I have old i don know how many years Define XL R2, last year die blue led on power switch (power on switch). But is weard front I/O for headphone is so bad you canot use this port, my mother board is ASRock Z370 Extreme4, Front Audio is place in good slot on motheboard, i dont know is Case cable is bad or HD audio slot on motherboard is bad. for headphone i use audio port on Back and is best (once i use GPU audio and play weard, diffrent pitch, sound balance or somthing).
I Build before christmas AMD with old Motherboard but with new Bios support Ryzen 3400g and China case, front Audio was prety good, i dont know why on my PC is front audio so bad.
What i want: If is possible replace blue LED around Power Switch.
If is possible fix front audio.
