These are all relative claims - PulseAudio claims to be lower latency than 
other software sound servers which may be true. It is considerably slower than 
using Alsa directly.

The problem is that most PulseAudio setups intercept calls to Alsa, MythTV 
thinks it's talking to Alsa but PulseAudio has hijacked the samples and is 
doing it's own thing with them. The only way we can be sure we're accessing 
Alsa is to kill PulseAudio first.
