-/** @file patest_wire.c
- @ingroup test_src
- @brief 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.
-
- @author Phil Burk http://www.softsynth.com
-
- 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.
