Are you experiencing delayed audio when using Bluetooth headphones or speakers with Ubuntu 24.04? This complete guide shows you how to fix Bluetooth audio latency issues by optimizing your PipeWire 1.2 configuration.

What Causes Bluetooth Audio Latency in Ubuntu 24.04?

Ubuntu 24.04 uses PipeWire 1.2 as its default audio server, replacing the older PulseAudio system. While PipeWire offers improved performance, some users experience noticeable audio delays with Bluetooth devices.

The main causes include:

• Default zero-latency buffer settings that cause audio stuttering
• Incorrect quantum values for your specific hardware
• Bluetooth codec compatibility issues
• System resource contention under high loads

Prerequisites for This Tutorial

Before beginning, make sure you have:

• Ubuntu 24.04 with PipeWire 1.2 installed (default in this version)
• A Bluetooth audio device that’s already paired and connected
• Basic familiarity with terminal commands
• Administrator (sudo) privileges on your system

Checking Your Current PipeWire Configuration

First, let’s verify your current PipeWire setup and identify your Bluetooth device information.

Open a terminal and run:

# Check if PipeWire is running as your audio server
pactl info | grep "Server Name"

You should see output showing PipeWire is active, similar to:

Server Name: PulseAudio (on PipeWire 1.2.x)

Next, identify your Bluetooth device:

# List all connected audio devices
pactl list short sinks

Then get detailed information about your Bluetooth device:

# Replace DEVICE_NAME with your device from previous command
pactl list sinks | grep -A 20 DEVICE_NAME

Note your Bluetooth device name and port information. You’ll need these values for the next steps.

Step 1: Install Required Packages

First, ensure you have all the necessary PipeWire components installed:

sudo apt update
sudo apt install pipewire-audio-client-libraries libspa-0.2-bluetooth wireplumber

Step 2: Optimize PipeWire Latency Buffer Settings

PipeWire’s default configuration often sets Bluetooth devices with zero latency offset, which can cause audio problems. Let’s fix that:

1. First, get your device details:

# Find your Bluetooth card name and port
pactl list cards | grep -E "Name:|device.description|Active Profile:|Speaker|Headphone"

Look for output similar to:

Name: bluez_card.XX_XX_XX_XX_XX_XX
    device.description = "Bluetooth Speaker"
        Active Profile: a2dp_sink
            speaker-output: Speaker (priority: 0, latency offset: 0 usec, available)

1. Set an appropriate latency buffer using:

# Syntax: pactl set-port-latency-offset CARD_NAME PORT_NAME MICROSECONDS
pactl set-port-latency-offset bluez_card.XX_XX_XX_XX_XX_XX speaker-output 50000

The value 50000 represents 50 milliseconds, which works well for most setups. You may need to experiment with values between 20000-100000 to find the best setting for your device.

Step 3: Adjust PipeWire Quantum Settings

PipeWire’s quantum settings control buffer sizes and can significantly impact latency. For Bluetooth audio devices, the default settings are often too aggressive.

1. Check your current quantum value:

pw-top

1. Experiment with different quantum values while playing audio:

# Try increasing values (1024, 2048, 4096) until audio smooths out
pw-metadata -n settings 0 clock.force-quantum 2048

1. Once you find a good value, make it permanent by creating a configuration file:

mkdir -p ~/.config/pipewire/pipewire.conf.d/

1. Create the configuration file:

nano ~/.config/pipewire/pipewire.conf.d/bluetooth-latency.conf

1. Add the following content (adjust the quantum value based on your testing):

context.properties = {
  default.clock.quantum = 2048
  default.clock.min-quantum = 2048
  default.clock.max-quantum = 8192
}

Save and close the file.

Step 4: Optimize Bluetooth Codec Settings

PipeWire supports various Bluetooth codecs, and selecting the right one can reduce latency:

1. Create a WirePlumber configuration directory:

mkdir -p ~/.config/wireplumber/bluetooth.lua.d/

1. Create a codec configuration file:

nano ~/.config/wireplumber/bluetooth.lua.d/51-bluez-config.lua

1. Add the following content:

bluez_monitor.properties = {
  ["bluez5.enable-sbc-xq"] = true,
  ["bluez5.enable-msbc"] = true,
  ["bluez5.enable-hw-volume"] = true,
  ["bluez5.codecs"] = {
    "ldac",
    "aptx_hd",
    "aptx",
    "aac",
    "sbc_xq",
    "sbc"
  },
}

This configuration prioritizes higher-quality, lower-latency codecs when available.

Step 5: Restart PipeWire Services

Apply all your changes by restarting the PipeWire services:

systemctl --user restart pipewire pipewire-pulse wireplumber

Step 6: Set Real-Time Priority (Optional)

For further latency improvements, you can give PipeWire real-time priority:

1. Create a group for audio processing:

sudo groupadd -r pipewire
sudo usermod -aG pipewire $USER

1. Add resource limits for the pipewire group:

sudo nano /etc/security/limits.d/99-pipewire.conf

1. Add the following content:

@pipewire - rtprio 95
@pipewire - memlock unlimited
@pipewire - nice -19

1. Log out and log back in for the group changes to take effect.

Testing and Fine-tuning

After applying these changes, test your Bluetooth audio with various applications. Pay attention to:

• Audio start delay
• Sync between video and audio
• Stuttering or dropouts during playback

If you still experience issues, try:

1. Further adjusting the latency buffer (step 2) with values between 20000-100000
2. Testing different quantum values (step 3)
3. Checking Bluetooth signal strength and interference
4. Updating your Bluetooth device’s firmware if possible

Troubleshooting Common Issues

Audio Stuttering Under Load

If audio stutters when your system is under heavy load:

# Try a larger quantum value
pw-metadata -n settings 0 clock.force-quantum 4096

Update your configuration file accordingly.

