[alsasink] no sound with Ubuntu 7.10 (cannot open device 'default': no such device)
Last modified: 2007-11-03 14:55:14 UTC
the error message with sound juicer Internal GStreamer error: state change failed. this error from Ekiga sftphone: An error occured while trying to record from the soundcard for the audio transmission. Please check that your soundcard is not busy and that your driver supports full-duplex. The audio transmission has been disabled.
Go to System => Preferences => Sound and configure the 'Music and Movie' sound output. Maybe you've got esd configured or so - try other options. (And I don't think Ekiga uses GStreamer ..)
Created attachment 98421 [details] Error message when try test I tried the utility. The error says files aren't there Or my card isn't working?
The error message isn't very good (fixed in CVS). Could you try this in a terminal/command line: $ gst-launch-0.10 audiotestsrc num-buffers=10 ! audioconvert ! audioresample ! alsasink and tell us the full output? Could you also do this: $ sudo lsof -n | grep /dev/snd ?

Ok, this is a bug with your distro or alsa then - there really should be a 'default' ALSA device. Please file a bug with ubuntu (and do mention this bug to make sure they're not forwarding it back to us again). You might be able to work around by running this from a command line: $ gconftool-2 --type string --set /system/gstreamer/0.10/default/musicaudiosink 'alsasink device=front' If this doesn't work you can reset it again with: $ gconftool-2 --type string --set /system/gstreamer/0.10/default/musicaudiosink 'autoaudiosink' or by using gnome-sound-properties.
