What changed in this PR
This PR initializes a low-latency (LL) task for DP-only audio pipelines during preparation, enabling secondary-buffer synchronization before DP processing.
Changes:
- Removes the LL processing-domain restriction on task initialization while preserving error handling.
- Adds documentation explaining why DP pipelines need LL scheduling for triggers and buffer synchronization.
