Pipewire vs PulseAudio, general question
Pipewire vs PulseAudio, general question
Pipewire is the new hotness. I’ve read comments from various audio engineers and programmers that pipewire “gets it right”.
Pipewire came out in 2017, pulseaudio in 2004.

After application transfers the data in the memory areas, then it must be acknowledged the end of transfer via snd_pcm_mmap_commit() function to allow the ALSA library update the pointers to ring buffer. This kind of communication is also called “zero-copy”, because the device does not require to copy the samples from application to another place in system memory.
When you tell RTFM expect to see manual stating opposite of your point.
Not direct enough? It literally says it will send your buffer to soundcard without creating any additional buffers.
Other people under this post complain of ALSA being too direct.
