If the "advanced" version of this mod (with noise suppression) does not work, please try to install the "simple" version (without noise suppression).

I installed the advanced mod (with 6db of noise supression, stereo mics, no sidetone or double speaker effect, audio bitrate on 96kbps - stock figures, as per the screen) and the phone is hung on "Android is starting..." (the same screen where it says "optimizing apps" - but there's no optimization going on, and it just says "starting apps".

If I remove the noise suppression mod (after flashing the system.img file so that I start from scratch) (and ensure the other settings are the same), it works! It boots up and both mics work!

Unfortunately, it seems the M Preview has issues with bluetooth sound on the N5 (some say audio streaming works, but connecting to another device won't work as well), and even though I don't use it, I'll wait for an update before jumping ship. So - I'm reverting to 5.1.1 - but now, everyone knows that the simple mod (without noise supression) works now on M Preview 2.

It appears that nothing has changed since the first edition of M Preview (MDP1) as the simple mod worked there, too.


I see two possibilities here:

1. Google still has not properly updated the AOSP sources. On MDP1, my phone would not boot even with an unmodified libaudioflinger.so build from AOSP.

2. Google's ROM is moving further away from AOSP, now making even libraries proprietary.


Either way, I'll continue to work on this once the sources for the final release drop.
