Built in Subwoofer Cutting Out

My early 2011 Macbook pro is experiencing some sort of problem with the built in speakers. Essentially, the subwoofer keeps cutting out and I'm not sure why that's happening. At first I thought the speakers were messed up so I got them replaced at the Apple store and things were fine for a good 2 weeks and now the problem is back. What could this be? Logic Board issue? I did a fresh install of OSX and the problem persists.

Hi,
The Apple Store wouldn't have sanctioned work on your MacBook Pro unless they believed there was a genuine fault present. If it's persisting after the repair/replacement, just get back in touch with AppleCare, and take it from there. Let them deal with it
Good luck,
S.

Subwoofer Cuts Out

I've got a 2011 13" Macbook Pro (i7, 500GB HD, 8gb of RAM, running Lion 10.7.3) and the subwoofer keeps cutting out... And also I no longer have a start-up chime. This seems to have been an ongoing problem since I upgraded to Lion in July. Resetting the PRAM and SMC sometimes fixes it, but lately not. I've already had my right speaker and subwoofer replaced under warranty once, but the problem persists. I've also reinstalled Lion a couple times.
Is this a software bug of somekind? Any idea about fixes? Or is this some kind of known hardware issue?

If you give your 2.4GHz and 5Ghz frequencies different SSids i.e add a 5 onto the end of the 5GHz one, then set your devices to only use that SSid by deleting the 2.4GHz one from them this will stop them logging onto the 2.4GHz. Downside is that they won't automatically switch between the two if they can't get the 5GHz frequency. This might not be a problem if the 5GHz give you good coverage through out your house.
You could also set your devices to only use the 5GHz frequency in their advance wireless settings but the downside would be that they would not connect to the 2.4GHz frequency if you were wanting to use it else where unless you changed the setting back.

Sound cuts out after any given amount of time, only way to turn back on is to reboot.

For reference, I am using a fully up-to-date mid-2012 model rMBP. Attached to my MacBook via USB I also have an M-Audio KeyStation 49i, which is where I have my headphones plugged in (probably not related in any way, but just noting this).
I first encountered this issue while using Chrome and listening to music on SoundCloud with Garageband open after the last Mavericks update yesterday. I initially thought it was a Chrome bug, and in doing some research, I found that other Chrome users were having the same issue as me, but it was related to PepperFlash (a version of the standard Flash player), and disabling it in Chrome Canary fixed the issue for them.
Unfortunately, it did not fix the issue for me, but I have refrained from using Chrome since then and stuck to Safari to ensure that it's not two issues with the same outcome.
Then I stumbled across all of the Mavericks users that are having sound problems; anything from crackling/popping to not working at all. It seemed, though, that everyone that was having the sound cut out for them entirely were not only having this happen after their laptops came back from sleep mode (which is not the case for me), but were able to fix it by restarting Coreaudio[d] or -- if they had been using the headphone jack on their Macs -- they just had to plug it in again and take it back out. Neither of these worked or were applicable to my situation. Some were able to get it working again by resetting the PRAM/NVRAM, and a few others seemed to be able to bypass the issue by using Soundflower, but neither of these solutions worked for me either. The only way I can get sound to work again is to restart my computer entirely.
After doing so, I am only able to listen to audio for a certain amount of time. It seems to vary depending on how much memory the task is taking up. Like I'll be able to listen to a track or two on SoundCloud, or attempt to record into Garageband for five minutes or so. If I'm in a Garageband project that already has a lot of tracks, I'll be lucky if I can even get through a few seconds before it cuts out entirely. There are very quiet crackling/pop sounds every once and awhile, but it is hard for me to distinguish if that is just the natural state of the hardware I am using or if it is related to background system sounds.
I'm at wit's end trying to figure out what the problem is, mostly because there are so many others with similar issues and varying hardware/software setups that it's hard to track down exactly what my own situation is.
I'd like to know where I should be exporting any error logs from so that someone can take a look at this issue.
Thank you.

