Microphone on Acer sf314-54g (swift 3)

[falc0n]

Hello. I have problem with my mic on laptop. It works on windows, but does not work on Linux mint 19 Cinnamon. The alsamixer, qasmixer and pulse audio vol. control doesn't help. So, I think, there is problems with drivers. Even if I plug headphones with mic, it doesn't work. It works only if I plug my web camera by usb.

Here is inxi -Fxzd code:

Hi falc0n, and welcome to the forum.

In alsamixer, I noticed no mic setting. In your screenshot, Master is selected (shows in red.) Try hitting the right arrow at least ten times to see if there are more options hidden off the page. If you see Mic, and it shows MM below, pressing m will unmute it when it's the selected column.

Hope that helps.

Forgot to add, also unmute those other columns with MM at the bottom. Especially Master!

I have same problem on SF-315-52. I trying to fix mic issue adding 'options snd-hda-intel model=laptop-dmic' in '/etc/modprobe/alsa-base.conf' file. Still not working. Something trouble in alsa-driver for ALC256 chip.

[MrEen]

From searching the interwebs, it looks like you both need to follow the steps here: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

For Linux Mint 19, you'll want to follow the links to the Bionic version of the .deb file.

Good luck.

I already make this 2 times. Still same.

What is the output of dmesg | grep snd and aplay -l and inxi -Fxz

Also, have you tried changing options snd-hda-intel model=laptop-dmic to options snd-hda-intel model=laptop-amic and testing after a reboot?

I tryied set model with laptop-dmic and laptop-amic options. But from Internal Microfone only noises if set volume more than 50%

This line from dmesg shows that you made some modifications using hdajackretask:

Code: Select all

[    5.920620] snd_hda_intel 0000:00:1f.3: Applying patch firmware 'hda-jack-retask.fw'

As whatever changes you made are not working for you, I'd suggest you run it again and click on Remove boot override.

Now from your last post I assume you're trying to make the internal microphone function, so maybe you should reboot first, then again run dmesg | grep snd and see if this line is still the same:

Code: Select all

[    5.942495] snd_hda_codec_realtek hdaudioC0D0:      Internal Mic=0x12

This way we know the original pin connection and not something created by your change.

First, I assume you have checked alsamixer to make sure the Internal mic is not muted. Is this so? Does Internal mic even appear? This area might be better to investigate before trying what's next.

Now run hdajackretask again, check the Override box for the Internal mic and change it to Not connected. Then click on Show unconnected pins and change one of these new items by again checking it's Override box then selecting Internal mic then click on Apply now and test your mic. ONLY if this works should you then click on Install boot override.

Good luck.
