2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------ From: Takashi Iwai <[email protected]> commit 62b7e5e09bcb854ff05e6ee1aa161f8283dc36ee upstream. Creative IBG controllers require the playback stream-tags to be started from 1, instead of capture+1. Otherwise the stream stalls.
