Hi Folks. Minor problem with the new system... Here's the situ: 32Gb Boot Camp partition created and installed XP SP2 from original disc. Inserted Mac Pro DVD to install the driver set (which was Boot Camp 2.1) Everything working correctly, except the sound - which comes out both the Mac Pro internal speaker and the LEFT channel of my external amplifier. Everything working fine through Mac OS X as expected. In Windows, I can change the audio out device from Realtek Audio out to the USB audio (which is the Apple Cinema Display speakers) but this is far from ideal for games, which is the only reason I'm installing XP. I have installed XPSP3 since and found a more up to date Realtek HD audio driver for XP, but no change. Has anyone experienced this? I may try to install XP again, install XPSP3, then install all the drivers manually as required to see if that changes anything. I'd like to get my legit copy of XP working rather than resort to Vista/W7 - as I don't know if my games will be compatible with the newer versions of Windows.
