Philips Titan OS 8 channel audio playback issues

[geomusicmaker 4]

I've come up against an issue which I think is tied to the fact the app is running in a web wrapper. On films with 8 channel audio the app produces no sound. Regardless of audio codec, anything 8 channel is silent.

When I play the same films via DLNA using the TV's built in video player the audio works. I think whatever browser version the app is utilising doesn't have the appropriate codecs or capabilities to support 8 channel audio.

Would it be possible to add a "force downmix to 2.0/5.1" function to the app so this can be mitigated?

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

Hi, here's a bunch of logs where the audio does and doesn't work via the Emby app and DLNA.

In testing this particular film I tried going through the playback correction wizard (not captured in the logs). This transcodes the file to 1080p and the audio does work after this, but it degrades the quality of the file and I'd much rather play direct (especially seeing as it's a 4k HDR). Annoyingly having applied playback correction to this file it seems to now default to that playback setting and I have to change the quality manually every time I want to play direct.

What is your tv connected to for audio output?

[geomusicmaker 4]

I've tested it using an external HDMI audio device, a headphone jack based device, an optical out device and the TV's own speakers. It's to do with it handling the audio track. As I say, the same file on the same audio device (all three of them) will play sound when using DLNA, just not through the app.

Can't seem to edit my previous post so for clarity, regardless of audio device, the same file has sound when played back via DLNA and my firestick. It only loses sound when played through the app for Titan OS except when transcoding.

Is the only way for an Emby app to exist on the platform through the Opera web engine? The TV's built in video player seemingly has better compatibility.

This is the only way that Titan is providing right now.
