Hi Sirs,
Here is chromebook SW team from Compal.
As the mail title, we hit issue that the external monitor will flash once when
play video after hot pluging.
We can reproduce not only on chromebook but also ubuntu 16.04.
There has higher failure rate with Dell Solomon dock and Dell S2718D monitor.We found adding the delay in "sound/pci/hda/patch_hdmi.c " can fix this issue.(as the attachment) May need your help to review and advice. Thanks. Here is the issue number in gitlab for more detail. https://gitlab.freedesktop.org/drm/intel/issues/318 AJ Cheng NID/NID1 e-mail: [email protected]<mailto:[email protected]> Tel: +886-2-8797-8599 ext. 17561 Mobile : +886-932827829 COMPAL Electronics, Inc.
