Trying to read a log file encrypted by TDE

I have a full chain of full backups and log backups. I am looking to investigate exactly what transaction was done by a certain user in a given period of time. The database (thus all backups) are encrypted by TDE. Tools such as ApexSQL Log does not work on TDE-encrypted data source. Is there any way I can analyze the log file to find out the information I want? I can run fn_dump_dblog which gives me some information, however I cannot retrieve the exact information on what was changed, such as what column was changed to what value.
