ALSA, PulseAudio or PipeWire – What Should Linux Audio Use?
Linux audio can be confusing because ALSA, PulseAudio and PipeWire perform different but sometimes overlapping jobs.
ALSA communicates with the audio hardware and provides the low-level drivers. PulseAudio was commonly placed above ALSA to manage applications, volume controls and switching between sound devices.
PipeWire is now replacing PulseAudio on many Linux systems. It can manage normal desktop audio, Bluetooth devices and professional low-latency audio through one system. This makes it particularly useful on a Raspberry Pi music player that needs to switch between a DAC, HDMI and Bluetooth headphones.
Direct ALSA output may still be preferable for a simple dedicated music player because it has fewer layers. However, PipeWire provides much more flexibility when several applications or output devices are involved.
Have you moved to PipeWire, or do you still find direct ALSA or PulseAudio more reliable for your setup?
