TS app crashes when using CELT codec

TeamSpeak freezes and crashes immediately when I join and start to talk in a channel that has CELT Mono codec.
If I join with microphone muted, it won't crash, and i'm still able to chat, but as soon as I activate the microphone, it freezes and crashes.
This happens either with and without headset

Steps to reproduce:
-Join a server
-Mute microphone
-Join channel that uses CELT Mono codec
-Activate microphone
-Talk--->crash
OR
-Join channel that uses CELT Mono codec, with microphone activated
-Talk

It happens every single time.

I installed a TeamSpeak server on my PC for testing (ts3-server-win64-3.0.11.3)
Joining a channel with Opus Voice makes no problem. Editing channel to use CELT Mono makes the app crash, at every quality level, and rejoining has the same effect.

The channel that I used the most (and where I found the problem) switched to CELT Mono codec just in the days when I flashed Cyanogenmod 12(March 2015) on my phone, that was running stock Samsung Android 5.0. It worked well before, so it could be just one of the two factors, but I wish not to flash Samsung Rom back again for testing. If someone is running it, please try.

I'm running CyanogenMod 12.1 on a Samsung Galaxy S5 (klte), build 2015-09-13-NIGHTLY
Android version: 5.1.1
Kernel: 3.4.0-cyanogenmod-g951e2ff
TeamSpeak version: 3.0.19.3

I hope I didn't forget anything, and I'm here for further information.
Thanks in advance
