I am using rpi for airplay with same speaker that I use for my pc. So I don't want to deal with cables everytime when I pass to rpi from pc. Can I connect audio output of pc to input of rpi and get all the output (both pc and airplay) from rpi without any latency? I am using usb soundcard for the input and output.

I have looked how to redirect sound with using alsa but I couldn't figure it out.

  • It's not possible to do anything without latency. That's simple physics. How much latency is tolerable? – Jacobm001 May 27 '15 at 17:26
  • as long as human hear doesn't recognize latency at videos and games it is okay. So i think it shoul be below 100 miliseconds – user3160302 May 28 '15 at 6:49

Simpler fix:

Buy a 3.5mm audio jack splitter
