error: 'SS_SERIAL_A' undeclared

I'm trying to compile a xalib under PSN00BSDK, and I get this following error during compilation:

I need some serious help

PSn00bSDK's psxspu does not support the SS sound subsystem as libspu given away by SsSetSerialVol being undeclared at compile time. In fact what is currently implemented in psxspu is pretty half-baked and frankly quite limited.

Ok, but are you planning to implement them anytime in the near future?

The official SDK's libgs and libsnd are high-level libraries that make heavy use of proprietary file formats and are well out of the scope of PSn00bSDK. Implementing their API would be a waste of effort for the most part, as they are inefficient, bloated and poorly documented. A custom MIDI sequencer library might be added in the future instead, but there are currently no plans to do so.
