Bluetooth headset connects to bluetooth audio transmitter adapter, but no sound

My bluetooth headset connects successfully to my bluetooth audio transmitter adapter and is listed as audio device in the pulseaudio list as UACDemoV1.0 Analog Stereo. However, there is no sound output.

On windows 10, I have no problems by using this dongle and this headset

My bluetooth audio transmitter adapter: Jieli Technology PC-T7.
My headset: Epos H3 Hybrid

I have installed pulseaudio-modules-bt and libldac

Here is the output of pactl list

Ok, solved my issue. For some reason, the PCM was muted in alsa.

Typing
amixer -c3 set 'PCM',0 100%,100%

fixed it and I got sound. Additionally I changed from pulseaudio-modules-bt to pulseaudio-bluetooth.
