Some HD-audio codecs (at least ALC269VB and ALC283) become quite noisy on high Mic Boost levels. So e g, if there is a "Mic Boost" and a "Capture" control, both ranging from 0 dB to +30 dB, you get better quality if "Mic Boost" is 0 dB and "Capture" is +30 dB, than the other way around.
By changing the order in the configuration files, this patch makes us prefer leaving "Mic Boost" low and "Capture" high if the user selects a medium gain. (This is based on limited experience, and there is no guarantee that there are no sound cards that work the other way around, and therefore this patch could potentially regress quality on those machines. Hopefully those are fewer, so this is what we should default to.)

This behavior seems right. However, if I record sound with auto selected port, audio quality is very poor. There is loud noise in background. But if I switch to "wrong" port audio quality becomes great. E.g. I have to manually select "analog-input-microphone-internal" port when I attach external mike and vice versa. Example of record: http://self-perfection.homeip.net/files/2012/external_ru.flac (652 KiB) This record is made via headset microphone. During first half of record source port analog-input-microphone was selected then i switched to port analog-input-microphone-internal.
