A reliable, multi-brand hearing-aid/cochlear-implant audio-streaming and pairing tool for Linux PCs, Steam Decks, and standalone adapters (ASHA) instead of being phone-locked or buying vendor accessories
Hearing-aid and cochlear-implant users want to stream audio straight from Linux PCs, Steam Decks, and DIY Bluetooth adapters over the ASHA protocol rather than being tied to a phone or forced to buy the manufacturer's proprietary streaming accessory. Today this works only through fragmented, per-brand, GUI-less developer projects that re-break on every device firmware or OS update, so getting sound requires deep Bluetooth debugging. The opportunity is a reliable, multi-brand, GUI-driven ASHA streaming and pairing layer for an audience whose hearing device is their only audio path and who will pay to never lose it.
The trap is shipping another single-brand hack that dies on the next firmware or BlueZ update; the defensible product is a maintained multi-brand compatibility layer with a real pairing GUI (ideally paired with a certified hardware adapter), because for this audience audio literally stops working without it.

Streaming ASHA audio from anything other than a phone is served only by fragmented, single-maintainer, GUI-less projects plus an experimental mono-only native stack, so each hearing-aid brand and each OS update silently re-breaks audio for users who have no alternative audio path.
