LE13 Testing for RK3288, RK3328, RK3399, RK3566, RK3568, RK3576, RK3588

    oke, update - I just tested the latest build (21/02/2026) and audio passthrough of at least Dolby Digital works fine (dts untested); however, with my UHD bd rip streamed from a smb share, I had some severe frame dropping. Multiple frames at a time...

    I will retest with some more time, with passthrough enabled and without...

    What I also noticed, was pcm output seems wrong in regard to channel mapping. The center channel was played by the right channel speaker.

    I've pushed updated RK3588/RK3576 images that appear to have HBR formats "working" to some level now, although I hear some glitches on a few files that could be underruns or some kind of DP/HDMI bandwidth issue.

    I don't see channel mapping issues with speaker-test -D hw:hdmi0,DEV=0 -c 6 on a Rock 5B board. Channel mapping was an issue in the past, but Kwiboo spotted the problem some weeks ago and a fix was submitted upstream.

    If you see issues with SMB shares perhaps experiment with different SMB chunk size values in the Kodi SMB client settings. I see no issues with 50GB+ sized ISO rips (other than start being slower) so that sounds more like an environment or media problem.
