    Hi, I recently bought Aspire v3-574g, and could use help with few problems:

    1. After buying new laptop I did clean install to delete all crapware that comes with it, but after it bass dissapeared when using headphones.
    • I installed audio drivers from Acer site.
    • There are no "enchancments" or simillar tabs in realtek manager.
    • If I rollback drivers to stock: "High Definition Audio Device", bass returns, and so do "enchancments" tab, but "Dolby Digital Plus" stops working.
    • Is there any workaround? It seems like drivers installed incorrectly, or something didn't installed at all.........
    2. "Event Viewer" often shows few messages like this:

    "The speed of processor 0 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report"

    As far as I understand, something limits my processors power. Is there any way to fix it.

    If someone takes his time to answer any of my question, thank you very much! :D

    EDIT: I forgot to add that it shows high latency with latencymon, main problem is - ndis.sys, both ethernet and wi-fi drivers are updated, so maybe this is connected to CPU being limited by sys firmware?

    you most likely removed some component of the dolby audio processing when you were cleaning out the "junk". Try uninstalling all dolby / realtek audio related stuff, reboot, then run the installer from the stock acer audio drivers from their support site.

    Also, latencymon is known to show entirely incorrect results with windows 8, 8.1 and 10. A new version is being developed. Best not to worry about it

    Thanks for help! :D You see, I didn't uninstalled nothing, I just did clean windows install (win partition was reformatted), then I downloaded drivers from Acer support site and installed them.
    I tried posting at Acer forum, but I got no helpful replies, except "try to uninstall drivers and install again", which I did about dozen times.

    I did latencymon test to find out why "ïnterrupts" are jumping from 0.2 to 1.0 CPU. Which isn't normal I guess, my 4 year old laptop constantly maxes only on 0.4 "interrupts". Do you know any other soft that would help me troubleshoot "interupts"? :)
