GA-Z170X-Gaming 7 no sound

[zulu9812]

I've had this motherboard for three weeks. I had my computer switched off overnight and when I switched it on this morning I got no sound.

Windows 10 x64 is not detecting any device issues, as far as it's troubleshooter is concerned the device is functioning properly.

Sound Blaster Recon3Di is set as my default playback device and there's a little bar to the right in playback devices that moves up and down when I play some music (but can't hear anything, obviously).

I've tried connecting my head phones to the head phone socket and the line out socket (o and k respectively, referencing the Back Panel Connectors diagram in 1-7 of the manual).

I've tried two different head phones.

I'm running BIOS version F5, which is the one that was installed on the motherboard when I got it. I tried to update via the @BIOS tool in the App Center but on restart my system wouldn't boot so I had to go into BIOS and restore system defaults.

Speaking of BIOS, under Chipset > Audio Controller, Audio DSP is set to disabled (and has always been set that way).

I've tried re-installing audio drivers, downloaded from the Gigabyte website, and selected to Repair the installation. This proceeded without any error messages, I restarted the system when prompted and... still no sound.

This is most frustrating, so if anyone can assist, I'd be really grateful.

Greetings,
I'm not in front of my laptop running W10, but if everything looks like its installed and working (correctly), but no sound, please ensure your output is set to analog and not digital if you are using a standard analog headphones. Its often something as simple as that when this happens.

Hi, thanks for your reply. I am indeed using analogue head phones. How can I check if the output is set to digital?

In the end, I went into Device Manager and, under Audio Inputs and Outputs, uninstalled the back panel ports. They were automatically re-installed when I rebooted and now sound works. So that's something to bear in mind if this ever happens to me again (or anyone else). Matter closed, I suppose.

Greetings,
Glad you got this sorted.  A few things as far as insight on this issue goes.  Uninstalling and reinstalling drivers can sometimes resolve the problem as this will often reinstall the (most common) default Recording and Playback devices.  It gets a little more difficult when a manufacturer includes their own application for audio control.  Sometimes the enhanced features they offer adds another layer of complexity and more places to create issues for one's self   Port sense is another problem area where you can get undesired results if you connect a device to a port and the application expects something different.  The Sounds option in Control Panel is often a good place to start.  If you have a custom Audio Control installed this is usually found in the System Tray.

an update

The sound has stopped working again (this time after wakening the system from sleep). I tried my previous fix outline above and it didn't work. So I've no idea why it's not working or how to fix it.
