The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume.

Hello guys. After googling for 3 days and being unable to resolve the audio issue for some time I was looking for the schematic and I found this wonderful website.
It all started from sound just disappearing at some point that I even forgot when. Why did I forget? Because even though speakers and 3.5mm give no reaction whatsoever it works properly with type-c earplugs so I kinda kept using it like that.

I have 3 DELL Latitude 7430 with faulty MBs and 2 DELL Latitude 7400 with broken screens.
Both have 14'' touchscreen with 30 pin eDP
I try to connect the 7430 screen to 7400 and getting picture OK. Yuppie!
So far so good...
Reboot in BIOS settings to check battery, processor type , etc. everything is OK even the touch is working.
At this point I know everything is fine with pin assignment.
I installed a Windows 10 Pro x64 and as a big surprise the touchscreen is not working!
There is no mention about touchscreen in Device Manager… no device with yellow...