Audio Delay When Starting Playback

If you notice a delay when audio first starts:

# Reduce resampler quality for faster processing
mkdir -p ~/.config/pipewire/pipewire.conf.d/
echo 'context.properties = { default.clock.rate = 48000 }' > ~/.config/pipewire/pipewire.conf.d/sample-rate.conf

Bluetooth Disconnects Frequently

If your Bluetooth device disconnects:

# Enable lingering for PipeWire services
loginctl enable-linger $USER

Create a configuration file to prevent Bluetooth disconnects after idle time:

sudo mkdir -p /etc/wireplumber/bluetooth.lua.d/

sudo nano /etc/wireplumber/bluetooth.lua.d/50-bluez-config.lua

Add:

bluez_monitor.properties = {
  ["bluez5.enable-sbc-xq"] = true,
  ["bluez5.reconnect-profiles"] = true
}

Conclusion

By optimizing your PipeWire 1.2 configuration in Ubuntu 24.04, you can significantly reduce Bluetooth audio latency. Finding the right buffer and quantum settings for your specific hardware is key to achieving the best balance between responsive audio and stability.

Remember that different Bluetooth devices may require different optimal settings. Don’t hesitate to experiment with various values to find what works best for your specific setup.

Not getting sound from your Bluetooth headset? Read the following steps to troubleshoot the issue:

A similar kind of incident happened to me when I tried to pair my Bluetooth headset with my laptop.

After purchasing a new headset, I decided to test the audio quality. If it’s not as per my expectations, then I’ll return it, so I opened the box and tried to connect my system with the device.

Once the Bluetooth is connected, I try to play a song, but unfortunately, sound is coming out through the laptop speaker.

At first, I thought there may be some problem with pairing due to the fact that I’m not able to get sound, but as I can see, Bluetooth is already paired with the system.

If you have the same scenario or something a bit different, then try to follow this short guide to fix the issue.

There can be multiple scenarios for the above error, and due to that, I cannot vouch for which method will work in your case, so I suggest trying out all the solutions mentioned below. 

Method 1: Install PulseAudio Bluetooth Module

The first and foremost thing we will try is to install pulseaudio-module-bluetooth, and after that, you need to kill the pulseaudio server and restart the pulseaudio service.

To do so, run the following command in the given sequence:

$ sudo apt install pulseaudio-module-bluetooth

$ pulseaudio -k
$ pulseaudio --start

I hope the problem is resolved; if not, jump to the next method.

Method 2: Select Default Output Source

In the next step, we will make sure to check the output source.

If the output source is not properly configured, then you might face the problem of no sound from the Bluetooth source.

To verify the source information, I would tell you to go to your system settings, go to the sound or audio option, and check the output source.

If the output source is different than expected, then click on the drop-down option and change the source.

For more information about this step, check out this article for the complete step.

And anyway, if the problem still persists, you can move on to the next method.

Method 3: Install Pavucontrol

The next thing you can do to solve this issue is to install Pavucontrol, which allows you to manage audio devices on your system and also helps you select the appropriate input and output devices.

To install Pavucontrol, run the following command on your system according to your distribution’s package manager:

• Install Pavucontrol on Debian and Ubuntu

$ sudo apt install pavucontrol

• Install Pavucontrol on Centos/RHEL

$ sudo yum install pavucontrol

• Install Pavucontrol on Fedora/Centos

$ sudo dnf install pavucontrol

• Install Pavucontrol on Arch Linux and Manjaro

$ sudo pacman -Sy pavucontrol

Once you have installed Pavucontrol, play some audio or video content in the background and run the following command on the terminal to run Pavucontrol:

$ pavucontrol

Now switch tabs to “Output Devices”.

Here you will find all the output sources; select the appropriate one according to your device, as shown below.

Next, check the right option “Set as fallback” and click on the port drop-down options and select “Headphone (plugged in)”.

I think now you may be able to hear audio from your Bluetooth device.

Method 4: Install PipeWire and Replace PulseAudio

If your system is still using PulseAudio, then it’s better to replace the audio server with PipeWire. To know how to replace PulseAudio with PipeWire, check out the following article according to your distribution:

Debian: https://trendoceans.com/install-pipewire-on-debian-11/
Ubuntu: https://trendoceans.com/enable-pipewire-and-disable-pulseaudio-in-ubuntu/

Wrap up

That’s all for now!

I hope you are able to resolve your problem with one of the above methods. If yes, then let me know in the comment section which method worked in your case.

There is one more resource from the ArchLinux Wiki that you can use to fix the issue.
