e. Expand the "Control" Key
f. Expand the "Class" Key
g. Look for a key containing the following string of letter and numbers:
h. Highlight this key by left clicking once on it
i. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these delete them by right clicking on them and choosing "delete"
j. Exit the registry by clicking on the "X" in the top right hand corner of the screen.

then restart your computer
I don't see anything related to "Upper Filters" or "Lower Filters" So now what happens or what can be done? delliott54@gmail.com
<p>I followed instructions to a T but no folder marked Upper or Lower at all ? Plz help herbie.underwood@yahoo.com</p>
Great instructable! My driver has been acting up so I called the <a href="http://www.cpumedics.com" rel="nofollow">cpu medics</a> and they weren't much help. I'll have to see if my husband can do this and fix it up. Thanks for sharing!
I only have upperfilters no lowerfilters help?
Worked like a charm. Thanks a lot, after 8 hours trying I figured I might as well try instructables and found you post. I just can't help but wonder how did you come up with this magic.
dude wen i did that i found dat long number but wen i look rite hand side it doesnt say upperfilters or lowerfilters it says some other stuff i found dat says upperfilter but i didnt see lowerfilter
ok. ill check that out. before i posted the first time i was looking for a free driver update, all i got were free trials.. it all depends, ive run a couple of programs to increase productivity. i would say it has a dowload at a speed of....110 kb/sec
I successfully located 'UpperFilters' but it would not let me delete the value. As for 'LowerFilters', that was not in the folder specified. please help, i would appreciate it very much
Then your regristry is toast warm buttery toast but dont worry try deleting the driver for the device then re-install it
yeah thats the problem, there is no longer a driver for the sound and now im trying to get it. its my friends comp and it so screwed up.....
first does his computer have limewire or any downloading app second get CCleaner check it up on google it is free and it can clean GB's of a computer in a mere 20 mins. ohh and tell me how slow is his PC
