Can't remove wine 1.4 rc5

view story

http://askubuntu.com – I installed Wine 1.4 rc5. Later I realised that this wine won't work because there is no sound. I removed it using Synaptic Package Manager and installed Wine 1.2 which is the stable version of Ubuntu 10.04. Even though I install it. It's still showing Wine 1.4 rc-5. How can I remove wine 1.4-rc5 and install Wine 1.2 ? (HowTos)
