Detailed Description

Pass input directly to output.

Note that some HW devices, for example many ISA audio cards on PCs, do NOT support full duplex! For a PC, you normally need a PCI based audio card such as the SBLive.

While adapting to V19-API, I excluded configs with framesPerCallback=0 because of an assert in file pa_common/pa_process.c. Pieter, Oct 9, 2003.
