Ubuntu - Acer Swift 3 - Acer Swift SF314-54 - Alsa - nf - ALC256 - Microphone - Input - hdajackretask The keywords for your Google searches are: Analog? That is what i found on your Fri 3:15 pm post. Then i would suggest you try every possible nf option for your chip/codec: ALC256 Analog. You could try installing Ubuntu, Lubuntu, Xubuntu, LM Xfce or Mate, you would still be stuck with this problem.Ī good title would be: " Acer Swift 3 - Internal Microphone not working " Because it is a hardware-specific issue.įirst, try changing the Mic Boost setting, as i said before. I don't have that option in alsamixer there is only such an option with dmic But when the Mic Boost is set to zero, well. At intermediate values it is still mainly white noise and the bar graph moves a bit, randomly. When Mic Boost is at 100, the input level is so over amplified it is just 100% white noise and at maximum volume and the bar graph is not moving at all. The default value was 100 before i permanently changed it to zero. On my little notebook, there is a Mic Boost control. How does it looks now on the input tab? Try some mic input software like Cheese. Do you see any Mic Boost level? Is it turned on? Set it to zero. Do you still get "movement for inputs in the sound preferences however the movement is not consistent with any sounds" !? I hope so. It takes just a few seconds.įirst, make sure you are still using that line: I really insist you give a try to my instructions in my preceding post.
