Kernel Panic due to audio device

Question

Recently my iMac (24-inch, Early 2008) started crashing on a daily basis. (I would get a grey screen with a message that the computer has to be restarted). Upon restart the computer would display a crash report. All the reports had these stack trace in it: Kernel Extensions in backtrace:         com.apple.iokit.IOAudioFamily(1.8.6f18)[8D690452-BF17-3DA0-BCAD-F1BCF1495926]@0 xffffff7f80e96000-&gt;0xffffff7f80ec2fff            dependency: com.apple.kext.OSvKernDSPLib(1.3)[3D9EA2A9-E433-3F0A-AEFC-24E4B964505E]@0xfffff f7f80e90000I tried running diagnostic tools that came with the iMac, I tried reinstalling the OS - nothing helped, computer keep crashing. Finally because of teh audio family reference in the crash report, I decided to try to disable the audio. The way to do it I found was to move directories IOAudioFamily.kext/ and IOAudio2Family.kext/ from /System/Library/Extensions/.I did that and after I restarted my computer the audio features were gone. On a positive side, the computer has not crashed since I have disabled the audio.Would you have any suggestion how to make the computer work properly - with audio enabled and no crashes. Is kernel panic likely to be caused by a software or a hardware problem? How to fix the issue with the audio?Thank you,Michael

You probably have a logic board or audio board hardware issue. Take your Mac to the Genius Bar to have them take a look at it.

I am not sure it would be cost effective to invest hundreds of dollars into a four-year old machine. Is there anything I can try myself?Thank you,Michael

bispymusic · Answer

You could try purchasing an inexpensive USB audio interface. It may give you a way to pipe your audio out through USB instead of the actual audio IO board. You could also take it to the Genius Bar for a free appointment just to have them run diagnostics. It doesn&#x27;t cost money unless you opt for a hardware repair and they may fin something with their diagnostic tools that we can&#x27;t really uncover here.

rkaufmann87 · Answer

Michael,Please post the complete KP report, just posting part of it isn&#x27;t correct. If you suspect it&#x27;s a hardware issue then please run Apple Hardware Test in Extended Mode, if no errors appear after the first run then rerun another 2-3 times. AHT may not pick up errors after the first pass so you should let it run several times to be sure. If it provides error codes take those along with the machine to your local Apple Store or AASP and they can provide a professional diagnosis.

Your KP begins when it reaches com.makemkv.kext.daspi  You need to locate what app that comes from and and either update it to a version that is compatible with the version of OS X you run or uninstall it following the developers recommendations. Once you done one or the other the chances are very good the computer will be just fine again.

Thank you for the pointer! I did get rid of the MakeMKV program and DASPI kext. Alas, after I restored the audio family kernel extensions, the computer started shutting down again with the message below:Interval Since Last Panic Report:  527113 secPanics Since Last Report:
