I checked in file(location can differ on Ubuntu against Gentoo): /usr/src/linux-4.8.6-gentoo/Documentation/sound/alsa/HD-Audio-Models.txt
for ALC3266 chip(which alsamixer is reporting) there is an entry: ALC22x/23x/25x/269/27x/28x/29x (and vendor-specific ALC3xxx models) ====== laptop-amic Laptops with analog-mic input laptop-dmic Laptops with digital-mic input alc269-dmic Enable ALC269(VA) digital mic workaround alc271-dmic Enable ALC271X digital mic workaround inv-dmic Inverted internal mic workaround headset-mic Indicates a combined headset (headphone+mic) jack headset-mode More comprehensive headset support for ALC269 & co headset-mode-no-hp-mic Headset mode support without headphone mic lenovo-dock Enables docking station I/O for some Lenovos hp-gpio-led GPIO LED support on HP laptops dell-headset-multi Headset jack, which can also be used as mic-in dell-headset-dock Headset jack (without mic-in), and also dock I/O alc283-dac-wcaps Fixups for Chromebook with ALC283 alc283-sense-combo Combo jack sensing on ALC283 tpt440-dock Pin configs for Lenovo Thinkpad Dock support So these are models we could refer in /etc/modprobe.d/alsa.conf(again can differ on Ubuntu) I mixed it with probe_mask which is known to handle some issues: options snd-hda-intel single_cmd=1 options snd-hda-intel probe_mask=1 options snd-hda-intel model=headset-mic by using first model=generic I got working both speakers and headphones at same time.

I have an external audio speaker connected to it. When I disconnect the speaker and reconnect it again it stops working. Even more, laptop audio stops working too. And after the reboot, I don't even see any of the audio devices. I've googled a lot and tried different fixes from forums with no luck. After a while, I've accidentally discovered that putting the laptop to the sleep mode and rebooting system after brings audio back to live. Even more, if speakers were attached during this sleep-reboot procedure, they are starting to work as well. However, after the next reboot speakers are not working again. And if I will plug them out and in - problem with completely missing audio returns. P.S. I'm using laptop-mode-tools package on my laptop. Recovery after hibernation made me believe that it's somehow related. But after uninstalling this package nothing really changed.
