Hello,
I have the G13 QCM6125 model for a 2015 Toyota Auris without amplifier. I had the firmware 20240903 but it also happens on the 20241022.
The music I play from USB as well as the radio are heard at a correct volume. The problem I have is that navigation instructions on Google Maps, WhatsApp audios or voice notes and Google assistant, are heard quite low, very much so, with respect to music playback.
I do not use Android Auto or Carplay, I directly use the device with a SIM card that provides the network connection, that is, I use the applications directly installed on the device.
These apps have no volume control of their own, only Google Maps has an option where I set the directions to the highest volume mode, but even then, the directions are barely audible.
I have tried turning the system volume down and up in Factory Settings to no avail, as the system volume turns up the volume on everything and therefore this turns up or down the volume on the apps as well. The problem seems to be in the difference in volume of what is system sound playback versus multimedia sound playback coming from other applications. Surely I am not the only one to whom this problem occurs, but it is true that most users who ride your devices, may not suffer from this problem because they use Android Auto or Carplay.
Please fix this, ince it becomes impossible to listen to Google Maps directions, Google Assistant and WhatsApp voice notes while playing music from the player or radio.
Thanks in advance.
Regards.
