From past few days, I am getting wired problem. I have Windows7 and Ubuntu 12.10 installed in Dell vastro 3550.
When I boot in Windows7 and re-install the audio driver from the Device Manager Wizard, sound works properly.
And then when I boot in Ubuntu, audio is working well here also.
But again booting in windows7 sound in not coming. Reinstalling the audio make it working even after I do a restart and boot in windows 7.
Booting once in Ubuntu make the audio dump in Window7.
Is anyone is having this problem. Any idea or suggestions?
