I've been having the same issue with the "faint" Say-A-Command. However, it is only intermittent.
Also, I find that, at times, even though my bluetooth shows connected, it's actually using speaker phone. This is a total pain in the rear. I usually have to turn off both my Jawbone Icon, and the bluetooth on the phone, then turn them all back on. Sometimes it will repeat this, in which case I do it all over again.
