The mono mode of the device should not be confused with the ALSA mono mode. If the device is in mono mode it either plays the left (mono left mode) or the right (mono right mode) channel.
My board has two of this DACs (left and right channel). The control names should be different, hence my suggestion for the "Left" and "Right" prefixes.
That's fine and totally normal.
Another approach would be to say that the machine driver is responsible for mixer controls if the devices are in mono mode. What do you think?
Yes, the machine driver should do this - you may have left and right on your board but these configurations are for example often used with 5.1 systems.
Good point. Thanks. I am going to resend the patch as v2.
