[pulseaudio-discuss] Bluetooth headset HSP/HFP sound not working but microphone is

Dear pulseaudio,

I've, for year's, been happily working with pulseaudio on ubuntu. 
Recently an issue appeared with the combination with my headset Sony 
WH-H900N. It used to work in the following two profiles:

 1. HSP/HFP mode with microphone & sound
 2. A2DP for high quality sound only (I combine this with an LDAC profile)

I'm not sure since when, but I'm profile 1 is not working any more. The 
microphone is, but the sound does not come through. I do hear more 
static when it switches to the HSP/HFP profile but nothing that I play 
gets to sound from the headset. The exact problem, and the related issue 
search is documented as askubuntu 
Do you know what is wrong and how to fix it? Did anything regarding 
HSP/HFP change on the pulseaudio side. Or could you help me getting to 
the exact cause of the problem?

Kind Regards,
Bram Lagerweij
