Roblox game on Xbox one has no sound.

Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

First, welcome to the Xbox community.

Before we try any different solutions, please uninstall and install the game again, as you said it is the only game with this problem. If you have already done the uninstall proceed with the solution below.

Step 1. Press and hold the Xbox button on the console for at least 10 seconds to open the Power center.

Step 2. Then unplug the power supply from your console and wait for 3 minutes.

Step 3. Plug the power supply back into the Xbox console.

Step 4. Press the Xbox button on the console to turn it on again.

*If the alternative above doesn't work, I recommend that you contact the game's support, as it may be a problem with them, considering that it is the only game with this problem. To contact them use the link below.

Another good question to ask, while being an obvious one it is still something people overlook from time to time. Are you playing Roblox through the port of it on the Xbox One or are you trying to play it on PC through something like the Roblox website,
or in this case I believe the PC version of Roblox does have its own launcher akin to Minecraft. You'd need to be on the Xbox port of the game for achievements to work, I know that sounds like common sense but you'd be surprised how that can be a mistake sometimes.
