So no two devices with the same control set. That makes sense, and cuts down the choices a bit. Anyway, I thought about the issue for quite a while, and the above point about the KDE/GNONE applets and no duplication of controls just gave me the last pieces of the puzzle: 1. It *is* separate hardware, it has nothing to do with whatever might be the embedded soundcard and codecs, except that it sits between them and the speakers and line-out jacks. 2. It controls more than just the embedded soundcard, it also controls the PC squeaker (independently of the embedded soundcard being able to control that or not), and also the firmware ACPI/APM/alarm beep generator. Therefore, it should go in a different card. That works just fine, it requires no new API in ALSA, it follows the kernel standard for these things (if it is a separate device, export it as a separate device), and it makes a lot more sense from the system's point of view. A non-broken ALSA mixer applet will just let you add itself twice to the applet bar: once to control the thinkpad mixer, and the other to control the embedded soundcard. Or it will allow you to pick your favourite set of controls out of those available from every card in the system. The above makes too much sense. I must have forgotten something, it can't be that simple.
