Ever since I upgraded Dapper to Edgy, I have this weird issue of no sound in Vista (yeah, I know it sounds kinda unrelated but this is what I've zeroed in on). The problem is if I boot into Vista after a previous session in Edgy, there's no sound in Vista at all and the only way to restore the sound back is to reboot the system, looks like Edgy updates certain register values of the sound card which Vista is not able to understand. I don't know whether the bug is with Vista or Edgy; but given how fast MS folks are at fixing the "bugs" due to incompatibility with other OS, I'll most probs submit a bug with Ubuntu folks. Edit: Submitted the bug on Launchpad, here is the bug link; in case you're interested: https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/121674
In other news, Vista also doesn't recognize my Pan-digital photo-frame; and I don't see any drivers for Vista on their site either.
