1. How to increase the volume in Spotify

If you're used to listening to music through Spotify, you may have trouble with the volume in that app individually. Android Auto users have noted that the volume of voice notifications stays at normal levels, while the music player volume gets quieter or changes at inappropriate times.


You need to go into your Spotify settings and check your audio settings. Through the settings, you can change the volume by adjusting the mixer sliders to the desired level. Here are instructions on how to do this:

  1. Launch the Spotify app on your device.
  2. Select the song or album you want to play.
  3. Tap the volume icon in the bottom left corner of the screen.
  4. Drag the slider to the right to increase the volume.
  5. If you want to increase the volume even more, tap the gear icon in the top right corner of the screen.
  6. Select “Equalizer Settings” and then adjust the sliders to increase the volume.
  7. Tap "Done" to save your changes.

2. Increase the volume through the head unit

Sometimes the navigation sound in Android Auto disappears suddenly. Adjusting the volume via Android Auto does not help to solve the problem. In this case, it is recommended to change the volume using the hardware head unit control buttons instead of the software method.


Each head unit has its own volume settings. These can be used to increase the volume of both Android Auto, and other apps that are used on the head unit.

In order to change the volume using the vehicle's capabilities, you will need to study the vehicle's device by opening its manual. You can find it in paper form or as a pdf file on the manuals website.

You need to find the following information: head unit volume controls. Using these hardware buttons, you will be able to fix the sound in Android Auto without actually using the phone's own settings.

3. Deactivate the built-in equalizer

Owners of OnePlus devices (e.g. 6T) on the forum share a problem: the sound settings in Android Auto do not work, the volume remains at a low level. No action helps, and playing music at minimum volume. In addition, the sound sounds distorted.


Check to see if there are any other equalizers installed on your phone. To do this.

Step 1. Go to Settings - Apps.

Step 2. Make sure there are no apps named Equalizer in the list.

Step 3. If necessary, remove all unnecessary apps and audio add-ons that may affect the overall volume of the head unit and Android Auto.

4. Disable the audio player equalizer

If you are listening to music via Spotify and notice the volume drop in Android Auto, disable normalize sound by going into Spotify settings.

Step 1. Open the Music app on your Android device - AIMP, for example.

Step 2. Select the song you want to turn off the equalizer for.

Step 3. Tap the three vertical dots button in the upper-right corner of the screen.

Step 4. Select "Settings" from the drop-down menu.

Step 5. Tap "Equalizer".

Step 6. Toggle the switch next to "Equalizer" to the off position.

Step 7. Tap "OK" to confirm the change.

5. Unplug and replug the USB connection

The sound problem is often observed not only on Spotify, but also on streaming services like Google Play and YouTube Music. Changing the volume via head unit does not produce the desired result.


If Android Auto is running via USB connection, disconnect the cable and reconnect it to the car. With this simple action, you will reset the audio settings on your phone. Properly, this helps normalize the sound not only for in-car navigation, but also for apps like Google Play or YouTube Music.

If this action didn't help, additionally check the volume settings through another audio player. For example, go into the radio or XM and check if the volume settings have been restored to the level you are comfortable with.
