Waves Maxx Audio Pro not detecting any output device

Also, you might want to configure your xbox audio to Digital Stereo in case your PC can't encode audio formats other than the digital stereo format. See steps below:

Configure the console audio settings

Note The steps below might differ depending on the type of cable that you use on your console and the audio receiver or the output device that you use.

Start the Xbox 360 console without a disc in the disc tray.

Go to the Settings hub, and choose System.

Select Console Settings, and thenselect Audio.

Select Digital Output and then select the digital output used by your audio system:

this -> Digital Stereo

not -> Dolby Digital 5.1

not -> Dolby Digital with WMA Pro: This setting enables WMA Pro pass-through if your receiver supports the WMA Pro format.

Hope this helps.

Ok so you're getting audio from other sources on your TV? Try resetting your audio settings -

Go to Settings and select System.

Select Console Settings, and then select Audio.

Select Digital Output, and then select the digital output used by your audio system:

Digital Stereo

Dolby Digital 5.1

Dolby Digital with WMA Pro: This setting enables WMA Pro pass-through if your receiver supports the WMA Pro format.

If not, try a different HDMI port

Hi, in the display output settings on the Xbox check that you do not have DVI set. That only outputs video not audio. You should ideally have it set at Auto Detect or even HDMI if Auto Detect gives you issues.

This is just a guess, but I think your HDMI is probably set to "HDMI (Auto detect)". If so, try changing this to "HDMI" instead, then manually set your output resolution and your audio output again. Now the audio settings should stay put after resuming...

My Xbox One X has the same issue. I only noticed it doing it recently. I usually have HDMI audio set to output bitstream (DD), but on startup I will occasionally see it has change the HDMI audio output to 5.1 uncompressed. It's easy to notices as my
receiver will show as outputting Pro Logic II instead of DD 5.1 as it should when the Xbox One X is outputting a bitstream signal over the HDMI.

A power cycle does nothing. The only way to fix it is to go back into the audio setting and change it back to output bitstream over HDMI. It also doesn't do it every time the system is turned on. Sometimes it will turn on and remain on bitstream output as it
should.

Strangely enough I just noticed it doing this since i got a PS4 Pro. Almost as if going from the PS4 Pro's HDMI input to the Xbox One X's HDMI messes things up somehow. Though I haven't been able to find a situation where that can be replicated.

In any case....it seems ludicrous that a setting like that will just keep changing itself.
