There should be a sound when you selected a Relic lying on the ground before.
Now when you select it, there is no sound most of the time.
Both during the game, in the replays and when observing a match.
Sometimes when you try selecting it again, the sound plays, but then disappears again. You can click on a Relic multiple times, a few times the sound will play, then it will stop playing on selecting a Relic again.
When you select a Wolf, its barking sound is still being played.
