SET Channel layout AMCP command issue

I’m trying to run the AMCP command SET 1 CHANNEL_LAYOUT Stereo but the server returned a 403 error.
Someone already successfully use this AMCP command ?

Version of server: 2.3.0

Thx.

I think channel layout is not supported. I base this statement on a line in eth changelog.md file at server/CHANGELOG.md at master · CasparCG/server · GitHub where in the General changes for server 2.2 there is a line that states:

Removed channel layout in favor of 8 channel passthrough and FFMPEG audio filters.
