Internal sound error

Nov 9, 2014

I bought a xiaomi mipad and flashed miui v6. But when i want to record the screen with the internal sound it doesn't work. It also cut the sound of the app and all the system until a reboot.
I bought this tablet to record so i'm busy this problem :'(. I read that the problem appear since some release of miui (i'm on 4.10.31 FR)

A solution exists (like downgrade)? Thanks.

PS: I try with scr recorder pro, rec and adb command (video but not internal sound)

PS2: Sorry for English :)
