Anyone use Logitech Z-Cinema speakers?

Anyone using these speakers on your Mac?
They are USB speakers and Logitech does not make drivers for them for OS X. Thus, they do not work properly. I can not adjust Bass or Treble, and the Volume adjustment isn't vary good (can't get it vary low). I have been dealing with Logitech support and they said they should work with OS X's drivers. Welllll they don't, after multiple emails back and forth they said to check to see if my audio drivers are up to date. Witch I am pretty sure they are. They directed me to this link http://www.apple.com/downloads/macosx/drivers/ and I can't even find audio drivers there.

So anyone use these speakers on your Mac? Or anyone have a clue what to do. Since logitech support is not vary good.

 

My buddy uses these speakers and has the same problems as you do. He ran the software update, and it seemed to fix the problem. I'll have to check back with him to get the specifics.

 

My software update does not have any update for audio. If you can find out exactly what he did that would be great

 

Well he said software update, but he got confused on the terms.

That's what he used. They're made for the z-10's but the worked for him on his Cinemas.

 

I tried that before, that's only really for the LCD witch these don't have.

How can I check to see if my audio drivers are up to date? Since software update doesn't say there is a update I'd assume they are up to date.
