michael123 Can you let me know if they work after the LSPCon update. I have a Coffeelake setup which just will not work with HBR Audio in Linux but is fine in Windows (Seems quite a few people have this issue). I changed from the internal LSPCon to a new Club3D CAC-1088 on the Displayport but although this is consistent/reliable it still does not work with HBR Bitstream in Linux. Some people have suggested that LE10 has less issues with LSPCons but that is not an option for me.
Seems to work fine, old Sony amp correctly identified Dolby True HD with pass through over HDMI. Running Libreelec 11.0.6 (latest). Gone back to direct to HDMI direct to TV and optical for audio now. Obviously lost out on passthrough/hbr audio (normally 5.1 will do for us) but gained 4k/hdr so swings and roundabouts.
