Hi Srinivas,
As I mentioned previously, you will have to modify the code in MSP430 in what the buttons do and the commands sent to the PCM3070 relative to that. If you try to program the PCM3070 directly with SRS WOW, are there any issues?
The code given for the RDK Value SB has those outputs as a sub-woofer out. This can be modified for HP output.
When you say the MSP430 is not detecting interrupt, do you mean that the device sees the interrupt on the line and isn't responding? or that the interrupt from the IR receiver is not occuring? Have you tried using another remote with the original code?
Regards,
