miro's xine backend does not produce any sound output on Ubuntu jaunty

I have recently upgraded my Ubuntu installation from 8.10 to 9.04. Since then, miro, unlike other xine applications does not output any sound until I suspend the pulseaudio sound server. Other xine applications, like totem-xine play just file with pulseaudio. To make matters worse, there seems to be no way to configure xine settings in miro. Other apps use a xine_config file, e.g. ~/.config/totem/xine_config, I cannot see anything like that. I also tried editing ~/.xine/config, and I added audio_driver:pulse. However this did not help, and additionally it should not even be necessary, because xine should be able to auto-select the correct driver. Also, pulseaudio provides a virtual alsa device, which alsa applications can use, but this also did not seem to work. I have set up a pcm.pulse in my ~/.asoundrc, which I can use with aplay, but unfortunately I cannot find a way to tell miro which alsa device it should use.

I could of course switch to the gstreamer backend, but then, miro does not create thumbnail icons for newly downloaded videos. Is this a known issue?
