What would be really helpful would be if snd_mixer_open() took an optional pcm handle, and then only returned the mixer controls that affects the signal path of that pcm.
This will be solved by another mechanism like ucm (use case manager). The idea is to return the PCM handle and associated mixer controls (master + pcm) for specified use case (like hdmi output etc.).
