Only 6 years too late for an answer, but hey, I came here looking for codes for my Sony CMT-RB5 and like you, struggled to find anything. I'll assume you are no longer in need of these codes, but will leave them here for others.

In the end, I bought a development board (NodeMCU) and a handful of IR sender/receiver chips. I can now decode any remote, including my aged Sony remote.

Pwr ON/OFF is 0xA81 (A81)
volume UP is 0x481 (481)
volume down is 0xC81 (C81)

I can supply the other codes for this remote if required, also in RAW format if needed.

Don't just sit there standing around, pick up a shovel and sweep up!
