MOC throws strange error

I'm running Debian Linux. When I try to start MOC, it throws these errors:
Running the server...
Trying JACK...
Trying ALSA...
mocp: alsa.c:319: alsa_read_mixer_raw: Assertion 'RANGE(0, vol, 100)' failed.

FATAL_ERROR: Server exited!

I'm not sure where it's pointing me to, or whether it's a problem with my system or with MOC

Forums:

It is a known problem. PulseAudio allows to set volume higher than 100% and MOC doesn't like that.

Proper PulseAudio backend is in the works from what I know.

For reference, the issue was discussed in http://moc.daper.net/node/1600 and http://moc.daper.net/node/1760

I didn't know about this problem, but...I lowered the volume in my settings and MOC starts working again!

Thank you everyone!
