I sit in the offline meeting and joining parallel the same meeting per Skype for Business, because I need to present for online participants. Despite of speakers being muted, my MacBook Pro (2018) plays a very loud join sound and then the huge noise is coming due to sound feedback loop (presenter connected the sound station in the meeting room with sensitive microphones). I muted again the speaker and all was silent again.
I tried again joining the Skype meeting afterwards and confirmed that Skype for Business really un-mutes my speaker, when I join the call.
I never experienced such problem with Windows - if the mic or speaker was muted during the joining of the presentation, they also remained muted.
I'd like to have the same behavior as by Windows - if I muted the speaker, it shall remain so.
I searched Google, but I didn't find anything. May be anybody knows, if it is possible to keep speakers muted when I join the Skype for Business meeting?
I have the latest macOS Mojave 10.14.3 and use Skype for Business 16.24.191.
