Distorted sound starting on commit 10945cfc809171c96007f62ec654c3a078096162 on linux

Hello

I'm having distorted and unsynched sound starting on commit 10945cf .

My platform is EMUELEC odroid n2+ aarch64 Linux 4.9 (BTW EMUELEC uses OPENGLES not OPENGL)

I notice that

• If I set up retroarch option voodo0 3fx performance to system multithread, everything works fine again when using video driver => GL

• If I use retroarch video driver SDL2 I don't need to make that change.

Finally, I did a change in the code and it fixed the issue

#ifdef ANDROID
if (preffered_hw_render == RETRO_HW_CONTEXT_OPENGL) testmax = 4;
#endif

Can you review it? I will publish a PR

thx
