Hi ! I got the same problem. I have Vista Home Premium (32 bite) and i mistakenly disabled the sound. There is a red cross on the speaker icon at the bottom right corner of my computer and when i opened the playback it said No Audio (output) Devices installed.
I followed the above mentioned steps and disabled it many times but it didn't help. Now, when i check it has completely disappeared from the device manager list. Actually, it was listed under portable devices.
Please help me reinstall the sound. I don't have any sound installation CD either :'(
First of all. Find out from you specs of the pc which sound card you have installed, then go to the manufacturers site and download the latest drivers for that sound card. You are properly trying to install a driver that is old or not compatible.
As for the WPD, I have windows 7 and did the actions below which fixed my problem.:
Here's how I fixed the Blackberry. You can use the same aproach for any USB removeable for Vista or XP.
1. My Computer -> Properties -> Advanced System Settings. This takes you into the system properties like in XP. Go into Environment variables and create a new System varable called "devmgr_show_nonpresent_devices" ( without the quotes - I don't think it's case sensitive). Set this to a value of 1.
2. Go into device manager. From the view menu, choose "show hidden devices". Because of the environment variable, you now see all devices not in use.
3. Uninstall any "Universal Serial Bus controllers" not in use (greyed out). Also I uninstalled any storage volumes, storage volume shadow copies, and disk drives also not in use. You should see your offending USB device in one of these areas.
Now try plugging your device in and see if it now detects. You should be ok now, even after a reboot.

I put the original author to show my gratitute. How did it fix it?
For some reason the device manager filled up all 26 drive letters with bogus ports!! so If you plug in another device it cannot be given a drive number, hence, doing the above takes away the drive numbers that are bogus and ...wolla ..now everything works !!!
