Adau1761 stuttering?

Hello,

I'm using the ADAU1761 codec in my custom board design. I followed all the design guides and wikis to integrate that component, and after a couple of minor software problems (i'm using Yocto Morty release) it's working pretty well.

Sometimes though, like once in more than 20-30 boot ups, the codec is like "stuttering". The audio recorded is full of gaps, and the problem persists unless I re-cycle power supply.

I'm using an external oscillator (exactly as the dev kit), and I cannot find the source of the problem since without modifying anything on the OS the problem pops up, in a completely random fashion.

Attached you can see the behaviour of a recording at 48khz, and the recording itself.

What can be the issue here?

Thanks
