Unusual noise with stuttering effect
Unusual noise with stuttering effect
Hi, your issue seems related to the onboard sound card rather than a complete failure. There are brief, irregular stutters during YouTube playback that only occur when streaming music or videos, lasting around half a second each. The timing is unpredictable—sometimes three times per minute, other times just once an hour—and it’s exclusive to YouTube. Other platforms like Twitch, Spotify, or games work perfectly. Your system setup includes a Gigabyte B85M-D3H motherboard, an i5 4570 processor, Be Quiet 400W power supply, Crucial 16GB SSD, and Windows 10 64-bit. You've already updated the sound drivers and tested across different browsers and even during Hiren's boot. If this behavior persists across all apps and browsers, it suggests a possible hardware issue with the sound card. Consider checking for any recent changes, such as new drivers or firmware updates, and if problems continue, replacing the sound card might be the best solution.
I wasn't familiar with LatencyMon. I tried it for half an hour. This round didn't have any single glitches, but there were definitely some issues... Log below: Spoiler _________________________________________________________________________________________________________ CONCLUSION Your system seems to struggle with real-time audio and other tasks. You might notice buffer underruns like drops, clicks, or pops. It looks like certain DPC routines from a running driver are taking too long. One potential cause could be power management settings—turn off CPU throttling in Control Panel and BIOS. Also, check for BIOS updates. LatencyMon has been monitoring your system for 30 minutes (0:30:02) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION Computer name: DESKTOP-P0HDT2D OS version: Windows 10, 10.0, version 2009, build: 19044 (x64) Hardware: B85M-D3H-A, Gigabyte Technology Co., Ltd.

This includes scheduling, running a DPC routine, signaling an event, and waking a thread from idle. Highest latency to process (µs): 15,279.50 Average latency (µs): 6,492,128 Highest to DPC latency (µs): 15,274.50 Average to DPC latency (µs): 2,394,802 _________________________________________________________________________________________________________ REPORTED ISRs Interrupt service routines run when hardware events occur.

After testing various solutions, I identified the main cause of the latency spikes as my USB 3.0 WiFi card. Since the 2.0 version worked perfectly, I realized I was lacking the necessary drivers. After downloading them, the issue disappeared. It seems the USB 3.0 dongle was the culprit due to missing drivers.
