I feel like I bought one giant BUG

I bought a HTC Vive Pro a few weeks ago and I have not been able to enjoy one single session with it without dealing with bugs. I won't even go into all of them, the most common one is audio not playing through the headphone speakers. Googling reveals numerous people reporting the issue.

 

I've tried everything, installing and uninstalling the software, drivers, etc.

 

I keep the hub connected to the same USB port and don't connect or disconnect anything else from the computer. I select it to always play audio through the headset.

 

Next thing I know, it's back to the computer speakers. Then I select it back to HTC Vive, no sound. Then I have to either turn the hub on and off, or uninstall and reinstall the drivers.

 

To make matters worse, the engineers didn't even design a freaking test tone into the sound settings. Seriously?! So I have to keep trying to start a freaking game looking through the headset to do something that should create sound in the game, so I can troubleshoot! And I don't even invite guests to try it because it's going to be embarassing to have to spend 5-10 minutes getting the sound to work.

 

Laptop is Asus GL702V with GTX1080. Hard to put into words what a disgusting experience owning this has been, I feel like I threw away $3500. Hope there is a solution, very frustrated right now, every aspect of the purchase from beginning to end has been a bad experiece, this is just the biggest one. End of rant.

I'd suggest keeping the VIVE disabled in Playback Devices and just run an additional headphone cable alonside the VIVE cables from the Computer.  

 

I've seen this same issue with another 3D HMD display using HDMI.   The sound signal was often dropped if I loaded up a demanding title.  I found it was less frustrating to just keep the HMD disabled in the Playback Devices and run a cable headphone cable along with the HMD cables.  

 

You can also get bluetooth headphones pretty cheap these days.

Thanks, however I have the Vive Pro with integrated headphones, so I don't think running an additional cable is an option?

Re: I feel like I bought one giant BUG

Oh, didn't realize you were using the Pro.   My HMD with that issue also has large integrated ear cups and I wore small ear buds underneath.  Was annoying but solved the issue for the time being.    

 

Sorry I couldn't be more help.  I'd steer more towards the Laptop being the culprit in this issue, or whereever the HDMI cable is plugged in. I'm pretty certain its HDMI related since it sounds identical to what I was just  experiencing.

Re: I feel like I bought one giant BUG

The audio issue is likely a combination of how windows and SteamVR are interfacing together. I've seen this type of behavior across a range of hardware and software combos and overall the most universal solution is to use the "Playback Devices" to enable/disable your output devices as required. I typically disable  my laptop speaker, start SteamVR, and then reenable and mirror to it if required. 

 

On a side note, a current limitation of Unity that is it's not currently hot swappable with audio devices so Unity apps typically need to be restarted when adjusting audio configurations.

Thanks David, I will try those suggestions.

Where are you changing the audio source? Windows taskbar or SteamVR settings?

Re: I feel like I bought one giant BUG

I click on the little icon on the headset to open up settings, go to audio, and do it from there, which I assume is what you are referring as Steam settings (I thought it was Vive but same thing I suppose). In windows it always shows whatever I've set it to in steam.

However I followed David's advice last night and disabled all my other audio devices in Windows and low and behold, at least for that session, audio just worked!

So hopefully that solves the issue as I don't care about the other audio devices. I'll find out soon enough if it's a long term fix.

Re: I feel like I bought one giant BUG

Here is an update with the hope I can improve this (still existing) issue. If I just have the headset connected with no game playing and I go to the Windows volume control on the taskbar, the only playback device is "Speaker (Vive Pro Multimedia Audio)". I disabled the built in speakers so those do not show up.

 

However the moment I start a game, an additional playback device of "HTC VIVE Pro (NVIDIA High Definition Audio)" appears.

 

Is this normal - why do I have two different playback devices showing up for the headset? It appears that sometimes audio (for the headset) plays regardless of which playback device is selected, on other occasions it only plays on one of them, but not the other one. And sometimes it doesn't play no matter which one is selected..until I close and reopen etc.

 

I also notice if I disable the NVIDIA one it shows up again enabled.

 

Thanks

Since you can obviously replicate the problem, is HTC or Valve working to fix this, and the many other problems, that are plaguing Vive (especially Pro) users?

Re: I feel like I bought one giant BUG

We're currently looking into some bugs reported with the current Nvidia driver set; it remains unclear if they're related to your experience.

 

There exists two devices because you're able to select which driver handles the audio (USB vs DP). The same was true with the original Vive, except with HDMI. Depending on your configuration there are Pros/Cons to each option, hence why you're free to select either option. Removing the ability to select either option would result in a widespread support issue because some setups are dependent on the ability to choose the audio path.

 

Between the app, all of the middleware (SteamVR, Nvidia, onboard audio, ect...), and Windows settings combined with all of the hardware specificness (drivers, USB hosts, ect...) there are so many dropoff points unique to each PC that it can be very difficult to troubleshoot why things aren't automatically falling into configuration. I would still recommend sticking to manipulating the audio device panel when things aren't working automatically - It's the easiest way to simply disable a device that's interfering with the audio routing. I vary rarely use SteamVR's audio settings and only really manipulate Window's settings - it's much more reliable across a wider range of hardware and SteamVR won't be able to properly route audio if the underlying windows settings are incorrect. When using PC's that are stubborn, I typically just play music through the HMD using youtube so I verify from my keyboard that audio is being routed through the HMD before I walk over to put it on. 

 

 

Windows 1803 has introduced UI/UX  updates to the audio preferences which may be exacerbating the issue. The new update makes it more difficult to access these configuration pages.

 

It's also worth pointing out that a current limitation of the Unity engine is that it is unable to hot swap audio devices. You must restart Unity apps when you alter the output.

Re: I feel like I bought one giant BUG

Hi,  :robotmad:

 

I had exactly the same feeling about a week ago !  ( giant BUG  )  

My audio was not working properly.  Disconnecting issues .   Crashing issues .  Tracking issues .  Microphone issues .   Camera issues .   YOU NAME IT.      Now I don't have any of those.   Here is what I did ...

 

I created completely new partition on my hard drive JUST for vive pro ! I don't have anything on this partition but freshly installed windows 10 +  vive pro softwares.  I don't even have any antivirus programs.  Nothing !

 

Now everything works just fine. 

I am not saying this would solve your problems. I am just saying it did work for me and worth trying.

 

Yours,

Objectivity
