So, this came from a review comment from me in response to a patch doing just that. The issue I had was that this definition of overlapping ranges really feels like the kernel is bodging around limitations of the userspace library - the library is already trying to find the best match among the actual dB values available, it seems silly that it requires the kernel to provide patches between the ranges. It's moderately painful, especially if you have a bunch of values that aren't very well joined together in the hardware. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
