Audio stops working after a few minutes

November 27, 2016 at 03:32:55
Specs: Windows 10

I swapped my previous PSU since it had failed. I've been having this issue since then. I boot up the computer, start watching a video, after a few minutes the audio goes off completely and I start hearing that whizzing noise, though it's very quiet.

I've tried reinstalling the audio driver. Didn't help.
Updated GPU driver just in case, didn't help.
Tried other audio devices, didn't help.
I also made sure I was using the correct rear port.
Updated BIOS, still not workin

MSI Z170M Mortar
RX 480 8gb
Antec HCG-620 PSU
Windows 10 64-bit

This looks like a motherboard issue, though I'm not sure what to do about it.

As this happened after swapping the PSU I would be inclined to check the output voltages with a multi-meter.

Was it a brand new PSU and was it rated in wattage and amperage as equal or greater than the original?

Does the audio cut out suddenly, left and right channels at
exactly the same time? Does the "whizzing" sound come
equally from both channels?

Seems odd the PSU would affect the audio. Being that the audio begins to work & then cuts out after a few minutes, I would suspect a software issue. If you close the video, then restart it, does the audio work again? If not, what does it take to get the audio to work again - reboot? What software are you using for video playback? Have you tried audio CDs or MP3s? If you're not already using it, try VLC Player.

"Tried other audio devices, didn't help"

What does that mean?

Thank you all for your time. Appreciated the effort!


"check the output voltages with a multi-meter." How do I actually do that? Is there a some sort of guidance out there?

Previous PSU was brand new. Although it was a poor brand with poor overall quality, hence the failure.

"Was it a brand new PSU and was it rated in wattage and amperage as equal or greater than the original?"

What are you referring to "original" ?

@Jeff Root

Well, it varies. Sometimes it cuts out suddenly without showing any sign, sometimes sound keeps working but starts that LOUD whizzing, buzzing noise and after a very short while it goes off completely.

No, whizzing sound is not equal on both sides. In fact whizzing sound is not eve consistent. Sometimes its volume increases then decreases. Sometimes its way of whizzing alters to some other whizzing sound.


It's not about videos. The whole onboard audio stops working, not just specific types of applications.

Yes a reboot fixes it for a short while. Then it goes off again.

It means I tried using other headphones, speakers. Result was the same.

Here's a link about testing PSU:
However it might be a tall order if you are not familiar with a multimeter.

I was asking about the current PSU because I wondered if the replacement was adequate.

What happened to the previous PSU? Blown up (smoke?) or just stopped working. The Audio circuitry, and maybe other circuitry, may have been hit with a voltage spike when the old PSU malfunctioned.

Oh yeah, the new PSU is more than adequate. Higher wattage and amperage.

That guide is quite bothering. Though, I'll keep it in mind. Maybe in the future I'll go through it but unfortunately it's not doable for me currently.

Do you really think that kind of deep PSU check-up would somewhat help me resolve this issue?


It failed during a consistent high load situation. Screen went black and I had to force restart it. Since then computer started freezing when I load GPU in any way. Screen'd go black then I'd force restart it. This restarting process happened maybe 30-40 times during the time when I was trying to figure out what was going on. It was then I opened the case and saw the melted,deformed pins of PCI-E power cable. I dumped it and bought the Antec one.

I don't regard it is that deep but it would go a long way to eliminating the PSU from the equation. It is under suspicion because you said this problem came along after it was installed.

So then, you are using the CPU based integrated graphics and the Motherboard based sound chip. Did you install the required drivers from the included CD that came with the motherboard?

I appreciate the fact that you are trying to help. But did you even read the original post? I'm not using an integrated GPU. When I say "audio", I refer to the onboard audio(motherboard chip).

I also clearly pointed out that I had installed the required audio driver.

Onboard audio IS an integrated GPU (chip). The alternative is an add-on (separate) card. Best not get shirty with helpers especially when they are right.

My bad, I missed the install graphics card. The 6600k has integrated graphics and that is what I referred to.

Many folks let Windows or a third party install drivers. This isn't the best practice IMO. I assumed you were using integrated sound because that is the majority of all computers. All that said, the key here is the source of the drivers.

If you go to Device Manager you can determine the actual drivers in use. You may also be surprised to see they are not what you expected.

I am skeptical of the PSU being your problem. You would most likely develop other issues before sound cutting out if that were the cause.

