No Sound in Limited User Account

by on Sep.17, 2010, under Windows

Recently I needed to do a repair install on Windows XP, after which sound was no longer working on limited user accounts. After extensive searching I realized no one had a solution. The device driver was ok and operating and sound was working fine on administrator capable accounts.

The strange thing is that the Realtek HD sound app worked Ok on the LUA. I concluded from this that the software enumerator was at fault, specifically the registry keys that would have to be read for the software enumerator to read its current list.

Use regedit to change the permissions of the tree on currentcontrolset to fix this issue. Log in again and its all good.
