7.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <[email protected]> [ Upstream commit a8934c2c6dfd72901cf3cc0de28e85eb902a61a4 ] The recent fix for sticky mixer volumes caused regressions of M-audio Fast Track Ultra device, where the mixer state is kept to the default value. Add the quirk entries to tolerate the broken mixer behavior. As the device is known to work in the implicit feedback mode, explicitly enable the implicit feedback mode, too. Since there are two FTU models that are almost identical, both entries are added in this patch (0763:2080 and 0763:2081).
