Comment (by zman9001):

 Thanks you for your reply. I wasn't aware that a mailing list could be of
 use in these matters I was rather looking for a pulseaudio forum (which i
 didnt find).

 Anyway, I have in fact set the default-sample-rate parameter to 96000 and
 am using speex-float-5 to resample other rates. I suspect that this is
 working as it should because pulseaudio uses about 11-15% processor when
 I'm playing back 44.1 and 48 kHz files as compared to about 3% when
 playing 96 kHz files. In any case I don't have a problem with saying
 goodbye to system sound effects if it becomes an issue. My concern was
 whether alsa was messing with the signal in any way before it reaches the
 soundcard. I don't ''think'' it is because I would notice processor load
 somewhere but I don't know anything about the intrinsics of software sound
 transfer, which is why I came here for a word of advice.

 Also, what's this about module-alsa-card support and profile switching?
 I'm not sure what you mean by that. I suppose I'll look into it now.

 Thanks again for your reply,
 Rob
