I wasn't sure in which thread to add this and i finally ended up here. Sorry, if this was the wrong one.

I also was not aware that the recording was not working on CM13. This is the curse of having multiple versions on different bases installed and jumping among them as it necessary. At the end I forgot what works and not under which version.
Apologies if this what I tested was already known, it was new to me and thought I add.

Are you sure this is CM base related rather than OS version or maybe HAL related?
The reason why I ask this, the recording is also broken in my build however that uses CM12.1 base. With the same base but an older OS version the recording works fine.
