[SOLVED] Razer Kraken 7.1 V2 - Lost sound on right earpiece

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.
