--- Comment #26 from Alan Swanson <reiver@improbability.net> ---
Still an issue with Linux 4.12.3 and radeon driver where passthrough of Dolby
TrueHD or DTS-HD MA at modes lower than 60Hz results in no audio signal
reported by AV amplifiers.

While can at least decode both to raw PCM output in Kodi by disabling
passthrough  it would still be nice to fix bug and offload the processing to AV
amplifier.

kernel 4.15.rc8 log with drm.debug=0xe and non-working dts-hd

Hello

Unfortunately, DTS_HD still does not owrk with kernel 4.1.5.rc8. 

I've attached a complete kernel log done with drm.debug=0xe

While playing (silently) a DTS_HD file with kodi, the kernel logged a lot of
lines like:
 [drm:radeon_crtc_page_flip_target [radeon]] flip-ioctl() cur_rbo =
0000000026ca5fac, new_rbo = 00000000696c7c9c

Is this log enough to progress or do you need more logs with other debug
parameters ?

All the best