After doing some additional testing, I was able to get the sound working again without rebooting by:
1. Unplugging the MIDI device.
2. Resetting the audio input and output to "built-in".
3. Plugging back in the MIDI device.
4. Changing the audio input and output back to the MIDI device.
Still, though, the sound only lasts for a little while, and there doesn't seem to be anything indicating how or why it stops.

I have a iPhone 4S and when watching videos on the internet sound cuts out as the video is playing. The rest of the video plays with no sound. Sometimes when I pause It and play again sound comes back but not all the time. can anyone help?

The "restore disk" is built into the Mac. See About Recovery.
Need more specifics about what error messages you got while installing Adobe Flash.
However, you can almost avoid Flash altogether by setting YouTube to play the HTML5 version instead.
Click the Try something new! link at the bottom of the YouTube page.
I don't know about the sound issue. Might be hardware as you think. Try other headphones to check.

Macbook keyboard cutting out at times, 10.5.1 installed.

Hello.
Here's the problem. I have everything back to normal on my Macbook, OS X Leopard, boot camp, windows, and etc. However, being the upgrade conscious person, i upgraded my Mac to 10.5.1, and for some reason, my built-in keyboard will cut out at times. There will be times when it's on, and when it's off. And I mean its Off by it actually not functioning. Apple SHOULD UPDATE the Macbook firmware. This has already became an annoyance after a half hour of experience.

Discussions is the hospital for people who need help.
People that have something not working properly check here and find others with the same issues and assume they are part of a large majority.
Apple have sold 5 million copies of Leopard already plus Leopard on over 2 Million new computers.
With that large an installed base there are bound to be some problems especially with all the internet downloads available that may have been made for previous operating systems but not made for leopard.
If you do an upgrade and have downloaded something incompatible with Leopard it will still be there after the upgrade and may come back to bite you.
If you have a fairly clean system you may have a minor issue if you have an old font with a problem or a file or files that had sketchy permissions. These can be annoying but no biggy.
If you do an archive and install, you bring in a clean system and need to reinstall programs that modify the system. Bring them and plugins in slowly in case there is a compatibility issue.
An erase and install makes you store your data off the volume and is not much different than and archive and install except you can opt to preserve your network settings.
You can always bring back in you user settings.
The vast majority of installers don't mess too much with their systems and usually don't experience any problems since they have never brought in anything foreign.
People rarely report things that work only when they don't.
Congrats on all fronts.

Kdl40s5100 picture cuts out for about 1 minute then comes back

when i'm watching programs the pictuture (and sound) will cut out then return in about one minute... this will repeat itself about every 30 -45 minutes.... problem does not occur when watching videos - only cable or antenna

New pc just built and using SSD for C drive. Working great for a few days but minimal usage with just drivers and BIOS updates etc. Then yesterday I turn on pc to do a quick Google search and half way when typing a search question the keyboard entry quits and Firefox is not responding. I tried IE and the same thing happened so maybe its a Win 7 thing I use Win 7 64 Pro with 16GB Ram and i72600K. Also, yesterday was a big Windows update night so I don't know if that interfered in background. Today it happened again but after I waited and watched and hit CTRL/ALT/DEL the system came back and was not locked solid the the night before.

Sustained use of Cinema display audio results in noise, choppy audio, then cutting out

