What's receiver? Can I have it directly to tv via hdmi?
Toslink gives separate audio out over optical fibre for people who connect AppleTV via HDMI to the TV rather than to an AV amp/receiver - they can run HDMI to the TV and have sound/audio there, but can also run optical to the hi-fi/surround system to get better stereo or surround sound.
If you have an amp/reciever capable of HDMI input you probably don't need optical, but older ones won't have it.
