Same issue playing a wav file. Pulseaudio verbose log

If it can be useful, I have the exact same problem simply playing a song in wav
format with paplay. The command is: 

sudo -u pi paplay --volume=50000 /home/pi/Desperado.wav

If I play the song with pulseaudio running as a daemon, the CPU used by
pulseaudio squirts to 87%, and there is no sound, but if I run it with: 

LANG=C pulseaudio -vvvv --log-time=1 > ~/pulseverbose.log 2>&1

the song feels latencies, sobs and accelerated. 
I enclose the pulseaudio verbose log, hoping it will be useful.
