Discord currently uses "call audio" for Android app calls which hampers functionality. I currently use a Galaxy S9+ which has an option to separate app sound and force an app's audio stream to Bluetooth or phone audio. Discord completely disregards this because the voice audio is classified as a "call" which degrades all other sound output from the phone in the background lowering the overall functionality of my phone.
If this is being done to save on data please set up a toggle to switch it to media output. please God
