Sound stuttering after Mountain Lion install

Hi d0nny2600,

The current Saffire 6 USB driver is not yet compatible with Mountain Lion. Please download our Mountain Lion-compatible beta driver from beta.focusrite.com. You'll want to get Focusrite USB Driver 2.6b3.

Best,

David Tichauer // Focusrite Technical Support

I may receive some form of compensation, financial or otherwise, from my recommendation or link.

Celsius or Fahrenheit-scale?

@DavidFromFocusriteNovation do you have a tip for the others of us who have the same issues with internal sound cards?

@sixfour there is a third library cache: /System/Library/caches

I'll try this method. There is no other possibility for me at the moment to remove the stuttering 😟

I'm afraid I don't since we only make the drivers for Focusrite products; we don't have much insight into the workings of other manufacturers sound cards.

I also have major sound problems since ML. Especially when Mail was checking emails, I got bad crackles in all apps that run audio.

It happened on three completely different macs: a MacPro (2008) in my studio with high end audio gear, a MacBookPro (2010) with CoreAudio, but also some Audio Apps, and my wife's MacBook (2009).

No problems before, crackles since ML.

I had a look into console and detected an error message from the sandbox that came up every time I herad the crackles. Like this one:

18.09.12 08:23:12,967 sandboxd[13727]: ([13476]) Mail(13476) deny file-read-data /Library/Preferences/com.apple.mail.plist

Repairing permissions did not help, the error persisted.

So I just deleted the two files in the /library/preferences folder

com.apple.mail.plist

com.apple.mail.plist.lockfile

and the problem was gone. At least with mail. But I still get occasional crackles from other apps. It must be something deeper in the system. Maybe with sandboxed apps, or on certain disk accesses.

Feedback sent.

Delete all your caches.

I didn't delete that, it worked for me after deleting cages in user account folder and Mac HD library folder.

No more stuttering.

Did not work for me, unfortunately 😟

David,

Thank you very much for this. I appreciate you taking the time to come here and solve this for me.

My audio issues are now gone. Thank you for that.

Now to catch up on the backlog of work I had to put on hold!!

I have reset PRA and deleted cahce, didn't solve my problem. Only SMC left to try but I have absolutely no confidence in this fixing it either. Apple should be ashamed. How many people wasted their money on moutain lion only to make their expensive computer useless.

edit: I will unsubscribe to this thread now as it totally exploded.

Can we please have a representative from Apple make a post on this thread to confirm whether this MAJOR fault is being investigated please?

With over 15,000 views this is clearly a topic that is causing interest /concern in the community.

It is COMPLETELY UNACCEPTABLE that an upgrade provided by a company renders their product unstable without the option to uninstall it.

If the continued crashing of my machine is caused by overheating brought on by Mountain Lion which subsequently causes hardware failure then I will be seeking compensation from Apple.

You are completely right.

But Apple is not reading Apple support forum (and I think none of us is an Apple representative).

The only way to contact Apple ist the feedback form:

http://www.apple.com/feedback/macosx.html

😟

Yeah, already left feedback twice. Not expecting a response, it'll just be dropped into the database and used for statistics.

The really annoying thing is that Mountain Lion hasn't actually provided me with anything new that I want or need, you just assume an upgrade would improve performance generally. It really feels like I've actually spent money to make my computer crap, when it was pretty darn perfect beforehand.
