Windows Speaker Enhancements

Which options would you use for a laptop with a pair of M-Audio Studiophile AV 40 speakers?

Speakers are connected via the 3.5 headphone socket to the phono L+R line in socket.

I have TRS inputs on these speakers, will there be any benefit in connecting via that route instead?

The bit depth format is set at the maximum 24 bit 192000 hz (Studio Quality) setting for best output.
