BLE Hearing Aid Support (LC3 codec?)
Streaming audio from a Bluetooth source to a hearing aid is a feature incorporated by recent hearing aids. As miniaturized devices, they use BLE codecs.
Some Android vendors (Samsung, OnePlus, Google, Apple...) implement this capability. It is my understanding that the Hearing Aid industry is heading towards the LC3 codec, as it can be seen here: https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=502107&vId=542963 (codec specification).
An Apache 2.0 licensed implementation of said code is available here: https://github.com/zephyrproject-rtos/liblc3codec
So... What would it take to implement Hearing Aid Bluetooth streaming into pipewire? Would this be an unreasonable effort, or would this be matter of simply implementing an LC3 codec?
I do own one of these hearing aids (which are sort of a niche and expensive devices), so I'm more than willing to help with this.
