1. when i watch dvds from nero essentials and play videos and files from windows media player, but when i watch youtube videos, and watch videos from flv player, there are no sounds!

2. i have tried the windows audio service troubleshoot, but apparently, my windows audio has started and is running.

3. i used to have c-media mixer and soundman.exe running on the tray, and when i double click it, it says, i have no active mixer. and that i have no audio device. now, i disabled both on my startup. sndvol32.exe also says i have no active mixer.

4. i can't hear system sounds as well, like the opening sound of windows and such.

5. i am using realtekac97, and i am using an onboard sound card. it seems i have the right driver, since i'm able to hear sound from windows media player, but no sound from flv player! weird!

i have googled a lot of forums already but i have never encountered anyone which has the same case as mine! any help would be appreciated. thanks!

A concise diagnosis and targeted next steps, building on 's driver/default-device direction and 's symptom report.

Recommended checks (in order)

  1. Inspect Device Manager for any sound devices or unknown devices and note their hardware/vendor IDs. If Windows only exposes the modem as a multimedia endpoint, temporarily disable or uninstall the modem device so the onboard audio can be re-enumerated.
  2. Clean out any mixed vendor drivers (do not keep both C‑Media and Realtek installed). Use Add/Remove Programs and Device Manager to remove audio drivers, reboot, then install the chipset-specific audio package from the motherboard/vendor web site (not a random generic pack).
  3. Run the DirectX diagnostics (dxdiag) and review the Sound tab for the listed device and test tones; save the dxdiag report for comparison.

Flash/FLV and plugin-specific checks

  • Play the same FLV locally with a standalone player that bundles codecs (VLC or the FLV player). If local playback has sound while browser/Flash does not, the problem is likely the browser/Flash plugin rather than core drivers—reinstall the Flash plugin and try a different browser.
  • If the standalone player also has no sound, the issue is system/driver level.

Quick fallbacks and cautions

  • Try a cheap USB audio dongle or PCI sound card to rule out a dead onboard codec.
  • Avoid installing multiple vendor drivers at once; conflicts can register the wrong mixer and leave the system mixer reporting "no active mixer".
  • If these steps are not conclusive, capture and post the Device Manager entries (or the dxdiag output) so the exact vendor/device IDs can be used to identify the correct driver.

in control panel open sound and audio, go to the audio tab and ensure all are using the same devices and check use default devices only. then open volume control and click on options then properties ands select the correct mixer device and put a check mark beside midi. then adjust the volume according. as for the windows audio you have to select a audio scheme to use, on the audio and sound select the sound tab and choose a sound scheme to use for windows.

thanks for the reply!

1. i was able to do up until the 'check use default device only'. the defauld device for sound playback and sound recording is 'Modem #0', which i'm quite sure of, is not my sound device. i have built-in modem in my motherboard. note also, that i have 'No audio device.' in the sound tab.

2. the volume control is not displayed in my system tray.

3. in the sounds tab, when i press 'Play' to hear any windows sound, for example, Asterisk, this message pops: Windows cannot play the sound %SystemRoot%\media\Windows XP Error.wav. Your sound card may be in use.

thank you!

Do you have a build in sound card or a PCI card.
get the latest drives for it and install. as for the sound and playback change that from modem to the name of your card.
as for not able to play sound because device is in use. the update should fix this. some other program that uses the sound channel does not realease, after finish using it, hence the error message.

thanks for the reply!

1. windows is actually confused with the build of my sound card driver (if you are referring to the make/model and stuff) it initially detected that i have a C-Media AC97. i got the proper drivers, but it didnt work. after googling, i found out that i may have the Realtek AC97 sound card. i installed the drivers and got sound for WMP and Nero Essentials. but no sound from FLV player and windows. seeing this, i have the latest drivers from Realtek AC97. or is it possible, i have the wrong driver and it's neither C-Media nor Realtek?

2. for the sound playback and recording, the only option in the list box is the Modem #0 as windows says i have no audio device.
