A compact, practical checklist to isolate why a new Vista PC has no audio. The items below move from noninvasive settings checks to hardware isolation so the cause (Windows config, DVD codec/output, or hardware/wiring) can be identified without unnecessary tools.

  • Verify playback routing: open Control Panel -> Sound -> Playback and confirm an analog "Speakers" device is present and set as Default Device. If only a "Digital Output" or SPDIF device is active, audio may be routed to optical/coaxial instead of the green analog jack.
  • Confirm per-application and system volumes in the Vista Volume Mixer so a player or system sound stream is not muted.
  • Check Windows audio services (services.msc): Windows Audio and Windows Audio Endpoint Builder should be set to Automatic and running.
  • Inspect Device Manager -> Sound, video and game controllers for disabled, generic, or error-marked devices. If the driver is incorrect, uninstall the audio device (choose the option to remove driver software if offered), reboot, then install the vendor-supplied Vista driver for the exact Acer model.
  • In the audio manager (Realtek or similar), ensure analog output is selected, set the default format to 16-bit/44100 Hz, disable enhancements/jack-detection if it falsely detects a front-panel device, and check that output is not forced to S/PDIF.
  • DVD-specific: some players bitstream Dolby Digital to SPDIF only. If video plays but no DVD audio is heard through analog speakers, try a player with built-in decoding (for example, VLC) so audio is decoded to stereo PCM.
  • Hardware checks: test known-good headphones/speakers on the rear green jack, swap cables, try a USB sound adapter. As a deeper test, boot a Linux live USB—if sound works there, the issue is Windows/driver related; if not, suspect hardware or BIOS settings.

This follows the driver-theme from and offers a free/manual alternative to the paid utility mentioned by . If the onboard audio still appears dead after these steps, contact Acer support while the machine is under warranty rather than opening the case.

one of the upgrades Windows made with vista was reducing all audio drivers to two categories... maybe you should investigate about it... but, if you bought it with vista installed, i can't see why there should be any problems... maybe you should contact tech support...

Try using driver detective its $29 but gives you automated links to the correct driver website and lets you know if you have the correct drivers installed, I am dual booting with Vista Home Premium and have been ok with my sound and all other drivers, Good Luck
