Check your logs. This is quite possibly the difference between "My
hardware does 44.1khz natively" and "My hardware only does 48000khz and
playing anything but a DVD requires resampling". Later Intel chipsets
all seem to be the latter.
Not sure if this is the right place to post this, but I also have a huge
CPU hit on my 4+ year old laptop, and I am sure that it handles
different sampling rates without much difficulty.
So, my question is, what logs can I check to find out if this is
happening (if I understood the message correctly)?
