I inherited a 4K TV and have been using Verizon FIOS fiber optic internet with Gigabit internet speed since we moved to Virginia! I've been using a laptop because it was the smallest computer with a dedicated video card I had. Everything worked smoothly with 4K streaming and audio. Finally I was able to build a dedicated compact computer just this week to replace the laptop. I love this build because its extremely small, compact and still allows a dedicated video card for some gaming and 4K streaming. Unfortunately I am experiencing some strange audio issues. Symptoms: Audio drops when interacting with windows and buttons Repetitive random scratching static sounds in all speakers Some system sounds half-trigger - like during speaker tests Chrome movies & music randomly lose audio (muted for a second) Keyboard buttons randomly will not increase/decrease volume Other than these symptoms, everything is running and installing perfectly Steps Taken Linux: Updated Nvidia to 525 Downgraded to Nvidia 515 Downgraded to Nvidia 510 Tested in Nouveau open source (testing again) Changed to HDMI 2-ch Stereo Changed to HDMI 5.1 Changed to HDMI 7.1 Increased Cinnamon memory limit to 8000MB Disabled Compositor Disabled windows effects Created test profile in Mint Installed Mint 21 Adjusted refresh rates: 50, 60, 30, 25, 29.9 Changed screen resolution to: 1920x1080 Bought new 4K HDMI Cables Tested DisplayPort to HDMI Separated video and audio with two cables Software: Tested in Chrome (Netflix, Prime, Youtube Tested MP3 with Rythmbox over network Tested MP3 with Rythmbox directly from the desktop Tested in Firefox Hardware Swapped HDMI cable Swapped Video cards Tested with analog stereo RCA cables (humming/stuttering artifacts when interacting with windows) MemTest - Currently running Specs: LG 4K Smart TV Sony 5.1 surround AMP (brand new) Linux Mint 21.1 Cinnamon Nvidia 525 GIGABYTE GeForce GTX 1650 4GB GDDR6 PCI Express 3.0 x16 mini-ITX Video Card GV-N1656OC-4GD https://www.newegg.com/gigabyte-geforce-gtx-1650-gv-n1656oc-4gd/p/N82E16814932287 Enermax Revolution SFX 650W Full Modular ERV650SWT https://www.newegg.com/enermax-erv650swt-650w/p/1HU-00R5-00007?Item=1HU-00R5-00007 Intel Celeron G6900 - Celeron Alder Lake Dual-Core 3.4 GHz BX80715G6900 https://www.newegg.com/intel-celeron-g6900/p/N82E16819118378?Item=9SIA1K6H6N9925 SAMSUNG 870 QVO Series 2.5" 1TB SSD https://www.newegg.com/samsung-1tb-870-qvo-series/p/N82E16820147781?Item=9SIBFJRJ949674 CORSAIR Vengeance LPX 16GB RAM DDR4 3200 (PC4 25600) https://www.newegg.com/corsair-16gb-288-pin-ddr4-sdram/p/N82E16820233867?Item=N82E16820233867 CMK16GX4M2B3200C16R ASRock DESKMEET B660 Intel 12th Gen Mini PC Barebone System https://www.newegg.com/asrock-deskmeet-b660w-b-bb-box-us/p/N82E16856158084?Item=N82E16856158084
This is certainly not an easy one to figure out. Have you tried to play sound over other outputs than HDMI? Just to attempt to narrow down the issue, see if sound plays fine on any other output, audio jack, or some USB sound output if you can test it. Otherwise, the only thing that comes to mind at the moment might be bad RAM. Trying out some other RAM sticks might be worth a test.
