On Dell Inspiron 3593 running Ubuntu 20.04, Bluetooth Headset Vipex VX-BH001 works in A2DP, but not in HSP/HFP. (So it cannot be used as a microphone.)
Same headset works correctly on an older Dell Latitude under both 20.04 and 18.04, and works on the same laptop when using an external USB bluetooth adapter, so I conclude the issue is probably with the iwlwifi driver or firmware.
The bluetooth headset pairs okay, but in sound settings if I switch configuration to "Headset Head Unit (HSP/HFP)", then the "test" dialog under "output" will not play sound, and the "input" panel does not show any incoming audio.
I tried upgrading to -proposed kernel and installing updated firmware in /lib/firmware, but without improvement.
I also note that 'modinfo iwlwifi' on my laptop lists support for firmware up to iwlwifi-Qu-c0-hr-b0-52.ucode, but linux-firmware.git has newer firmware published: iwlwifi-Qu-c0-jf-b0-55.ucode
