[alsa-devel] [Alsa-user] HBR audio not working with radeon/caicos below 60Hz

[Dominique Dumont]

Hello

Unfortunately, I cannot get HBR audio (DTS-HD and dolby TrueHD) on my system 
with all refresh rates. Only 59 and 60 Hz refresh rates are working more or 
less 
properly: there's a dropout every now and then. Refresh rates below that are 
silent: no error is reported by kodi or by the kernel but my yamaha amp does 
not detect the audio stream.

My yamaha amplifier is connected by HDMI to a radeon Caicos card. See [1] for 
the output of alsa-info.sh. DTS, dolby digital and DD-plus are working fine.

This is a known issue [2] for kodi people. A bug [3] was reported on 
freedesktop.org to no avail.

Can this issue be solved by alsa people or is this more an xorg bug ?

Feel free to get back to me if you need more info.

All the best
