Alert user when System Mixer is supported but turned off under settings
Hi, thanks for building this wonderful app, it's a really great project!
I've recently come across something strange: whenever I find a new update and update Call Recorder via F-Droid, the "System Mixer In-call recording" setting gets disabled under settings and that is causing an issue where the opponent's voice is inaudible partially/completely. Since my device is rooted, I always make sure the System Mixer option is enabled under Settings but for some reason it gets auto-disabled whenever I update the app.
I've skimmed through the code with my limited understanding to debug it, but no dice so far, unfortunately. Although, temporarily, I added a alert message on launching MainActivity that shows when the System Mixer is supported (rooted device) but is disabled. One of the reasons this is a serious issue to me is that with the System Mixer turned off all the calls recorded thereafter have the same recurring issue (missing opponent voice).
If you can fix the issue, great :), else please leave me a few pointers to analyse and fix the issue.
