There is a patch to this issue. As I cannot test this patch right now,
could you please verify that the patch from
http://lists.linuxaudio.org/pipermail/linux-audio-dev/2012-January/032645.html
resolves this issue.

Once verified, I'll checkin the patch, which clearly fixes an error.

Here is a fix from Tvrtko Ursulin (many thanks!!):
