I am writing this mixer app:
I have trouble with callbacks. So far I have implemented callbacks for
the master volume fader and clock rate selection (integer and enum,
But "pad" callbacks (boolean) won't work. In fact, I have noticed that
alsamixer 1.0.22 also doesn't react to pad changes from the application.
But the driver reacts to both as expected, so we're dealing with the
I set callbacks with this:
And periodically poll them with:
if (snd_hctl_wait(hctl, 10))
As I said, integers and enums I have tried so far, work.
Thanks for any help,
