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.
