Helix suck at audio-playback?

When I use Helix for recording and use it as Output device, it really sucks ? It makes weird clipping-noises all the time and some times it actually sounds lige some sick Ring-Modulator. 
Can Anyone explain this ? Is it due to the fact that USB is outdated ? or what is going on ? 

Sample rate is set to 44.1 in both Helix and Logic.

There is something wrong with your specific setup; it's not a flaw in all Helixes. I've been using the Helix extensively for audio playback and it has been flawless, on Mac OS X 10.9 and Windows 8.

 

You may be using Mac OS X 10.11 El Captian, which has issues with the Helix.

Yeah, I am using El Capistan... 

Do we know when this Issue will be fixed ?

 

The latest developer preview of El Capitan seems to have fixed it for me, but the poblem is complex. Basically the kernel is wrapping up access to the USB hardware in a completely new technique, and it's causing different bahavior across different models of apple hardware. There's no telling when Apple will cut the official update, but I'm crossing my fingers for next week!

Strangely I was having the same problem running OS X Yosemite. Im running Logic X on a Macbook Pro.

 

Its killing me....i just want to get on with recording and using the Helix as the Audio Interface really would be the best way to go.

Very disappointing.

 

@Davesheremata....Do you know this to be fact Dave?

About the Kernel/USB wrapping or about whether the next release fixes it?  

 

As for what's causing the glitches in El Capitan, I can't %100 say that the kext/hardware wrapping is the root cause, but I did believe what I read when I read it, and I'm a pretty dang good software engineer.  I wish I could find the thread again on the mackintosh forums... 

 

As always, no one has any idea when Apple will cut a release candidate.  I had all the same issues on the latest official El Capitan release, and also on beta3.  With both Beta 4 and Beta 5 on my 2010 iMac the USB glitches have been gone, having played and listened to it for many many hours, and I've left the Helix running as the audio device for several days - where upon I return, the audio still functions properly without degradation.  

 

Anyhow, I'm going to be much more careful about future upgrades to OS X on my DAW box in the future!
