Will there be ay problem in using front audio port while using USB speakers?

I'm planning to buy Lenovo M0520 2.0 Speaker, its a usb powered speaker.
will there's any problem in using a headphone connected to the front audio port. As I heard the usb speakers interfere with the systems sound card and the front audio port won't work. Is it true?

Well that's the good thing about USB. When you are using the front headphone socket on headphones just UNPLUG the USB speakers (You aren't using them when on headphones). When you are finished plug them in again!

Tara easy wasn't it!

I personally don't own the product mentioned but I can mention what I have heard.
I have heard that there's a massive problem with the systems sound card and multiple people complain about it via comments or reviews.
I would stay away if you are planning to use headphones
