[alsa-devel] WM8510 on i.MX6

[Schrempf Frieder]

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.

Thanks,
Frieder
