Hi All,
I tested the sample wave record program waverec.c on QNX 6.4,but no sound can be heard when the generated wave file is played back on QNX or Windows player.The sound signal is output from a speaker port of a computer and fed in the Line in port of the test board.
Below is the the output for audio when executing command “pci”

Kindly please help on it.
