Fishbb,

Please come to hififever office at coming SAT to get your compoennts.

1. Optical receiver.
2. 74HC04.
3. Ouptut coupling transformer (if needed)

You can buy a "hole" board at "Wah-Fai", Sham shui Po, the circuit is simple and you can do it within 5 minutes. Also, the 5V is easy to "stolen" at USB port. There are one USB port at the rear side.

Dear kk_ho,
do you mind telling me roughly how much those you mentioned will cost me? because if it is too expensive, i may just stick to the TV sound.
and will you stay at the hififever office on Sat?
thank you again.
