I've tried changing my main volume, changing my ringer volume, turning bluetooth on or off, toggling the sound through the speaker, toggling the "Prefer Bluetooth" option, and none of it helps. I do use the phone connected to the Sync system in my car (which has its own problems), but 3.0.1 had no such issues. I love that I can set a volume for the app itself now, but only if it actually worked.
iPhone 4S, 5.0.1 (AT&T)
I was having the same issue and it was driving me crazy... But then I figured it out. There is a separate OS related volume, that I can't seem to access anywhere, except when noise is being played. Try this... Click "Navigate" then choose a location (home, work, etc) then when the route summary appears click "Go", then immediately, click the "up volume" on the side of the iPhone and you will see that the "OS related volume" was low... (or at least it was on mine).
(The point of this method is to force waze to play audio "Let's go" and then tell the iPhone that you want the volume to be higher on that audio)
