Speaker sounds cuts + Video Lags

[St1flus]

(Sorry no other place to put this; mods please move if you can find a better place)

I have several audio outputs in my computer.
My speakers, which are on the Green Line Out connected to the motherboard, stops working (I don't know why).

This has happened during live stream viewing and when using ASIO4ALL v2.1 (for FL Studio).

If I switch the default output from the speakers to something else like headset (which is USB) then audio is restored (but only through speakers) and videos stop lagging.

When I switch back to speakers W/O restart then it resumes lagging video and outputting no audio.

Any idea on how to fix this? I'm on Windows 7 x64 and I have an EVGA P55 FTW Motherboard.

~TL;DR: I would like to fix the speaker audio and video lag problem when Speakers are on the default output w/o having to restart everytime.

Updated your drivers recently?

Yeah BIOS is up to date, so is Windows, so are the audio drivers.

Thanks for linking me that forum. I didn't even know it existed... X_X

Update the video drivers.
