gfdsa:

This is most likely the firmware rev of you bluetooth adapter. Early
revisions have a bug which causes a bit misalignment of the sco audio and
the result is 'white noise'.

could you post the output of 'hciconfig -a' on your machine.

also, what kernel and version of bluez-libs are you using? There are a lot
of bug fixes in the up-to-date versions. kernel ~ 2.6.20 and above and
bluez-libs 3.18 are the ones to use.
