Just installed Fedora 26 to my laptop, Acer Aspire V 15 Nitro (VN7-572G-57N0), and found out that microphone is not working (both internal or external). The output on both speaker and headphone work perfectly, just the input has some problems here.

I followed the steps stated here: https://fedoraproject.org/wiki/Howtodebugsoundproblems however still can't get it working. Output of 'alsa-info.sh --no-upload' pasted below. Remove PulseAudio won't solve the problem so I assume it wasn't the cause. I managed to get external microphone working, after I tried to add 'options sndhdaintel model=dell-headset-multi" to sound.conf. The internal one still not capturing any input.

I checked this site: http://git.alsa-project.org/?p=alsa-k... and found nothing about ALC255

Same problem in Ubuntu as well: https://bugs.launchpad.net/ubuntu/+so...

Any help is appreciated.
