There are certain quirks I've noticed with these kinds of settings. None of them are really Waze's fault. Maybe some of them will be helpful to you.

One in particular I've found frustrating: with "Prefer Bluetooth" set on Waze, Waze will normally use the Bluetooth handsfree (as if on a phone call) to give instructions. This happens with the stereo off or on AM/FM/CD/USB. If I'm using Bluetooth Stereo to stream music from the same phone, the Waze instructions fade the music out and come through all the speakers, which is fine.

The problem sets in when I switch from BT Stereo to the radio or something else: even though BT Stereo isn't active on the car end, the car stereo (in my case Ford Sync) is unable or unwilling to tell the phone that. So the phone still thinks the BT Stereo connection is active, so Waze is still trying to send prompts that way. To fix, I cycle Bluetooth on my phone and reconnect the handsfree.

It seems to be a limitation of either iOS, Ford Sync, the Bluetooth protocol, or some combination thereof, so it's likely nothing Waze can do anything about. Such is the price we pay for integrating a GPS app into a smartphone.

I've been having intermittent sound issues with waze on iphones since the beginning. Sometimes it will play through the phone speaker when I select that, sometimes it won't. Sometimes it will play through bluetooth when I select it, sometimes it won't. Sometimes it will start a trip by working through bluetooth, then it will fall silent part way through.

Its infuriating enough that I've stopped depending on it.

It would appear that the iPhone sees the USB connection and sends all sounds (except the phone ringer) through USB instead of playing them over the phone.

It's entirely possible that it's played sounds over the speaker when charging before—this happens to me once every couple weeks—but that isn't normal behavior. For me, it only happens when I overwhelm Ford Sync, usually by unplugging and plugging it back in too fast, such that Sync doesn't mount the USB drive but the phone still gets power over USB. When the connection works properly, though, it sends all sounds over it (besides rings and alarms) whether or not it's active.

For as long as I can remember, the only sounds the iPhone will play over its own speaker when plugged into a USB/dock connector/Lightning audio player are ringtones for incoming calls and alarms. Other notification sounds will lower the music volume slightly and play the notification sound over the music through the USB connection.

I suspect this occurs because the iPhone is for some reason incapable of playing sound over both USB and the phone speaker at the same time. Rings and alarms are the only sounds the phone makes that pause the music entirely, so the phone can stop playing over USB entirely and switch audio to the phone speaker. With other alerts, the phone would not be able to play the alert over the speaker without either pausing the music or cutting the music abruptly from the USB player to the phone speaker and back. Since these alerts are typically short and don't require intervention to be stopped, unlike calls and alarms, cutting off the music would be too abrupt.

I can't speak for everything, but I've owned a FIAT and a Ford, and on both their stereos this is how it happened when the iPhone was plugged into USB, even if USB wasn't the selected audio source. If I wanted to charge my phone via USB while listening to the radio, I simply wouldn't hear any alerts for texts, Twitter, or Waze.

Occasionally, if the audio system was being screwy and the USB didn't connect properly, the phone plays all sound over the speaker, as if it were connected to any old charger. However, since it wasn't actually connecting to the stereo, I couldn't play songs from it.

If your phone doesn't act in the way I described, possibly your stereo works differently than mine. But your saying that the phone volume control is unavailable when USB is connected says to me that it's probably the same. I would wonder if it's possible you were mistaken about audio playing over the speaker instead of USB when Waze hasn't been opened yet, or if that's just a coincidence because your USB connection hasn't been picked up yet.

The biggest problem was text messages where they would only flash in the banner at the top of the screen when running Waze (since the phone was already awake). I changed my notification settings to use the alert instead of the banner, so hopefully this will make the incoming text more visible while Waze is running.

Is there a setting that will force Waze to route sounds to the phone speaker, even if its connected to a radio via USB? I have tried setting "Always play sound to phone speaker" to both on and off with no success.

When I use Waze in my truck, I always have it plugged into the radio to charge the battery, but I'm not always playing music from my phone. If I'm just listening to the radio, no sounds (except for the phone ringer) can be heard. Text messages, calendar reminders and all Waze alerts are silent, I only get the on screen popup. If I'm playing music from my phone, then all of these sounds are played through the radio.

I've checked the volume and it is maxed out before I connect to the radio. Once I plug it in, I lose the device volume slider.

If I don't have Waze running, I don't have any issues with sound. All notifications are played as normal. It just seems that once Waze starts, it will always send the sounds to the radio whether or not it is being used.

I've sent logs every time...........

3 tickets so far, (no response on 4th yet)


Last time it looks like they were blaming it on the SD card as this was the final response:

"In some phones, Waze cannot function properly on the SD card, which is why we recommend installing it ONLY on the phone's main memory."


I don't have the memory to NOT have it on the SD card and never had this problem before 3.6


I was just posting here so that if other people are having the same problem, they'd chime in and Waze might actually try to fix the problem

Which would happen if the media volume was muted, eg if you've been watching a YouTube video and turned the volume down, that will effectively mute waze too.

If that's definitely not the case, there's not much chance the community on here can diagnose the issue, you should raise a support ticket at waze.com/support. Next time it happens send your logs and take note of the time they were sent.

No!

All sound just goes away (including the sound effects)

You're not muting the media volume are you?
