I have a PC with sound card with SPDIF out and a kenwood 5.1 music system aux in and aux out and also digital/optical out. now iam using connecting cable from PC(one pin) to AUX in of music system(two pins). I would like to know if there is any enhancement in quality of the sound if I connect PC spidif out to AUX in of the music system with a digital analogue converter

Get an external amp and dac

Schiit Magni3 and a Schiit Modi should do 200 bucks. Or for 100 get the Schiit Fulla2. Fulla is an integrated dac/amp

I’m getting the magni3 and modi for work
 
Are you sure that your 5.1 music system doesn't have a digital audio INPUT? Seems odd that it would only have an output.
If it does then just connect the PC directly to it. Check the owners manual on how to set up the input.
When you connect it that way you are using the DAC in the system. An external DAC might be even better than the one built into the music system but you won't get digital 5.1 if you use an external 2.0 DAC.

Make model of the receiver? something dont sound right might need to clarify your question... not sure how you taking a PC 'one pin' to Aux in. are we talking RCA analog or a Digital output from the PC?

if you are running digital output from the PC, then SPDIF will not change anything as its the same data just a different transmission method. optical vs digital over wire. actually you might end up having less latency with a non-optical signal as there is a tiny delay when the data has to be converted. I say this cuz I hear it when I monitor my traktor vs hearing it come out of my home system.

Oh and if you arent using higher then 1080p or if you are using HDMI 2.x then I would use that to connect your PC to your receiver for your 5.1 then the special encoding card isnt needed as hdmi gives discreet channels and would eliminate the need for encoding.

If your connection to your receiver is analog then yes you will see a improvement by going digital transmission.

Key point is you need to clarify what receiver you have and exactly what you mean by 'one pin', because your question has some contridictions in what you doing.

Based on what you said you are already using digital but the whole AUX in of music system(two pins) doesnt make sense at all unless its analog...

If you are using digital you dont need to change anything other then get a soundcard that is designed for 'encoding' discreet PC channels over the 2channel digital connection. Digital out/SPDIF is not discreet multichannel you have to encode it. Anything that supports Dolby Digital Live or DTS-Connect is what you will need if this is ultimately your question/problem.
