No sound on my tablet

Hi

I installed the new version of igo on my tablet but no sound.
if I install the version :

primo_9.6.22.290143 - 3 - sound_fix - scan_DCIM.APK

the problem is solved.
what i have to do to solve the problem with the new version?

Thanks

No one can tell what is newer or better in any new version, hence there is no reason why anyone should install a newer version. Or: when it is not broken, don't fix it!
