No sound if PIE [Linux]

Hi, I to play sound on Linux. the problem is that it only plays when I play in a stand alone lunch, not in PIE.

When I lunch PIE, i hear the starting sound of the editor but nothing ingame.

I am on Mint 17.2


stupid question but is the sound turned on in the editor

yes he is.
not a stupid question, the easiest things always catch you :smiley:

[Update] today I realised that the sound even in a standalone version doesn’t play.

I am really sorry… I said that I verified the sound settings… i did NOT. under the settings tab there is a “realtime audio” slider… he was on 0%

Thank you!
