I listen to audiobooks and podcasts on my commute, so I don't want Waze to make any noise. I have mute set to ON, which turns off all the turn by turn speech, but it doesn't silence the speed camera alerts. I had previously set 'Prompts Volume' to zero in the sound settings screen, which worked, but since the last update things have gone badly wrong.
I noticed on my drive to work this morning - and I use the M6 past Birmingham which is littered with a crazy number of speed traps - that Waze was literally telling me about speed cameras every three seconds. Annoying, to say the least. I checked my settings and 'prompts volume' was still on zero. I fiddled with the volume control and managed to set it back to zero again. However this didn't entirely solve the problem, as Waze was still muting my audio when it would have played it's speed trap warning.
On my way home today I fired up Waze again and immediately noticed that the prompts volume, whilst still set to zero, was again being ignored and I was being told about speed cameras every few seconds.
In the end I task killed Waze just so I could listen to a book in peace.
