[alsa-devel] pcm prepare

Hi,

I am quite surprised that by sending hardware params with alsa-lib the prepare function is called automatically in the driver.

In my case, I would like to open and configure pcmNp and pcmNc and then call prepare for pcmNp and pcmPc channels.

It is quite imperative to execute specific configuration steps after both channels are opened and configured.

I was wondering if there is any ioctl interface that can be hooked in alsa-lib to pass extra configuration info before start the streams.

Any ideas?
