Audio output device - Microsoft Windows Vista Home Premium with Service Pack 1: Windows

If you need an analogue output, you can tap stereo analogue audio by using one of the two sets of "pre-out" RCA jacks on the back of your receiver. These provide "headphone like" output power, and will not overload any analogue input connected to it EXCEPT MIC and PHONO inputs on the 2nd device. If it's digital audio output you need, there's an HDMI monitor out, that will provide digital audio to another HDMI input equipped device. You'll have to get a relatively cheap adaptor if you need this digital audio output in another digital format/connection (like the popular S/PDIF optical or coaxial).

Hello,

A HDMI cable can output both audio and video, whilst some computer with Windows XP cannot automatically switch to HD Audio output as Windows 7 can. Thus manual setup can solve the problem.

After connecting the HDMI cable, Go to "Start" > "Control Panel" > "Sounds and Audio Devices", double-click "Sounds and Audio Devices. Select "Audio" tab on "Sounds and Audio Devices Properties" window.

On "Sound playback", change "Default device" from "Conexant HD Audio output" to "NVDIA High Definition Audio".

Your television should have several HDMI ports, select the appropriate HDMI port number and check if TV is not muted.


Hope this helps.

Well it is possible that the audio driver installed is not the one compatible with you computer board. Try downloading the specific driver needed for your computer's official website. This should solve your problem.

You have to install the audio driver for the audio device first. As for the output audio it is for speakers connect/plug into to the output audio port.

For no Audio output device installed message, go to device manager uninstall the audio driver. Reinstall the audio driver from either Windows update or from the manufacturer's(your Computer or Laptop) Web site.

Hello,

Adjust the system's audio output settings. These settings are mainly used when the system is connected to audio devices that support digital audio output, such as AV amplifiers (receivers) for home entertainment systems.
1.
Confirm the formats supported by your audio device.
Settings vary depending on supported formats. For details, refer to the instructions supplied with the audio device.
2.
Select (Sound Settings) under (Settings) in the home menu.
3.
Select [Audio Output Settings].
4.
Select the input connector on the audio device. Channel numbers and audio formats that are supported vary depending on the connector in use.
Input connectors on the TV or AV amplifier (receiver) PS3™ system output connectors Channels that can be used for output 2 Ch. 5.1 Ch. 7.1 Ch. HDMI HDMI OUT connector Digital Out (Optical) Digital Out (Optical) connector - Audio Input Connector / SCART / AV MULTI AV MULTI OUT connector - - 5.
Select audio output formats.
Select all output formats that are supported by the audio device in use. If [Audio Input Connector / SCART / AV MULTI] is selected in step 4, the screen for selecting audio output formats will not be displayed. If [HDMI] is selected, you can also select to automatically set the audio output format. (In this case, the HDMI device must be turned on.)

The audio output settings are saved on the system.
Hints

• [Linear PCM 2 Ch.] audio is set to be output from all output connectors by default. If you change the audio output settings, audio will be output only from the connectors that were set.
• If you change the audio output settings, the system will no longer be able to output audio from multiple output connectors at the same time. For example, if your system is connected to a TV via an HDMI cable and to an audio device via a digital optical cable and you switch to [Digital Out (Optical)] under [Audio Output Settings], audio will no longer be output from the TV. To output audio from the TV, switch the setting to [HDMI], or select (Settings) > (Sound Settings) > [Audio Multi-Output] and set the option to [On].
• If you select [Linear PCM 2 Ch. 88.2 kHz] or [Linear PCM 2 Ch. 176.4 kHz] in step 5, sound may be intermittent or may not be emitted from some audio devices.
• When using an HDMI cable, only [Linear PCM 2 Ch.] audio will be output from PlayStation®2 and PlayStation® format software. To output Dolby Digital or DTS audio, you must connect the PS3™ system and the audio device using a digital optical cable and switch to [Digital Out (Optical)] under [Audio Output Settings].
• If a device that is not compatible with the HDCP (High-bandwidth Digital Content Protection) standard is connected to the system using an HDMI cable, video and/or audio cannot be output from the system.
