[Bug 1395501] Re: input devices found, but there is no input level

 

upgraded kernel to 3.16.0-30-generic.

Internal soundcard is now recognized as Realtek ALC3661, wich is
correct.

$ grep -r Realtek /proc/asound/card*
/proc/asound/card1/codec#0:Codec: Realtek ALC3661

Still have problem with mic not working, happens to my internal mic, external mic and external usb-sound card.
The weird thing is that mic works fine if I boot PC from a Ubuntu 14.04.1 USB boot key.
