Yeah it will be but you'd still not want to do any resampling in myth 
when using pulse. Pulse has it's own resampling framework and it would 
make sense IMO to use the same resampler system-wide, hence why you'd 
want to disable the resampling in myth and off-load this task to pulse 
(if you're using the native pulse output obviously - this wouldn't work 
if you go via the alsa->pulse plugin (well it kinda would, but you'd 
need the aforementioned setting to disabled the resampler!)).
