Thank you for suggestion.
I've installed 7.1-BETA and mixer is working, after using the same steps
with loading snd_hda, although "<HDA Codec: Realtek (Unknown)>" is still
unchanged. Probably it's not codec after all, but KDE/PCBSD specific
weirdness, since OS version difference is less than a month. There's also
only one /dev/mixer0 for a change.
