[Resent as I don't see the message back; if you already received it,
please disregard this]
another thing I'd like to push into the next kernel is the virtual
master volume control. As I posted in earlier posts, it adds virtual
controls that have several slave controls with the same types,
e.g. Front, Surround, Center, LFE, etc. Then these are adjusted
simultaneously via the master control.
It'd be appreciated if some one can test the patches with HD-audio h/w
that has no master control yet (e.g. some STAC codecs).
Note that this won't add the master volumes if there are no real
volume controls. Some codecs have really no volume control, and this
won't help for such devices.
Two (and one for driver) patches will follow after this.
