Emulators for Android

[sonsaat]

I have been playing the ZX Spectrum games with the RetroArch emulator on my phone, but now there is one problem I don't have the sound when I play the games. I try reinstalling the emulator but doesn't work, reset the controls, and configuration still no sound. My question is how to find another emulator that supports playing retro spectrum games with an emulator on an android phone, any help would be nice.
