How to properly make sound on Arch Linux?

Question

linux

Do I need to install pulse audio? What for? Will Alsa + Pulse Audio be enough to make sound work in Skype, browsers, players, etc.? Do I need to somehow configure Alsa / Pulse Audio additionally or does everything work out of the box? With standard configs, will the sound be automatically transferred to the headphones when they are connected? Where can I read more about Alsa and Pulse Audio? How does sound work in ubuntu?
Throw instructions on how to make sound on Arch Linux (not archwikis)
P.s. yes i read archwikis

Answer 1

On Ubuntu PulseAudio over ALSA. As far as I understand, ALSA has exclusive access to the physical device, and PulseAudio allows you to mix sound from different sources (applications), apply effects if necessary (the same equalizer).
