How do you correlate SQL Database Audit spec's log column transaction_id with a LSN? from trans log or CDC capture table?

How do you correlate SQL Database Audit log column "transaction_id" with a LSN either from the trans log or a CDC capture table?I am trying to do this because cdc only captures the data changes, while SQL Audit captures the who, when and what made the change. I am trying to correlate the two.thx~j
