I would've just ditched Link altogether at this point, if not for vastly superior video quality and lower latency with Oculus Link. But, today I've managed to test ALVR, on open source alternative to Oculus Link (it works via USB cable, too) - and it has no audio crackling whatsoever, it's perfect. My very long and futile exchange with support ended with nothing several months ago, so no, no fixes.

I created a support ticket #3596583 but they just sent me to SteamVR support (via incorrect link, btw) despite this being a problem not specific to SteamVR apps.

Different combinations of checkbox values in Oculus Virtual Audio Device speakers.

Changing priority of process OVRServer_圆4.exe to High.

Connecting over AirLink using 2.4Ghz router - the same crackling noise.

Removing all USB devices in Device Manager and restarting Windows.

This also hints to some kind of audio buffer issue.

Enabling 'Hear computer audio in VR' and playing certain sounds on PC - triggers the same crackling via Link after a while.

Recording audio that produces noise on PC (by enabling 'Hear VR Audio from Computer') and playing it back via Oculus browser from YouTube I confirmed that the issue is likely not hardware related, but an issue with Link.

Installing the latest chipset, integrated audio (Realtek) and LAN drivers from MSI support page.ĭouble-checking that 'Oculus Virtual Audio Devices' is set as default Playback and Recording device.

Using DDU to completely uninstall Video AND Audio drivers, then Installing the latest NVidia display drivers.

Updating BIOS on my motherboard to the latest version.įorcing my MSI X570 motherboard to use PCI-E 3.0 for chipset and PCI slot. Setting various bitrate settings in Oculus Debug Tool, as well as reverting to defaults (by setting everything to 0/Auto).

Switching from my third-party USB 3.0 cable to provided charging Type-C(x2) cable.Ĭompletely uninstalling Oculus software (removing Oculus folders in /Users/**) and reinstalling it. I'm using Oculus v34 on Quest 2 and tried both v34/v35 PTC on PC. Or playing any standalone game for that matter. No distortions when playing the exact same sounds via YouTube inside Oculus Browser (outside of Link). It feels like there's some kind of audio buffer getting overflowed or something. Can be reproduces with other sounds as well, like voice from the free Berlin Blitz app on Steam (even when watching gameplay on YouTube). Playing Test sound on 'Oculus Virtual Audio Device' via Sound panel also triggers this crackling noise after a few attempts. Crackling noises are heard at certain sound frequencies when streaming via Link/AirLink.
