One nice day I decided to play World of Tanks, but as the match started I noticed I could not hear my tank(I normally do) unless I got too close to it or enter sniper view.
A similar problem was encountered in War Thunder, but A bit more serious. I can't hear the engine nor the gun firing on tanks unless if I enter sniper mode(Actually they can be heard, but very faintly). in aircraft I can hear the engines, but again, guns can only be heard very faintly, but when in first person mode if I turn the camera left and right I can hear them from the left or right speakers respectively
I run a youtube 5.1 surround sound test video
this one Dts 5.1 Surround Sound Test HD - YouTube
the results are as follows
Initial individual speaker test
front right/left and center speakers worked as displayed, but rear speakers were toned down while front left/right speakers did the main work. Subwoofer was not even heard.
At 2:22 front left/right are supposed to be heard. the sound comes from the rear speakers.
At 2:54 only the two rear speakers are heard. the next test is heard from the front speakers.
Only 3:10 sounded right.
Also in the Realtek sound management panel when I test the speakers, only the front left/right speakers work.
center speaker works with all sounds in games except the afforementioned. The system is set to PLII Movie effect. Checked levels and wires for all speakers and audio jack connections. All are seemingly fine.
