What is the relation between ALSA and PulseAudio sound ...
https://askubuntu.com/questions/581128/what-is-the-relation-between-alsa-and-pulseaudio-sound-architecture
ALSA is unable by itself to be used by multiple applications, so PulseAudio provides this functionality among others. Summarized: ALSA - dealing with the hardware, basically owning it. PulseAudio - a software proxy providing additional featues (mixing, equalizer) between your application and the ALSA/OSS subsystem.
Pulse Audio vs ALSA vs audio server vs audio device driver ...
https://unix.stackexchange.com/questions/631746/pulse-audio-vs-alsa-vs-audio-server-vs-audio-device-driver
ALSA contains the actual device drivers (in the kernel source), and a library to access those drivers. You use sound perfectly fine with just ALSA alone. PulseAudio implements an additional audio routing level on top of ALSA, including volumes and conversions. Most distros use the PulseAudio + ALSA combo as the default.
linux - ALSA vs PulseAudio - Latency Concerns - Stack …

Additionally, it's to my understanding that ALSA is tied to Linux, but PulseAudio just acts as an abstraction layer on top of ALSA, and can work on other platforms. My conclusion is that ALSA would provide lower audio latency on most Linux systems, while my colleague contends that PulseAudio provides better (shorter) latency regardless.

On the same day, I set up BL RC1 and Ubuntu Mate 15.10 Beta2. The aplay -l output was identical for both and yet the sound from Ubuntu Mate worked while BL RC1 audio failed. One suggestion that I got was to change settings in VLC preference to change audio output from PulseAudio to Alsa or direct hardware.

Registered: 2012-09-15 Posts: 27. Alsa/PulseAudio vs OSSv4. Hello all, I'm very happy with my Arch desktop right now, but I've noticed that my ALSA/Pulseaudio setup had high latency (obviously, but the Pidgin bleep has a 4-6 second delay, so one might say _very_ high). I've done some reading, notably:
[SOLVED] what difference between pulseaudio, alsa and …

2. Alsa 3. PulseAudio (Youngest) Alsa was started because people were workaholic and felt oss was no use. Ditto PulseAudio because the other two were no use. Personally, I find pulseaudio is no use. Suffer whatever your distro provides and learn it well enough to get sound through. That will be alsa or pulseaudio.
Pulseaudio or Alsa : archlinux - reddit
https://www.reddit.com/r/archlinux/comments/i0zkz/pulseaudio_or_alsa/
PulseAudio was fun: it used 48 kHz (since it's what my card used), which Alsa then downsampled to 44.1 kHz, causing an even worse sound quality. OSS4 justs works, has less overhead, a smaller latency, a much nicer API, and a much much much better sound quality. 3. level 2. Anonymo.

Re: ALSA as audio server instead of Pulseaudio? Thu Dec 12, 2013 9:17 am. Well, yes, you can disable Pulseaudio by removing it from your installation, but we advise against that. If you use an outdated KDE, you might consider updating first, current in most distributions is 4.11.3 or even higher.
PulseAudio vs. AudioFlinger: Fight! – Arun Raghavan
https://arunraghavan.net/2012/01/pulseaudio-vs-audioflinger-fight/
PulseAudio’s power-saving features are clearly highlighted in this comparison. AudioFlinger causes about three times the number of wakeups per second that PulseAudio does. Things might actually be worse on older hardware with less optimised drivers than the Galaxy Nexus (I’d appreciate reports from running similar tests on a Nexus S or any other device with …