A GPU is a graphics processing unit. It doesn't do audio.

PSU check is a cheap and easy to do with a $3 checking tool , I recommend it to all serious PC owners regardless of the issue

It does sound like a hardware issue , almost like something loosing its charge

The easy work around would be to buy a usb sound card

The best bet would be to return the Mobo to MSI under their 3 year mobo warranty

Other thing you could try is thoroughly discharge the system , remove the power cord and hold the power button for 30 seconds , or leave overnight to discharge

Also check to see if on board audio is enabled in bios , try disabling it booting up then shutting down and then re-enabling it

"PSU checking tools" are fairly useless, especially the ones that simply report back using colored led codes. A multimeter is better. You can get a cheapie at Harbor Freight for next to nothing with a coupon. It doesn't help when it comes to amperage output though; special testing equipment is required for that.

Have you tried temporarily removing the graphics card & using the onboard graphics to see if that affects the audio? If you can't get the sound problem sorted out, I suppose you can always disable it in the BIOS & then install a PCIe x1 soundcard. Speaking of BIOS, did you reset it after the update & then manually configure the settings?

One last thought - system restore to a time before the problem?

Is the power from the wall outlet 50 Hz or 60 Hz ?

Does the PSU have a switch for selecting 50/60 Hz ??

If so, is it set correctly???

If not, is the PSU designed for what you have????


I looked up your Antec HCG-620 power supply.
It appears to handle 50 or 60 Hz without user intervention,
so that must not be the problem. I was thinking that the
noise might be hum from the line current.

In the UK I've never run into a 50/60 Hz switch - maybe a USA thing or something I've missed. In the UK even a voltage setting is now rare - modern PSUs being capable of a wide voltage range.

One thing I forgot to mention. I formatted the whole hard drive a few days ago. A fresh install of windows 10, audio mobo gpu drivers etc. I used MSI live update 6 to install the audio driver. When I go to device manager to check the driver, it is displayed as Realtek HD Audio, just as it should. So nothing surprising me there.

Just to clarify things, the problematic audio is the onboard one that is integrated with the motherboard and nothing else.


You are wrong, sir. A GPU does produce sound, at least mine does through hdmi. But this is irrelevant with the topic.


Currently, I'm using a usb sound card. But this doesn't mean I'm accepting a broken motherboard.

I sent a support ticket to MSI regarding this issue. Their first instruction was to clear CMOS. I haven't tried it yet, will do it ASAP. I also tried deactivating-reactivating the HD audio in the BIOS settings, didn't help.


No, I haven't tried removing the graphics hard. I may give it a shot, even though it sounds kinda irrelevant to me :P. Maybe I'll also swap it with my old 750ti.

No, I haven't done anything related to resetting the BIOS. Do you refer to clearing the CMOS when you say reset BIOS?

System restore? Impossible, literally :(


Outlet is 60Hz. FYI I reside in Turkey.

Your 660l processor has integrated graphics but no sound capability. HDMI cables simply combine graphics and sound for a neater all in one solution. See the spec sheet link below.

If you performed a clean re-install of Windows 10 then my question would be this? Did you have the add in sound card installed at that time? If so, you may not have installed the exact drivers written for your integrated sound chip.

Realtek supplies reference drivers to manufacturers and on their site. Manufacturers in turn tweak their drivers to provide whatever features they wish to include.

If you doubt this, then go to the Realtek site and see what they have to say about the subject.

So the possible issues could be one of the following. Wrong drivers, incorrect sound settings, or defective motherboard.

Realtek HD software requires that you actually click on the port setting, even if it already appears to be set correctly. I am not sure if special settings are required when using HDMI settings, as I have not tried what on a computer. Try headphone settings with the on board sound to verify functioning.

Did you try uninstalling the drivers from "Device Manager" then restarting the system? Also, did you try updating the drivers from Device Manager?

I never mentioned my CPU had sound capability. The GPU has it though. If I connect the GPU to my TV via HDMI, I do get the GPU to produce sound and output it through the TV's integrated speakers. But it's not Realtek Audio, it's AMD True Audio. Sound from HDMI has nothing to do with Realtek HD Audio.

No I didn't have the sound card at that time. I bought it afterwards.

I highly doubt the wrong/broken/corrupt driver possibility. Unless MSI provides the wrong driver at their website, it can't be the issue.

