Title changed to:
    SDL doesn't play nice with esd (tries to open /dev/dsp directly)
Summary changed to:
    Since the ubuntu desktop uses ESD (or another audio multiplexing daemon) by
    default, it would be nice if apps shipped expecting (or at least adapting
    to) that configuration.

    For SDL applications, the easy fix is to change the default backend to
    libsdl1.2debian-alsa, rather than libsdl1.2debian-oss
Description changed to:
    The default SDL backend for Breezy is OSS, resulting in the following issue
    reported against pygame:

    Since the ubuntu desktop uses ESD (or another audio multiplexing daemon) by
    default, it would be nice if apps shipped expecting (or at least adapting
    to) that configuration.

    Amusingly enough, disabling the sound with "-q" results in the same
    exception, although the man page suggests:

           -q     Begin with sound disabled.

    "strace -eopen pathological" reveals:

    open("/dev/dsp", O_RDWR|O_NONBLOCK)     = -1 EBUSY (Device or resource busy)
