Audio not working linux 4.9

Hi,

 

I've updated to the latest linux 4.9 kernel.

When I now run `aplay -l` it shows:

**** List of PLAYBACK Hardware Devices ****
card 0: rskrza1max9856 [rskrza1-max9856], device 0: MAX9856 max9856-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

 

So this looks nice, but whenI then run `aplay file.wav` I get:

scu playback route is invalid.
scux-pcm-audio scux-pcm-audio.0: ASoC: can't open platform scux-pcm-audio.0: -1
aplay: main:807: audio open error: Operation not permitted

 

It looks to me it has something to do with the Device Tree, but I did re-flash the dtb file.

Am I missing something?

 

Kind regards,

 

Remco Poelstra
