That part works fine. Now I=B4d like to have some way to modify the w= ay to give some parameters to the plugin to tell it how the processing is d= one (eg. set delay time, pan, attack time, ...). = I=B4ve searched the web for days and hours, but could not really find somet= hing. = On the alsa mailing list there was a similiar question three years ago, and= the answer was, that one could create user-space control elements in the p= lugin. How is that done? I could not find examples or good documentation ab= out it. Did I miss something out? Can anyone give me a hint, maybe a link t= o some docs about it or source of a PCM plugin creating/using user space co= ntrol elements? Thanks a lot.
