Audio cuttet via Bluetooth

[Jan Weerheim]

Mijn ervaring: als de autoradio in gebruik is slikt de routebegeleiding bij mij ook de eerste woorden in. Als ik muziek speel via spotify (android auto) dan wordt alle teks wel uitgesproken.

[Jörgen]

I remember the TomTom Rider days when you could still edit the audio files yourself. Some headsets also had this problem. The solution was to extend each audio file by half a second at the beginning. This was because the Bluetooth connection had to be established before the audio file was sent.
I don't know how much this helps. Nowadays, the announcements are generated by the smartphone itself. Perhaps you would have to open the channel first and then start the announcement with a delay.

[Corjan Meijerink]

It's a frustrating issue indeed.
We verified that we do everything correctly (in theory)

I've delayed the start of the audio instructions by 1 second if you are connected to Android Auto but Android Auto almost seems to ignore this.

As users also indicate, the behavior differs depending on if you are listening to the car radio or to spotify. But we don't know what you are listening to.
We simply communicate to Android:

• MyRoute-app wants priority
• Please "duck" (lower the volume of) other apps
• Wait 1 second (if connected to Android Auto) otherwise we don't add an extra wait
• Speak the instruction
• Tell the OS we are finished so other audio can gain priority again

This is how it should work and how it works well for a lot of users.

The whole ecosystem of Android, the amount of different (bluetooth) configurations, Flutter as development platform and our priorities simply don't help in getting this solved

@Corjan-Meijerink, Indeed, the 1 second pause did seem to help, but it is just not enough, for my specific case I mean. You absolutely cannot introduce a longer pause everyone not having this problem My theory, not being held back by any knowledge, is that some AA devices simply do not honour the "wants priority" command, but listen to audio (voice) itself and decide (too late) to duck for themselves.

the behavior differs depending on if you are listening to the car radio or to spotify.

Yes, but that is quite logical. When playing spotify (or anything else) from your phone, the media channel is continuously open. The phone ducks spotify, and not AA.

In scenic for instance, I have 2 seconds audio delay and it works perfect.

[Haug]

Remark: this happens even, if the iPhone is directly connected to Bluetooth headphones without CP or AA

[Con Hennekens]

@Haug, thanks for this. This proves that not only MRA is struggling with this problem...
@Corjan-Meijerink, what do you think about this?

[M. Schrijver]

I've this problem also. Already for a while. It was introcduced in one of the latest 4.** version.

My headset did not change. The software of the headset did not change. The settings of my headset did not change.
The android auto setup did not change (built-in Honda Goldwing). The software of the Goldwing did not change.
The Android phone did not change.

But...
Offcourse there where severall software updates on my phone. MRA, Android Auto app, others apps.

When i play Spotify or other media, the audio of MRA is not cut of at the front. But if MRA is only source of audio. Then the first word or words (about 0.5-1 sec of text) is cut off.
This behaviour is in my situation very stable.

[Corjan Meijerink]

In the 5.0.1 update coming week it will be possible to configure your own audio delay

[Haug]

One remark: it has nothing to do with AA oder CarPlay, it’s even if you connect your iPhone directly via bluetooth without any CarPlay or android auto.

[Con Hennekens]

@Haug, Probably, but only when your head unit is doing the audio ducking of music playing from the head unit itself.

[Haug]

@Con-Hennekens I never hear Musik during motorcycling, I just listen to my boxer

[Con Hennekens]

@Haug, Sometimes I do, only when driving alone. But that is not the point. I don't use AA on the bike. I do in my car. No boxer sounds te prefer there

[Haug]

@Con-Hennekens
I use chigee with CarPlay but as I wrote, it has nothing to do with CP because the sound goes not via CarPlay and the cut of the voice is there, when contacted via Bluetooth to a headset or even to my Autoradio

[Con Hennekens]

@Haug, Yes, same thing... It happens not AA specifically indeed, but when an audio headend has its own failing logic for when to lower its music channel in favor of instructions from your phone, instead of trusting the priority commands of the connected equipment. So you are correct, it also happens with other then AA connections.

Most important thing: has it been solved for your specific setup?

[Robert Laudensack]

@Haug Yes I also noticed cut voice prompts. It starts saying something, but the cuts of in the middle of it

[Haug]

I set now a delay of 2 sec but the beginning of the speech is still cuttet.

[Con Hennekens]

@Haug, can you please check the version of the app?
Main screen, tap the account icon top right, scroll completely down.
What's the number there?

[Corjan Meijerink]

@Con-Hennekens We all know what number it says
This setting has only been available since the last update!

@Haug If the delay does not work could you share the following info?

• What phone are you using?
• What version of the above?
• Does the delay setting actually add a delay (disregard that you still have the issue but is there a noticeable different between 0 and 2 seconds)

[Con Hennekens]

@Corjan-Meijerink, yes of course, but I wanted him to find out for himself
The pre-public beta had this setting already without the wanted effect, didn't it?
