Description of the change

• https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/jobs/512750 failed due to expected mismatch in number of output channels between ref and dot. Disabling the tests for the merge and will re-enable them after the merge is done

Affected operating points

• Describe here as well as possible what operating points are affected and how
• In minimum, there should be a status for bitstream compatibility and output bit exactness
• For bitstream compatibility, the following levels are helpful for describing encoder
  1. Produced bitstream is BE compared to previous state.
  2. Produced bitstream is non-BE but it is fully backwards compatible for decoding. Decoded output may differ.
  3. Produced bitstream is non-BC. Old decoder cannot decode the produced bitstream correctly.
• For output difference, use BE or non-BE. Additionally, amount of difference can be presented.
