Did some more testing and don’t know if the latest beta has changed something, but it looks like al the (test) files now have surround sound, but still lacks bass/lfe. So it still sounds a little ‘hollow’ sometimes.
This is a good 5.1.2 channel test to see if the stereo HomePod setup produces fake-surround and to see that they do not play any sound through LFE with Infuse:
Playing the same file through the following apps shows that the LFE is working for the above setup:
Plex app (use old player)
FilebrowserTV app (plays (compatible) files directly from for example your NAS and sends it through the internal ATV player)
Hopes this gives some more information for the devs.
Tested with the AirPods Pro (gen 2) and the same issue: it just lacks bass. Spatial Audio with head-tracking is working, but it just has no bass inside Infuse. Play it through the internal ATV player and there is the bass again.
Strange thing that I am the only one having/noticing it? Am I missing a setting in Infuse maybe?
Another update after I’ve tested with just using the TV speakers:
Any app on the ATV which uses the internal player:
LFE channel is playing a little rumble (wouldn’t call it bass as they are TV speakers but it gives sound)
Infuse: there is just no sound coming from the LFE channel, even on TV speakers it is noticeable.
So clearly I’m missing a setting here or there is something wrong with my infuse/plex server setup, as I cannot imagine no-one is noticing the lack of LFE.
