if it works here you may get some boost from it.
