Context

While playing YouTube videos in Firefox, intermittent crackling appears after a few minutes of playback. This report documents detailed testing that demonstrates the issue is not related to the DAC, USB interface, or system hardware, and is exclusive to Firefox.

2. System Configuration

CPU: AMD Ryzen 5 5600X @ 43 °C

RAM: 64 GB DDR4 dual-channel (16-20-20-38 @ 1572 MHz)

Motherboard: ASRock X570 Phantom Gaming 4 (AM4) @ 54 °C

GPU: NVIDIA GeForce RTX 3050 (audio drivers disabled, audio hardware off)

Monitors: LG HDR WFHD 2560x1080@60Hz and IPS236 1920x1080@60Hz

Storage: Multiple SSD and HDD SATA drives (500 GB – 2 TB)

Audio: Realtek High Definition Audio disabled; iFi nano/UNO DAC connected via USB with power filtering, using Exclusive Mode / ASIO

3. Tests Performed 3.1 DAC and USB Validation

Continuous playback of PCM 384 kHz/24‑bit and DSD256 via Roon/ASIO.

Duration: over 25 minutes of uninterrupted DSD256 playback.

Result: no crackling, pops, or errors.

Conclusion: DAC, firmware, USB cables, ports, and power supply are fully operational; heavy data load does not cause errors.

3.2 Browser Comparison

Chrome (YouTube, identical conditions): continuous playback without crackling.

Firefox (YouTube, identical conditions): crackling progressively appears minutes into playback, temporarily disappearing when the video is paused.

3.3 Isolation of Variables

USB motherboard ports and original drivers fully tested.

GPU audio drivers and hardware disabled.

Windows Shared Mode off, Exclusive Mode enabled.

Predefined audio formats set according to DAC preferences.

USB power management disabled.

DAC temperature stable; no overheating observed.

4. Technical Conclusion

Hardware: DAC, USB, cables, power, firmware, and GPU are not the cause of the crackling.

Operating System: Windows 11 is correctly configured; Exclusive Mode / ASIO works without errors.

Browser: Firefox is the only element consistently reproducing the issue.

Most Likely Cause: Firefox’s buffer management and audio sandboxing interacting with Windows, causing intermittent interruptions in audio flow.

Summary: All hardware and OS factors have been tested and validated: DAC, USB, cables, power supply, firmware, GPU, and temperature do not produce crackling. The only consistent factor is Firefox, making this a software-bound issue.

Engineering Note: This diagnosis conclusively demonstrates that the intermittent audio crackling on YouTube is caused exclusively by Firefox on Windows 11, independent of DAC or USB hardware. The issue should be investigated at the browser level, specifically how Firefox handles continuous digital audio streams and buffers on Windows.

mozilla keeps crashing almost on every website (says the tab has crashed). I checked, mozila is up to date, all extensions removed, no viruses or spyware, and it is crashing in troubleshoot mode as well.

Also few times a day says "your device ran in to a problem and needs to restart). Please advise what to do? Here is a submitted crash reports:

With the latest update, some of the shortcuts that appear when I click on the address bar have changed. Now several of them are for websites that I don't use on a regular basis. Is there any way to remove them? Is there any way to add back shortcuts for sites that I do use on a regular basis?

Version 146.01 has me discombobulated. no shortcuts to add on anymore. can I have the previous version with my shortcuts?

I was trying to sign in to siriusxm.com. A box came up that said "Please insert your security key", with a diagram that looks like a flash drive. It said the request came from FireFox Mozilla Corp.

Is this one flashdrive key that will work for everything Firefox Mozilla Corp wants to guard, or it is something required by SiriusXM? I've never heard of it, but have seen it pop up for two or three things in the last week. I don't know how to satisfy the requirement. I looked though the topics on FireFox help page, and nothing mentions it that I can find.

Hello, When accessing a site, the page is fully fogged and in the upper left corner is a "Close" which clears the screen. Not sure why this is happening or how to stop it.

Thank you.

Good afternon,

I am writing to request assistance in disabling the Picture-in-Picture (PiP) feature on my browser. Despite my best efforts over the past few days to disable this option through the settings, it continues to activate when I listen to music on YouTube.

Each time I navigate away from the YouTube tab, the Picture-in-Picture window appears and persists across all my other tabs, which is quite distracting and impedes my ability to work.

Closing the PiP window pauses the music, which is not ideal for my experience.

I am looking for guidance on how to effectively deactivate this feature, as the settings adjustments I have made do not seem to take effect.

Any help you can provide to resolve this issue would be greatly appreciated.

Thank you for your attention to this matter.
