Question Phone as bluetooth stick / bluetooth sharing

Hello XDA!

First, sorry for my bad English, i'm from the Netherlands.

My soundcard is broken (PC). I have a bluetooth headset, but not a bluetooth stick for my PC or something else.

(As you can see, i want to connect my PC to my bluetooth headset)

I was wondering if i could use my phone as a bluetooth stick for my pc, so i can connect with my bluetooth headset.

If this is not possible, i have another question.

Can i use my phone as a speaker for my PC? Via the USB cable or something?.

I hope that 1 of you guys can help me.
