Query: Can't use it with Mac OS

IOGear's website says this speakerphone works with Macs, but it's not true. At least, I tried it on two different Macs running Mac OS 10.4.8 and the sound that comes out is garbage, sounds like you're speaking underwater. Works fine on Windows, but that's not the point.I emailed and called IOGear and first got the runaround -- "you must be overdriving the unit" -- but then they told me it is known not to work with Mac OS 10.4 and there's no ETA for a fix.
