USAC (xHE-AAC) 5.1 Linux Playback

Hi. I am using exhale for encoding. Previously I encoded only stereo and played it with ffmpeg (compiled with libfdk_aac support) or with foobar2000 through Wine. And today I decided to encode a fragment of a 6-channel audio track from a movie. The encoding was successful. But I found that libfdk can't play multichannel audio. Is there any USAC multichannel decoder for Linux or for Windows (working through Wine)?

Thank you, that makes sense now.
It seems that for multichannel audio I need an encoder and a decoder with MPEG-H standard support. There is a free decoder from Fraunhofer IIS for playback, but no free tools to encode it.
Opus will probably remain the best choice for multichannel audio available to the average user for a long time to come.
