Manage audio devices, volume, and the sound server
Most current distros (Fedora, Ubuntu 22.10+, recent Arch installs) now default to PipeWire as the audio (and video) server, usually with the pipewire-pulse compatibility layer so PulseAudio-based apps keep working unmodified; older systems still run PulseAudio directly.
What you should know
- GUI volume/device control is the same either way — the speaker icon in the system tray, or Settings > Sound in GNOME/KDE.
- Check which sound server is active with `pactl info` — the "Server Name" line reports "PulseAudio (on PipeWire ...)" if PipeWire is running the compatibility layer.
- Install/switch on Ubuntu/Debian: `sudo apt install pipewire-audio pipewire-pulse`; Fedora ships PipeWire by default; Arch: `sudo pacman -S pipewire pipewire-pulse wireplumber`.
- `pavucontrol` (PulseAudio Volume Control) works against both PipeWire and PulseAudio and is the most reliable place to fix per-app output routing and input levels.
Why it matters
Audio routing is one of the more fragmented parts of the Linux desktop stack — knowing whether you're on PipeWire or PulseAudio (and that WirePlumber is PipeWire's session manager) saves a lot of time chasing fixes written for the wrong stack.
Best practices
- Use `pavucontrol` for per-application volume and device routing rather than hunting through each app's own settings.
- If migrating an older system to PipeWire, remove `pulseaudio` and `pulseaudio-utils` packages rather than running both stacks side by side.
- For pro-audio/low-latency work, PipeWire's JACK compatibility layer (`pipewire-jack`) usually removes the need for a separate JACK install.
Common problems and fixes
- No sound after a fresh install or after suspending
- Restart the audio stack with `systemctl --user restart pipewire pipewire-pulse wireplumber` (or `pulseaudio -k` on PulseAudio systems, which auto-restarts it).
- Bluetooth headphones connect but no audio
- Confirm the Bluetooth A2DP profile is selected in `pavucontrol`'s Configuration tab, and that `pipewire-pulse`/`pulseaudio-module-bluetooth` is installed.
Tips and tricks
- `wpctl status` gives a quick tree view of every PipeWire audio input/output and which app is bound to which device.
Frequently asked questions
Should I switch from PulseAudio to PipeWire manually?
Only if your distro hasn't already — most mainstream distros migrated by default in 2022–2023. If audio works fine today, there's no urgent need to switch it yourself.

- Display & Graphics DriversGraphics driver setup is the single biggest source of Linux desktop friction, especially on NVIDIA hardware — the open-source nouveau driver loads by default but the proprietary NVIDIA driver is usually what you actually want for full performance, hardware video decode, and multi-monitor/mixed-refresh-rate support.
- Desktop Environment CustomizationDesktop environments (GNOME, KDE Plasma, XFCE, Cinnamon, etc.) each have their own settings apps and customization ecosystem — GNOME leans on extensions and GNOME Tweaks for anything beyond the basics, while KDE Plasma exposes most customization directly in System Settings.
