[IMX8MP] Audio playback clock issues

[MrNam]

Hi,

I am having some problems playing audio on a custom i.MX8MP Board. I can play some audio files just fine, but for others I get a kernel error like this:

failed to derive required Tx rate: 1411200

Depending on what audio file I play, the Tx rate is different. For example (audiofiles are in attached zip file):

aplay test.wav #works, clock: 1536000

aplay test_tone.wav #does not work, "failed to derive required Tx rate: 1411200"

aplay phone.wav #does not work, "failed to derive required Tx rate: 352800"

Could someone please have a look at my device tree and tell me where the problem might be?
