Subject: AVPlay Black Screen (Audio Only) on UN50AU7700GXZD (FW 2220.9

Hello,

I’m facing an issue with webapis.avplay on a Samsung UN50AU7700GXZD TV with the latest firmware (T-KSU2EUA-2220.9, likely Tizen 6.0).

When playing HLS streams, audio works fine, but the video screen remains black. Crucially, this also happens with standard public, non-DRM HLS test streams (like Big Buck Bunny: https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8).

The onerror listener is never triggered, and console logs show prepareAsync and play succeed. Firmware is confirmed up-to-date. Testing without setDisplayRect or with different values didn’t help. Basic config/CSS seems fine.

This strongly points to a platform-specific bug (T-KSU2EUA / Tizen 6.0) affecting AVPlay video rendering.

Is this a known issue? Are there any known workarounds?

Thanks for any help.
