Please follow the control naming standard in ControlNames.txt: all volume controls must have Volume as the last word in the name.
Thanks for this information. I would suggest "Right Fine Playback Volume". Where "Right" is the "CHANNEL" from ControlNames.txt. However, there is no "Right" in the "CHANNEL" section. What do you think?
.name = "wm8741", .playback = { .stream_name = "Playback",
.channels_min = 2, /* Mono modes not yet supported */
.channels_max = 2,.channels_min = 1,
This should be varying with the platform data: in the mono modes we can't do stereo and I suspect the stereo modes may have issues with mono.
I think this should be always ".channels_min = 2". In "mono mode" the DAC plays either the right or the left channel, however the I2S signal is expected to be stereo.
