+1 for 16 channels. We often put foreign tracks on channels 3 and up and in few cases needed more than 8 channels.

It would be super brilliant to get rid of STEREO as default values for all audio layouts, setting everything to 16ch/passthrough.

2.2 or even 2.1? I can't see any reason why not.

@jesperstarkar 8 channels passthrough, yes

ffmpeg doesn't support 16 channels as far as I know at the moment. So adding 16 channel support is going to be difficult.

Oh yes it does!

CCG 2.1.0.3440 beta2 and my own custom client test panel.

16channels

It seems not to work with a 16-track mono-channels file, so all 16 channels need to be in one single track.
However it does work with an 8-track mono-channels file, it play all 8 tracks.

i prefer having as much channels as possible as a default
if 16 is hard to make then 8 would be nice

It will be 8 channels.

It will be 8 channels.

Does that mean that all 16-channel capabilities will be removed/disabled/or not working? If 16ch is an option, and it is as shown above, why go for 8 and not 16/passthrough?

We're going with 8 channels for this release. We can increase to 16 channels in a future release.

There is a significant difference in terms of development between the two. We need to get to the finish line at some point for a stable release. Sorry.

@ronag that's understandable. Thank you for your good work! :smiley:

+1 for 16 channel audio

Here we are almost 2 years later. @ronag @dotarmin any update on this? We do foreign tracks and need to be able to use 16 channels. It's a deal breaker for me. (Having to fall back to EVS for now.)

+1 16 channel audio would be great!