Yes, I have used the speaker jack on the motherboard and ran it to RCA on the amp. It seemed to work fine, but I didn't try analog for a long period of time. When I disabled Compositor yesterday it got better, but it seems to get worse over time. Oh I forgot to mention I am using a Sony 5.1 surround AMP (brand new) and an LG 4K Smart TV. I'll add these to my list of specs. I previously had a tiny Shuttle PC and later a Lenovo laptop connected to it and never had audio issues. So I'm almost sure its something with my new build and maybe Pulseaudio I tried installing Pipeline and uninstalling Pulseaudio, but Cinnamon will not run without pulseaudio. Won't even boot to the login screen. I thought about the RAM too, I'll test it with a flash drive using MemTest and see what happens. Its super rare, but has happened before.
I want you to try one thing, just to rule out other issues. Create a brand new user profile on this computer, and try it out with the new user.
I tested with analog connection (speaker jack to RCA) for an hour watching a movie. No audio dropouts or statics sounds the whole time. There was some faint stuttering, but I think it was just interference. I"ll try the test profile now. By the way, I also tried deleting /home/booman/.config/pulse directory and killing pulseaudio, which seems to work for a bit, then it starts up again slowly. Also, I noticed when I click objects like windows, buttons or opening windows and clicking makes a sound artifact. Very strange but maybe its something to do with X server or interacting with the operating systems
Ok, I was able to create a new profile and the sound artifacts & dropouts still occurred. This morning I started a MemTest scan and will let it run for about 4-6 hours. So far no errors. I'm going to test the Neavou drivers again because I can't remember if it had the artifacts as well. I'm hoping it isn't the video card, because I would hate to send it back. I really don't think it is because I swapped the 1650 with my old GTX 950 and it had the same problem Thank you for your help!
I don't know for sure, but if the PSU can't power the GPU properly then you might experience stability issues, which I suppose could manifest in the way you experience. But there are some troubleshooting steps you might want to try from the Arch wiki: https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling https://wiki.archlinux.org/title/PulseAudio/Troubleshooting#Disabling_timer-based_scheduling Those seems like the first things to try out, but there are other points there as well.
I thought about that as well. The Enermax PSU is a tiny power supply but 650watts. The video card does not have external power requirements, but maybe it is still struggling. i would think there would be more screen related artifacts, specially when playing movies in 4K on the TV. But when I tried the GTX 950 it does require a 6 pin power connector and still didn't have any issues with 4K. Just the audio artifacts. I ran the Memtest and it came back successful I was also wondering about the Ubuntu Driver Manager. I'm noticing some differences from previous versions of Mint. Notice there are two different Nvidia drivers? Nvidia driver (open kernel) metapackage Nvidia driver metapackage I wonder what "Open Kernel" is? I'll take a look at those pulseaudio solutions. Thanks again!!! You are always a lot of help when I need it!
Nvidia has started to release open source driver (nouveau is also open source, but not developed by Nvidia), but as far as I know it only supports a few GPU's at the moment. You could always try the open source driver, I assume it supports your hardware since it is recommended. The proprietary driver is an external kernel module, while the open source driver is in the kernel.
I'm all about stability so I would rather use the closed source as I always have. I'll try that too! By the way, been testing with the Nouveau driver and there is a tiny bit of static clicking but no audio dropouts at all for several hours of music. Not sure if that means anything??? But I seriously can't use it because it won't do 4K fullscreen or gaming. I also tried the pulseaudio tsched=0 but no effect. I might try the other pulseaudio suggestions as well.
The Nvidia open driver is undoubtedly as stable as the proprietary driver, it is developed by Nvidia after all. As far as I understand, the plan is to fully open source their Linux driver so I would not worry about trying it out.
Ok, well I have tried the following drivers and still having the artifacts: Nvidia 510 Nvidia 515 Nvidia 525 In the archlinux wiki there are a few things I don't understand... How do I know if my CPU is an Intel using IOMMU? There is a not about real-time kernel which I've read about for recording multi-track audio, but I don't think I need that in this case.