When I play a sustained audio stream through my 27" LED Cinema display – for example, listening to my music collection on iTunes – for a couple hours (since I powered on my computer), the audio suddenly gets very noisy and after a few seconds really choppy (+ noisy), and waiting another few seconds it's barely audible (just repeated hints of noise). After this happens, I can press Pause in iTunes, wait a few seconds, then press Play, and the audio is perfectly fine again.
Then, after only a half hour or less, the same thing happens, and I have to do the same thing to fix it. I am always able to fix the audio perfectly fine, but it inevitably craps out again after 5-30 minutes.
If I power off my computer or let it sleep overnight, then come back and play iTunes again, the audio will be fine for a few hours before this inevitably happens again.
I've followed the advice of an Apple support technician of resetting both my NVRAM and SMC, and that had no effect. The Cinema display audio continues to behave the same.
I have the USB for the Cinema display plugged directly into my MBP's USB port (no other USB hub in the way).
I have the latest version of OS X and thus the 27" Cinema Firmware 1.0 update has already been applied (I tried applying it by downloading the firmware update manually, but it refused, saying I do not need this update).
This should go without saying, but this never happens when I play music through my MBP's built-in speakers, or when I play music through external speakers plugged into the line-out port. It's behaviour that happens exclusively through the 27" Cinema display's audio interface.
Thoughts, anyone?
I'm especially curious whether anyone else has had precisely this kind of audio problem with their 27" Cinema display. I've seen many people post audio issues relating to their 27" Cinema display, but most of those problems were remedied by the 1.0 firmware update, and besides none of the problems were described quite like mine (specifically, audio that becomes noisy, then mostly cuts out - it never completely cuts out - and that can be reliably [temporarily] fixed by pausing and playing the audio again).

Can an MBP Sound preferences output to the display as opposed to through usb? I use a mac pro and have those two choices for my mini-displayport 27" apple display.
I am not suggesting this as a fix but only testing various other paths to try to diagnose the problem.
What first came to mind in your description was that you are having some kind of temperature problem. And I think the temp problem lies with the MBP and not the display. To that end you might consider adding one of the temp monitor utilities like iStat Pro, iStat Menus, Temperature Monitor, Temperature Monitor widget, Hardware Monitor, etc. See if there some correlation with the temps shown in some of the readings and your sound problem.

The internet on my macbook pro keep cutting out in OS 10.8..What to do?

Hello,
I purchased a new macbook pro about in early September and ever since I started using it in my home, the internet cuts out constantly. I was using a aiport to connect wirelessly and then swithced to a router provided by my internet company which is Time Warner. I have the fastest package they sell but nothing seems to help. The internet cuts out after about 5-10 minutes everyt time I use the internet and download speeds are nowhere near what they should be for the package I have.
I'm using the newest OS (10.8.2).
Any help is very much appreciated!
Thank you

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers
    Make sure that Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
6. System Preferences > Sound> Sound Effects
    Play sound effects through:
   Select "Internal speakers" and then back to "Selected sound output device".

Can i use keypad without cutting out speaker?

When I need to use the keypad to input numbers while I'm in a call, the speaker cuts out. Sometimes it takes a few seconds for the sound to return, so I lose the answer, usually from an automated system. Other iPhone users say this should not happen. Any way I can fix this, or is the phone broken?

All the instrument and FX plugs are included, and a (massive) additional free download within the Mainstage application will get you all the extra content.

Yes, and memory/CPU issues not withstanding, Mainstage generally works extremely well for this.

Re: Creative Gigaworks T3 Power Cutting Out AS WELL!!!!!

This is a response to the same fault on the gigaworks T3 as mentioned in this post here : http://forums.creative.com/t5/Speaker-Systems/Creative-Gigaworks-5--G550W-Power-Cutting-Out/td-p/430593?
hi! I am from New Zealand. I?just purchased?a set of Creative Gigaworks T3 for just DAY(the first day)! and I am encounter the same kind of problem mentioned in this post/topic . it Shuts off by itself or (power cutting out) . most probably would be the overheating cut off problem as well , all symptoms are the same as described this this post!
I cannot believe this is happening to the whole line of Gigaworks subwoofered speaker systems. I also have the Gigaworks T40 SII and are working mint. but seems like the subwoofered ones are the ones with this overheating cut off problem!!!!!
Man I trusted Creative for its quality of its products as I have always been Ultra impressed for the Creative Cambridge FPS2000 which I had own for the last 10 years until the remote switch became faulty 2 years ago (volume fluctuates), but thats acceptable for so many years of use!! they were the best ones and love them!?
BUT? I dunno about these current line of Gigaworks systems. they all seem to be faulty with this problem
do you think I should get a replacement or just get a refund IF I CAN.
a replacement might do the same thing?
cheers !!
ken

