This is not a duplicate bug, bug 508522 covers automatic switching of profiles since a2dp and hsp/hfp are mutually exclusive, there can not be two profiles active at the same time.
The true bug here is the bad voice quality, which is caused by a lack of codec negotiation. This is why bluetooth headsets will sound better connected to a random (> 4.4) android phone, which will negotiate mSBC, also known as "wide band speech", supported since HFP 1.6. This can be mistaken for "a2dp and microphone active at the same time", even though it is still a monaural configuration not related to a2dp, because it sounds so much better. The HSP/HFP mode is using the CVSD codec which sounds like a bad gsm call, there have been attempts to merge proper codec negotiaton, but the work has stalled for some reason - see the related thread at https://www.spinics.net/lists/pulse-audio/msg29370.html and the stale patchset at https://patchwork.freedesktop.org/series/30716/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1828393 Title: Unable to use bluetooth headset with mic and a2dp audio Status in pulseaudio package in Ubuntu: Confirmed Bug description: Every device supports high fidelity audio while using headset with mic. This needs to enable two profiles at once: headset_head_unit and a2dp_sink. Right now this is impossible and I need to switch between profiles when listening to music and joining a call. In any case, the sound quality of HSP/HFP used in the headset_head_unit profile is horrible to have a call.
