I cant find the LowerFilter, is another name for it IconPath?

I don't see anything related to "Upper Filters" or "Lower Filters" So now what happens or what can be done? delliott54@gmail.com

I followed instructions to a T but no folder marked Upper or Lower at all ? Plz help herbie.underwood@yahoo.com

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.....