here is an update of what happened to my faulty Creative Gigaworks T3 system.
I returned it the next day the shop opened back from new years which is the Jan 4th, 2010 . I told them about the problem I was having and also printed out the dicussion from this forum on the Gigaworks G550W http://forums.creative.com/t5/Speaker-Systems/Creative-Gigaworks-5--G550W-Power-Cutting-Out/td-p/430593 . which I told them was the very same problems as discussed here and seems to be like a common fault or design problem of the gigaworks (subwoofered) series from creative!!
I was treated in a very bad and unhelpful manner from the store. and straight up. there is no refund!. and they seem to think I was lying about all this and making it up trying to get a refund ?!!
wtf I came all the way back (50km retrurn) waste my valueable time waste gas to muck about na I don't think so!? but to them I was a lier which had nothing better to do. " they say , you say its faulty, but We don't know" and they said , if the supplier say can refund then we will definitly refund... or even we test it out have problem, the supplier will have to test it again to confirm if there is a problem then to see if they will repair or replace. of course I wanted a refund as this a design problem and will happen again shortly!!! I had no choice but to leave it there , so I left it there on the 4th. anyway I was treated the worse I've ever been treated for any purchase at a store
week later. TODAY the 12th Jan. I received a txt message saying " this is xp computer warehouse, just 2 let u know ur creative speakers has been returned from the distributor as no fault to be found, n its ready 4 pick up "
of course there was no fault if it was tested for 5 minutes!!!!!!!!!!!! its the overheating problem after being used for over 2 hours or so. but I'm sure they know about this hard,. how can they not know if its happening all the time. they just can't be bothered, they would of just said "ah f--- it!!"
So i'm going back on sunday 24th Jan to get a refund as they have failed to meet the Repair/Replace or refund policy, if nothing works out then the last thing (which I really do not wish to do) it to Disputes Tribunal at the courts , a bloody hassle and a waste of f----- time! seriously. if creative would just sort it out or even open and fix it I'd be a really happy customer!
but for things that are going now , its definitly not right!
think about it before buying your Creative Gigaworks T3, just sharing my personal experience here , and it ain't good!
I'll keep you updated on sundays results.
what a pain

Logic's synth pad sounds are cutting out

I have noticed that the synth pad sounds (those that are built into Logic NOT 3rd party instruments) appear to be cutting out.
The patch will play for a short while then at some indeterminate point the sound will just die. If I load another patch in that will play, again for an indeterminate time then the sound dies again.
Logic is showing midi notes being input but no sound is being generated.
This is driving me nuts!!
Can anyone help
Mike

Ok I found a solution to this - it seems to be a Maverick / Logic 9.18 and Lexicon bug as it didn't happen in the previous OSX.
Simply remove all instances of any 32bit plugins you have running, I missed a few lexicons thinking they'd be ok. Turns out they were the culprates. Bounce in place on each track and then remove the original track.

Why is my HDMI-connected display cutting out periodically?

I have a Mac Mini hooked up to a 40" Phillips LCD LED 1080p television using an HDMI cable. This setup worked awesome for about six months, but it has started giving me problems this week. I never really used the television for anything besides as a display for the Mini until last week, when I plugged in a couple of different older video game consoles (N64 and a PS2) into the YPbPr ports and switched sources on the T.V. Not sure if this is related or not, but it seems like that's when I started having these probelms. From what I've read about HDMI handshaking, it makes sense that switching devices can mess with it?
Anyway, the visible problem is that periodically, the video AND audio will cut out and the display goes blue. Audio usually comes back a little before video does, and sometimes the Mini will try to play the audio in the interim.
It happens more often when I'm playing videos on Netflix, YouTube, etc., but it has happened when I'm just sitting on the Desktop, not doing a thing. It will sometimes not do it for up to an hour, and then it'll start doing it every five minutes so that you can't even watch video.
I've tried two different HDMI ports. Don't have another cable to try, but would rather not invest the money in a new, good one if that's not the problem. Any ideas?

