Hi there, I'm pretty well versed in computers, haven't had to pull log files out before though. I normally fix my own problems by viewing other peoples problems or writing a small piece of script.
I'm running an MSI Gaming Laptop. It came pre-installed with windows 10, but a few years ago I uninstalled and installed windows 7 Ult and put all the drivers back on. Then paid for lifetime service for a program (driver tuner) which does a great job of updating and reinstalling them (way way way better than windows software).
Anyways Last night I was hooking up my entertainment stand, I have recently moved out and had 14 consoles and 2 computers or so to rig up between 4 monitors. I have a few HDMI spliiters, and an HDMI switch. While trying to split the HDMI out from my laptop to my desktop screen and the big screen across the room my laptop suddenly restarted. (This occurred during insertion of the HDMI cord to the laptop port). The splitter is self powered by 5V direct current, and was hooked up to both monitors and my laptop correctly.
I unhooked it, and restarted my computer.
Tried a different 5V direct current adapter to power the unit and hooked it all back up again.
My laptop restarted again immediately upon insertion.
However this time during re-boot I noticed (or rather my girlfriend noticed) there wasn't any sound during boot (I have a custom sound scheme), and my main desktop display was no longer displaying. To add to this my laptop resolution had reset to the lowest display setting possible as well.
After a little fiddling with the cord around the port and a few re-boots, various trips to "connect to an external display" my laptop was able to re-recognize my desktop display. However I still have/had no sound.
Bluetooth speakers do work, and my logitech Bluetooth speakers that have their own adapter work as well.
Sound does play through the HDMI cable out my TV if it's set as default.
I have tried:
Uninstalled and reinstalled the realtek HD sound drivers.'
Uninstalled, and let windows re-install it by itself.
verified it wasn't muted, and that it is set as default.
verified there isn't any sound or distortion coming from either the speakers or the 3.5mm jack out.
Running windows trouble shoot.
I've updated to the latest version of windows.
Windows displays audio playing on the device when I open Playback devices.
The device shows up in device manager.
the driver shows up as installed correctly in device manager
I have not:
Flashed the BIOS
Tried to make the motherboard re-find the card (I don't know how to do this in BIOS) / no hardware experience.
Opened the shell to check for damages.
Attached is two screen shots. One of my computer properties, and another of the device manager
