OK, then upgrade your alsa driver stack to 1.0.21.  There have been some changes in PCM core.  Then, get dummy.c again from the latest alsa-driver-unstable tarball.  It already contains my latest fix.

If 1.0.21+dummy.c doesn't work, apply the patch below to get position logs.  If this still causes the invalid backward jump to position 0, you should check xrun debug, e.g.        # echo 9 > /proc/asound/card0/pcm0p/xrun_debug

I'll do it and report
