Lenovo Z51 audio problems?

I bought a z51 couple months back, the laptop is great but i'm having audio issues. MY audio is fine when its from one source, no issues however when there are 2 or more sources f audio only 1 works properly and the others are have really low volume and the quality goes really bad. This is inconsistent, sometimes it works fine with 2 audio sources, but most of the time it messes up.

So you expect one audio chip to handle two audio streams equally and keep them the same quality and volume when outputting to one destination? What planet are you from?
