This is more of a work around than a fix but it works for me..
Log in as a user with admin privelleges
Open notepad and type NET START audiosrv
Save
file in C:\ or somewhere you can find it easily, also make sure its saved as a batch file (enter .bat at the end of the name)
Open Task Scheduler
Create Basic Task
Type a name e.g Audio Recovery then
next
Choose
the option “when
I log on” then
next
Choose
Start a program
then next
Browse
and select the batch file
from earlier and next
Check
the box and
click Finish
In
General tab,
choose Run
whether user is logged in or not
In
Triggers tab
click edit
Change
specific user to the affected user’s profile
Choose
to Delay task
for 30 seconds
and click OK
Click OK again
then log out and in and it should work
Cheers,
