OK. I installed that Root - Push Notification Fixer app did the changes and reboot, turned off Doze, turned off battery saving for all system processes, Google Play and apps I use with push notifications. I'll test this, hope it will work.

I don't have issues with Google Play app installation, not even with the background thing. The only thing I got is a delay of seconds until pages are loaded and when downloading starts. Maybe this is because of newer G-Apps within RR 5.7.4 kernel 3.10.103.

About audio issue: I even deleted AudioFX from system/app or system/privapp, but still not change. I also deleted all files the 2 audio fixes in zip modified or updated, but still no change. That maybe just works in 3.4.67 kernel version. The audio boosting is different between the two.

1) In RR 5.7.4 3.10.103, when play/pause a song, there is no sudden boosting. The boosting is much more soft and only occurs in small cases, but isn't noticeable at all. But the boost is not the issue, in fact it seems like max volume of internal speaker is set up too high and if you reduce the level from the volume keys everything is great. Also, the earpiece volume is same or lower than in stock. The REAL max volume of the internal speaker SHOULD BE the same when playing a ringtone through it, at maximum volume, but WITH HEADSET/HEADPHONES connected. In this manner, it seems the audio profile changes from internal speaker to headphones, and the headphones profile has CORRECT volume. The only issue is with the internal speaker profile and, yes, also with the earpiece profile which comes on during call. If we could adjust these somewhere and actually work, all volume problems will clearly dissappear.

2) In RR 5.7.4 3.4.67 (or even older versions of RR/CM), when play/pause a song, there IS a sudden boosting. But the max volume of internal speaker is NOT set up too high and there is NO DISTORTION at max volume. You only use the volume keys to reduce the volume, but as you doo this, the boost compensates, so you might have the same volume until you don't reduce the volume below 50% and it sounds really loud even at the first volume step after silence. Also, the earpiece volume HIGHER than in stock, which gives CLEARER voice of the one you're talking to (maybe this is because many versions include the spiker fix zip from the start, which also doesn't work on 3.10.103). To fix the sudden boosting, vol_fix.zip flashing through TWRP fixes it very nice, BUUUT the audio quality is like stock now, so silent songs will always remain silent, lock-unlock sounds are very silent, whereas in 3.10.103, there is a slightly boost which is very USEFUL.

I really think this slightly boost was a fix included in the newer security patch of the CM13 source ROM for the RR (over the huge and ugly mega-boost in the previous version), and I really like that they thought about it. So the max volume issue of the 3.10.103 is not related to the boost effect at all, it just seems like the max value of it is set too high. But I think they also changed the way parameters of the volume and boosting are read or executed, therefore the patches that worked for older versions DO NOT WORK for the newer ones. It may be in libaudio files, but that is pure binary and I think it's impossible to find out, until a new rom will be released so we could "steal" the libaudio files and actually work, because using libaudio files from older CM/RR didn't.
