Hi there,
I’ve recently started using a Bluetooth speaker with my system and have noticed that, while the speaker stays connected, whenever audio is resumed after a pause in audio playback there is a short delay until audio starts playing. It is reminding me of the power saving feature in Pipewire that was causing the same issue with analog audio until I commented out suspend-node in /etc/pipewire/media-session.d. While that fixed the issues with my analog audio, it did not fix the issue for Bluetooth. Does anyone know of a way to disable the power saving for Bluetooth?
Thanks
