Never mind, it works now. I understand that the DAPM controls need to be
enabled for the clocks to actually run, as described here:
On the #alsa-soc, I was told that I could force on the control in my
machine driver. Specifically, I was told this:
"in your board file you can always make an always on output in the DAPM map"
Can you tell me how to do this? Is there an example? I don't want to
have to rely on user-space configuration to get playback to work.
