Audio Delay on iMac USB vs. Digital Outputs?
Most annoying problem is that I have two other systems at home and often run them all at once, from the same source. One out of sync system is not good. Secondly, video/audio from the iMac are out of sync, basically unwatchable. Despite the response form M2Tech, I've been informed elsewhere that this is a problem with OSX drivers and not an issue with Windows. |
. They know about the issue according to this article,,,,, M2TechÂs Mac OS X driver for the HiFace introduces a fraction of a second of delay between the source and output, which means that when youÂre watching film or TV video, lipsync will be lost, with voices playing behind the pictures. The M2Tech HiFace's designer Marco Manunta explained that the Mac driver works differently than the Windows driver: the Mac version doesn't work with fixed-size packets, so a large buffer is needed to avoid 'flux distruption' when several small data packets are sent, instead of one regular size packet. http://www.pcadvisor.co.uk/reviews/pc-peripheral/3250187/m2tech-hiface-review/ . |
. I wonder if the delay would be there if you were running Windows on your iMac? I would think not but I guess you would have to try it. I have Windows 7 and Parallels running at the same time as Lion on my Mac Mini and it works very well. When you plug in a USB device it asks if you want it to be hooked up to Windows or Lion or both. I bought a used copy of Parallels on Amazon for around $50 and you would need a full (not upgrade) copy of Windows. . |
