Audio device not found

Check:-
1. The Stereo Mixer volume control is not turned down, under the speaker icon on the desktop, or via the sound icon in the control panel.
2. Under the sound icon the audio jack is not disabled or needs a driver to make it work. Both of these can be solved by running the device manager in Control panel.

If there is a driver needed ?

Click start control panel administration tools computer management device manager scroll to sound video and game controllers you might see a yellow question / exclamation? ! mark or a red X Right click to reinstall drivers
If your computer came with a motherboard disk the drivers could be on it
or you might download slimdrivers.

The headphone jack on the computer connects to the sound card, a hardware device that controls audio input and output on the PC.
The card contains a digital-to-analog converter that converts analog audio into digital signals and visa-versa.
The performance of the headphone jack, therefore, depends on how well the sound card functions; if the card doesn't work, then the headphones connected to the PC won't output sound.
Reconfiguring the audio settings will often fix problems with audio output on the headphone jack, but if the former fails to resolve the issue, replacing the sound card in its entirety is sometimes the only means of repair.
Click "Start." Enter "sound" into the search box. Select "Sound" from beneath Control Panel.
Double-click "Headphones."
If no "Headphones" option is available, double-click "Speakers."
Click "Properties" on the General tab.
Check the Device Status field for errors. Look up the message on Microsoft Support for more assistance, if applicable.
Close the window if the Device Status field reads "This Device Is Working Properly." Go to the "Levels" tab.
Click the speaker button to unmute the volume if the icon contains a red circle-backslash symbol. Drag the top slider to the right to increase the headphone volume.
Go to the "Enhancements" tab.
Check "Disable all Sound Effects." Go to Applications, and then clear "Allow Applications to Take Exclusive Control of This Device."
Click "OK" to close Headphones Properties or Speakers Properties.
Test the audio.
If the headphones fail to output sound, unplug the headphones from the computer.
Reconnect the headphones to the PC.
Headphone jacks are color-coded lime green on most PCs.
Look for the headphones symbol if the jacks are not color-coded.
Plug the headphones into the line-out port on the back of the computer if the headphone jack on the front of the PC fails to work, or visa-versa.
Test the headphones.
If headphones still won't emit sound, the sound card most likely requires replacement.
Replacing the Sound Card
Shut down the computer. Remove the power cord from the back of the PC.
Disconnect the keyboard, mouse, monitor and all other peripheral devices.
Loosen the screws found on the back of the case, then slide the cover panel off of the case. Touch the chassis to protect the hardware from electrostatic discharge, or ESD.
Set the computer on its side.
Locate the sound card found on the opposite of the audio jacks and loosen the screw that secures the card to the computer.
If no expansion card is located opposite the jacks, the computer uses an integrated sound card which can't be removed.
Remove the new audio card from its protective packaging.
Line up the card with an available expansion slot on the motherboard, then push the card down into the slot to install the new audio jacks.
Screw the card to the computer case.
Reassemble the computer.
Turn on the PC. Boot in to Windows and insert the CD that came with the new expansion card. Follow the onscreen instructions to install the sound card software to the computer.
Plug the headphones into the new line-out jack.

see i guess your audio jack is short in any kind into the board, please try to change the profile from headset to general (or any other) second try with audio jack inserted (some time it done if some little shortage from audio Jack) if both not work then you need to take some help of professional they will remove the "shortage of headset"



vote me if found helpful.

check wiring to the front panel it sounds like it is not plugged into the right jack on the motherboard.

the connector is marked F_audio and it is located directly behind the rear facing audio jacks. should be only one plug either marked "hd audio" OR "ac97 audio". some cases are setup for either, but you only need one of them depending on what your motherboard supports.

11) F_AUDIO (Front Audio Connector)
This connector supports either HD (High Definition) or AC97 front panel audio module. If you wish
to use the front audio function, connect the front panel audio module to this connector. Check the pin
assignments carefully while you connect the front panel audio module. Incorrect connection
between the module and connector will make the audio device unable to work or even damage it.
For optional front panel audio module, please contact your chassis manufacturer.
By default, the audio driver is configured to support HD Audio. To connect an AC97 front panel
audio module to this connector, please refer to the instructions on page 72 about the software
settings.

