I have a similar problem.

We’ve used three (me, my wife and our friend) s7 with clean install of FloydQ 8.0, safety patch and CronosKernell v.8.1 for several weeks now. Since the beginning we faced the problem of muted microphone while phone calls after using the phone for a while after the restart. We started to investigate the problem as we have to restart at least once a day. So that’s what we found:

• The problem occurs ONLY while VoLTE phone calls – we need VoLTE all the time so this is a real problem for us.
• Both sides (caller and receiver) must use VoLTE. If either phone does not use volte, the problem does not occur. Suprisingly even when the receiver switches VoLTE off while the caller still has it on, caller’s phone microphone starts to work normally.
• when change into BT device while phone call, everything is fine - BT device’s microphone works ok. When switching BT device off, phone’s microphone (or the loudspeaker) is muted.
• only restarting the phone fixes the problem, but not for long :(
• to quickly trigger an error, just turn on the loudspeaker while making a call. After this, the microphone usually mutes. There are definitely other sequences that cause this (while using the phone all of a sudden I realize that nobody can hear me when I call), but I haven't been able to diagnose them yet. It seems that turning the speaker on or connecting BT devices affects this.
