I've used and loved Ubuntu since 9.10, but the problems I've had since upgrading from 12.10 to 13.04 are driving me back to Windows. Currently the worst problem is that I have no sound. I've searched the forums and found advice to uninstall and reinstall alsa and pulse-audio. That seemed to work for a day or two but then lost sound again and doing the uninstall/reinstall procedure no longer works. Everything looks fine in the sound settings except that the output says "dummy" something.

Other problems since upgrading include hanging on exit and an enormous headache with UEFI settings to get the upgrade to run in the first place.

I really don't like Windows, but I've got to have sound!

Can anyone help?

Thanks!
