I have this problem with Ubuntu 18.04, 18.10 and Linux Mint 19, on 2 computers : HP Pavilion dv6700 and Acer Extensa 5620Z, both with a Realtek ALC268 chipset. Audio is working but not internal microphone (and on HP Pavilion, external microphone doesn't work too).

Ubuntu 9.04 Jaunty Jackalope. Sound card is working otherwise ok, but the internal microphone does't work at all. I've tired modifying the alsa-base.conf file's last row to read like: options snd-hda-intel model=acer-aspire, options snd- hda-intel model=acer and the third one for digital built-in acer mic. None of the above have worked. From the user's point of wiev it seems like the microphone cannot be activated at all. If I try to activate my microphone from sound menu (from top right corner on desk top) -> volume control -> record (tab), the microphone is allways showing a red cross (like it is muted). The red cross can be removed, but the red cross appears back after closing the control panel. After test recording with mic activated the result is only static noise during play-back.
