# **Connecting Sony WH-1000XM4 to Ubuntu 22.04 (Jammy)**

This guide will help you connect your Sony WH-1000XM4 headset to Ubuntu 22.04 using Bluetooth. Once connected, you'll be able to listen to music and use the microphone on apps like Microsoft Teams.

## **1. Connect to Bluetooth Headset**

### **Steps**:

1. Open a terminal and launch `bluetoothctl`:
   ```bash
   bluetoothctl
   ```

2. Initialize the agent and set it as the default:
   ```
   agent on
   default-agent
   ```

3. Scan for Bluetooth devices:
   ```
   scan on
   ```
   Look for the MAC address of your Sony WH-1000XM4 headset.

4. Stop the scanning process:
   ```
   scan off
   ```

5. Pair, trust, and connect to the headset using its MAC address:
   ```
   pair XX:XX:XX:XX:XX:XX
   trust XX:XX:XX:XX:XX:XX
   connect XX:XX:XX:XX:XX:XX
   ```
   (Replace `XX:XX:XX:XX:XX:XX` with the MAC address of your headset.)

6. Exit `bluetoothctl`:
   ```
   exit
   ```

## **2. Enable PipeWire for Better Audio Handling**

Ubuntu 22.04 partially uses PipeWire by default. To fully utilize it for audio and Bluetooth, follow these steps:

### **Installation**:

1. Install and start WirePlumber:
   ```bash
   sudo apt install pipewire-media-session- wireplumber
   systemctl --user --now enable wireplumber.service
   ```

### **Configuration**:

- **For ALSA**:
  ```bash
  sudo apt install pipewire-audio-client-libraries
  sudo cp /usr/share/doc/pipewire/examples/alsa.conf.d/99-pipewire-default.conf /etc/alsa/conf.d/
  ```

- **For Bluetooth**:
  ```bash
  sudo apt install libldacbt-{abr,enc}2 libspa-0.2-bluetooth pulseaudio-module-bluetooth-
  ```

### **Validation**:

After rebooting your system, you can check if PipeWire is active by running:
```bash
LANG=C pactl info | grep '^Server Name'
```

### Switch Audio Profile using CLI
