Jokosher - "Error loading file: None"

[Stephen]

Error loading file: None

Please make sure the file exists, and the appropriate plugin is installed.

Could not determine type of stream.
gsttypefindelement.c(742): gst_type_find_element_activate (): /pipeline0/decodebin0/typefind:
Can't typefind empty stream

All,

Just installed 0.10 on Ubuntu Hardy (fully patched system, all Gstreamer plugins installed if that helps). I started a new project and added an "Acoustic Guitar" instrument. The track was armed by default, so I clicked on "Record" and strummed a few chords. After that I clicked on "Stop" and the above error messages appeared.

My "setup" is - Dell Inspiron 9300 with a Lexicon Omega USB recording device. I don't think JK "sees" the Lexicon so maybe that is the issue (shrug). Please let me know what (if any) other information I can or should provide.

Also, please let me know how I can help!!! When I first saw this program I thought it would be perfect to use (Ardour is a bit much for me and sound recorder doesn't cut it). I don't know how to code (very well) but I'm willing to test/report bugs/etc. etc.

What is happening is that when press record, it tries to save audio to a file, and when you click stop it tries to load that file as an audio clip and display it. However when you click stop, it finds that the file doesn't exist. This means the previous recording step failed to save any audio.

When recording (before you hit stop) do you see any green waveform being displayed on the instrument?
Can you try running Jokosher in a console and paste any error messages you get when you try to record?

Thanks, this should help identify the real problem.

Hi Stephen,

 Jokosher 0.10.1 should have no trouble detecting the Lexicon Omega USB (I've just purchased one myself). If you go to "Project -> Recording Inputs" and select the "USB Audio #1 input 0" device listed there you'll be able to record from inputs 1 and 2 on the device (as a single stereo track).

 By default Jokosher will be recording from your internal sound card (or whatever your system has setup as the ALSA default), so if you could try doing the above and see if you still get the same issue we can see whether it's related to your internal sound card or if it's a different problem.

 Also, make sure you're using the official 0.10.1 package for now, don't use a bzr checkout of the very latest code, as this device triggers bug #305988 (I'm currently working on resolving this, so it shouldn't be an issue in 0.11).

Cheers,
 Mike.

I have the same problem on Ubuntu lucid with Jokosher 0.11.5

Here are the steps in use to repro:
Start Jokosher normally (or in safe-mode)
Open project
Add an accoustic guitar instrument (or vocal)
Press record (no green waveforms displayed)
Press record again (or stop)
--> Error message is displayed "Error loading file: None".
