I'm considering buying a USB audio interface, so if that even works, that could be a solution. Check that your AC power plug is connected to the ground. Possibly plug the computer in another plug, in another room, and see if this makes any difference. FWIW, I managed to reduce similar noises by putting ferrite rings on most cables, the HDMI cable was a significant source of noise in my case. I didn't try to put ferrite rings on the internal cables (ex. those between the power supply and the motherboard), but it might make sense as well. Certain motherboards are just not well designed and noise might remain, no matter what you do. A good audio interface would solve this problem, assuming you're using speakers that don't generate noise or passive headphones. HTH I'm definitely going to try different outlets later on, along with a few other tests dealing with the power delivery. Fortunately the noise is light so I can wait until a better time to disconnect and move things around. In your case, were the noises loud and audible through speakers? Also, how did you determine which cables needed ferrite rings?

You now have more information towards a resolution. That's a good thing, but not enough. "My toaster shocks me every time I touch the metal case. I resolved it by not touching the metal part of the toaster." However, once I got rid of that static, I noticed some additional noise that was apparently hidden behind the original static.

It is very reasonable that they could now have bad wires or other problems. Do you still hear these noises with other earphones or speakers? Yes, when I first noticed the noise, I tested the earphones with a MacBook Pro, and there weren't any audible sounds at all (silent as far as my ears could measure). Before installing OpenBSD on this computer, it was running Windows 11 for about 8 months, and I never noticed any noises, but I can't guarantee they weren't there either. I'm going to do some additional testing soon, and one thing I want to try is to load up a Linux live environment with working audio. As far as speakers go, I can't hear the noise through them (it's too faint and not affected by volume level). Does anyone have any ideas? This isn't a big deal since I can't notice it while listening to audio, and it's pretty easy to tune out even without audio, but I'd still like to remove it if possible. I'm considering buying a USB audio interface, so if that even works, that could be a solution. I advise finding out what the problem is before buying anything new. You might find the same problem getting passed through another audio device. I suspect that you will need to fix a hardware problem. Don't assume that audio noise is in software. You are surrounded by 50/60Hz noise caused by the power in your house/office/workshop. I agree. I've been looking at audio interfaces for a while, and wouldn't buy one simply to avoid noise. Electrolytic capacitors can go bad (Even brand new capacitors can be defective). Look up bad motherboard capacitors and you can find some pretty good pictures and information. You can find some good YouTube videos on it too. I would also suspect grounding problems as a possibility. Which can mean bad connections with cables even if they look good. You can be having a power supply problem too. Check for loose motherboard screws. Are you using the computer with the cover off? Do you get these noises with the computer on, but then turning off the monitor and moving the mouse around? Nope, the cover's on. I didn't turn the monitor off, but I did disconnect the display port cable, and the noises were still present. Is your electrical wiring done properly? Do you have any other equipment hooked up that might be causing ground loops? Excellent videos on YouTube about ground loops and audio problems. Do you have any OLD radio or TV equipment that could be latching onto the computer noise and amplifying it? Also, if you can, go unplug (not turn off) things around that could be defective. For example, I have to throw away 3-4 USB chargers every year. Nowadays, hardly anything is actually turned off anymore. I used to hear noises like these too, but that was a long time ago... I could hear them in my memory while reading your email. Thanks for the ideas. I've compiled a list of additional tests I want to perform (some will have to wait though). Good luck, Chris Bennett
Audio issue: noise/interference
I recently resolved an audio issue where I could hear a constant, light static noise in my earphones. It wasn't loud or distracting, but it was always there.

yes, by default the device always does DMA in both directions
(synchronously), so record.bytes increases like play.bytes
Great to know! This, along with the other details you've provided, will
help me understand what I'm seeing much more clearly now.
Thank you.
2) What is the source of this data (record.bytes)?
The source is the audio hardware interrupts. The audio(4) driver
handles them and increments its couter. The counter is readable by
userland with the AUDIO_GETPOS ioctl.
I found it interesting that the values were the same, so I took a look
at mixerctl, and noticed that 'line' (which is an output) and 'mix'
(which has line as its only source) were the sources for both
record.adc variables. At that point I figured that simply removing
all sources from those two variables would eliminate all audio data
from those recording channels, but record.bytes continued to match
play.bytes. I even attempted to mute both ADCs and to disable
recording
in mixerctl (without rebooting), but nothing changed.
I'm probably going to remove 'line' and 'mix' as sources for the ADCs
because they don't make sense there, but I'm still hoping to
understand
what's going on.
The mixer is a completely different thing and is completely
independent from DMA. It is supposed to control the analog
knobs/selectors, jack sensors, and alike.
Setting the record level to 0 (or removing all sources) would make the
ADC sample silence and produce zeros without affecting how it
works. That's why record.bytes still increases.

Firefox and DPMS
When watching fullscreen videos in Firefox on my OpenBSD desktop, Firefox doesn't inhibit DPMS, allowing the display to turn off. This isn't new for me, since I noticed the same thing back in 2018. At that time, I tested Chromium as well, and it performed as expected by keeping my display on. I've looked into this a couple of times since then, and at this point I'm sure it has nothing to do with OpenBSD. Instead, it seems to be due to the way Firefox attempts to inhibit DPMS and/or the screensaver, which apparently doesn't work with a simple window manager setup like mine. I assume it works fine under XFCE and Gnome. I've worked around this issue by creating keybindings to disable and enable DPMS manually when needed (using xset), so this isn't a high-priority problem for me. However, I was hoping to see if others have experienced the same behavior, if anyone can confirm my assumption about WMs/DEs, and if there's a better way to deal with it.
Re: Suspend/resume does not work on Lenovo X1 Carbon 3rd gen laptop
That's great. If hibernating is what you're really after, I hope that gets worked out at some point. I don't currently use OpenBSD on laptops, so I don't know what else can be done. At least suspending works though. ‐‐‐ Original Message ‐‐‐ On Saturday, April 3rd, 2021 at 1:09 PM, Mark Hesselink wrote: > Hi Ricky, > > I tested your suspend suggestion and interestingly suspend works like a > > charm.

Re: Suspend/resume does not work on Lenovo X1 Carbon 3rd gen laptop
Hey Mark, I don't have an X1C so I can't offer any hardware-specific advice, but I see you're using the ZZZ command to hibernate the system, yet it appears you want to suspend the system (based on wording). Have you tested zzz (lowercase) instead? Maybe your hardware/setup doesn't support hibernation. If you are indeed trying to hibernate, then I have nothing. Sorry. ‐‐‐ Original Message ‐‐‐ On Monday, March 22nd, 2021 at 8:20 AM, Mark Hesselink wrote: > Hi, > > I'm sending the below bug report to misc@openbsd.org as I have > > deliberately not configured my OpenBSD workstations to be able to send > > mail -- they are mostly used by my children -- and a bug report sent > > directly to b...@openbsd.org never seems to have arrived.

Re: OpenBSD Monitor Sleep No Response
As previously mentioned, you can use xset(1) to disable DPMS (and the screensaver, if necessary). I use the following commands to disable and re-enable these temporarily. xset s off -dpms xset s on +dpms Since your keyboard also becomes unresponsive, it looks like you're problem is something else, but if that problem is triggered when your display enters power saving mode, this could help until you find a solution.
