Stereo Sound switches off on navigation at warnings?

If you can go into the factory settings, have a look for system volume and radio volume. I found that Igo's sound runs through the system volume, so it was a case of patience and playing with these settings between the radio and system volume to get the balance right between the two. Also, if you have an option in the driving settings to mix or cut radio off, I found the mix works better. The radio volume will drop but Igo will talk through my front right speaker and when finished the radio will come back up.

many people has this kind of problem... as android car head units become more famous...
In my case , i didnt have this problem until the moment i tryied to install luna pongos skin instead of arimis....
with arimis skin everything works well.. .the tts sound was mixed higher than the musics sound...

after i install pongos skin... settings lost...

1.tryied to experiment with [sound] commands on sys.txt file on both skins... no luck..
2.reinstall vocalizer ([Only registered and activated users can see links. ]) fix settings... no luck
3.work with android head unit factory settings... still no luck....

i hope other members-admins-masters etc have found out a solution for this general sound problem....

With Igo Nexgen Israel (NOT with Luna or other versions) if you use the internal TTS engine (folder "tts_nua_ve1" with the files of your preferred language, located in the main folder of Igo) the music of the car radio is lowered correctly when Igo speaks, and restored when he finishes speaking.

Prerequisite: the car radio must have the internal function "Navi remix" or something similar.
This works (at least for me) ONLY with Igo Nextgen Israel, with other versions of Igo Nextgen no, since they do not support the use of "tts_nua_ve1" to manage the TTS.

today i noticed that when "ding" is activated, the device is lowering the music for the ding sound...
i believe that the problem with Stereo Sound doesnt switches off on navigation at warnings, its because 2 reasons...

1.tts wrong file selected

2.commands in sys.txt

ps.i havent yet try solution because i dont have enough time...

I have already explained the reasons and how to act...and what type of Igo/version to use.

In sys.txt use this:

[sound]
dev_buffer_size=200
sound_effect_unmute_delay=100000000000
log_sound_effect_muting=0
android_muting_device=0
media_config=config/devices/media_android.xml

@Bixo
luna pongo skin - android 12
doesnt work... maybe something interferes inside sys file... only ding sound mutes the music... not the tts voice.
pls have a look on my sys... if you can find something wrong....
thanx in advance

Spoiler: sys

i have an igo luna 9.35.2.1538 on a samsung under android12with overlaying the pongo skin

this is the minimalist sys.txt with which this igo starts

Spoiler: min sys.txt

it is not always advisable to fill the file with parameters that are not known, or that are specific to a device.
It is enough for a single one not to be suitable and it is igo which closes or simply plants.

it is always possible that additions a posteriori will not change anything but a small additional thing can tilt the balance of the wrong side, and since certain values are stored in the profile of the save folder, it may prove necessary to purge the latter when we want to start again with different parameters.

Good luck

sys.txt replace/change your sys value and try:

[android]
navigation_audio_stream=4

and use ONLY this values for "sound"

[sound]
dev_buffer_size=200
sound_effect_unmute_delay=100000000000
log_sound_effect_muting=0
android_muting_device=0
media_config=config/devices/media_android.xml
