Hi @thansen_dk

Thanks for the reply. I do agree that we should keep this post focused on @talentles’ problem, so I’ll keep the response here brief.

I’m glad this fixes the playback issue for you. You can add these commands to /etc/rc.local

cat /sys/class/amhdmitx/amhdmitx0/disp_cap > /tmp/disp_cap
cat /sys/class/amhdmitx/amhdmitx0/aud_cap > /tmp/aud_cap
cat /sys/class/amhdmitx/amhdmitx0/edid > /tmp/edid
sudo mount --bind /tmp/disp_cap /sys/class/amhdmitx/amhdmitx0/disp_cap
sudo mount --bind /tmp/aud_cap /sys/class/amhdmitx/amhdmitx0/aud_cap
sudo mount --bind /tmp/edid /sys/class/amhdmitx/amhdmitx0/edid

Before exit 0 as a bit of a hack for now. It confirms that when the refresh rate changes, the capabilities are not available via sysfs so there are problems with configuring sound. The suggestion above won’t cause any adverse affect, so until I find a way to work around this situation for you, it should work fine.
