On all my ios devices (iphone 5s, iphone 6s, ipad air, ipad pro) when I fast forward in the Music app on ios 11 the sound is kind of hissing (not sure how to describe it better). This is particularly noticeable with voice, rather than music. Makes it much harder to understand the words when fast forwarding. It's very different from how it was before. I have a bunch of spoken word tracks where this is highly noticeable and quite annoying. To make sure I'm not imagining it I restored my 5s to 10.3.3 and the hissing is completely gone. Is anybody else seeing the same?