By the way I added links for all the hardware I purchased in the original post. The GeForce GTX 1650 is here: https://www.newegg.com/gigabyte-geforce-gtx-1650-gv-n1656oc-4gd/p/N82E16814932287 It supports 8K resolution and requires a 300W PSU The Enermax SFX I got is 650W so it should be enough. But it IS really tiny. I'm testing right now with the screen resolution at 1920x1080 and so far its working fine with the audio. So I'm gonna research the GTX 1650 and 4K TVs I have a spare Enermax power supply I might be able to test but I'm not sure if it will fit in the case or properly grounded.
I'm looking at my ThinkPad laptop right now. I installed Mint 21 on it and used a USB-C Thunderbolt to HDMI cable and it ran 4K just fine and no issues with audio. It has a GeForce Quadro T1000
Update - Looks like 1920x1080 runs fine in Mint 21 for now. Been using it all day and no audio artifacts at all... Really sucks because when I want to watch a 4K video on Amazon Prime I can't... not the end of the world, but really sucks because my Verizon Fios internet is super fast gigabit. Any thoughts? Could it be the GTX 1650 isn't getting enough power?
Hey, sorry for late reply, been occupied. It does sound like a power issue, which is odd as it shouldn't be a problem according to your specs. It could simply be a bad PSU. But, did you try both these settings at the same time for PulseAudio: Code: /etc/pulse/default.pa load-module module-udev-detect tsched=0 And: Code: /etc/pulse/daemon.conf default-fragments = 3 default-fragment-size-msec = 5 Then make sure PA is restarted.
No problem! I'm in no hurry anyways. Nope, I didn't try the tsched and fragment size at the same time. I'll give it a go. I was also thinking, maybe my HDMI cable is cheap and inferior. I have noticed a lot of lip-sync in videos on Youtube and Prime are barely out-of-sync. Here is an idea I had: Run a DisplayPort to HDMI from video card to TV Run an HDMI cord to amp for surround sound This way, the load isn't on a single cable and maybe everything will sync properly and eliminate the noise. I can probably return the power supply if I need to, but everything else seems to be working fine. Even the video looks beautiful!
Ok, I got the DisplayPort and HDMI cables and gave them a try. I did a few things and still got audio drop-outs, but the video is beautiful! DP/HDMI to TV and HDMI to AMP DP/HDMI to AMP and HDMI to TV DP/HDMI to AMP then HDMI out of AMP to TV All three still produces audio crackling/static and drop-outs. Its so strange because the crackle/static is only happening when I click on other windows or OS objects and its not very disruptive... but the dropouts start to happen later on when I tested other videos and it gets worse and worse. I also watched the System Monitor during the tests. It was a bit high for CPU but never peaked at 100% for both cores Memory and Networking look fine. So now I'm thinking: Buy a less powerful GPU like a Quadro? Buy a more powerful SPX PSU? But the GTX 1650 I'm currently using doesn't require extra power. All of the power is from the PCI-e slot on the motherboard. So how do we know its not receiving enough power? I only have three things using the power supply: Motherboard CPU SSD So if these in combination with the video card are using too much of the 650watt PSU, then a more powerful PSU should be the solution... I think I'm performing one last test by eliminating the AMP all together and going HDMI directly to the TV. So far so good... just doesn't sound great... Just watched the rest of Lord Of The Ring: The Two Towers on Netflix with HDMI directly from the video card to the TV... No AMP. Audio was fine. No drop outs or audio artifacts. So this is telling me there is something happening in the AMP. I'm going to double-check the AMP video specs and then contact support about it.
Hey Daerandin, I was doing some more testing... I noticed my CPU usage is a bit high while streaming 4K video. It isn't maxing out, but holding steady at 80%, no higher than 83%. Do you think this would cause any audio dropouts or video frame stutter? Hold on, I just found an Intel Core i3 Quad-Core CPU for $82 on Newegg.com https://www.newegg.com/intel-core-i3-12100f-core-i3-12th-gen/p/N82E16819118357 I went ahead and purchased it. This CPU doesn't have a bundled GPU which will make things less complicated as I have an onboard GPU, Video Card and Intel CPU/GPU. Who knows which one is processing the video codecs?
