I still think these are poor choices for mixer control names. The kX driver solves this problem nicely by separating the AC97 mixer controls from the ones implemented with EMU10K1 DSP microcode. I guess to have this option on Linux, we'd need some way for driver to report which controls are part of the AC97 codec.
