My Question or Issue

Whenever I'm in a discord call, the sound quality from Spotify is dreadful. My headphones are Sony WH-H900N and connected through bluetooth. I saw that switching that my input source to the internal mic might solve the issue but it hasn't.

When you're using a VoIP call, usually your operating system switches the Bluetooth codec to a suitable one for bidirectional audio called SBC. It's not a Spotify problem.

You can check this pressing Option while checking the Bluetooth menu option, then selecting the device, then checking the codec.

To fix this and force the use of AAC or aptX: https://9to5mac.com/2018/08/31/mac-how-to-force-aptx-aac-on-your-supported-bluetooth-headphones/