Something to check first.
The Mac (all Macs) has an energy-save setting which will automatically power down the video connection if the Mac detects you have not used the mouse or keyboard for a defined period. This might be the cause. Similarly many TVs also have an energy saver setting, in the case of the TV it might trigger if you have not changed channel for a number of hours, or it might have an IR sensor to try and detect the heat of a human body. If it does not detect a person 'watching' it, it would then turn off.
In your case the former sounds more likely. Open System Preferences, then click on Energy-Saver and check the settings.
Note: If the Mac does disable the video output due to this setting, it will almost certainly result in sound being switched back to the built-in speaker instead of going via the HDMI.

Sound Cuts Out During Playback-Sound Card/Audio Interface Necessary?-

I'm a voiceover artist with the following setup:
Sennheiser MKH 416 P48 U3 Microphone
Yamaha HS80M Reference Monitors
Mackie Onyx-i 1220 Mixer
Adobe Audition CS6
Dell Inspiron 1720 laptop (Intel Core2 Duo, CPU T5750 @ 2GHz, 32-bit)
Until recently, I could hear anything I recorded or pre-recorded items with no issues. However, now, as I listen to anything, the sound 'cuts out' (latency issues?). The meters on Audition will still be moving, but I'll get no sound from my monitors. I upgraded to Windows 7, hoping and thinking this would solve the issue, and that Audition would play nicely with Windows 7. This 'solution' seemed to have helped, but ultimately, it did not resolve my issue. At this point, I believe it's my sound card. My studio quality setup seems to be too much for my consumer grade sound card. Because my Mackie has an interface built into it, I did not believe that I needed an interface. However, I'm beginning to question that. So, that's part of my question. Is an audio interface necessary for me even though I have one built into my Mackie? If so, based on what I list for my system, does anyone have any recommendations for interfaces? If I do not need an interface, I'd appreciate any suggestions or ideas as to what's causing the sound to 'cut out' and how to resolve it. Any and all help, I thank you for it in advance!
E

Finally! I wrote a reply a few hours back but the fine folks at Adobe took the site down just before I hit send! Lucky I saved it elsewhere because the "recovered post" was only the first couple of paragraphs.
Anyhow, take 2.
Well, first off, your Mackie Onyx mixer has a firewire interface built in so it, in effect, becomes your sound card. The one in your computer isn't involved in the recording/playback process at all (at least not unless you're trying to do something like monitor via the computer card rather than the mixer). Therefore, buying another sound card/interface won't help at all.
Similarly, audio dropouts aren't a latency issue, at least not directly. Latency is the delay in the audio as it does the round trip via you sound interface (mixer) and computer. It's more of an issue for musicians trying to be beat accurate as they over dub tracks. However, the latency controls could be affecting your drop out problem. The latency control in Audition is effectively controlling the buffer size--and having a larger buffer (which increases latency) also gives you playback more protection against glitches when your computer gets busy doing something else. So...the first thing to try is increasing the latency/buffer size on the Edit/Preferences/Audio Hardware menu.
Another thing to check is that you're using the latest drivers from Mackie--check their site and download/install the latest if there are some available. If there's a choice, go for ASIO drivers rather than MME if there are some available.
Also, I mentioned your computer getting busy with other things--for serious sound work shut down everything else on your computer. Pay special attention to networking, wifi, and anti virus software, all of which are usualy prioritised to grab processor cycles over your sound work. Also make sure you shut down all system sounds.
Hope at least one of these suggestions works for you.

Voice Memo on iphone 5 has started to cut out at the 25.40 mark.

