The problem is that this device has only two DACs while there are three outputs (speaker, bass speaker and headphone). So the driver tried to assign front and bass, while sharing the same DAC between the bass and the headphone. Admittedly, this doesn't look ideal assignment. We may assign one volume for both speaker and bass speaker (those are tied), and another for the headphone, too. It's a question of trade-off. I'll check a bit more deeply later. -- You are receiving this mail because: You are on the CC list for the bug.
