sound issue playing music and voice navigation

rinigus

Pure Maps is using QML Audio for sound. We tested SoundEffect as well on SFOS, but it had some issues with the bluetooth - will have to retest it. I don't know how to patch it to PA alert. You could see if SoundEffect will work for you (change it at https://github.com/rinigus/pure-maps/blob/master/qml/pure-maps.qml#L88) and whether it works better.

Never got anywhere with Qt/QML or clickable before. Good opportunity to change that. Will try my best. Might take a couple of days, though.

@padu , indeed! there are too few on mobile linux side - have to get hands dirty at some point. Good luck!

Wow, that turned out to be quite easy (on Ubuntu 20.04). I have not been able to do production tests, yet, due to missing API keys.

Am I correct that I need one key for Mapbox for tiles rendering (Western Europe) and one key for MapQuest for the routing service?

I did test audio with the TTS test in the settings section. (Compiled the slim version with Pico TTS only.) After applying the following patch

-    Audio {
+    SoundEffect {
         id: sound
-        autoLoad: true
-        loops: 1
         }

as per this GH issue comment, test voice was mixed with existing audio at the same volume level. No pausing and no damping of other audio streams. Tested with phone speakers and Bluetooth headset connected to N5 and OPO. No Bluetooth problems otherwise.

@padu , can you change the volume of the instructions? this seems to be the second issue with this approach

@padu: forgot to reply - yes, you need mapbox api key. or use osm scout server offline for testing

SoundEffect property volume has an effect with and without Bluetooth (tested with N5 and headset). Or do you mean changing volume with buttons?

rinigus

@padu: yes, with volume bottons

New Pure Maps release 1.29.0 contains a patch that applies audio role notification to voice directions. Normal audio, e.g., music, is no more stopped, but damped now.

VW carkits have an infamous bug, that auto-mute Bluetooth audio after music was paused/stopped. When the next voice direction came in, unmuting took some time, cutting-off part of directions. This problem does not happen any more with the new Pure Maps release.

Using Ubuntu Touch as daily driver got a little more comfortable again. Thanks @rinigus and jonnius!

That's thanks to you for finding it out
