Not sure what you mean by "compile driver with debug=verbose," supposedly, some kernel ALSA debug parameter. Since this is my driver, I can certainly add any debugging there, but it seems obvious to me, that the kernel is still getting a mono configuration, which shouldn't be the cae. > you can find out how ALSA refine the hw parameters by examing the system log If you mean "dmesg" output, then, as I said, there isn't much to look for there - the kernel is configured for mono...
