  1. high defination audio controller causing system interupt high cpu usage


    cpu usage at 40 - 65% because of system interupt process when i check drivers i found disabling high defination audio controller

    let cpu usage between 5-15% i check these issue in windows 10 1703,1809,1903,1909 might be motherboard issue but i chech using linux cpu usage in linux is 0-3%.

    :)

    High CPU usage with 'system interupts'

    High CPU usage with 'system interrupts'. However, the usage decreases when the task manager is opened. On opening the task manager, the system interrupt is visible for a few seconds and then the CPU usage goes down.

    "System" process with high CPU usage

    I have exactly the same issue (high CPU usage) on a brand new HP ProBook 440 G5 (i7-8550U, pre-installed Win 10 Pro).

    I am pretty sure that there is a problem with audio drivers when the computer wakes up from a sleep mode. I first observed that process flow.exe (audio bloatware provided by HP/Conexant) was consuming (after waking up) ~10–15 % CPU. Here's what I did:

    • I have updated Windows to 1709, build 16229.251 and installed all updates --> Nothing has changed.
    • I have updated BIOS to the latest version provided by HP. --> Nothing has changed.
    • I have run Windows troubleshooting and HP Support Assistant checks --> No problems found, nothing has changed
    • I have manually updated Conexant ISST Audio Drivers (via Device Manager -> Update drivers). Windows installed a newer version. -->
      CPU usage by flow.exe has disappeared, but process called System in thread ACPI.sys+0x21cb0 started consuming ~20 % CPU.
    • I have uninstalled all Conexant software&drivers and manually installed generic High Definition Audio Device drivers provided by Microsoft (Driver Date: 21.02.2018). --> ACPI.sys+0x21cb0 still consumes ~20 % CPU.

    Same issues are discussed in these threads on HP site:


    The result is I cannot use sleep mode (as advised by this post:

    ).

  4. high defination audio controller causing system interupt high cpu usage

    WIN10 1703 update cause Explorer.exe high CPU usage

    Hi,



    Glad you reached out. First, we would like to know if Explorer.exe
    is the only cause of high CPU usage. Because the common cause of high CPU usage are the following:

    - Windows 10 Memory leak after the update.

    - Driver incompatibilities after the update.

    - Multiple startup applications





    We'll be waiting for your update.
