[ROM][11.0] crDroid 7.x for A5/A7 2017

Jan 20, 2018
Hi there,

Just one question I have an crackling sound issue on WIFI calls especaially with my SIP Client APP with it I use my Smartphone as a landline phone, a bit crackling on telegram Wifi calls and the weird thing is Skype calls working fine. Well the most important thing is the SIP client telegram isnt necessary.

I have it on Android 10 and 11 lineageos and based Roms like yours. I tryed to fix it to only flash without Gapps and deactivated each speech input, clean dalvik cache but nothing works. Your other Rom "Rise-Q-v2.1" working fine and it is really nice, thanks for that.

It is probarbly a random Lineageos 17.1 and 18.1 issue because I read some user on other devices has the issue of crackling sound in different ways. Could it possible to fix it via installing Viper4Arise or repair Audio permissions?

Edit: Found a solution to reduce the problem a bit, install any tweaking kernel app like adiutor and set the TCP Congestion to "cubic" this helped in my case on all Lineage, CRdroid and based Roms. But not at all sometimes crackling come back for just a moment.

Hi great rom, thanks for the effort you put into it. One question, can I flash it on a Galaxy A6 2018? It has Exynos 7870 instead of 7880 and Mali-T830MP1 instead of Mali-T830MP3. Thanks.
