Hi, for a raspberry pi i2s audio addon we use this snippet in the asoundrc: pcm.micboost { type route slave.pcm dsnoop ttable { 0.0 30.0 1.1 30.0 } } The hardware has no mixer. Now we'd like to make the "30.0" a value to be exposed as a control, so that e.g. alsamixer would show it. If seen that there is a control { } block, but I can't find docs for it. Any pointers.
