Hey @MichaelP, glad to help. The reason PulseAudio is still useful is because you may have multiple audio servers running, not just ALSA. For example if somebody is doing audio editing work they'll often use the JACK audio server for that, which is better suited for low latency audio work, but still use ALSA for general audio.
Why PulseAudio? – Vidar's Blog

PulseAudio uses a high quality resampling algorithm by default. ALSA supports only one, a simple linear resampler. If, like most people, you can’t hear a difference anyways, you can configure PulseAudio to use a linear algorithm too by adding “resample-method = src-linear” in /etc/pulse/daemon.conf. CPU usage will drop from 10% to 1%!

PulseAudio can route audio from multiple sources to multiple sinks, both locally and over the network. You can use it to combine multiple soundcards into a single virtual device, to forward music from one PC to another, or to share a single microphone as an input between multiple PCs. The best place to start learning is at the PulseAudio wiki.
10.10 - Why does Ubuntu use Pulseaudio? - Ask Ubuntu

As to "why" they chose pulseaudio as the default, I don't know. It probably has to do with a lot of the same reason why they switched to Empathy as the default IM client. Those reasons (at least as far as I know) are related to the framework used in the backend. PulseAudio has a very good backend even if the implementation isn't 100% yet.
Pulseaudio vs ALSA - Ubuntu Forums
https://ubuntuforums.org/showthread.php?t=1794581
Pulseaudio is a sound server which allows multiple sound sources to be fed through to one or more sinks. AFAIK Alsa only works with one source at a time.... Actually I think that is wrong and Alsa does support multiple concurrent sources. Found this diagram showing what it does: Appears that pulseaudio is as well as, rather than instead of alsa.

Hey Guys, I wanted to understand it seems like the community is pushing for users to switch from PulseAudio to Pipewire. Is this still the case, and if so Why?

alsa - Why does aplay work when pulseaudio is running …

4. This answer is not useful. Show activity on this post. Read this link. It states that alsa (aplay) is configured to send its output to pulseaudio (which is your sound server) by default. When your sound server is not running you will not be able to hear a sound as you have observed. See also "PulseAudio Removal"section to detach it from alsa.
