Comment (by fackamato):

 Has there been any change to this? I know in Ubuntu Intrepid pulseaudio
 (0.9.10-2ubuntu8) doesn't use the sound card's capabilities by default.
 Also, it's true that most sound files are 44.1kHz, but then again most
 sound cards have an internal sampling rate of 48000Hz, which means it goes
 44.1 source > PA 44.1 > card (internal 44.1 > 48k resampling). If we set
 PA for 48k, it would be awesome when playing DVDs for example (48k all the
 way through), and for MP3 etc it would be 44.1k > 48k > 48k. Don't know
 which is better, resampling on the card or in software? My guess is that
 software resampling would be more accurate (I've no idea on the
 performance penalty though).

 Or I might be talking out of my rear.., not sure. Any updates?
