Sorry Mengdong, we haven't looked into this yet. :( Is this still an issue with current upstream or drm-intel-nightly? Hi Jani, This issue can still be reproduced with latest drm-intel-nightly. Nothing in the kernel logs or reg dumps... can you get ahold of an HDMI analyzer and see if we're sending audio frames correctly right away? It might be a problem with this sink somehow. Sounds like you can work around the issue by sending two streams when starting to play new audio? That might be something you could do in the audio driver if this sink is detected. Another try with current drm-intel-nightly would be good too. I think the audio rework on the display side fixed a bunch of odd cases. Hopefully this went away. Please re-open with some more info if not, Mengdong. |
