   Realtek audio device not showing up in device manager and windows says "UNKNOWN"

   Beldr posted a question in Drivers and Hardware

   Hey!I have a Lenovo ideapad 330 and it comes with a Realtek audio device built in. I have had the laptop for 3 months now and suddenly my sound stops. Only bluetooth still works. when I click on the sound icon at the bottom right, the help-wizzard audio appears. This one says they have no solution. and when I right click on the icon it says: speaker settings: UNKNOWN. and when I go to the sound settings of windows in the settings menu it says that no input and output devices are available. Also my Realtek audio device is not in the list with device manager. so i can't check the drivers or reinstall them. I thought I would solve the problem by implementing the new windows update (v 1903), but that didn't help. Also restarted several times. just for clarity .. the problem was already there for the update. I've been through the entire internet but can't solve it ... Can you help?Greetings Sem van de BeldNetherlands(sorry for the bad english .. Google translate :))

   Constant High-Pitch, Alert-like Sound Playing From PC Even When Sound Devices Are Muted And Disabled.

   Bill_515 posted a topic in Software and Apps

   Hi, For the past several months, I've been experiencing my PC randomly emitting this high-pitch, alert-like sound from my monitor's speakers even after I mute and disable all sound devices. It would only stop when I shut down my PC. At first, it would only happen once or twice a week. But now it occurs several times a day and I don't know what to do anymore. If anyone is wondering, I made sure that there were not any background programs running in Task Manager during these sporadic episodes. Since this has only started happening as of a few months ago, perhaps this is some sort of glitch caused by a Windows Update? Here is a Google Drive link to a video I took of the computer making these sounds: https://drive.google.com/file/d/1KtW4V-XTwbNWJhlnZZpR_CeE5zvyIjXN/view?usp=sharing OS Specs: Edition: Windows 10 Home Version: 20H2 OS Build: 19042.1348 Experience: Windows Feature Experience Pack 120.2212.3920.0 Is anyone else having this issue? Any insight into this befuddling situation would greatly appreciated.
