Hi,
whenever I resume the machine, the Input Source would get changed back from "Internal Mic" to "Mic". This is a bit annoying, because pulseaudio is unaware of that change. As a result, everything looks fine in pavucontrol but no sound gets recorded. A quick look at alsamixer -c0 revealed the problem. My alsa info:
http://www.alsa-project.org/db/?f=c5776b615a5f3b9ae624e4250fb0c2b69118ce26
This is unrelated to the other problems I have been reporting, since this happens on a mostly-stock Fedora 3.1.2 kernel (the patch I added deals with xhci, not alsa).
The problem seem can be reproduced by using hda-emu, it is init_capsrc_for_pin() and alc_auto_init_input_src() write value to cache before snd_hda_codec_resume_app() from cache

The problem still exists in 3.2.7-1.fc16.x86_64 kernel, is there any chance for a fix?

A dirty hack is to swap the order of the external mic and internal mic at the end of sort_autocfg_input_pins()
+ if (cfg->num_inputs > 1) { + struct auto_pin_cfg_item tmp; + tmp = cfg->inputs[0]; + cfg->inputs[0] = cfg->inputs[1]; + cfg->inputs[1] = tmp; + }
