I googled my issue and the few notes I found didn't help me, so I'll put it here. TL;DR - See bottom of post for the fix Scenario: I have 4 razer products total: Kraken 7.1 V2 BlackWidow Chroma V2 DeathAdder Chroma Firefly Software of importance: Windows 10 64-bit. Newly installed (about a week or two old) Synapse 3 Beta - Unsure of what version. Was updated last 2018-11-01. VLC Media Player Audacity TeamSpeak3 Sea of Thieves The issue: Out of the blue I lost the sound on my right earpiece. Details: I was using the computer just as normal. Playing games, browsing the web, listening to music. I then decided to start editing some sound clips. I obtained an MP3-file to work with. I checked it's quality by simply run it with windows built-in media player, and it sounded good. I then proceeded to install VLC Media Player from their official website. I ran the file again and it still sounded as expected. I installed Audacity from their official website. I opened Audacity and dropped the MP3-file inside of the program window. Once I hit "play", I could only hear the sound in the left earpiece. I briefly tried to find some settings inside Audacity that would explain this. I didn't find any of use. I gave up and logged on to a Teamspeak-server to chat some and start a session of "Sea of Thieves". Once on TS3 I realized I still only had sound on left side. Same thing in SoT. Game only gave sound on left side. I then disconnected the headset and checked sound on my speakers (3.5mm plugged into the BlackWidow). On the speakers I had sound on both channels. I reconnected the headphones, still only sound on left side. I tried a different USB-port. No change. I rebooted the computer. No change. I uninstalled Audacity. No change The fix: Today I uninstalled Synapse 3, as well as all forms of drivers for my Kraken 7.1 V2. I installed Synapse 2 with the headset disconnected. Once everything was upto-date and logged in, I connected the headphones. Synapse 2 prompted for an update, which ran fine. A reboot was required. Once the computer was rebooted. The sound was back to normal on both earpieces. Problem solved. Sadly I have no logs. I'm not blaming Audacity (or anyone else really). I do not know what caused the issue I'm just posting here so that anyone who experience a sudden loss of a channel can find some aid in fixing it.
