SNES emulation: No/Cracking sound when playing

Emulation & Gaming
1

Maybe I should report this directly to emulators, but just to make sure.

So when playing any SNES game the video loads perfectly, but the sound is either absent (Snes9x) or cracking (Beetle bsnes).

Some HW info:

CPU:

model name	: Amlogic S905W rev d
Hardware	: Amlogic
