Razer BlackShark V3 Pro – Random Audio Cut (Chat Endpoint Investigation)

Issue Description

  • Audio randomly cuts out during gameplay (mostly CS2).

  • The headset remains powered on.

  • There is no disconnect/reconnect sound.

  • Windows does not show the device as disconnected.

  • I must power cycle the headset to restore sound.

  • Gameplay recording still captures both game and Discord audio even when I cannot hear anything from the headset.

Key Observations

  1. When audio cuts out:

    • Windows still shows the device as active.

    • No USB disconnect event occurs.

    • No RF disconnect sound is heard.

    • Recorded clips still contain full game + Discord audio.

    ➜ This confirms the PC audio stream is still active.

  2. The issue appears more frequently when using:

    • BlackShark V3 Pro – Chat endpoint for Discord.

  3. When switching Discord output to:

    • BlackShark V3 Pro – Game

    The audio becomes:

    • Noticeably louder

    • More stable

    • No random cut so far

  4. When disabling and re-enabling:

    • THX APO 4 Component

    Discord volume suddenly increases significantly.

    ➜ This suggests THX APO is actively affecting gain levels and may enter an unstable state.

  5. At one point, the Chat endpoint volume in Windows mixer was separately reduced.
    Increasing it manually restored normal volume.

Troubleshooting Steps Performed

  • Disabled THX Spatial Audio

  • Disabled ANC

  • Disabled Low Latency mode

  • Disabled USB power saving on all USB Root Hubs

  • Switched USB ports (rear motherboard ports tested)

  • Removed SteelSeries Sonar and related APO components

  • Fully uninstalled Razer software

  • Removed THX APO components

  • Tested with pure Windows generic USB audio driver

  • Verified that USB disconnection is not occurring

  • Verified that the PC continues producing audio during failure

Important Technical Findings

  • This does NOT appear to be a USB disconnect issue.

  • This does NOT appear to be an RF drop issue.

  • This does NOT appear to be a complete driver crash.

  • The issue seems isolated to the Chat endpoint behavior and gain processing.

The Game endpoint works normally and appears more stable.

The Chat endpoint:

  • Has independent volume control in Windows.

  • Is treated as a communication device.

  • May interact with Windows communication attenuation.

  • May be affected by THX APO gain processing.

Current Working Configuration

  • Windows Default Playback → BlackShark Game

  • Discord Output → BlackShark Chat (currently testing)

  • Communications setting → “Do Nothing”

  • THX removed

  • No additional APO layers active

Testing continues under clean driver conditions.

Main Suspicion

Possible instability in:

  • Chat endpoint processing

  • THX APO gain handling

  • Dual-endpoint communication routing behavior

Since recordings continue capturing audio normally, the failure seems to occur after the PC audio stream — potentially at the endpoint processing or headset firmware level.

If anyone has experienced similar dual-endpoint instability or gain reset behavior with BlackShark V3 Pro, please share your findings. I am trying to make an app to figure out why it happens. So far I believe there is no pyshical issue on the headset.

    From my experience, when the audio drops, you can also wait about 120 seconds instead of turning the device off and on. After that, the audio will start working again.

      Got this headset last week and this has happened to me twice already. Very annoying.

      bought this headset a few weeks back as well and this is genuinely such an annoying issue…. and razer just refuses to acknowledge this issue, nice.

      This issue has started for me in the last few days, purchased October 2025 and have had no issues until now.b

        I've also started having these issues in the last two weeks or so, headset is ~3 months old. Any known fixes?

          This just happened to me while playing DOOM: The Dark Ages with a BlackShark V3 (non-pro). Cycling the power fixed it for me as well.

          I can’t even imagine having this issue crop up in a crucial match in CS2, Overwatch, or any competitive shooter. Good thing I’m mostly a singleplayer guy these days, because if it happened to me in the middle of a multiplayer match I’d be liable to throw the headset right out the window.

          I'm experiencing the same random audio cut issue. The headset stays connected and Windows still detects it, but all sound disappears until I restart the headset. Your findings about the Chat endpoint and THX processing are really interesting. I hope Razer can reproduce this and release a firmware or Synapse update to fix it.

          Razer Blackshark V3 Pro user here too with the same issue, I can confidently say this happens at least once a day.

          To add to JohnWorthy’s findings: It seems to mainly also only affect the output endpoint, others should check as well but for me, mic input still works, people in Discord for example can still hear me after I lose audio output.

          Also I have to agree that the Chat output volume sync is total trash, it does not stay in line with the game endpoint, despite ducking (communication mode/attenuation) disabled. I use a third party app (Arcitec/VolumeLinker) to link the chat volume to the game endpoint volume, which works great but is still just a workaround.

          Razer synapse: 4.0. [removed by moderator]

          Firmware version: 1.3.3.0

          Model number: RZ04-0540 0100

          To note, I do use an additional APO layer (EqualizerAPO), both on the input (mic) and output (game+chat) endpoints, but the end result is the same.