"If you doubt this, then go to the Realtek site and see what they have to say about the subject. " Do you mean I should try downloading the driver directly from Realtek's website?

I always make sure port is set to headphones.


Once the driver is uninstalled, onboard audio will no longer work obviously. Not sure what you were thinking there :P

Yes I did try updating. Windows said it's up-to-date.

I believe the motherboard is somewhat defective. This would require an RMA which means at least 2 weeks without a computer.

I'm just sad...

No the above is NOT the case provided you do it from Device Manager. All it does is unlink the driver software. When you restart the system it will "find new hardware" (audio) and set up the driver again. Sometimes setting it up again can fix issues which is why I suggested it.

Note these:
1. If you are asked whether to "remove the software" then do NOT allow it to do so, otherwise you can ignore the warning.

2. if any errors are showing in Device Manager audio then let us know instead.

See this (third response) if you are still in doubt:
It applies equally well to audio.

The GPU is not producing sound. You are getting sound from another source, not the GPU. That is why I linked the specs for your CPU. Intel specs do NOT include any sound capability.

Below is a link to an HDMI standard, which explains that HDMI cables are capable of carrying multiple types of signals.

The second link below is for the specs on the intel Z170 chipset, which is used on your Motherboard. Note the Audio listing in advance features.

So, you have 2 audio sources. Settings could still be an issue. Windows has some sound settings that include exclusive use of sound devices. Expand the Sound listing in Device Manager. You should see 2 listings there. They use different drivers. The intel portion driver should be part of the Z170 chipset package.

I just performed the remove Audio Driver process(did not uninstall it which windows prompted an option for it) Restarted the PC. Well, I did not get a prompt saying "a new hardware detected", instead, initially I had no sound from onboard -it was as if the driver was uninstalled, a moment later it was all set up. It kept working for 15-20 minutes then went off again. During that time though, I realized the sound quality was noticibly worse than before.


When I extend the audio devices list I see 2 things: Realtek HD Audio and AMD High Definition Audio Device. Realtek is the onboard audio, obviously. What about the AMD one? If my GPU doesn't produce any sound then why do I see AMD's title there?

And I'm also unsure why you brought up the CPU/Chipset specs.

"Intel specs do NOT include any sound capability."
"The second link below is for the specs on the intel Z170 chipset.......Note the Audio listing in advance features."

Am I missing something here? Does the Z170 chipset produce the sound and not the 6600K?

The Z170 chipset has integrated sound. However, that doesn't mean the board maker is using it. Each feature they use comes with a cost, so they may or may not. Even so, both the Realtek sound chip and your RX480 have the capability of passing thru sound from other sources.

See the excerpts and links below for more incite. Especially the quote from AMD on your RX480 engine. From that quote I would venture a guess at the cause of your sound stopping. Your RX480 may be overheating.

Below from the Realtek site:
"The ALC892 supports host audio from the Intel chipsets, and also from any other HDA compatible audio controller. With various software utilities like environment sound emulation, multiple-band and independent software equalizer, dynamic range compressor and expander, optional Dolby PCEE program, SRS TruSurround HD, SRS Premium Sound, Fortemedia SAM, Creative Host Audio, Synopsys Sonic Focus, DTS Surround Sensation | UltraPC, and DTS Connect licenses, the ALC892 offers the highest sound quality, providing an excellent entertainment package and game experience for PC users."

From an AMD site on the R480 architecture:
Polaris architecture precisely combines the latest FinFET 14 process technology and AMD’s advanced power, gating and clocking technologies to deliver a superior cool and quiet gaming experience. "Enjoy gaming features that dynamically optimize sound volumes based on actual temperature and workloads".

If the sound quality is changing then overheating is a possible cause - as per #26 2nd para.

That's a huge claim. The RX 480 hovers around ~54 degrees celcius when I'm surfing on the internet. This includes youtube videos. So, if watching youtube videos at 54C is considered as "overheating" and causes my sound to stop working, I'd say there is something horribly wrong with my hardware....

Let's say this "overheating" somehow causes the sound to stop working, this means there is still something wrong with the hardware. Obviously, GPU overheat is not supposed to cause such a problem.

"The Z170 chipset has integrated sound. However, that doesn't mean the board maker is using it." If the board makes isn't using that integrated sound, then how is the onboard sound produced?

What is the source of the onboard audio? I'm kinda confused, did some googling about this but nothing really answered my question.
