So I installed a custom rom on my phone and my bluetooth sound wasn't working. Btw I am not an expert so don't expect anything from me :>. And I stumbled upon a zip with the audio.a2dp.default.so file that fixed my problem but with a twist. Audio is speed is doubled , volume is very high and the audio is high pitched(I installed that zip with TWRP). I don't know how to read or edit that file because when I open it with the text editor is shows weird symbols. I also tried using the official aosp a2dp file but nothing. My device is Gionee f103 pro . Any help on how I can edit that file or fix my problem?
