No sound from computer when in Ableton

[DaxPG]

When playing around with the soundsettings because i wanted to "DJ" Use my Headphones and my speakers seperately... Now i don't know what i did, but somehow I only have sound in either Ableton or my computer.I sometimes don't even have sound in Ableton.

Ok. I checked my Asio4all driver and it seems that my Realtek HD audio output is unavailable. It might be in use by something else or there is something wrong with my MS (something) synth wavetable.

(new edit)

Apparantly if i disable all of the playback devices i have all sound back in Ableton. But nothing when i start a song in winamp or youtube. Is there any way to fix that?

[DaxPG]

Yeah. I guess you're right. It was just very handy that i could watch the tutorial and then do it in ableton. But i actually found out that when i plug in my headphones, i can actually assign ableton to go to my headphones and the computer itself to the speakers. Not excactly what i wanted but hey, it works.

Thanks dude
