imx playback of sound is working on Android 7.1 but I see errors in log

I am getting sound playback fine through the ti codec I have connected, however I see many occurrences of the following error in the logs:

```

```

I will do some more digging on this but any theories?

Hello,

Unfortunately, we cannot provide you support for that type of problem. I apologize for this inconvenient. For that, I recommend you to go with the person who provided you the codec and the driver.

Best Regards,

Diego.

this appears to be occurring in pcm_write_wrapper in tinyalsa_hal.c on the first write attempt but the write is attempted again and succeeds?
