By default the sound files for that example need to be mono. Yours is stereo. Try using the -c option to set the number of channels to two.

USAGE: confsample [options] [file1.wav] [file2.wav] ... options: -d, --dev=NUM Sound device use device id NUM (default=-1) -r, --rate=HZ Set clock rate in samples per sec (default=44100) -c, --channel=NUM Set # of channels (default=1 for mono). -f, --frame=NUM Set # of samples per frame (default equival 20ms) -b, --bit=NUM Set # of bits per sample (default=16) fileN.wav are optional WAV files to be connected to the conference bridge. The WAV files MUST have single channel (mono) and 16 bit PCM samples. It can have arbitrary sampling rate. DESCRIPTION: Here we create a conference bridge, with at least one port (port zero is always created for the sound device). If WAV files are specified, the WAV file player ports will be connected to slot starting from number one in the bridge. The WAV files can have arbitrary sampling rate; the bridge will convert it to its clock rate. However, the files MUST have a single audio channel only (i.e. mono).
