Device yellow in Aneman - Too many streams of 2 channels or less.

Problem

In Aneman 1.3.3 (or above), your Horus or Hapi 1 device turns yellow.
The error message displayed is Too many streams of 2 channels or less

Solution

The Horus – Hapi 1 are optimized for 8 channels streams, but not for mono or stereo streams. 
Usually, a single stereo stream can be used (Headphones for example), but depending of the sampling rate, additional mono or streams may cause drops in the audio (reflected by “Ethernet input” errors on the device. 
In such case, please use 8 channels streams. 
Anubis and Hapi MKII are not subject to this issue.
