If the ASP1 DAI is hooked up by the machine driver the ASP TX mixer sources should be initialized to disconnected.
The silicon default is for the mixer source registers to default to a collection of monitoring sources. The problem with this is that it causes the DAPM graph to initialize with the capture path connected to a valid source widget, even though nothing setup a path. When the ASP DAI is connected as a codec-to-codec link this will cause the other codec to power-up even though nothing is using it.
