Manjaro - Impossible d’utiliser mon micro de mon casque bluetooth
Après le son, voila que je n’arrivais pas à utiliser le micro de mon casque bluetooth.
Après moult recherches et tests, j’ai enfin trouvé. En fait, Manjaro (ou le kernel ou je sais pas quoi) ne sait pas permuter automatiquement entre le mode HSP / HFP (qualité médiocre, mais micro et son fonctionnent) et le mode A2DP Sink (très bonne qualité, pour écouter de la musique).
Alors, OK, macOS tout ça, tout ce qu’on veut hein. Mais on branche ou on connecte et ça marche. Juste ça. Bref.
J’ai trouvé un script (ici) que j’ai adapté et que je partage ci-dessous. Il permet donc de permuter très facilement entre ces deux modes.
