Same microphone behaviour on 2.6.29-rc8 (additionally remembered to enable CONFIG_SND_HDA_HWDEP for further testing!), u9.04, model acer-aspire, libasound2 1.0.18-1ubuntu7, libasound2-plugins 1.0.18-1ubuntu4 (yes, I've just done some monster upgrade). Will try to eventually analyze things using your _HWDEP-related tools. 2.6.29-rc8, in contrast to several other kernel upgrade occasions, seems pretty solid so far, BTW.
