Hi I m searching since 2 weeks for a way to controll my dac preamp with the googletv remote. My dac (matrix mini dac) is not a soppurted amplifier but I was hopping to still make it work. Can someone tell me if another manufacturer uses this reciever chip or codes? Ir chip pt 2212 Codes K1 0x303000ff VOL_UP K5 0x303020df VOL_DOWN K9 0x303010ef POWER K13 0x303030cf SOURCE K17 0x303008f7 MUTE I only need vol up and down.
