Sound_ReadSysInfo

| All other registers dependent on reason code |
Use
The purpose of this call is to allow you to read various parameters of the sound system.
Notes
The action performed depends on the reason code value in R0.
Many versions of SoundDMA do not return errors when unknown SWIs are called. Therefore, to detect if this SWI is supported, check if R0 has been set to 0 on exit (Valid reason codes start at 1).
