NO AUDIO - ASUS P5P800-VM Motherboard

If the RX-733 is similar to the RX-773 then the Audio 1 and Audio 2 ports are audio inputs on the AV receiver. The AV 5 and AV 6 ports are for composite audio/video connections.

I hope this helps.

How have you connected the audio cables to the TV? The 3250HD has component, DVI, and composite video out. There is also two analog audio outputs (for the component and composite video) and a digital audio output. Make sure that you are using a TV and not a monitor. Many monitors do not have built-in speakers. (In that case, use external speakers.)

If you use the digital audio output, make sure that your audio receiver audio input is connected to the set top box audio out. Then make sure to set the correct source for that audio signal. (Note the TV may have a digital audio port; that is an audio out.)

If you are using one of the analog audio outputs directly to the TV, make sure that you are using the correct set of audio IN on the TV and audio out on the set top box. (If you are on the Component input, your audio won't be heard if you are using the Composite audio output.)

Next try different audio cables. Make sure that the TV speakers are on. (Some TVs have an option to disable the speakers if you use external speakers at times.) Try connecting the audio output to a receiver and speaker system (or speakers with aux in). You might need an RCA F/F to 3.5 mm M adapter for some devices. If another set of speakers do not work, then the set-top box probably has a broken audio output. If another set of speakers work, then the problem is with the TV audio. This could be a problem with the jack or the speakers.

I hope this helps.

Check device manager if the Audio device is detected.

Check Audio device has mark like this ! - i suggest uninstall / reinstall the audio device driver. download the driver from dellsupport.com drivers and download page.

If the audio device has ? mark it means that computer not able to recognize the audio hardware. if you are using audio onboard replace motherboard. if the audio has expansion card reseat the card then try again. if all fails then try a different audio card if passed then the audio card is faulty. if all fails using a different audio card it means the motherboard slot is faulty. replace mobo.

Go to Device Manager and enable the audio card.
If you cannot enable the audio card or it is not working then install the audio driver again.

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.

copy and paste the above line into address bar press enter should take you to a site for your drivers
You will have to register but its free and useful if you need drivers in future

Audio not working means there must be a driver problem.Try to install the audio driver again.If it is high Definition audio driver first uninstall audio driver and high definition audio driver package.Reinstall the driver again.if problem persists check for the audio port.
