Please attach the output of `alsa-info.sh` from each state (working, non-working, broken and so on).

Thank you for taking the time posting this question in such a detail. I am pretty sure your problems can be fixed. Please subscribe to the list alsa-devel [4] and post your problem there uploading *and* attaching the output of `alsa-info.sh` [3] when the system is in the different states. Most developers are just reading `alsa-devel`. Please add the maintainer’s email address (Takashi Iwai [5]) to CC, since he is working for openSUSE(?) as far as I know and therefore will hopefully look into your problem very quickly. You could have also submitted a report to the openSUSE bug tracker. Only do that if you do not get any response in due time.
