High DPC Latency with and audio interface (pops and cracks on my audio)

[KikoH]

Hi,i recently bought a hp pavilion gaming 15 (I710750H, 16gb RAM)  i need some help on my issue on high dpc latency when using a audio interface for recording audio. My interface is a focusrite 18i20 and i bought this laptop for recording and gaming as well and hopefully for live performance once theres live shows again. 

At 144ms buffer size, its manageable but at 144ms, there’s a lot of latency when recording. when I go down to 32 or 64ms so i can record my audio almost real time, there’s a lot of pops and cracks in my audio even when watching videos on YouTube.

When i remove my audio interface and run the default audio through computer speakers, everything is back to normal, there’s no pops and cracks on audio while gaming or watching Youtube videos. 

I find this weird because on my old toshiba laptop(i5, 8 gb ram) , i can run it to 64ms without any issues and on my old asus desktop (i7, 16gb ram) i can run it up to 32ms. I’m a little disappointed with my new hp laptop because its new but has issue on dpc latency and my audio interface worked swiftly on my old lptop and desktop

I tried troubleshooting it with the advice of focusrite support (installing the latest drivers both for the laptop and audio interface, turning off network adapters, other sound  drivers, other devices, configuring usb ports, etc) but still the problem persists. I also updated the hp drivers but theres still pops and cracks.

I ran the LatencyMon program and the laptop seems to have a high dpc latency and it advised me to disable the cpu throttling. I can’t find it in the bios though. How should i fix this or is there anyone in this forum who also encountered this problem when using audio interface, has a solution for it?  

Also, where can I find the cpu throttling menu and is it safe to turn it off? Or should i turn it off when recording then turn it on while playing games? 

Thank you all!

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Does these noises appear on a headphone as well?

While you respond to that, let's try these steps: 

• Updating your Notebook computer BIOS 

• Keeping notebook air vents clear and clean 

• Increasing the efficiency of the notebook to reduce heat 

• Using Windows Task Manager to identify corrupt processes 

• Selecting power saves settings to shut off your computer when it is not in use

(Though the header is different or the link is for another device, the steps to follow will help resolve your concern & By the end of this article all the issues should be resolved)

If the issue persists, please backup all personal data and perform a system reset after creating a new user account to check if that helps.
 

Hope this helps! Keep me posted for further assistance.

Hi

Yes whenever its plug with my audio interface, it has pops and cracks, there’s pops and cracks on my headphones when its plug in my interface’s headphone out. My battery settings also at best performance. 

I already done some on the instructions below and its a generic tip, i need a focus solution please?  My issue is pops and cracks/high DPC latency in my audio when plugged to an audio interface. 

Please if you’re a support agent of HP, kindly give me a more direct solution, i think i applied all the basic troubleshooting and some of the solutions like air vents and increasing efficiency on overheating are unrelated on the issue. I need a more focused solution. (Check the photo attached to this thread, the LatencyMon ones) That would help a lot. 

I don’t think i need a system reset because i just bought it a couple of months ago and i don’t have anything on my laptop except for games and a few music production programs on my laptop. 

Thanks!

Thank you for posting back. 

I have a few troubleshooting steps we could try to fix the issue:  

• 1. Go to Start, search for Device Manager, and open this result.
• 2. Expand batteries.
• 3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.
• 4. Shut down the computer. 
• 5. Disconnect the charger.
• 6. Remove the battery.
• 7. Hold down the power button for 1 minute.
• 8. Insert the battery only.
• 9. Attempt to turn the battery on.

Hope this helps! Keep me posted for further assistance.

Hi, after following the steps of the troubleshooting that you suggested, the problem still there. There’s pops and cracks on my audio still. Same error stated on LatencyMon program. Disable the cpu throttling, etc. i think its not a battery/power management issue though

What are additional steps do you think that will resolve this issue?

Can you please advise if you get this sorted. I’m am having similar issues with my spectre x360 and nothing is working.

Yes, as advised, i’ll contact HP first, if the admins/moderators leave this thread on until its solved,  i’ll post step by step process how HP support solves this issue because this problem is so frustrating. I never encountered this before on other old laptops and desktops.