I have been using the voice memo function on the iphone without any issues with it recording to any length desired.
I use it to record interviews and podcasts. However, last night, without warning, it has decided to just stop recording at the 25.40 mark. At first I thought it was something that I did but then during a second interview, it cut out at exactly the same time again.
I have recently updated to IOS7 but have used the voice memo since without problems so I doubt its the update that has caused this.
Anyone know of any fixes?
Thanks
A

I have a 5c, and here is how I was able to trim a test recording:
1. Open the recording file in Voice Memos.
2. Tap "Edit" at the bottom. It's between the arrow-up symbol and trash can.
3. On the right side, near the bottom-right corner you'll see a blue box with a round blue dot at the top-left corner of it, and another one at the bottom-right. This is the Trim button. Tap it.
4. You should now see the recording with the "wavelengths", a vertical blue line (with a blue dot at top and bottom), and on each side a red line (also with red dot at top/bottom).
5. Touch the left red line and you'll notice you can touch/drag it to the beginning point of your desired portion of the recording.
6. Touch the right red line and touch/drag it for the recording's end point.
7. Hit the Play button to play just the trimmed portion, making sure it's what you want.
8. Once it's what you want, touch "Trim". Up pops "Trim Original" or "Save as New Recording".
On emailing it, go to the trimmed copy and click the arrow-up symbol, which will allow you to either message or email it.
EDIT: I found you can name your recording file to what you want by tapping the default name of it. A cursor will appear where then you can delete and retype a custom file name. Great for emailing so you recipients will know what it is by looking at it.

IPad cuts out and stutters on AirPlay music but iPhone does not?!

Hi folks, hope you can help with this problem, it's a little weird.
I bought an Apple TV a few days ago and have been enjoying streaming music from my apple devices onto the hifi system connected to the TV. It works great except for one particular use-case, which is really frustrating. Basically, I can do everything from the Apple TV, stream HD content, Netflix etc. all good. From my iPhone I can do everything over AirPlay, stream music from iTunes, from Spotify, stream high quality video from YouTube or off the device itself, all works perfectly.
On my iPad 2 however everything works EXCEPT streaming music, it's bizarre. I can stream a high def video from YouTube onto the iPad and AirPlay it over to the ATV and it never misses a beat. I can mirror my screen onto the TV and stream games like Real Racing HD with no issues or lag whatsoever. However when I try to stream music either from iTunes or Spotify from the iPad it stutters (cuts out) every 30 seconds or so, making the music intolerable.
The weirdest thing is that I can queue up the same track on my iPhone 4s and on the iPad 2, play it from the iPhone and it works perfectly, pause that, play from the iPad and it's a complete mess. Similarly, when music is stuttering and cutting out on the iPad, I can switch directly to the YouTube, or BBC iPlayer app and stream high def video over AirPlay with no sound or video problems, then switch back to the music - back come the cut outs. It's driving me mad, I want the iPad to be the device everyone uses to play music from, especially for parties, but at the moment I have to get my phone out every time.
So it's not a bandwidth problem or a wifi signal problem (because video over airplay is fine) and it only affects music and it only affects the iPad.
Any ideas?!?!
I should state that all the iOS devices have the latest apple software and I have already tried resetting the iPad, the ATV, my wifi router etc. etc.

"Sonos" your Airplay
Hi,
This observation elicited a Eureka moment. After months of problems with our airplay I had worked through almost every suggestion on the net to little or no avail.
As a result of this post I reconfigured one of our access points as a dedicated airplay network. Brilliant. We have now had 2 weeks of perfect airplay.
If you are reading this, you are probably fairly tech savvy. You therefore probably have an old router in the garage, shed or attic.
Get it out, dust it off and connect it to your network as an access point (Ethernet cable and a good internet search on your router). Set it up on an empty wireless channel as "*****airplay" or whatever suits you and connect the airplay clients (airport express, Apple TV, airplay speakers etc.) to that. Keep everything else on the original wireless network.
Interestingly, this is how Sonos have approached the wireless music solution.
This has worked brilliantly for us, I hope this helps others in a similar predicament.
Uncle Duck
Ps - This is a good work around, but , come on apple - it shouldn't need a degree in engineering
System
Variety of IOS devices- phones, ipods,iPads, MacBooks et al.
2 access point - main router ((virgin media Superhub (aka Netgear)), separate access point, Netgear WNDR4500
Laptops,desktop, printers etc
2 airport express, 1 apple tv
