AM Audio Muffled

Today when I went to WWV, I noticed that I cannot hear any audio frequencies above 100hz unless I use LSB or USB.  AM is completely muffled.  The problem exists on all bands.  I even went to the AM broadcast band and the problem is still there.  I rebooted the radio several times with no change. The problem is most noticeable on the PC but not much better on the Maestro.  Strangely enough it seems to work just fine on my iPad.  It acts like the filter setting have no effect on PC and Maestro.  Has anyone else run into this problem?  I'm running 3.1.8.

    Sorry, no answer, but what release of SSDR are you running? What has changed with the radio since the last time you used AM successfully (SSDR upgrade, Windows update or upgrade)? That it works fine with SSDR for iOS points to a problem with SSDR, the questions are: Is the problem in the OS? Is the problem in SSDR? Or is the problem in the user settings? The most likely issue is going to be user settings, but all three are possible. I hope this helps you find an answer. Ken, N2VIP

    You cannot mis-match SSDR with the version in the radio.  Its 3.1.8.  I do not disagree that it could be a setting somewhere, but even default setting make no difference.  And why both on PC and Maestro?

    I can change it from 5.5k to 20k and it makes no difference.

    That's crazy! I'm glad you found a solution, but I never would have thought the speakers were the issue. Reminds me of the time I had a computer that kept BSOD for no reason. I went through every part of that computer swapping drives, power supply, etc. before I tossed the computer on the recycle heap, I swapped the RAM. That fixed it. Twenty years in IT and that was the first and only time I had RAM fail.

    And I have a Acer Aspire that wouldn't change screen brightness at all until I downloaded a new bluetooth driver.
