The idea behind pulseaudio is live switching of streams. ALSA is great |
| 2 |
if you have only one audio card, but as soon as you introduce a |
| 3 |
bluetooth headset, a headphone, a HDMI display with sound output, ALSA |
| 4 |
can't handle real time stream redirection. Sure, you can use scripts |
| 5 |
to toggle .asoundrc profiles, but even then you'll need to restart the |
| 6 |
softwares that produce audio. |

Here I have a HDMI display (an hdtv) and a headphone. I mostly send my |
| 8 |
audio to my tv, but if I'm using the computer late at night, or if I'm |
| 9 |
to listen to high volume music, I'd switch the affecting streams to my |
| 10 |
headphone, without the need to mess with sound configuration files and |
| 11 |
to restart my sound engine. |

PulseAudio is to audio what X.org is to video: stream mixing software. |
