Audio sounds like 78 rpm record played at 33 1/3

[nfgaddress]

I understand this used to be a problem and was fixed with an update. But I guess it is back. I use v.Version 11.0.7.0. Talk radio on IHeart sounds like an old 78rpm record played at 33 1/3. This happens only in Slimjet. IHeart plays OK in Chrome.
Is there a fix? Thank you
