HDMI no audio @4K above 60Hz

[adolfotregosa]

It as been an issue since driver 465.

With latest driver @4k we lose audio when refresh rate is above 60Hz.

TrueHD, Eac3 or PCM? What about 192k 24 bit PCM? Does that work? What about 20 bit, yep it does exist?

Nothing. No audio comes out @4k with refresh rate above 60Hz

Thank you adolfotregose for your report. I believe this one is already tracked internally as bug 200761422, and we are actively investigating the issue. As I understand it, it is not specific to the GSP driver architecture.

I have linked this issue with our internal tracker so the engineers working on it can reach out if needed.

A fix has been identified and is in test. It will be integrated into a future (including this repo) driver release.
