In rare cases, some smartphones, especially certain iPhone and Google Pixel models, may show that media is still playing after switching between media apps, but no sound is heard.
The cause of this is the way some apps and mobile operating systems handle Bluetooth audio output handoff between different applications. Occasionally, the audio signal is not correctly passed to the newly active app.
Quick solution:
- Tap Pause in the currently used app.
- Then start playback again by tapping Play.
In most cases, this will immediately restore the audio output.
If the issue persists, make sure that both the affected apps and the smartphone’s operating system are up to date.
