    Audio not outputting with Vizio TV


      Hi I got my compute stick yesterday. I hooked it up and everything loaded up fine, but there was no audio from my Vizio P652ui-B2.


      Windows recognizes the TV as the audio device when you drill down on the Sound properties. When I run the test no sound comes out. Driver perspective and OS it looks like everything is recognized but just no audio. Has anyone run into this?


      I haven't had much time to troubleshoot. I have switched to other HDMI port and rebooted. Same behavior, but I think it is an issue w/ the device outputting to a certain channel that the Vizio can't pick up?


      Thanks in advance for any suggestions

          I am having the same problem.  This is not a problem with either the TV or any individual Compute Stick, this is a compatibility issue that is beyond my level of knowledge.  I have tested both my TV and compute stick with other TV's and they both work fine.


          We need intel to look at the drivers and potentially how the sound it translated through the HDMI port to the TV.  Intel, please look into this and give us an estimate on when this will be resolved.  If I can't receive at least an estimate and acknowledgement of the issue within the next week, I will have no choice but to return the device - and warn other consumers of this incompatibility.  I really like this computer so far, but it is unusable to me where I want to place it!  Thanks for your help.


          Also please understand that this issue is far wider than these forums would indicate, and you are currently experiencing an impact to your sales because of this, in addition to future sales.

            Argh. That was actually what I was suspecting. I chatted with an Intel rep today and got a case number. I haven't had a chance to try with other monitors and do your level of validation but I mentioned to the rep that my TV is pretty much built for this kind of usage with 5 HDMI ports. My chromecast works fine etc.


            I would concur that its likely a driver issue in how the sound is being outputted through the HDMI port. Do you have the same TV as well?


            The rep asked me to try installing the latest BIOS as well but I haven't had a chance to check and see which version I am on. Have you tried that as well?

            • 3. Re: Audio not outputting with Vizio TV

              I will check the BIOS now.  I will say that the TV I am having issues with is also a Vizio 4k TV,  give me a few minutes to respond with my BIOS version.

              • 4. Re: Audio not outputting with Vizio TV

                I had issues trying to get into the BIOS by hitting F2. I tried cold boot and restart and am unable to get in. Were you able to?


                I also played with the Vizio audio and system settings to see if that would get it going but no go.

                  any luck on your end? Did you get into the bios?

                    I suggest you to download and install the latest graphics driver of Intel® Compute Stick STCK1A32WFC, version

                      HI mike,

                      I have installed the latest BIOS and video driver on my device.


                      Seeing how this is still an issue, and I didn't hold up my end of the deal by trying to install the latest bios and driver I will give you guys another week to acknowledge the problem and begin working to resolve it.


                      My tv:  p5002ui-b1e

                      version 1.1.19

                      audio type: frc version: 9.248


                      Please acknowledge the issue and confirm your companies ability to reproduce it.

                        Hi Mike


                        I installed the latest graphics driver and still audio does not work. If anything I need updated audio drivers.


                        Can Intel verify this behavior on Vizio TVs in general? That might help get this moving.

                          Hi all,


                          This is a known issue with some Vizio models, and other manufacturers as well. The Compute Stick team is currently working with the graphics/audio driver team to get an updated driver version to fix this problem. I don't currently have an ETA on when that will be available, however.

                            I tested in our lab the Intel® Compute Stick STCK1A32WFC with the Samsung model CY02 TV without any problem. I just used the compute stick and the TV, no adapters, no home theater or any other accessory.


                            Please perform the following test. Create a back up of your documents and make a recovery of your operating system tapping F8 while the stick reboots.

                            It might sound very basic but please make sure the TV is set as default Audio device.

                            Right click the Audio icon on the lower right corner of your display, select playback devices and select your TV.

                              Thanks for the acknowledgement Lois.  I look forward to the new driver that will solve this issue, any chance we can get a beta driver?  I have had other companies give out beta drivers when incompatibilities are making the product unusable.

                                Hi Lois,


                                That is great news! Can you please keep us updated on the progress of the driver? Do you know when work was started on it?





                                P.S. Looks like I am being moderated as well now.

                                  Hi Leftside,

                                  You haven't been added to a list of people needing moderation. It's something in our moderation engine that isn't working perfectly. I'm sorry that you are experiencing these moderation delays. We are working on improving the moderation engine, but I don't expect any changes to what you see in the next few weeks. We would turn moderation off completely. Unfortunately, there are spammers that will flood the forums if we turn off moderation.

                                    Hey Lois,


                                    Can we get an update on the drivers status?  It has been a few weeks since we have heard anything and I am sure others are getting antsy along with myself.


                                    I noticed an unsigned driver posted to the windows support downloads page that was released on 7/17/15, so I installed it in hopes that it would solve the issue.  Unfortunately, this didn't help at all.  So basically just looking for an update.
