Audio Problems

I noticed that when the volume is turned down, it decreases most of the in-game volume stuff. EXCEPT for the bleeps and bloops when a turn ends, which remains at max volume. Because i run music in the background, or play with headphones, or run skype at the same time, I need the volume of everything lower so that i can hear what's going on. But the blaring beeps when i end my turn, at full volume, are hurting my poor ears.

So could it be possible to make it so that the volume of the end of turn noises is affected when the audio setting volume is diminished? Thanks
