nRF5340 Audio Board Configuration for Unicast Client (Gateway) and Unicast Server (Headset) with Bidirectional Audio Communication

"I'm trying to set up two nRF5340 Audio boards - one as a unicast client (gateway) and the other as a unicast server (headset). However, I'm encountering errors with my prj.conf configurations. Here's what I'm looking to understand:
  1. What are the essential Kconfig options I need to set in prj.conf for the unicast client (gateway) board?
  2. What are the essential Kconfig options for the unicast server (headset) board?
  3. Are there any specific build flags or options I should use for each board?
  4. I'm particularly interested in setting up bidirectional audio communication. How can I enable this in the configurations?
For context, I'm using the nRF Connect SDK version v2.7.0.
Any guidance on the correct configuration approach for each board and common pitfalls to avoid would be greatly appreciated. Thank you!"
