**UPDATE - New Audio Engine Activated Again!** - We're back again this week with the New Augio Engine. We've fixed a lot of the issues you mentioned from the last test, but still need your help! Please post any audio issues you come across below so we can make sure they get fixed.
For the next few days or so we'll be turning on our new audio engine again for another round of testing on the PBE! With each patch we are getting a little bit closer to activating the new audio engine, and we want to continue PBE testing to ensure the switch goes smoothly!
If you find a sound that doesn't work, or if you want to leave feedback about the way things sound, just leave a comment on this thread! We’ll be actively monitoring it and replying to your questions and concerns. Please let us know what equipment you’re using for audio (Stereo headphones vs. 5.1 surround sound speakers, Sound Blast Zx vs. Realtek HD Audio) so we can help narrow down the cause of the issues.
If you’re unsure how to get that your system info, here’s a handy guide for [PC](https://support.leagueoflegends.com/entries/27495980-Network-System-and-League-of-Legends-Logs#wq5) and one for [Mac](https://support.leagueoflegends.com/entries/27495980-Network-System-and-League-of-Legends-Logs#mq4).
**Why are we changing audio engines?** We’re looking to create a more immersive and engaging in-game league of legends audio experience, and this new engine will allow us to do a lot of cool things in the future.
