🎯 Understanding Linux Audio

Linux Audio Stack

Linux audio uses multiple layers:

  1. ALSA (Advanced Linux Sound Architecture)

    • Low-level audio driver
    • Direct communication with sound hardware
    • Kernel level (closest to hardware)

  2. PulseAudio or PipeWire

    • Sound server (audio manager)
    • Manages audio streams, mixing, routing
    • User level (application interface)

  3. Applications

    • Programs you use (browser, music player, etc.)
    • Produces audio
    • Application level

How it works:

Application → PulseAudio/PipeWire → ALSA → Hardware

PulseAudio vs PipeWire

PulseAudio:

  • Traditional sound server
  • Mature, stable, widely used
  • Audio mixing, routing, network audio
  • Default on most Linux distributions

PipeWire:

  • Modern replacement for PulseAudio
  • Better low latency, video support, screen sharing
  • Default on some newer distributions

Which to use:

  • PulseAudio: Stable, works everywhere, good for most users
  • PipeWire: Better for low latency, modern features, future-proof

🔊 PulseAudio Configuration

Install PulseAudio

Arch Linux / CachyOS:

# Install PulseAudio
sudo pacman -S pulseaudio pulseaudio-alsa pavucontrol

# For Bluetooth
sudo pacman -S pulseaudio-bluetooth

Debian/Ubuntu:

sudo apt install pulseaudio pavucontrol

Fedora:

sudo dnf install pulseaudio pavucontrol

Enable PulseAudio

Start PulseAudio:

# Enable user service
systemctl --user enable pulseaudio
systemctl --user start pulseaudio

# Check status
systemctl --user status pulseaudio

PulseAudio Control

GUI control:

# Open PulseAudio Volume Control
pavucontrol

🎵 PipeWire Configuration

Install PipeWire

Arch Linux / CachyOS:

# Install PipeWire
sudo pacman -S pipewire pipewire-pulse pipewire-alsa

# For JACK
sudo pacman -S pipewire-jack

Debian/Ubuntu:

sudo apt install pipewire pipewire-pulse

Fedora:

sudo dnf install pipewire pipewire-pulseaudio

Enable PipeWire

Start PipeWire:

# Enable services
systemctl --user enable pipewire pipewire-pulse
systemctl --user start pipewire pipewire-pulse

# Check status
systemctl --user status pipewire

🎚️ ALSA Configuration

ALSA Basics

ALSA is the low-level audio driver.

Check ALSA:

# List sound cards
aplay -l

# Check ALSA mixer
alsamixer

ALSA Configuration

Edit config:

# Edit ALSA config
sudo vim /etc/asound.conf

🎧 Audio Device Management

List Audio Devices

Check devices:

# PulseAudio
pactl list sinks short
pactl list sources short

# PipeWire
pactl list sinks short
pactl list sources short

Set Default Device

Set default:

# Set default sink
pactl set-default-sink sink-name

# Set default source
pactl set-default-source source-name

📻 Bluetooth Audio

Setup Bluetooth Audio

PulseAudio:

# Install Bluetooth support
sudo pacman -S pulseaudio-bluetooth

# Restart PulseAudio
pulseaudio -k && pulseaudio --start

PipeWire:

# PipeWire includes Bluetooth support
# No additional package needed

🎤 Microphone Configuration

Test Microphone

Record test:

# Install tools
sudo pacman -S alsa-utils

# Record
arecord -d 5 test.wav

# Playback
aplay test.wav

Configure Microphone

Set default:

# Set default source
pactl set-default-source source-name

# Increase volume
pactl set-source-volume source-name 100%

🔧 Troubleshooting

No Sound

Check audio:

# Check if muted
pactl list sinks | grep -i mute

# Unmute
pactl set-sink-mute sink-name false

# Increase volume
pactl set-sink-volume sink-name 100%

Audio Not Working

Check services:

# Check PulseAudio
systemctl --user status pulseaudio

# Check PipeWire
systemctl --user status pipewire

# Restart
systemctl --user restart pulseaudio

Permission Issues

Fix permissions:

# Add to audio group
sudo usermod -aG audio username

# Log out and back in
