I'd like to try soldering SMD components and the only DAC with a Toslink input that I've come across is the y1 from AMB.
 
Are there any other DIY DACs around $100?

Plenty, but not many with a Toslink interface.  Toslink has jitter problems, anyway.  I don't know anyone who uses it anymore.  Either SPDIF if you're hung up on higher resolution (not justified) or USB, either one is better than optical.

I use Dolby Headphone for gaming and movie watching which is why I need toslink.

Then stick with your soundcard.

I think the sound card had an audible hiss which why I got the Fiio.

I would get a USB DAC if there was a way to use Dolby Headphone.
