Errors when using package

Error: The driver can't connect to the sound card

Exception in sound startup. Is the speaker connected? Have you configured ALSA? Can aplay play sound? Have a look at http://pr.willowgarage.com/wiki/sound_play/Troubleshooting Will retry in 5 seconds. Error message: No available audio device


sudo /etc/init.d/alsa-util restart

The speaker should now default to the enabled state.

There is a red light on the speaker

See Error: The driver can't connect to the sound card.

Error: There are no error messages and no sound


Error: Sound coming out of wrong device

Sound plays from the wrong audio device.


Error: There is no sound if the speaker is disconnected and reconnected

If the speaker is disconnected and then reconnected, soundplay_node.py will not play any sound, and will not report any error messages.

Solution: Due to limitations of pygame, soundplay_node.py cannot detect that the speaker was disconnected unless it is left idle for about ten to twenty seconds. If you disconnect and reconnect the speaker, you will have to either restart soundplay_node.py, or have it not play any sound for at least ten to twenty seconds.

Error: Speech synthesis does not work, but playing sounds works

Festival is not installed

Festival has no voices installed
