[alsa-devel] Testing SAI with mainline

Hi,

I am trying to get SAI to work on a mx6sx sdb board.

Here are the changes I made: http://pastebin.com/aq32B24v

I can see the driver getting probed:

[ 2.198276] fsl-asoc-card sound: wm8962 <-> 21d4000.sai mapping ok

,but when attempting a playback it fails:

$ aplay clarinet.wav [ 110.843619] fsl-sai 21d4000.sai: isr: Transmit underrun detected [ 110.849841] fsl-sai 21d4000.sai: isr: Transmit underrun detected [ 110.855995] fsl-sai 21d4000.sai: isr: Transmit underrun detected

(repeats forever).

Any ideas as to how to get SAI working on this platform?

Zidan,

How have you tested SAI when you usptream the driver?

Thanks
