On Mac
When disconnecting Bluetooth earphones or
using them outside and returning home to use clamshell mode again,
sound often played through the MacBook speaker instead of a wired speaker.
I had to manually change the playback device every time.
There was no setting like Windows that prioritizes OS-level.
So I made it!
You can drag and drop sound devices to set priorities,
and automatically play sound from the device above the priority.
When you need to use a different device for a while, turn off auto.
If it's helpful, please use it, and I'll consider any additional feature requests!
