Comment 19 for bug 2051895

verification on mantic:

Install UBUNTU 23.10 on the Lenovo Thinkpad X1C 12Gen, and enable the mantic-propsed from "Software & Updates". By default, the pulseaudio is not installed, in the manic, the pipewire replaced the pulseaudio in the audio stack. I installed the pulseaudio manually by running 'sudo apt-get update; sudo apt install pulseaudio', the pulseaudio 1:16.1+dfsg1-2ubuntu4 was installed and pipewire-alsa was removed. Increased the priority to 510 for all packages in proposed by adding proposed-updates in the /etc/apt/preferences.d/, the upgraded the pulesaudio to 1:16.1+dfsg1-2ubuntu4.1:

non-audio bt devices (pairing, reconnect, functional test all pass):
 - piano2 (bt keyboard)
 - bluetooth laser travel mouse (logic bt mouse)

audio bt devices (pairing, reconect, set a2dp and hsp/hfp, playback and capture, all test pass)
 - xt99 (lenovo thinkplus bt headset)
 - plt_btgo2 (bt headset)
 - soaiy s18 (bt sound bar)
 - i7mini (bt headset)

Verification done for mantic.
