Cannot select HSP/HFP Profile for my headsets

Registered Member
I am working on a Lenovo X230 and I have a Logitech H800 headset which can be connected via BT and it's own dongle.
The problem is that I cannot use it's microphone on my meetings and it's very important to me to do so.

I run KDE Frameworks 5.64 on Fedora 30 (latest update for both).

My problem:
I cannot activate the HSP/HFP profile for my headset!
According to System Settings --> Multimedia --> Audio and Video --> Backend, I am using Phonon GStreamer backend (version 4.9.0)

From the System Settings --> Multimedia --> Audio Volume --> Advanced, I see the H800 having only the A2DP Sink profile (and the off)
However, it's clear that the headphones can be used with HSP/HFP:

Code: Select all
Card #11
        Name: bluez_card.00_0D_44_31_DF_CB
        Driver: module-bluez5-device.c
        Owner Module: 42
                device.description = "H800 Logitech Headset"
                device.api = "bluez"
                device.class = "sound"
                device.bus = "bluetooth"
                device.form_factor = "headset"
                bluez.alias = "H800 Logitech Headset"
                device.icon_name = "audio-headset-bluetooth"
                device.intended_roles = "phone"
                headset_head_unit: Headset Head Unit (HSP/HFP) (sinks: 1, sources: 1, priority: 30, available: no)
                a2dp_sink: High Fidelity Playback (A2DP Sink) (sinks: 1, sources: 0, priority: 40, available: yes)
                off: Off (sinks: 0, sources: 0, priority: 0, available: yes)

However, I cannot even change it from the CLI:

Code: Select all
pacmd set-card-profile 11 headset_head_unit
Failed to set card profile to 'headset_head_unit'.

And from the logs:

W: [pulseaudio] module-bluez5-device.c: Refused to switch profile to headset_head_unit: Not connected

The headphone works just fine on my Android phone & Tablet so, obviously I need to change something somewhere in my KDE.

Any help would be appreciated.

I think this is actually a bluetooth issue, moving the post.

Currently running Kubuntu 20.04, Plasma 5.18.5, Frameworks 5.68.0, Qt 5.12.8, kernel 5.4.0-40
FWIW: it is always useful to state the exact Plasma version and distribution when asking questions in this forum, makes it easier for us to help ...
