If I create a mixer control using snd_kcontrol. When two applications in parallel try to create a stream and change the snd_kcontrol, can you help me understand how I would get the stream type stored in each substream as a flag?

Also, when I get a snd_kcontrol's .set function call, I am not sure how to get the substream specific data in that call?
