So I just did my usual checks for any updates to the Ally and found both 1 from AC and a separate one for Dolby Atmos. Previously, I get good volume with Atmos at just 50% volume, but after a previous round of Ally updates, some games just have terrible sound volume with Atmos enabled and checking this sub, it appears to be a common issue after that update.

For example, P3R has been absolutely terrible with Atmos enabled even with 100% volume. You can barely hear anything coming out from the speakers. Turning Atmos off, I get good volume at 50% but it just isn't the same as with Atmos enabled and working correctly.

Now with everything updated including Atmos, I tested out P3R with Atmos enabled and got back the old Atmos loudness even at just 50% volume, which is louder than 50% with Atmos off, as it should be.
