Default Poor soundcard?

Lately I've noticed that there seems to be a kind of crossover distortion added to my setup.
Initially I thought it was because of my class BC amplifier (which is an industrial amplifier but has a very beautiful sound with my DM310's :3) but then I noticed that it's only present with my laptop plugged in. not with phone, turntable, CD or tuner.
Then I noticed with my headphones (AKG K142HD) that the laptop really has this distortion in it's signal on certain songs, and the amplifier was simply amplifying the distortion that it was fed.
Is there a way to kill it? It's there with every music player, Spotify, VLC, Windows Media Player, Foobar2k, you name it.
Sound card is Conextant Smart Audio HD or something like that. Laptop is Lenovo T420.
I'm planning on buying an ebay DAC kit but meanwhile I have to get by with this.

It's probably not easily fixable, it's likely a hardware fault on the mobo.

Or just a chip with poor performance?
Machine is still under warranty, I wonder if they'd fix that.

If it's still under warranty by all means take it in for service, it might be just the tip of the iceberg with this mobo.

I haven't experienced any other anomalies with this mobo, even tho this laptop gets beaten around like crazy since it's my main workhorse. (I7 with 8 gigs of memory and dedicated graphics )
Only problem I've had with it was CPU temperature throttling, which was fixed by a re-paste and cleaning
I guess I'll take it in for repairs then. I LOVE Lenovo's service, everything gets done fast, no questions asked

One quick check you can do is to unplug the laptop's power cord (sending it to battery power) and then check to see if the distortion has changed or gone.
