Hi ! I don't have the exact same problem given in the title.
I am on an Ubuntu 18.04 laptop for work and use BOSE QC 35 II headphones and more recently Sony WF-1000XM3s earbuds. I can switch from one profile to another, A2DP Sink to HSP/HFP. However, with the A2DP profile I have stereo sound (good) but no microphone. With the HSP/HFP profile, I have mono sound (not good) with crackling but with the microphone working. As soon as I choose my headphones/earphones in the inputs, it automatically switches the sound profile (output) of my device to HSP/HFP. If I select the A2DP profile again, it changes the microphone input to the laptop one or a usb dock (when I use one with microphone input), which is not practical if I want to take a few steps away from the laptop. I read here and there that the A2DP was only mono-directional which explains the lack of support for the microphone. I hope that in 2021 (it's dead for 2020), someone will find a new way to make Bluetooth devices work with a microphone on linux in stereo with good sound quality. In my opinion, the HSP/HFP profile is no longer made for the years 2020+. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1576559 Title: Refused to switch profile to headset_head_unit: Not connected Status in PulseAudio: Unknown Status in pulseaudio package in Ubuntu: Confirmed Bug description: I'm trying to connect a bluetooth-speaker-with-microphone (Mi Bluetooth Speaker) to Ubuntu. It works well as an A2DP sync, but can't use it as a headset with microphone. The device doesn't list in the "Input Devices" by default, and using the sound settings to change the profile of the device to HSP/HFP results in this log message: W: [pulseaudio] module-bluez5-device.c: Refused to switch profile to headset_head_unit: Not connected I'm running Ubuntu 16.04 LTS.
