PulseAudio features I have used in the past that I don't think ALSA has:

* playing audio from/to another Bluetooth device (with bluez)

* playing audio on a PulseAudio server running somewhere on the network

* transparent encoding of audio output as DTS (for surround support over SPDIF)

I also seem to remember plain ALSA having trouble with multiple applications playing sound at the same time, which is just pathetic.

I'm sure some of these could in theory be built on top of ALSA, but fact is that today's Linux distributions use PulseAudio, and for me it always worked well.
