[SOLVED] Problem of interrupted/crackling sound in mocp

Hello,

I installed MOC player from the official repositories (# pacman -S mocp ) , when I play any music file in it I'm getting the sound full of interruptions, as if I'm playing/pausing the sound every half a second.
I have all the required and optional dependencies installed, I have no user specific configuration file (no ~/.moc folder ).

Juste to be precise : I'm using Pulseaudio 5.0 in my Arch installation, and I noticed that mocp uses alsa. (there is only alsa installed from the following list : sndio, oss, alsa, jack, null; and all the others give FATAL_ERROR: No valid sound driver!).

I can't get the reason of the problem.
Any help please ??

EDIT: Solved by launching mocp with the padsp (PulseAudio OSS Wrapper)

$ padsp mocp

Re: [SOLVED] Problem of interrupted/crackling sound in mocp

 Is pulseaudio-alsa installed and alsa redirected to pulse in /etc/asound.conf? Does ~/.asoundrc exist? MOC has an OutputBuffer parameter, increase it. PA should have the correct buffer/period / fragment size set, refer to its wiki. Also take a look here.

Have you tried 'padsp mocp'?
