Unable to uninstall Audio Driver – Realtek, Sound not working

A system at the office was having the Realtek audio control panel icon showing up in the system tray, with the 3d test working, but windows wasn’t showing the audio device in the sound and audio control panel applet. Instead windows said that not audio playback device was found. As a result no applications were able to play audio.

This post at tomshardware.com provided an easy solution.

Just open regedit and delete the key folder //HKEY_LOCAL_MACHINE/SYSTEM/CONTROLSET001/ENUM/HDAUDIO and restart your computer. It should prompt you to install the hardware again.

That fixed the hardware issue and the user was able to view www.abcnews.go.com/whatwouldyoudo happily. :)

CD burning software could not find a valid recorder error

Update: Using this method causes problems in that the drive is not automatically polled regularly. So if you insert a disc, you will have to open the CD drive in my computer to see the files in it. Use BurnRights bundled with Nero to give burn rights to users. Thanks to Jomon in Kerala for the reminder to update. :)

I was having a bit of a trouble allowing users logged in to the domain to burn cds from their systems. Seems the admins at HO had changed some security setting and domainwide people were facing this problem. Luckily for the Delhi users Jeba Singh Emmanuel was there. ;-) Of course, I got the solution from Ashampoo Burning Studio 2007′s help file.

I needed to change allocatecdroms from 0 to 1 in HKLM/Software/Microsoft/WindowsNT/CurrentVersion/Winlogon in the registry

Voila, CD Burning works. If only the admins had told me this. It would have saved me some 30 minutes.
