Redmi 3 Ido WhatsApp doesn't record audio
5.0 1

Redmi 3 using Android Pie, latest working nighty build was MK90.0-ido-201911011354-NIGHTLY.zip.
When I try to record an audio of any length, the only result I get is a 4kbyte, 1 second recording with just noise. Mic is working fine on phones calls.
WhatsApp was removed and installed again, clearing all permissions and data/cache.
Also, recorder doesn’t seems to save the last audio recorded in app, but I can share it on another app and play it normally. All permission granted.
I could revert to the latest working builds, but the latest nightly are much more responsive.
Any advice?
Thanks,

F.
