.....38-11 kernel upgrade with, among other issues addresses also
* ALSA: hda - Use LPIB for ATI/AMD chipsets as default
- LP: #741825
* ALSA: hda - Enable snoop bit for AMD controllers
- LP: #741825
* ALSA: hda - Enable sync_write workaround for AMD generically
- LP: #741825
installed. it did no good as far as int/ext mic sensing is concerned. only the left speaker tested good, there was no response when right speaker tested. the only change from prev .....38-10 is that alsamixer shows under F4 capture a mic bar but the mic (internal) had no sensing. an external mic was then connected - same results.
yes, thank you.

so back to ppa (#20)
sudo add-apt-repository ppa:ubuntu- audio-dev/ ppa && sudo apt-get update && sudo apt-get install linux-alsa- driver- modules- $(uname -r)
after reboot the external mic was immediately seen/sensed and skype test center replayed the input.
