Crackling/Clicking/Popping/ Audio Issue

The Issue:
Audio crackles, pops, and clicks on occassion, usually when sound begins or stops.

Examples:

• When I receive a message on STEAM, there is a "bloop" sound that is there to notify me that someone sent me a message. At the very end of the bloop there is a noticeable "click" sound.
• When playing some games where there is audio that loops, at the end of each loop in the cycle there is a clicking noise. Also happens when I skip the intro video that plays at the beginning of the game.
• When pausing and unpausing YouTube videos, the audio of the video is accompanied by clicking noises. If I exit YouTube in the middle of the video, a few seconds after closing out a noise can be heard, which resembles a split second segment of audio from the video. Also, when adjusting the audio of a video with YouTube's volume slider, the audio crackles.
• When using Crtl+f to search for words and it doesn't come up, a ding is played, followed by the clicking noise. This is most notable when I force the dings to occur in rapid succession, by typing random letters. It occurs less often if it is only a single ding.
• When changing the surround sound from DTS to Dolby, there is a "pop" noise.

Specifications:

Logitech G633 Headphones, but the issue was also present on my Logitech G35s. Both are USB devices.

I'm new to this website so I don't exactly know what other specifications would come in handy... if there are tell me how to find them and I will post them.

Thank you so much for replies, I've been looking for a solution for a month now on the web to no avail!

USB devices do not use the PC's sound card, they take digital and convert it to analog audio. Does sound do the same thing with regular PC audio?

Popping/crackling, etc is an often posted problem. Unfortunately there is no "one fix" for the problem. Some known potential items are Wi-Fi, sound drivers, video drivers, power supply noise, etc. With USB headphones drivers for the headphones could be an issue.

I don't quite understand. The only way to play the audio is through my headphones, so I don't know how to determine what the "regular PC audio" would sound like.

"Regular PC audio" is the audio that comes from your speakers with the headphones unplugged.

If you don't have speakers for your PC, then you won't hear it at all. Unless it's a laptop, then you'll hear audio through the laptop's speakers.

Can you borrow some from a friend, just to test it out?

If not speakers, a regular analog headset will also do. Even ear buds with the correct TRS plug.
