[SOLVED] Audio devices aren't connected at boot-up

[AngrySeaBone]

Hi, I have a strange problem with my new mobo (ASUS B450-F GAMING II)

Audio devices:
-Microphone; NEEWER NW-700
-Headphones: YAMAHA HPH-MT5

If I connect audio devices to the front panel I have no problems at all, they work perfetcly.
But when I connect them (both microphone and headphones) to the REAR panel, the system doesn't recognize them (as they weren't connected). So they are not shown in pulseaudio menu and ofc can't use them UNTIL I unplug and re-plug them in. At that point they work flawlessly, even after 48h nonstop, not a single problem. I've tried to suspend the pc and when it turns back on the devices are still connected and perfectly working.

I didn't find many informations on internet, but the strange thing is that generally it's the front panel which causes problems (ex. wrong pins position on the Mobo), so it surprises me a little bit.
I also thought about an electrical problem, maybe the motherboard wasn't giving enough power to my audio devices, but, it's improbable since I would have problems with booting up the entire system or at least with other peripherals too, but again, nothing. The other thing that makes me think that's not a power-related problem, is that, when I plug the devices thay work perfectly, I mean, not a single problem with "crackling" input/output sound, which is common in those cases, infact, when I use these headsets on a laptop it's pretty common to experience these types of audio problems.

Could it be some driver or kernel related issues? I don't have any other ideas, since when plugged it manually I don't have problems, I do really doubt it's a motherboard problem.

Hi there. You've said the correct configuration survives a suspend...does it survive a full power cycle? If so, you probably just need to leave them plugged in. My guess is that it's either a power management thing, or maybe something to do with the way your motherboard decides how to configure the jacks for stereo, 4-channel, 5.1 or 7.1 surround output...just wild guesses, but the point is, it's not really broken if it works permanently once it's plugged in. One thing you could try, if for some reason you want to be alternating your headphones between the front and rear jacks, is keeping something like desktop speakers with a headphone pass-through plugged into the rear of the PC. That's easier anyway (well, usually...I guess it depends how you've positioned your PC), and if you keep the speakers plugged in, maybe headphones plugged into *their* jack would work straight away...?
