Error: Cannot find path "general.mics.[0].mu.[0]" when running odaslive

[Nikhat-ux]

Description:
When running odaslive with a ReSpeaker 4-Mic Array, I encounter the following error:
Cannot find path "general.mics.[0].mu.[0]" in config file "/home/nikhat/odas/config/odas.cfg

Steps to Reproduce:

1. Built ODAS using the latest master branch.
2. Configured odas.cfg as per the ReSpeaker 4-Mic Array setup.
3. Ran the following command: ./odaslive -c /home/nikhat/odas/config/odas.cfg

Expected Behavior:
ODAS should start without errors and process audio input.

Actual Behavior:
It fails with the above error.

Environment:
