fixed: Audio Clicks and Pops with OSD panel enabled AIDA64 v5.30.3500 (Dell SMI + Windows 10 Pro)

Recommended Posts

When "Show OSD panel" is enabled, audio output exhibits clicks and pops intermittently, but appears to be multiple of 5 seconds.

With USB audio (DAC), the frequency is ~ once every 30 seconds. From headphone jack, it ~ once every 1 to 3 minutes.

It occurs when playing music from iTunes or VLC.

A simple way to notice this is to play a test tone, e.g., 1-KHz tone from a test CD. 


So far, it's reproducible on multiple Dell laptops, latitude e6430 (i5-3340M), latitude e6410 (i7-640M) and vostro 1400 (T7250). 


OS - Win 10 Pro (RTM - Build 10240)

iTunes v12.2.2

VLC v2.2.1

Try to disable Dell SMI sensor support in AIDA64 / main menu / File / Preferences / Stability, and restart AIDA64 to apply the changes. That way you will lose a few readings on the Computer / Sensor page though.

I'm not sure if this can be resolved, since the audio issues are caused by the Dell SMI BIOS layer that AIDA64 has to handle to read Dell SMI sensor values. We'll try to come up with an alternative access method, although I'm not sure if there's one exist at all. Do you have a Dell software that can read those sensor values without audio issues?

HWiNFO64 should use the same access method. But AIDA64 does a few tricks when e.g. CPU temperature cannot be measured via Dell SMI -- and that may just make a difference. Also, AIDA64 supports 2 different interfaces to issue Dell SMI calls, so it would be necessary to understand the exact method used on your system. Please create the following outputs and send them in email to me (I'll send you my email address in private message in a minute):

1) A screen shot of the Computer / Sensor page of AIDA64. If possible, please adjust the window size to show all readings on a single shot. If not possible, then please create 2 screen shots to make sure we can see all information.

2) A screen shot that shows HWiNFO64 Dell SMI readings. I think it's called Dell EC in HWiNFO64.

3) Right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> ISA Sensor Dump. Save it to a TXT file and attach it to your email.

4) Right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> Embedded Controller Dump. Save it to a TXT file and attach it to your email.

Thank you in advance.

      Hello everyone, 
      After reading a lot of post I still didn't find a solution for my problem.
      I have An Aquaero 5 XT with a D5 pump and a MPS sensor connect with Aquabus. I cannot get the MPS pressure nor the pump speed when they are connected on the Aquabus. If I connect them with USB, it works well and I have both datas in Aida64.
      Does anyone have an idea to help me?

      AIDA, 6.00.5122, is unable to identify serveral new Windows SKUs, incl. Windows 10 IoT Enterprise (0xBC).
      AIDA reports Windows 10 Professional instead of Windows 10 IoT Enterprise …..

      Hey there,
      I recently upgraded my pc, i changed 3 things:
      MB: Maximus XI Extreme
      CPU: 9900k
      Cooler: Ryujin 360.
      Since then aida64 takes a very long time to start, become randomly unresponsive for random amount of time, sensor panel too. Aida64 never crash, it just become unresponsive randomly for a random time.
      I uninstalled Aida, did registry cleaning, rebooted, re-installed Aida and same thing is happening.
      Any help would be appreciated, thank you.

      We've added support for Matrix Orbital GTT color graphical LCD displays. The only connection method currently supported is USB.

      You can enable the LCD device from AIDA64 / main menu / File / Preferences / Hardware Monitoring / LCD / Matrix Orbital GTT. You need to have the appropriate Matrix Orbital USB LCD drivers installed, and the LCD to be connected to a USB port.
      Note: GTT displays implement a slow serial connection which makes frame updates a bit sluggish.
      You can find the new AIDA64 beta update at:
      Please let us know if you find any difficulties enabling or using this new feature. Also let us know if you've got another kind of LCD device that is currently unsupported by AIDA64.

      When you click the "Collapse All Windows" button (Win + D) on Windows 10, the SensorPanel is located behind the windows taskbar.
      My SensorPanel has the options "always on top" and "prevent from being minimized".
      I`m using version AIDA64 Engineer 5.90.4229 Beta.
