What is the difference between ALSA and PulseAudio?

As far as I know, ALSA is a package of many sound card drivers, and PulseAudio is a audio application that operate the sound data like mixing or equalizer.

Does PulseAudio need ALSA?

PulseAudio is a software mixer, on top of the userland (like you’d run an app). When it runs, it uses Alsa – without dmix – and manages every kind of mixing, the devices, network devices, everything by itself. In 2014, you can still run only ALSA.

Why is PulseAudio using so much CPU?

The key insight here is that pulse’s job is to route, mix and resample audio from apps to the correct device. Different apps/devices may have different samplerates (e.g.: 44.1khz to 48khz) so pulse is resampling which will typically require a lot of cpu resources.
