I've encountered this problem frequently while trying to run pykaraoke; only tonight did I trace it to pygame.mixer.music.play(). The strange thing is, it only happens on multiprocessor systems; if I do the test on a single-processor system, or boot Linux with "maxcpus=1", it doesn't happen. Otherwise, the hard hang happens regularly, and I have to use SIGKILL, because SIGTERM doesn't work.
This is a software that can be installed with a simple sudo apt-get install pykaraoke. But, this somehow did not do what it is supposed to do. ?
So I figured out a new way to do this (after a LOT of googling).
Now we will see the commands for uninstalling the python-pykaraoke from Ubuntu 12.04 LTS. For uninstalling this package you can easily use the apt command and remove the package from Linux Operating System.
