Re: Mixer control names out of control?

[Peter Christensen <peter@developers.dk>]

Oh, I didn't know that about SPSA, but it does make quite some sence, as I don't see why one would have volume control on IEC958 :p. But wouldn't it 
then be more correct to use an enumerated control instead of integer?

But as of simple mixer element vs. kernel mixer controls, I am fully aware, that they are not the same thing. However, the simple elements are 
generated by the ALSA library based on the names of the mixer controls. But the library basically only recognized the names listed in 
Documentation/ControlNames.txt when it sorts the simple elements, which means that elements such as Front, Rear and Side are placed almost last on my 
Aureon card, between lots of unrelated elements.
It would be nice if the library did so good a sort, so that you would have the master playback volumes together 
(Master,Front,Rear,Side,Center,LFE,Surround, etc.), the source volumes together (PCM,Wave,Line,CD,Mic,Aux,Phone,AC97,Video,PC Speaker, etc.), and the 
IEC958 controls together. And it would be very nice if the simple mixer API had a fuction to tell wether the element was actually read-only. The 
ICE1724 driver have some sort VU meter or something, which the simple mixers think are ordinary volume controls, although they're read-only.
