Nov 13, 2020 @ 11:57pm. ALSA provides the low-level hardware sink with no default mixing. Pulse uses ALSA as a backend while providing a mixed sink for applications in a multitasking environment. Most of the 'mushiness' from Pulse comes from the default fast-and-dirty mixing and resampling methods it uses.

Alsa or PulseAudio? : voidlinux

A suggestion: do not start pulseaudio as a daemon or a service. If it is installed, programs that use it, like pavucontrol or firefox, will start it automatically, using dbus I think. Most programs, like firefox, will only use alsa as a fallback in case pulseaudio is not available.

dmix has the same kind of effect within the ALSA library, but PulseAudio gives you more flexibility, and someone else said that in his experience it runs faster and gives less latency. PulseAudio provides an ALSA plugin, so you can do, for example, (with the right stanza in .asoundrc) aplay -D pulse song.wav

Alsa dmix high cpu usage | Linux.org

https://www.linux.org/threads/alsa-dmix-high-cpu-usage.22918/

So I decided to skip pulseaudio and only use Alsa with Dmix, and the sound works great! No problem at all with the sound. Added ”autospawn = no” to /etc/pulse/client.conf, but I notice some higher cpu usage. I have set sample rate with Alsa to 44100. mpg123 uses 30%, and mplayer 80%. With pulseaudio mpg123 it is 1-2% and mplayer 20-30%.

play multiple sound streams on ALSA dmix - LinuxQuestions.org

I'm having trouble getting ALSA to play multiple sound streams (multiple sounds at once). My code is running on an embedded ARM board using a AC97 sound. It will only play one without any mixing, I have to use pure ALSA as higher sound mixers are a nightmare to cross compile for ARM. works fine. So I tried dmix with.
