ALSA control core has a feature called as 'user-defined control element set'. This will help your work, in my opinion. For example, alsa-lib 'softvol' PCM plugin utilizes this feature to accomplishment configurable volumes by the others[1]. This feature supports metadata by TLV (Type-Length-Value) and eventing to subscribers as well.
The alsa-lib includes a test program for this feature, which I wrote[2]. This may help your work by its actual code, I think[2].
Many thanks for your prompt reply Takashi! I'll study your example code and report back, should I need further guidance.
