OS X 10.10.3 & QuickTime 10.4 - 2x Speed - No Audio

same problem here

Ditto!

2014 Macbook Pro 13, Yosemite 10.10.3, QT 10.4

Any help out there?

Same issue. This seems like another one of apple's "improvements".

I ve got same problem at normal speed too and that affects iphoto wich uses quicktime for playng videos. Have picture but no sound. these movies play with sound in VLC... so they are not broken. I talk about .mov movies imported from my camera.

I am on Yosemite 10.10.2 !!! and QT 10.4

Same problem here on my MacBook Air mid-2013, Yosemite 10.10.3; QT 10.4 😟

Same problem on 2010 Macbook pro with 10.10.03 and Qucktime 10.4

I hope it is not one of "apple's improvements" and they can fix the bug.

Experiencing the same. I did find that I can work around the problem (somewhat) by holding the Option key while pressing the >> button, which increases the speed in 1/10 increments. I can get up to 1.9x speed and still have audio, but once I hit 2x it goes away. Hope that helps some of you in the short term.

Great tip! Thank you for that.

Yes, 1.5-1.9x speed will be wonderful and adequate until/if this gets fixed.

thanks, now is up to 60x... no audio but it's crazy... 1.9x with audio. Sometimes 2x is not enough. Apple we need a solution 3to5x faster audio no video or 1/60 frame. thanks. 🙂

Same issue. 2015 Macbook Pro 13".

Had this same issue, and it is too inconvenient to option up to 1.9x speed every time while trying to watch a lecture I am taking notes on. I ended up downloading VLC media player and it allows me to stay at 2x speed without ever changing.
