Latest available Atari800 core has sound issues

[RyFeR26]

On Android and iOS, Atari games using the Atari800 core have no / distorted sound.

Investigated, turns out that the latest Atari800 core version (Atari800 3.1.0 8bfa3b8) has the sound issue.
On Android I could revert back to a previous core (Atari800 3.1.0 20d59af) which works perfectly with sound for all Atari games. On iOS the Atari800 core is within the install package and can't be changed as far as I know.

Can this be looked at / update the core to the latest 5.2 version Android / iOS?

Same with windows x64

my old install of retroarch and a800 seem ok slight sound distortion but acceptable. Latest retroarch and a800 core a complete mess unusable audio
