So I've tried uninstalling the software and drivers completely, re-installing them directly from Asus' website and searched for an update (just in case) in both Windows 10's Settings and Asus' ARMORY CRATE and the audio and microphones still doesn't work and I still get the same error message. I then ran the troubleshooter again and got the same error message. I looked for an update in both the Windows 10-update section in Windows 10 settings but also looked for an update in the Asus ARMORY CRATE software, and obviously there was none available since I had just downloaded the latest drivers from Asus' website. Then I downloaded the drivers again from Asus' website under the download section for the Asus G14. I quickly figured out that this had something to do with Realtek(R), probably the drivers, since I ran the troubleshooter and got an error message (see screenshot below, it's in Swedish but it basically translates to): "Audio devices not responding". First I tried updating the drivers (there was no update available) and then uninstalled both the Realtek(R) software/app and all the drivers from the Device Manager under the Sound, video and game controllers-section. However, when using an external USB sound card, everything works perfectly. Both the built-in speakers, built-in headphone jack, and built-in microphones stopped working. Today, out of nowhere, my audio suddenly stopped working on my Asus G14 laptop (GA401IV-HA112R).
