I think they are working since the alerts are always the same volume no matter if I had to turn up the volume on a phone call or not.It should send to media stream when force speaker and auto stream selection are disabled. Are your alert and auto mute volume controls having no effect, too?
It's just the deet deet of the bogey lock tone that's super loud because it's going to call volume so it's getting cranked up really loud. I have it set to 30% under K and Ka under audio settings but it doesn't change it.
I turned media stream and force speaker off while it wasn't connected then after I left work I made a call and bogey lock tone still got really loud after I hung up.
