Seems that there was some misunderstanding: I thought your patch
for sigmatel.c was supposed to fix the "missing sound" problem,

It does.

rc7 plus the big "clean-up" patch for sigmatel.c plus hda_intel.c
taken from rc6 worked, too. Seems that I missed to mention it in a
previous EMail.

I am glad to help, but could you please do me a favour? If I am
supposed to try some new version, then please create a complete(!)
patch using rc7 on as the base, and send it as an
attachment using a unique filename. Very likely you have a much
better overview about the most recent kernel changes, but some
statements like "new patch" or "Ingo's patch" don't mean very much
to me. The "reverted" patch is a new patch, too, and AFAIK Ingo
reverted it, so maybe you can imagine that this is highly confusing.

AFAICS there shouldn't be a difference to my one-liner, unless Linus'
and Alsa's git trees are out of sync. Is this correct? Sorry, I am
more familiar with ClearCase and Accurev than with Git.
