dmix - Enable auto format detection as default

Browse source 
The direct plugins have the automatic format-detection feature but it
wasn't enabled properly in the interface.  Now you can pass the format
"unchanged" to make the plugin detect a proper format.

This will change the default format of some drivers, such as, HD-audio.
