Sennheiser HD 450BT microphone not working

Hi,
I'm having some trouble to get the headset microphone working: despite the device is correctly connected throw bluetooth and perfectly working for output audio, no input seems to be detected.
I'm actually using pipewire (installed after many attempts with pulseaudio), and the active profile is Headset Head Unit (HSP/HFP, codec mSBC).
This is the output for arecord --list-pmc:

null
    Discard all samples (playback) or generate zero samples (capture)
lavrate
    Rate Converter Plugin Using Libav/FFmpeg Library
samplerate
    Rate Converter Plugin Using Samplerate Library

jack
    JACK Audio Connection Kit

    Open Sound System
pipewire
    PipeWire Sound Server
pulse
    PulseAudio Sound Server
speex
    Plugin using Speex DSP (resample, agc, denoise, echo, dereverb)
upmix
    Plugin for channel upmix (4,6,8)
vdownmix
    Plugin for channel downmix (stereo) with a simple spacialization

    HDA Intel PCH, ALC3234 Analog
    Front output / input
usbstream:CARD=PCH
    HDA Intel PCH
    USB Stream Output

and this is the output for arecord -l

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3234 Analog [ALC3234 Analog]
  Subdevices: 0/1

What may I be missing?
Thanks in advance for any help!

Re: Sennheiser HD 450BT microphone not working

ALSA/arecord is irrelevant for bluetooth audio. Post

Re: Sennheiser HD 450BT microphone not working

General setup looks ok but you aren't recording anything actively here and all the plasma volume applet stuff delutes things a bit, try to record something and repost the last two outputs. FWIW try switching profiles to e.g. headset-head-unit and cehck whether that one works, make sure the headset isn't muted on the headset itself incidentally.

Re: Sennheiser HD 450BT microphone not working

I have problem switching profiles, especially headset-head-unit falls back to headset-head-unit-msbc (or CVSD).

I also noticed that there are a lot of this logs in the journal:

kernel: Bluetooth: hci0: corrupted SCO packet

And also:

wireplumber[1339]: sbc_decode failed: -3

There is  pactl list sources after recording
