[gst-devel] ALSA locking up

I have an annoying problem with running some audio pipelines. ALSA driver seems to lock up and after that my alsasink element always bails out with "Could no open audio device for playback. Device is being used by another application." Usually I can run my application once with working audio output but after that ALSA seems to still think someone is using the device while the pipeline has already been killed. I'm using Ubuntu linux as my dev platform and so far I haven't been able to find a way to make alsasink work again - other than rebooting the whole computer.

Playbin elements still work, but I don't think I can use them as I want to play audio stream produced by my own custom element (outputting PCM) and not just from URI. Any ideas how I could prevent ALSA locking up or how to use playbin in a way it would get buffers in like normal sink element?
