Title: JRSS Mixing - 7.1 > 5.1 W "Extra Channels" Not Working Properly?
Post by: whoareyou on April 01, 2024, 09:54:58 pm

A while back, the following thread discussed a 5.1 w/ 2 extra channel configuration, and that JRSS did not properly down mix
the audio.
https://yabb.jriver.com/interact/index.php/topic,134347.msg930486.html#msg930486 (https://yabb.jriver.com/interact/index.php/topic,134347.msg930486.html#msg930486)

The last post in this thread says this was fixed, but it seems this is still an issue because this configuration still displays "Convert From 7.1 Channels To 7.1 Channels" instead of "Convert from 7.1 to 5.1"

It sure seems like JRSS should be downmixing this, and there should be 2 extra channels somewhere.

BTW - If you turn on the newish option to use the new channel mapping system, then nothing is displayed regarding what is going on.
 
So is this all working as expected or is this still an issue?

appears to be mixing as expected to me, can you post a sample to show exactly what you think is wrong?

Images showing Audio Path with and without 2 extra channels.  Only difference between the two is the 2 extra channels.
Playing back a 7.1 bluray backup by MKV.

Also, when selecting the "new extra channels system" Audio Path does not show a conversion at all when 2 extra channels are added.

Is this how you think it should work?

I didn't look at audio path, I just measured the actual output (which seems correct). The audio path info certainly looks wrong so that seems like a bug.

I'll try to make this better using the new system tomorrow.  Testing appreciated once it's out.  Thanks.

Still a bit confused with the old system.

Is the old system's 7.1 -> 7.1 notation correct, but it's really being downmixed?  I can check it out later, but not at my machine at moment, so if anyone knows the answer, I'd appreciate.

Thanks.

I already said it's mixing as expected as far as I can see

Sorry, missed that somehow.  Thanks.