Onboard audio is disabled in the BIOS
The BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. Go to the Advanced > Peripheral Configuration menu to make sure onboard audio is enabled.
Audio settings in the sound mixer are incorrect
Check your audio mixer software to ensure audio is not muted or the volume level is not turned too low.
The speakers or headphones may be connected to the wrong jacks
Make sure you connect all speakers to the correct jacks. If you connect them to line-in or microphone jacks, they won't work.
Audio drivers are not properly installed
Check Device Manager under the Sound, video and game controllers section for any errors associated with the audio driver. Reinstall the audio driver if necessary.
Audio to back panel is muted if front panel is connected
Check your audio mixer software for a setting that mutes back panel audio if you have plugged headphones into a front panel audio solution. Uncheck this setting to allow audio to both the back and front.
Sound Playback is set to wrong device
In Control Panel > Sounds and Audio Devices, go to the Audio tab. Check the default device for sound playback; there may be multiple selections. Select the desired device, either rear panel or front panel.

translated for me GreenGo using google translate
The front audio and the microphone are disconnected not if it is connected in the panel and if so I would like to know how,
(the book is free to read at Asus.com 24/265) no need to guess.
Asus is #1 maker in the world. top documentation from 1995 to now)
because the number of cables that I have to connect is greater than the number of empty pins, I do not know if it has a color relation, or of positive with negative in order I would like to know the exact place of each cable.
stop counting pins,ok some pins there are only For factory testing. see long answer below. with links


Would I have to disconnect the rear audio from my PC?
well the jacks can not be unsoldered?
or do you mean unplugging 3.5MM jacks to mic, AMP or phones or speakers?
I hope not. If, besides the written explanation, it could have a graph, it would be perfect. \The manual guide that I have has not been sufficient for my purpose. Thank you for this opportunity.
your are most welcome but the manual is clear as day to read
but is in like 10 languages,
I'm typing now on a ASUS, Z270 prime right now,
mine has front and read audio jacks, and the BIOS controls those features, and that too is in the rear of the manual,
now here is your manual,

BTW; first google hit,
https://www.asus.com/supportonly/P4P800-E%20Deluxe/HelpDesk_manual/

and the manual in Spanish is only in the Multilanguage PDF
Do you have PCI- cards?
this mobo (motherboard) is relic, 14 years old today.
learn that in computers and in electronics, all this that you are doing is complex. MOBO have polarities, Plus + and minus -
Many connectors are keyed, that make them fit only 1 way.
see page 11 for Espa?o
the FANS are polar. as are USB, main DC, and lots more.
the lower right connectors are all POLAR.
https://dlcdnets.asus.com/pub/ASUS/mb/sock478/P4P800-E%20DX/u1526_p4p800-e_delux_qsg.pdf

do not connect anything to the mobo, with the AC PSU power supply connect to wall AC power, ever, DO NOT.
that is called hot swapping, do not HOT swap things inside the case.

audio jacks, ?
Realtek® ALC850 8-channel CODEC Audio Sensing and Enumeration Technology S/PDIF out interface support (my guess not used by you) spec, on audio chip. is this.
the rear jack is multichannel sound , 4,6 and 8 channels !
page 2-24 (English manual)
the FP_audio jack left rear is Front Panel.
(10-1 pin FP_AUDIO) page 2-34.
12. Front panel audio connector (10-1 pin FP_AUDIO) This is an interface for the front panel audio cable that allow convenient connection and control of audio devices. By default, the pins labeled LINE_OUT_R/BLINE_OUT_R and the pins LINE_OUT_L/BLINE_OUT_L are shorted with jumper caps. Remove the caps only when you are connecting the front panel audio cable. now your 1 questions clear as day same page
The Front panel audio Line-Out connector and the Rear panel Line-Out jack can not work simultaneously.
to use only the 2 channel front panel jack
you must remove the 2 blue jumpers on the FP_audio jack.

and last do not connect any wires inside the PC backwards
wrong polarity.
nor run the CPU with no heatsink or missing or dead fan.
Salud.

I found many references to this issue but I am not sure which may apply to your problem. Here is a set of steps to follow from another site: (Assumes Vista and Realtek)

• Open Vista’s Control Panel (Window | Control Panel)
• Open the Realtek Audio Manager (not “Sound”)
• In the navigation bar in the far right, there is a little yellow folder icon. It is just below “Device advanced settings” and above “ANALOG”. Click the folder icon.
• Click “Disable front panel jack detection” so that a yellow check mark shows up. Hit “OK”, and close the Realtek HD Audio Manager. That should re-enable the sound

hi!gud am...hope this will help...

have you check if your audio controller is working?have you installed the driver?if not check this out...start>control panel>system>hardware>device manager>sound,video and audio controllers...

is your mic and earphone new?if not try to replace it with a new one maybe its broken that's why its not working...

check if the front panel audio is connected on your mobo...some casing with front panel audio has no connection...let me know what you see and tried ok?

goodluck...
