Realtek vs. BootCamp via 1st Generation 21" iMacs

So many of you all have reported that the sound quality from the 21" iMacs either sucks (strange swooshing or crackling sounds) or doesn't work at all under Windows XP/Windows 7.
Well, not to worry;  you aren't alone.

This is a known issue through Apple and BootCamp, and we here at the Labs & Classrooms office feels your pain.  We have updated Boot Camp drivers (now running 3.1),... and we have installed May 2010 drivers (WDM_R248) from the Realtek website...

Perhaps this will help!

Areas this affects:
All dual-boot 21" iMacs (1st, 2nd, & 3rd Gen).

We'll post a couple of comments to follow-up.
Thanks for reporting your concerns!!!
