Sorry I missed that. Did you try (Poweramp EQ) Settings > Equalizer > Block size/Block size for Hi-Res? What else? Don't bother. 'Fixing' bad audio quality is getting more & more involved. By now it would include: root, update 30+ system files, replace recovery so you can recover without full wipe, guess magic numbers and flags, 'fix' and recompile kernel without dsp, uncomment calibration files, run audioserver with some kind of 'timing' attack and the list goes on... At that point, either use external DAC (e.g. FiiO) + UAPP if you care about quality (but that's with cable). Or learn ubuntu/arch and run bluetooth audio from there. Then Viper4Linux will do what you're looking for.

Go to (Poweramp) settings > Audio > Output (2nd last Option), Click the one that says 'Active'. Choose where you have the problem (bluetooth?) and click the gear icon. There you find the setting for buffer size. Choose option big or huge If this happens in all apps, try android settings > developer settings. There are a few bluetooth audio settings. Just lower volume before tinkering.
