Description

Export all mixer nodes into dev.pcm.X.mixer.Y sysctl nodes, hence the
PCM API doesn't support showing all the knobs. Make sure all the USB audio
mixer nodes are freed at detach. Before this patch USB audio would leak
some memory at detach. Print out buffer sizes in number of samples at attach.
Fix setting of volume controls when the number of channels is greater than two.
