MacBook Pro 13" Audio Output sound quality terrible after Lion upgrade
Hi guys,
I have recently upgraded my 2011 MBP 13 to Lion, and ever since have had terrible audio out sound quality, i.e. it is 'grainy' and full of feedback - very unpleasant to listen to.
Is anyone else in the same boat and does anyone have the solution to my problem?
Thanks,
Sam
Sorry for the late reply, yes mine does does recover but I still think it is the same issue with different levels of severity. This is a guess but possibly my higher spec Retina MacBook Pro can work its way through the issue where your 13" MBP can't or can't in a reasonable amount of time.
I have also thought that it is related to window server and was wondering if someone else would bring it up as semi-confirmation since 2 people would have to came to the same conclusion, yes I am weird you don't have to tell me. I am thinking it is possibly related to the lower priority for background apps; it gets caught thinking every window is in the background, chokes, and does not know what to do which is why the cursor will still move since it never gets "backgrounded". As for the caps lock, it is pretty much hardware based which is why we can have a virtual machine not read the caps lock on someimes if it is turned on when the VM is started.
I wish Apple would have more testers so things like this would not slip through. I see more complaints like this when there are external displays on MacBooks than single display iMacs/Minis. Something that may not be tested enough since it requires more specific circumstances.
Sorry, I don't know how to restart window server without the terminal. I would have loved to test the theory since that would answer the question of what is at fault quickly.

15" 2.53Ghz Core 2 Duo MacBook Pro - kernel panics about every 5 minutes after Lion upgrade
I just recently upgraded to Lion and since then have been plagued as it seems many users have been with kernel panics after the upgrade. Have repaired disk permissions, analyzed the drive with diskwarrior, swapped out the memory, unplugged all external devices, and shut down all unnecessary applications to no avail. Anyone have any idea when this is going to be fixed by Apple? My laptop is pretty much useless and formatting and going back to Snow Leopard is a rediculous option since I really do not want to spend a day or more reinstalling all of my applications just to get to a workable situation until Apple gets their "stuff" together. C'mon Apple - we expect more from you than this!

HT202730 Macbook Pro Optical Audio Output Toggles On/Off
My Macbook Pro optical audio output seems to switch off with a loud click when sound is not playing for a few seconds.
Then, when sound resumes, there's a delay as it switches back on.
Is there a way to stop this toggling?
And please don't tell me to check the connections.
I've already tried different sample sizes and bit rates to no avail. It seems as if the system is switching something when there is no audio being played, then switching it on again. Even if the playback is only on pause.Reset PRAM. http://support.apple.com/kb/PH18761

Using Macbook Pro's Audio Output
Hello
I'm considering a purchase of an Apple TV so I can stream films up to my projector which is on the far side of my room. However my Macbook and speakers are on the other. Is it possible to stream content to the Apple TV but use the Macbook's audio output (either via the Macbook's headphone socket though preferably via a sound card) and send that into the speakers?
Thanks in advance.
DomPoop. OK thanks for the clarification.

Audio output has stoop working after mavericks upgrade
a few weeks ago i noticed that when i plugged my audio cable into the headphone jack it wasn't working. i checked the sound preferences and mysteriously this had changed setting to mute. i unmuted it and all was well. i have been away and not used my laptop but updated software yesterday, pages, numbers etc and today when i connect my audio cable to the headphone jack it doesn't work even when system preferences show mute to be switched off.
what on earth is going on with apple????? Why so many problems with mavericks? why can't they just leave us all alone!!!
The problems I am having with mavericks is making me think long and hard about whether I will buy another apple lap top in the future.UserIsNamed wrote:

Macbook Pro: Play and record sound at the same time
Greetings everyone,
My brother and I have are going to switch go a mac, preferebly to a macbook pro. we used windows so far, but the frustration has grown extremely huge, so it's time to throw off this junk.
We've been working with sound a lot and many times we recorded any sound which played through the computer: that means sound and music from dvds and games or other sources, we couldn't get anywhere else. What we did is simply letting the game or dvd play and record the audio at the same time.
I've testet this functionality in windows via bootcamp on a macbook of friend of mine, but NOT the macbook pro version. It's wasn't really that good as I thought. Sound quality was below what I'd expect.
So here are my questions:
- Does the macbook pro have a better sound card, which enables simultaneos play + record?
- Is good record quality bound to a software I need to use?
Thanks for your replies.Apple don't have separate "sound cards" like PC's , Martin. The necessary hardware is proprietary , and built into the logic boards.
Both of them have high quality combined optical digital input and audio line in, and combined optical digital output and audio line out. You can also attach various USB or firewire audio input and output devices if you wish. So as far as 'quality" goes, it depends what you are playing them through more than anything else. The inherent audio abilities of both are pretty danged good when using Mac specific software. That is why the music industry love 'em!
Or are you just talking about sound quality through the built in speakers, which are, of course severely limited by the amount of space available, though I've heard far worse from many PC notebooks!?

