First of all you should check your internet connection. Discord displays your last and average ping in the bottom left corner, just click on "Voice Connected" and verify that your ping is behaving stable (if the red graph is stuttering a lot that means it's not stable!) and the last as well as the average ping is below 250 milliseconds. If both of these indicators show that your connection is bad you should try and check your WiFi/LAN. Restarting your router could also clean up some problems.
You're on a 5ms ping and you can download GTA 5 in 2 minutes?
So your internet connection seems not to be the problem. In 95% of the cases where Hydra is lagging Discord is having temporary issues with their voice servers. They normally just restart them at some point but you could force a switch to a different server in your region. In order to guarantee a smooth user experience we made a custom command for that! Just paste .fix in any text channel and wait for Hydra to cycle through a few voice servers to get a stable permanent one.
If that doesn't help you should follow the steps below to permanently switch to a different server region.
First open the server settings in your Discord server.
Click on "Change" to open up a selection
Select a new server region
After following all these steps you should finally have a lag-free audio stream again. If this is not the case please join our support server and check our #status channel for any ongoing incidents. If you can't find anything in there please get in contact with one of our support members.
