Its a limitation of the bluetooth protocol. Windows and macos implement both A2DP and HFP and switch on the fly when microphone usage is requested by an app. HFP uses a low quality GSM codec so the sound quality will degrade when switching to that profile.
It is possible to have multiple bluetooth profiles active on one device but A2DP and HFP are mutually exclusive due to bandwidth limitations. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/508522 Title: Mic is not available with A2DP Bluetooth profile To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/508522/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
