Shows a device that calls itself "Lasmex LBT10" and has MAC address "00:1D:43:6D:03:26". Now make sure that your headset is in pairing mode. To be greeted by its internal command prompt. For troubleshooting and more detailed explanations of bluetoothctl see the Bluetooth article. Now we can use the bluetoothctl command line utility to pair and connect. Note: Before continuing, ensure that the bluetooth device is not blocked by rfkill. For more information, see PipeWire#Bluetooth devices. Use pavucontrol or your desktop environment's settings for configuration. The daemon will be started automatically as a user service.
Install pipewire-pulse (which replaces pulseaudio and pulseaudio-bluetooth). It includes out-of-the-box support for A2DP sink profiles using SBC/SBC-XQ, AptX, LDAC or AAC codecs, and HFP/HSP. PipeWire acts as a drop-in replacement for PulseAudio and offers an easy way to set up Bluetooth headsets.

When a client application calls the IAudioEndpointVolume interface in a configuration where there is an amplifier and a physical volume control present, the audio driver exposes a KSNODETYPE_VOLUME node in the topology filter. If Bluetooth or USB audio is present, their volume controls will be controlled separately. The IAudioEndpointVolume interface represents the volume controls on the audio stream to or from an audio endpoint device. The two paths are shown here for illustrative purposes. On a typical PC, only one of these data paths will be present, since there will typically be one set of audio components in the computer. If the audio driver does not indicate that it supports KSPROPERTY_AUDIO_VOLUMELEVEL, the Windows audio engine creates a software volume control APO. If an amplifier is present, the driver advertises, KSPROPERTY_AUDIO_VOLUMELEVEL. One when an amplifier is present and one when the Windows APO software volume control is used.
The diagram shows two separate audio data paths. The following diagram shows a simplified representation of the Windows software volume support. In Windows Vista and later, software volume support is provided for audio hardware that does not include and amplifier with an associated physical volume control.
