The WM8960 driver isn't in the standard Linux kernel yet, it is currently distributed via the Wolfson web site. None of the drivers included in the standard Linux kernel were using their dbg() macros, though some had such macros present. > I think, it maybe potential that reduce performance before one knows. The performance impact should be very minor - the digital mute is not used in any hot paths and the output will only go do the dmesg buffer by default so won't have the overhead of writing to the console. Out of interest, which platform are you working with? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
