In essence, recent package from Maxima nearby (supermarket, mall) –
BT 4.1 headphones are missing recognition criteria for some apps (at least War Thunder on SteamOS). The game is installed, launching in a OpenGL window, working video, playable and so one, but no sound, a pity. It can play via laptop speakers, but it’s no fun.
BT headphones can be used by Spotify Chrome app, Skype web app etc, but no actual play sound of the SteamOS game. Bad blood? Mal-recognition? It was a more or less standard package in tech section of the mall, nothing special nor spectacular. Hopefully, BT cards will be more adjustable to home appliance gadgets like non custom order BT headphones.
