Thanks! I only understood later that icecast does not necessarily have to be in the hassio docker so I installed it next to it and it works!
BUT I notice that the audio stream from icecast is very behind, sometimes 2 minutes behind. Anyone have an idea what could be the cause of this? is it maybe a hardware performace thing?
I have hassio running in Virtualbox with 2 cores, 2gb RAM but it has a hard time with FFMPEG and FFMPEG_NOISE
Is there something I can tweak, do I need to upgrade my hardware or is a two minute delay normal?
