"SDL failed to open audio: No available audio device"

I'm hoping this is the right place to post this. Machine id a ThinkPad X200 running Kubuntu 9.04. Sound works on other applications and is OSS.

I get no sound at all with Kdenlive, though video plays just fine. I've tried "Auto" and "OSS" in the playback driver setting, but in each case i get the error ""SDL failed to open audio: No available audio device". This error appears no matter what driver I select.

No doubt somewhere here there is a discussion/remedy of this, but I've not been able to find it; my apologies if this is something that is found in TFM someplace!

Anyhow, I'd love to get it working, and if there's a magic incantation that will allow me to do so, I'd much appreciate hearing about it.

Thanks in advance.
