Hi James,

To get the Kodi log described above, I had to run Kodi with PulseAudio
suspended,
so that it would use ALSA, i.e:

pasuspender -- env KODI_AE_SINK=ALSA kodi

Then exit and look in ~/.kodi/temp/kodi.log for lines like this:

2022-08-14 14:21:59.094 T:11127 INFO <general>:
CAESinkALSA::Initialize - Attempting to open device
"hdmi:CARD=PCH,DEV=0"
2022-08-14 14:21:59.099 T:11127 INFO <general>:
CAESinkALSA::Initialize - Opened device
"hdmi:CARD=PCH,DEV=0,AES0=0x04,AES1=0x82,AES2=0x00,AES3=0x00"

Cheers,
Justin.
