[alsa-devel] iMX ASRC

Hi,

now after the SAI MCLK has been enabled on the iMX6UL in the mainstream 
kernel I'm having difficulties getting the ASRC work.
The default pcm device is the SAI-codec link. That if used does not 
activate the ASRC.
If I use the second pcm device the error message "fsl-sai 202c000.sai: 
isr: Transmit underrun detected" repeats forever.
In /proc/asound only the HiFi-ASRC-FE is present  and not the HiFi-ASRC-BE.

Any idea how to get it working and/or how to debug this?

Thanks!
Petr
