EA QV TeamHi @SymphonyXYZ and @WitnessedJarl and thank you for the reports.
We've tested this today using a full Bad Batch squad in conquest but were unable to reproduce what you've described. Can you record this as a video with sound and provide us with it, please, so that we can get a better understanding? Thanks!
This is super easy to replicate. Just use an aoe from any of the bad batch, wither you use them on offense or they use an aoe on defense. The sound will then continue to play once you finish the battle.
Going to the store and purchasing bronzium card will clear up the issue for awhile.
