ibt Posted January 15, 2012 Share Posted January 15, 2012 Never had problems with Aggregate Devices under Snow Leopard - created them, quit Audio MIDI Setup - job done. Recently got a new machine with Lion (10.7.2) preinstalled, and have noticed that any Aggregate Devices I create now are not being saved. They work without issue once they've been created, for that day's session - but once the Mac has been shut down and restarted, nada. (In case it had anything to do with my MOTU Ultralite, I've created other Aggregate Devices (not including the MOTU) for Soundflower and Built-In options. But these aren't available on restart either.) Anyone else having this issue? Anyone know of a fix? Quote Link to comment Share on other sites More sharing options...
ibt Posted January 18, 2012 Author Share Posted January 18, 2012 Have any other 10.7.2 users experienced this issue? Quote Link to comment Share on other sites More sharing options...
punxpunx22 Posted February 3, 2012 Share Posted February 3, 2012 im having the same issue! i have to delete and re-enter my devices every time! Quote Link to comment Share on other sites More sharing options...
punxpunx22 Posted February 7, 2012 Share Posted February 7, 2012 ok i found out how to fix it... i called apple and the first tech, had no idea what i was talking about. so, she went and asked somebody. finally she told me to do the following; go to hd/library/preferences and type the following in the search bar: com.apple.audio.AggregateDevices.plist now i had to figure this part out my self: before you delete that plist file, first you must delete the aggregate devices you created. once you have done so, close your audio midi set up and delete the plist file. shut your mac down and restart and create your new aggregate devices. worked like a charm. one other thing i did do was repair my drive. not sure if that had something to do with it to. so if it doest work for you try disk repair and do the plist delete file steps again. disk repair is ran by shuting down your mac and holding command and R (at the same time ) as your mac starts. select your Language, next select disk utilities and run repair disk. once you have repaired your disk, on the top left corner hit restart and follow the steps above again. hope this works for you!

ibt Posted February 16, 2012 Author Share Posted February 16, 2012 That com.apple.audio.AggregateDevices.plist file does not appear in my HD/Library/Preferences folder* at all! And isn't being created when I set up a new AD - which explains why recently created ADs don't appear on reboot. And, keeping an eye on that Preferences folder, there isn't even a '.temp' .plist file created. Hmmm. Maybe this has something to do with having replaced the original HD. I used CarbonCopyCloner to transfer everything to the new HD, and maybe some files went missing in the process? But Aggregate Devices do still work - just that the .plist is not being created. Strange. *Or in User Library Preferences folder either Quote Link to comment Share on other sites More sharing options...
ibt Posted February 16, 2012 Author Share Posted February 16, 2012 Problem solved: in the HD/Library/Preferences folder, there is an 'Audio' folder containing two .plist files : com.apple.audio.SystemSettings.plist com.apple.audio.DeviceSettings.plist I deleted these and rebooted. (Lion created two fresh .plists on reboot.) Creating Aggregate Devices now works as expected. Quote Link to comment Share on other sites More sharing options...
punxpunx22 Posted February 19, 2012 Share Posted February 19, 2012 great!!! glad you got it working! for some reason i think lion or the imacs have issues transfering data from back ups and what not. when i restored my mac from time machine i had all kinds of things missing. anyway, glad its all working for you!
