Native sample rate and speaker configuration

Description

At the moment PA hotplug module starts all sinks with a rather conservative channel model and sample rate: stereo 44100 Hz. It would be best if PA could autodetect the best features of the card and start the sink with them.

  • type changed from defect to enhancement.

We could easily do this, however this would then require resampling for almost all cases, since the vast majority of audio still is in 44100hz. Since our resampler is not as fast as I would like it to be people would most likely start complaining.

My plan is to increase the default to 48khz as soon as we have an SSE resampler in place (which will happen very likely very soon).

Oh, and for the speaker configuration: most soundcards do surround sound sound these days, however only a minority has surround speakers attached. Unfortunately we cannot auto detect what kind of speaker set is attached. Thus we will make this selectable in pavucontrol eventually, but still default to stereo.
