No fix for suddenly having NO sound in XP11.30. Need help please

[gb]

I posted a few days ago that the sound suddenly stopped when I loaded a flight. There was a message that my system needed to be restarted...did that, no luck. Went online to forums, no help. No solutions.

Then, after the sound working then not working I uninstalled the Realtec audio drivers, reinstalled an updated version, no sound...then I reinstalled XP11 - even tho the files had no "verify integrity" issues, no sound... but every other game, video, music player, etc., works perfectly.

I can't find anything on the Xplane forum other than a suggestion I delete "preferences" and let the sim rebuild them. Did that...still no sound.

This is seriously frustrating. The sim is effectively useless at this point unless I can get some help. So....help!

Thanks...I did that and it makes no difference. Update - I just did a total reinstall again so the sim has no addons at all...and there is no sound! I'm getting really fed up...have been messing with this for 5 hours today.

As I answered in your other identical thread:

The issue is not with X-plane.

Realtek and other audio drivers use enhancement "filters" that rely upon tasks that the CPU must run to alter the audio stream.

Not only do these hurt FPS, but they very often interfer with games or cause no audio in games and programs. This is a common issue for people who use Digital Audio Workstation software too.

Open the Realtek control panel and disable ALL audio effects including reverb, acoustic enhancements, 3D, and even the equalizer.

Reboot and try again.

If that doesn't immediately fix it, you may need to toggle the option in the audio drivers that permits applications to take over exclusive control of sound.

OPJOSE - Hi- yes, I have done everything I can think of....reinstalling audio, even video, changing control settings for the audio panel, started with a clean install with no add-ons (just eliminating all potential issues).

Thing is, the sim had no isisues when I bought it then little by little I got the message that my audio had quit and to reboot the system. Then it got to where none of that made any difference. I'm familiar with the Realtek panel and have reset all options to factory settings, etc. etc.

It's driving me nuts and making me think there HAS to be some glitch with Xplane software because NO other application, game, etc. does this.

Setting the Realtek drivers to defaults causes this issue as it enables the sound enhancements and equalizer.

X-plane is not a DirectX program like most of the things that you are not having issues with.

X-plane uses OpenGl. The enhancements for the Realtek drivers, or something that may be opening the audio output before X-plane is run, is preventing X-plane from also using the audio drivers producing no output.

There are various threads here about this where I gave the same advice I gave you.

Disabling the enhancements or whatever may be opening audio output/input before X-plane has resulted in restored sound in X-plane in most of those cases.

You may also want to try deleting the X-plane preferences files to let it poll your computer all over again for configuration information.

Thank you very much for your continuing help. I need clarity re your comment about setting Realtek drivers to their defaults. I've tried setting the enhancments to ALL OFF which, if I am understanding it correctly, is the default. No sound either way, with or without them. But...from what I'm understanding, something may have been written to a file in prefs. Is that correct?

I will delete the preferences as you suggest, but please note that when I did a complete reinstall, they were all at default on the 1st startup.....I suppose they could have read the Realtek settings and that messed up the audio.

If you performed a complete re-install your original preferences may have been retained.

Usually this issue revolves around something outside of X-plane gaining shared or exclusive access to audio.

Don't forget to look at the settings under SOUND in the CONTROL PANEL.

NOT the sound settings in the Windows 10/8 "Action Center / Settings" pages.

Windows 8/10 has a bit of a split personality, with the more extensive functions being controlled on the older Control Panel as Microsoft's newer developers are trying to move away from the Control Panel.

In the Control Panel go to

Sound

Select your active output device, then click on

Properties / Advanced

And play with the two settings under "Exclusive mode". Remember to reboot after any changes.

While there check the other tabs to make sure all enhancements and equalization features are turned off.

Do you have a Virtual Reality Headset on your machine?

J'ai installé les mises à jour pour X-Plane 11-30. Depuis je ne peus plus télécharger le jeu !
Que faire ?

OPJOSE - Thank you once again, and no to having VR.

BUT....I evidently had downloaded an Nvidia audio driver that installed when I updated a graphics driver. I disabled it and the sound now works. I do appreciate your efforts to help! If this goes wonky I may come back to this forum and let you know!

That means there are no actual audio issues.

Your Nvidia card has the ability to pump audio output over HDMI directly to an attached monitor.

It can be a lower latency mechanism to produce sound, so Windows tends to favor it.

What happened was Windows did so, and you were not aware of the new target device (this is easy to check by putting the mouse over the speaker icon on the lower right, Windows will report the current output device in a pop-up balloon)..

As I mentioned something indeed took over audio output, in this case a different audio device.
