Problem with Audio on iMac still unsolved
I'm running Windows 7 using Boot Camp on my iMac 24. Everything is fine except the audio through the speakers, which is absolutely horrible. At first, there was no audio at all, but I installed the drivers on the OS X disc. The audio then worked but the quality was just terrible. Switching back and forth between OS X and Windows, playing the same songs at the same volume levels in iTunes, the difference is substantial. It's unlistenable on Windows 7.
I downloaded the most recent driver from Realtek and that didn't solve the problem. However when I plug headphones in the back and listen through the headphones, it sounds fine. It's only through the speakers that it sucks. Any suggestions? |

![]() Anyways, I still haven't solved the problem, but I came up with a "solution." I plugged external speakers into my iMac and those work fine. It's not ideal, but it's good enough for now. But it's weird. External speakers sound great with the driver, but the Mac's internal speakers don't. |

Hello,
I think the problem happens because OSX corrects the frequency response, while Windows drivers don't have any processing. I measured 24" iMac response and created DSP code for Windows7 to apply the correction, and the software is available at the link below. The solution doesn't work on Windows XP or Vista however. http://yohng.com/software/imacsoundfix.html I also noted, that the microphone is switched on by default, which creates unnecessary feedback in the sound. Please check the web page for the instruction on how to switch the microphone feedback off. The measurements were taken from my 24 inch iMac, so it's hard to say for sure, how this algorithm will perform on a computer, which acoustically is different from 24 inch aluminium iMac. Thanks, George. |

Awesome!
That did the trick - thanks! I think Apple needs to get ahold of this fix and incorporate it in their drivers.
