No voice on navigation #39

Closed Rootinator closed 3 years ago

Rootinator commented 5 years ago

Hello,

Unfortunately, no voice is played on Android-Auto when navigating. Not on Google Maps and not on Waze.

But the music gets quieter and then louder.

Is there a hidden volume control for navigation?

On the smartphone in Maps the voice is loud and active.

"Voice over Bluetooth" is disabled because the receiver does not support Bluetooth.

EDIT: I found the mistake.

I'm using an external USB sound card and it will not play any navigation announcements. Music is played.

The navigation announcements are played via the permanently installed sound card.

How can I make the Raspberry play everything, that is music and navigation, via the external USB sound card?

Are you using RPi?

Rootinator commented 5 years ago

Yes

gregd72002 commented 5 years ago

Android-auto is using alsa by default on RPi. Have you tried to change the default audio on on RPi to USB audio? Something around these lines:

options snd-usb-audio index=0

and disable snd_bcm2835

Music is already playing through the external USB sound card. The built-internal, I have also disabled. Nevertheless, no voice is played during navigation.

Rootinator commented 5 years ago

I would like to ask if there is already a solution, because I still have no voice output in navigation and "Ok Google" commands and hints.

The external sound card has been activated (music is playing) and the internal sound card has been deactivated.

@Rootinator no solution yet, I will have a look at this asap

Rootinator commented 5 years ago

Is there anything new about this topic?

viktorgino commented 5 years ago

@Rootinator managed to have a look at it, but i can only manage to get call audio working through Bluetooth. I'll have to have a look at different implementations to see if they managed to get it working through USB only.

Rootinator commented 5 years ago

That is, it will not be possible to hear the voice of the navigation (and from "Ok Google") over the Raspberry?

viktorgino commented 5 years ago

at the moment you'll need an external bluetooth adapter (A2DP doesn't work with the Pi's built in Bluetooth, nothing we can do about it), headunit tries to connect to the phone once AA has started, it worked for me so far. I'm still looking into whether if there is a better solution, but I'm not sure if this is supported on stock head units or not, I don't have access to one. But it should be doable as the voice channel is setup. Might need to send some extra config to the phone when setting up communication.
