Hello
I have a problem with my notebook. When I power my device everything is fine, but after ... let's several minutes sound disappears. The strange thing is that "mute button" on my keyborad is not responding too, when I hit it theres no orange light and one the screen appears a lvl of volume ( normaly it should be a crossed volume lvl). When I want to play Spotify or something like that it says that my Audio card is used by another program... The funny thing is that when I did something like "stress test" (I played Spotify when sound worked just after system start) sound was working for about 6 hours and everything was fine. I hope I'll find any kind of soution here.
System: Windows 8
Model: Notebook HP Pavilion g6-2310sw
Also I'd like to add that every system restart fixes that problem but only for a while (several minutes).
