My audio jacks (all of them) have an issue only with accepting audio in, but not with outputting audio. They do that fine, but when attempting to use an audio jack as a line input, there's a very, very small bit of sound that comes through distorted only when every single volume slider is maxed out. The distortion is such that when there's a short sound, i.e. a notification ding, it comes through almost unhindered, but when a YouTube video is played (my main purpose for my line in) only the background music is intelligible. I currently use a Bluetooth receiver that outputs via an aux cable in conjunction with my Galaxy S7, so if there's a way to bypass aux entirely, I would prefer that, though as far as I know, Windows 10 doesn't support that.
I have a Gigabyte GA-A320MA-M.2 motherboard and I'm using the integrated audio with that, which was working until about a week ago. I have tried multiple devices, cables, and every single port, as well as updating the drivers. All of them. I have fresh installed Windows again, as well as specifically downloading the Realtek audio drivers from the Gigabyte website.
If there is anything else I can do to fix this, I would be glad to hear it. Thank you!
The next thing I will try is a bios update, because it's been awhile since I updated it anyway. (Update: it did nothing, and I'm not sure why I thought it would work)
