Jeza informed us LordJarhead released update 3 for his J.S.R.S. Soundmod on the BI forums.
This small patch will update the script config to support ACR, CWR², CWR² UK and CWR² NL as well as a fix for the SMAW spotting rounds.
We have also updated our download of the full version, so if you have not yet downloaded the J.S.R.S. Soundmod you can just download the full version and you will not need any additional fixes.

Additionally LordJarhead released the J.S.R.S. Soundmod - ACR DLC Sounds which adds the ACR Weapon and Vehicle Sounds. This requires you have J.S.R.S. Soundmod v1.5 update 3 installed!
