[pulseaudio-discuss] Module-combine adjust time question

Hello all,

I was wondering about the specifics of the adjust time option. In the 
wiki there is a comment that setting the value to 0 will cause no 
periodic sample rate adjustments ever. Does that mean that all sinks 
will remain at their default/native sample rates (and thus no 
resampling) for all time or is there an initial adjustment (and thus 
resampling) on startup? I assume this would cause the audio playback to 
slowly drift apart between sinks, but would that only be true if there 
was a continuous audio stream or would the buffering re-align every time 
audio stops and the streams go corked/silent?

My goal behind this question is to get max audio quality (ie eliminate 
resampling if possible) while maintaining reasonably good playback 
alignment between devices. Each playback device is in a different room 
so perfection is not necessary.
