![]() ![]() If you can't perform the Wi-Fi Direct or Screen Mirroring function, check the following: Before you start For Wi-Fi Direct and Screen mirroring: Video, photo, and music content can be streamed from the device directly to the TV without the use of a wireless network. I also met the same problem.The Wi-Fi Direct® and Screen Mirroring features allow wireless peer-to-peer connections from a source device to the TV. Even if it is a sample of nothing. If Microsoft would include this as part of the process, then it seems it would fix the issue. So the problem seems to be that windows needs to provide a audio sample audio during the handshake to establish what "normal volume" should be. I LITERALLY PLAYED A FILE OF NOTHING AT ALL WHILE CONNECTING. I then played it while connecting to the ROKU, and then played a video after it was connected, and the sound from it was fine. I tested this by creating a silent audio track that has absolutely nothing that will transmit at all, it is literally a straight line with no frequencies or wave forms what so ever. (2) HOWEVER, if you play anything that has an audio track at full computer volume, the handshake proceeds as it should and all audio play as it should. When the handshake happens between the Windows 10 computer and the ROKU, (1) if no audio track is playing, when the computer then plays audio something like the simpsons vid happens on the ROKU end, and it gets blown by MASSIVE clipping. Ok, now that you know what clipping is, go watch a video on youtube called "simpsons megaphone testing", its very short. Have you ever heard a recording that you could easily hear, but was just out of wack like it had been run through some gravel or something? Go ahead and look up clipping in another browser tab. Now to understand what is happening, you need to know a little bit about an audio problem called "clipping". Apparently this was triggered by an update. Basically there is an error in how windows does this with ROKU devices. Whenever two devices connect to each other, the is a "handshake" process where each exchange information about how and what information they will communicate. If all that fails, then the following may help, though it is referring to distorted audio. Next try different settings in the audio of the ROKU. So I have thoroughly investigated the audio problems, tried every "fix", and here is the issue as I see it:įirst try to test all components of your computer, update drivers, and perform troubleshooting steps. Now check if you're able to use the both device at same time. Select your HDMI device from the "Playback through this device" list.Click on the " Listen to this device" checkbox.Double click on the new device to open the Properties window.Right click on the new device and click " Set as Default Device".Right click on the new device and click " Enable".A recording device called " Wave Out Mix", "Mono Mix" or "Stereo Mix" should appear.Go to the "Recording" tab, right-click and enable "Show Disabled Devices".Select Speakers as the default playback device. ![]() Press Start, type Sound into the search space and select same from the list.Try the below steps and check if they helps. The following solution, I accidently found during a Google search, is posted below so that other people could benefit from: I had the same kind problem using Roku Miracast, which indicates video working fine onto TV, but audio not working with static noise. That being said, if you've otherwise configured your TCL Roku TV as I outlined above, then:ġ) Try connecting the TCL via wired or to a 5Ghz SSID - there is a known RokuOS bug (in recent builds of 9.3.0) when Roku streamers are connecting to 2.4Ghz SSIDs that prevent Miracast (and other) connections with more recent Android/OneUI/SmartView device (phone/tablet/etc) versions (older Android/OneUI/SmartView versions work fine however).Ģ) If your wireless gateway/router/modem/device doesnt have separate 2.4Ghz and 5Ghz SSIDs, configure it so it does (so that you have more control and allowing you the above recommended configuration).ģ) If your wireless gateway/router/modem/device only has 2.4Ghz frequency range, consider upgrading/replacing it with a dual-band (both 2.4Ghz and 5Ghz) one (soon triple band will become available).Ĥ) Report the Miracasting issue to both TCL and Roku (and to your phone/device manufacturer too): Samsung phone screen appears on Roku TV screen as well) are two different technologies/protocols/processes. NetFlix on Phone controls NF on Roku) and Screen Mirroring/Sharing (device screen appears on other device screen e.g. "Casting" (device app controls other device app e.g. ![]()
