I have Logitech bluetooth adapter connected to my hi-fi system. When I connect to the adapter via Ubuntu's default installed bluetooth, and play some music, I get a really low quality sound. It's not the problem with adapter because when I connect to it from Windows on same PC sound quality is really good. I'm guessing that Ubuntu is using some low audio codec or driver is not adequate for playing sound over bluetooth.
Is there a solution for this kind of a problem? Is there a way to override default bluetooth driver and use something more adequate?
