Hi, on my Intel Compute Stick STCK1 (baytrail hdmi audio) sound is not working with the kernel 5.6
I have bisected the kernel and I found the commit that introduced the issue:
commit 58d124ea2739e1440ddd743d46c470fe724aca9a Author: Maarten Lankhorst maarten.lankhorst@linux.intel.com Date: Thu Oct 31 12:26:04 2019 +0100
drm/i915: Complete crtc hw/uapi split, v6.Now that we separated everything into uapi and hw, it's time to make the split definitive. Remove the union and make a copy of the hw state on modeset and fastset. Color blobs are copied in crtc atomic_check(), right before color management is checked.
If more information is required please let me know.
Should hopefully be fixed with commit 2bdd4c28baff ("drm/i915/display: Fix mode private_flags comparison at atomic_check")
Stable folks, please pick that up for 5.6.x stable releases.
