Ubuntu pulseaudio setup is evil. Effect of removing it needs work on alsa configuration to bring sound back to operational. Sorry to say you will have other bugs from time to time from pulseaudio. Reason why you had no sound is so simple. Ubuntu no longer configures alsa in a operational state for all sound cards without pulseaudio. They disabled configuring dmix in alsa for cards without onboard mixer. So yes jerriy major distribution problem. Audio should be left configured in a operational state. Without a mixer only one application can interface with sound card at a time. Guess what gnome connects to sound card so there was no sound interface free for wine. Nice way to trick users into that something defective is needed. Make the one that works dependably defective by stuff up configures.
