Funny how, a couple of years ago, when rebooting from Win to Linux, 
when one didn't get sound in Linux, it was always Linux' fault...

As at least Jojo mentioned: It's not K/Ubuntu's fault if Win7 fails 
to properly initialise the soundcard. Probably a driver problem in 
your Win7 install. Third party Win drivers aren't known for their 
quality, you know...

If this is so big an issue for you, why don't you just use Mandriva 
exclusively? Or do a proper shutdown-start cycle? It doesn't really 
take more time...

Yeah, it actually does that...
Try getting some actual information instead of just looking through 
boot messages - not everybody logs everything...
