Basically what we do in hsw_audio_codec_enable() should trigger an irq in the audio driver to, well, whatever it needs to do. It works for HSW/BDW, I don't see why not for SKL. I didn't spot any changes in the audio programming sequence in bspec, so my conclusion is that the audio driver needs to be checked. (And indeed we've already pointed out the powerwell enabling/disabling missing for SKL.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
