The problem is that /dev/dsp is the legacy OSS api, and does not |
| 9 |
support dmix (software mixing of audio). Thus only one application |
| 10 |
can access /dev/dsp at a time unless your card supports hardware |
| 11 |
mixing. So most likely, /dev/dsp is already in use by some app. |

The workaround to this is to use a wrapper such as aoss or vmware-dsp |
| 14 |
that fakes out the application when it tries to open /dev/dsp and uses |
| 15 |
another audio API instead (alsa for aoss, esd or artsd for |
| 16 |
vmware-dsp). |

FYI, there is an ebuild available for this...emerge vmare-dsp. |

What does ldd /usr/lib/libvmdsp* report? (or whatever directory |
| 28 |
libvmdsp got installed to..) |

PS:The real fix for this is for VMWare to *stop* using the deprecated |
| 33 |
OSS API for sound, and implement real ALSA compatibility. I highly |
| 34 |
recommend sending this request to them! |
