somedays ago, I use bluetoothctl connect my audio device, and use pactl lisl sinks short list bluetooth device successfully. This is my note somedays ago.

nvidia@nvidia:~$ pactl list sinks short
45      alsa_output.platform-88090b0000.hda.hdmi-stereo PipeWire        s32le 2ch 48000Hz       SUSPENDED
46      alsa_output.platform-sound.analog-stereo        PipeWire        s24-32le 2ch 48000Hz    IDLE
183     bluez_output.AA_9B_B8_7E_58_3E.1        PipeWire        s16le 1ch 16000Hz       RUNNING

but now, I cant see the bluez_output.AA_9B_B8_7E_58_3E.1 device? maybe reboot cause this problem， I dont know why?

“I’m quite certain that my Bluetooth speaker is connected, because when I run the disconnect and connect commands, the bluetooth speaker plays the ‘device disconnected’ and ‘device connected’ voice prompts.”

Check the status of the Bluetooth radio

rfkill list

If it says Soft blocked: yes, run

sudo rfkill unblock bluetooth

Then restart bluetooth service

sudo systemctl restart bluetooth

Run

pactl list cards short

If you see bluez_card.AA_9B_B8_7E_58_3E there, but no sink, manually set the profile:

pactl set-card-profile bluez_card.AA_9B_B8_7E_58_3E a2dp-sink

I test it , but not work
