Hi Jukka, thanks a lot for your response. Good to know about this issue and that there are some other users of WM8510 out there. Unfortunately, for me your patch didn't make any difference. I still don't get sound. Probably there is still something else I'm missing, maybe on the SoC side. The mclk to the codec is ok and I double checked all my devicetree settings, but still no luck.
