Thank you for replying! Enabling loopback in alsamixer: http://i.imgur.com/lNo6e7T.png And unmuting more and more things in "Mic Playback Volume" in hdaanalyzer: http://i.imgur.com/H0HiOhy.png made white noise come from the headset. However it did not change or react at all when I talked or even muted the microphone physically. I couldn't find "Mic Playback Switch" anywhere in either alsamixer or hdaanalyzer. The microphone works perfectly fine under Windows, so I don't think it is the mic pin. -Håvard Den man. 10. sep. 2018 kl. 22:39 skrev Takashi Iwai <tiwai@xxxxxxx>: > On Thu, 06 Sep 2018 20:44:30 +0200, > Håvard wrote: > > > > Additional relevant info: > > > > A similar issue was also discussed three years ago on Sun Jun 17:15:54 > CEST > > 2015 and was about his surround sound setup, but did not touch on the > > external microphone problem: > > > http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/093317.html > > > > alsa-info.sh: > > > http://www.alsa-project.org/db/?f=1d8616ba5977308e03db6c3a86e36e9e9b38d6f0 > > > > Graph of ALC668 chipset from hdaanalyzer: > > http://i.imgur.com/c08DNJW.png > > > > setting alsa-mode[1-8] does nothing to help the issue. > > > > There are several of similar bug reports around the web experiencing > > similar issues, and on different distros. > > > > Microphone works perfectly in windows > > > > I have a ASUS ROG G751JT, but this problem seems to happen with all > laptops > > under the G751 name. > > When you enable the loopback volume and switch, and unmute/adjust "Mic > Playback Volume", and "Mic Playback Switch", do you hear the input > from the ext mic?
