MacBook Pro 2019
macOS Catalina (Version 10.15.1)
When using the desktop app for Spotify on Mac with the streaming quality setting set to "Very High", or any other quality for that matter, and I open up Google Chrome the audio stops for 1 second and when it returns it is playing at the lowest possible quality.
This does not happen when using any other web browser; only when using Google Chrome.
Solved! Go to Solution.
Just an update for anybody else that has the same problem.
It only occurs when using earphones or headphones that can be used as a microphone.
Go to System Settings>Sound>Input and change the input from the AirPods (or whichever earphones/headphones you are using) to the MacBook Microphone.
This has solved the problem for me.
