I have no idea as to how to set up GCC to rpi but if you wanted to go the usual route of rpi and a plug in audio board its relatively easy.
For example, if you wanted a set up to use with a standalone DAC its simply a matter of buying a rpi, digital output board such as a hifiberry digi+ or an Allo digione, a case and an micro SD.
Assembly is easy fit the rpi to the case and then plug the digital output board to the rpi and close the case.
Then download an OS like picoreplayer and burn it to the SD card.
Pop the SD card in the rpi, use something like ipscanner to find out what the ip addy of the rpi is and then log in using a browser and then follow the easy set up guide provided by piecoreplayer.
It then helps to have logitech media server set up on your laptop so that you can access your rpi set up from there. This is the bit that may need a learning curve if you are unfamiliar with LMS.
All this could easily be completed with 30 mins
