sound output loosing volume!

[sonic_emperor]

,i play my music with mediaplayer,and change track,and cant hear anything and then realise that sound volume decreased for unknown reason at least 70%!and all places where i can increase volume are allready on the max,and i have a feeling that since last two clean installs general volume output has decreased---like before that it would be ok for me to listen music (all on the max on the comp) and -38db on my sony stereo,now for the same level i need -32db...can it be that i should buy a new souncard,now i have onboard soundmax or something similar . (asus a7v8x-x)

and to make it all normal again,i need to restart my computer!

I have onboard and it never does that to me, so I have no idea. Did you try different programs?

[sonic_emperor]

yes...al the players and same thing

i updated bios and soundmax drivers
as this doesnt happen always,i wont be able to tell if it worked/fixed,but ill give it a week time....
if someone gets any idea what was that,or any other info,pleas post...