Logic Studio, MacBook pro, M-Audio ProFire 610, M-Audio Axiom 61
I'm just about to get the above: Logic Studio, MacBook Pro, M-Audio ProFire 610 and the M-Audio Aziom 61, and want to know if any of the above (Logic Studio and MacBook Pro excluded) are a big mistake. I've been using an Aluminium Powerbook 17" 1.33MHz, and M-Audio MobilePre USB, and an Edirol controller, with guitar rig (and Controller), and Logic Express 7.
I need a set-up that will work as well in the studio, as it does on stage. We tend to plug everything in to the powerbook at the moment, and use Reason to power the synths, guitar rig for the guitars and bass, and logic express plugins for vocals etc.
Anyone have any experience with any of the above?
Cheers,
AdamHi Zuelito,
Please read my first paragraph again:
"I gotta RESPECTFULLY take issue with every point you bring up about M-Audio stuff, Zuelito..."
I'm not sure how you can be "slightly put off by the tenor" of my post given everything I said, with the one possible exception being my line about MOTU making crappy hardware - and that was based on personal experience. And while we're talking about the opinions of others, feel free to peruse the Unicornation board - it's full of MOTU users talking about firewire port failures and other hardware issues - so it appears neither of us is alone in our experiences
Seriously, if I was in some way brash or offensive in the way my post came off, I publicly and sincerely apologize. I really try to think about what I say (and how I say it) when posting on the 'net, for this very reason. I thought I simply stated my experience in an informative manner; again, please re-read my post - I hope it comes across as intended.
For what it's worth, I will say (even more clearly) that I've always loved MOTU products in terms of feature set; maybe that's why I've owned almost every product they've ever made! However, in my environment, I simply can't risk hardware failures, and their stuff has let me down too many times to keep rolling the dice. I will also divulge that one of their top tech support guys has acknowledged the firewire port problem. That's a shame, because they do make great stuff, conceptually. I really wish I could take a chance on that new 896mk3, but it ain't gonna happen for me; 6 dead firewire ports is enough of a failure rate for me to give up on them. To be fair, this probably isn't an issue for fixed installations, but I have to make these connections daily while on tour.
Also, I did NOT categorically state that "M-Audio stuff is better than MOTU." Again, if you re-read my post, it should be obvious that all I'm saying is I have a newfound respect for M-Audio, as of the new ProFire series. I also said in my first paragraph that I shared your opinion of M-Audio for a long time!
If this were all about M-Audio's 410 vs. MOTU's Ultralite (or other competition), we probably wouldn't even be having this discussion as I would have agreed with you - but the original poster specifically asked about the newer 610 with Logic, which is what I'm using on one of my rigs. I simply offered my personal experience.
As for drivers, I've not had any problems with M-Audio or their level of support. Just the opposite - they really seem to be on the ball and are way more communicative than other mfrs. I don't know of any other mfr. that supports each OS subrelease in detail like they do, and their development speed seems as fast (if not faster) than anyone else.
Finally, until now I've only owned a few M-Audio pieces (410, 1814), but I can state that they've been flawless. Their audio quality was not 'high end' by any stretch, but I only used them for utility purposes (writing rigs on the road, etc.). Like I said, my main studio stuff has been RME or Apogee for years, and that's the quality level I'm used to - which is why the 610 really surprised me. I also have several friends who do a LOT of touring, many of which rely on M-Audio hardware (mostly 410s). One guy's unit doesn't even have any paint left on it from road abuse - but it still works like a champ after 4 years.
So anyway, this is all just my experience. Hope it doesn't come across as anything but that
Peace,
Jim -

thank you in advance
macbook pro mid2012 i7 (here is my e-mail adress : [email protected])You should take it to an Apple store or an AASP (Authorized Apple Service Provider) Carefully inspect the hinge joint and make sure there is no debris that you can see, you can try carefully sliding some sticky tape thru the joint to clear any loose stuff out. But this sounds like there might be more going on here, and the hinge is something that you do not want to fool with.

If you have a Seagate 500 GB 7200 RPM drive model ST9500420AS or ST9500420ASG, there is a widely reported problem with MacBooks that causes intermittent clicks and beeps. If that is your scenario, google for details.
