alsa lib <= 1.0.7 and gstreamer/gst-plugins

I can't play sound with gstreamer using alsa (alsasink). The command always stops with: pcm.c:2097: snd_pcm_wait: Assertion `err == 1' fail.

After applying the patch below it works :-)

        err = snd_pcm_poll_descriptors(pcm, &pfd, 1);
-       assert(err == 1);
+       if(err < 0) return err;
       __retry:
        err_poll = poll(&pfd, 1, timeout);
        if (err_poll < 0)

This patch is for alsa-lib-1.0.7 but also works for lower versions, you may have to change the line numbers.

I've found the patch at:
