well, long and detailed reply
Yep and one that unfortunately 100% does not correspond with what you were asked to do in my reply #8.
Suggestion, uninstall the present audio drivers, restart and use the notebook with just the Windows 11 drivers, do this without the external screen to begin with to make sure that you have audio and that it is of good quality, if all good, using the same drivers hook up the external screen and use the set up as you normally would and see what happens.
The below offers a good clue;
- It only happens when connected via wireless (not Bluetooth).
Again suggests that it is not driver related, it would happen regardless of what connection you were using otherwise, are you aware that the wireless WAN antenna assembly and the speaker assembly wires and modules run and are assembled next to each other on the base of the notebook.
Hello! Sorry for the long delay -- life got in the way.
Was going through all of the past replies, thought I should just answer some questions again as a refresher of where this is at:
Model: X1 Yoga 7th Gen (Type 21CD, 21CE) Laptop (ThinkPad) - Type 21CD
Your question: Does the issue happen if you do not have the second screen hooked up.
ans: No, it only happens from my 2nd screen. And, I've come to learn since my last post, only when hooked up via pairing (i.e., through my network, not via HDMI cable, which I can also use to connect the PC to the TV).
Q: From where is the crackling noise coming from, is it the notebooks speakers or the external screen speakers.
ans: Only from the external screen speakers and only when videos play; not when music alone is played. (And it doesn't happen on the screen speakers when, say, watching a streaming channel or DVD or the like).
Suggestion, uninstall the present audio drivers, restart and use the notebook with just the Windows 11 drivers, do this without the external screen to begin with to make sure that you have audio and that it is of good quality, if all good, using the same drivers hook up the external screen and use the set up as you normally would and see what happens.
OK! So I did it exactly as asked this time! And after about 45 mins or so of watching, yes, the crackling returned on the Windows driver! Like before, it's minor at first and gets worse and worse to the point that audio become completely garbled. (Here's a link to an audio file, so you can hear it at its worst -- this is audio from a YouTube video of two guys discussing a movie.It was playing on the TV [via the PC; pairing] and I recorded it w/my phone). So it seems like you called it! (I should never have doubted you!)
So, does that mean we test the video drivers now, or does it mean it's my TV? (Which would be weird b/c I've had this TV for over a year now. WAIT! It's actually a different TV. That is, it's the same make/model, but b/c of an irregularity in the backlighting of the screen, they sent me a replacement at around the same time I updated the drivers. Do you think this TV's hardware could be faulty? Wow. That just freakin' occurred to me.)
Should I reinstall the RealTek audio driver now btw?
Anyway, thank you again. And, once more, sorry for the delay. Please let me know if I should contact Roku or test something else here first. Be well.
