Upgrading wine, no audio, winetricks GUI missing from dash

view story

http://ubuntuforums.org – Hello, 3 problems with Wine: 1. "$ wine --version" returns 1.5.20. I'm trying to install v1.5.28 from the PPA, though "$ sudo apt-get install wine1.5" states that "wine 1.5 is already installed". How do I upgrade wine? (would rather not build from source, but I'll do that if there's no other choice). 2. My wine installation doesn't play sound. How do I fix that? 3. Since upgrading to Ubuntu 13.04, I can only access winetricks' GUI using the terminal command; it's missing from the Dash. Any way to fix that? Thanks in advance, if any info is missing please let me k (Hardware)
