Hi all,

This has got nothing to do with Windows 10, but perhaps you may make
me think into the right direction.
This is the case:

Recently purchased a front panel audio connection bay 3,5". The make
is Delock. There are two USB 3.0 connectors and a HD Audio in- and
headphone output. There are no electronic devices in this thing, it
has connectors and cables only. USB cables are connected to USB 3.0
connectors (20-1 pin) on the motherboard, works fine. The audio cable
ia connected to the front panel audio connector (AAFP, 10-1 pins) on
the motherboard.

Motherboard is Asus Prime H270 Pro. System is W10 Pro 64b.
Audio chip is RealTEK ALC 887, default audio output is Realtek High
Definition Audio (on the motherboard). In the BIOS the audio chip is
enabled.
Driver is correctly installed, when playing a music file there is an
audio signal at the rear audio output on the motherboard. But there is
no signal at the audio output of the front panel.
In the Realtek Audio Manager these are ticked: Make front and rear
output devices playback different audio streams simultaneously. And:
HD Audio front panel. This is what the front panel is, no AC97.

So I think there should be a signal on the front panel output, but
there isn't. As the frontpanel contains no electronic devices, chances
are zero this panel is at fault.
But what can it be? Do you have any suggestions?

Thanks in advance,

Fokke Nauta

USB both working ok.

Yes.

Both audio channels completely dead?

The headphone output is. Can't check the microphone input as I have no
microphone (or another sound device) with a 3.5 mm output jack.

The headphone is 35 ohms. Perhaps I can use it as a microphone, to see
what the mic input does.


Or recognised by Realtek?

How can I check that?

Neither microphone nor headset work?

As I said, can't check the input.
The head set output is dead, I don't hear even a click when I put its
plug in. The head phone itself is OK.

Are you trying it with major speakers when it can only handle
low-powered things?

It has the head phone symbol next to the output. So I assume a regular
head phone should work. But I can measure its impedance.
