Hi Alan,
I have a PlexHD X79 Xeon motherboard with an ALC892 codec and 7.1 audio output panel, but no special SPDIF connector, neither optical nor coaxial, and I use only analog stereo speaker output adjust on Realtek audio console.
Also have this:
Connects to Front Audio motherboard header and has a bypass to case front panel for headphone and mic.
All of these worked fine, the speakers sound as front stereo speakers and muting when a headphone is connected to front case panel.
I´ve upgraded to 9301 drivers yesterday, and the front speakers stopped working, despite existing as a sound option, and headphones and mic working ok thru bypass.
The rear center subwoofer remains white as active in realtek audio console, despite nothing connected in that or any other jack.
Both SPDIF remain white as active, despite nothing connected.
Not a single device connected to a jack, this run as above, no sound.
And yes NVIDIA Hda out is not the default audio neither is selected as audio out.
And with a headphone and mic at the front jacks, via case speakers pass thru, the headset works ok.
"Disabled the front panel jack detection" selected off, makes no difference at all.headset sounds ok, as the main device is AAF Speaker Out.
Above , device manager, LH-811'es are bluetooth headset coonections related, One Max'es are my mobile connections via Bluetooth, all bluettoth audio disconnected long time ago and no issues with it at all.
MT-32 is a midi emulator, was installed since forever, and have no issues either
the CODEC
six 7.1 rear audio connectors
Front HD Audio connector is at the left edge of the last picture. Never found a SPDIF connector in the mobo for a coaxial or optical bracket.
In BIOS, however, there is a setting for SPDIF over HDMI, with disable/enable values, resting in disable now, because it mades no sense since neither Xeon processors nor this mobo have on board VGA.
Tried everything within this panel to make my case front speakers 5.25 module work thru HD Audio connector again, zero success.
I believe this is software/drivers related, since things worked ok before driver upgrade. Maybe they´re not correctly tasked for the mobo 7.1 connectors.
Also believe that the new driver makes the codec recognize the front audio panel as center/subwoofer.
Driver rollback didn´t work, many driver uninstall/reinstalls before with no success either, even using ddu and driverstoreexplorer.
Can you provide any help?
Thanks in advance, and for everyone that can help.
