Debugging 'sdu_ref_us not from consecutive frames' Issue with Samsung S23

Hi,

I am currently encountering an issue with the error message 'sdu_ref_us not from consecutive frames' in the following scenario:

  • Broadcasting Source: A Samsung S23 device starts broadcasting audio.
  • Two ADKs are involved:
    • ADK#1: Syncs audio from the beginning and operates without any issues.
    • ADK#2: Begins syncing approximately 11 minutes after broadcasting starts and reports numerous 'sdu_ref_us not from consecutive frames' messages.

This behavior persists even after rebooting the devices.

I would greatly appreciate your guidance in understanding why this issue occurs with ADK#2.

Thank you in advance for your time and assistance.

Please let me know if additional information or logs would be helpful.

Attachment: Logs from ADK#2 for reference.
