Okay, new update that I think explains why it sometimes worked and sometimes didn't: When starting playing audio and then connecting the monitor, I don't hear any sounds from a real monitor. When first connecting the real monitor and then playing audio, I hear it. The IGT test first starts playing audio then connects the monitor. * * * Summary: I believe this is a real driver issue. I don't know whether this is a bug in the audio stack or in i915. User impact: mini-DP audio doesn't work if the user started playing audio before connecting an external monitor.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
