Lion loses sound preferences after sleep

I have a 27" iMac 2011 quad core i7 3.4ghz running Lion 10.7.1. with a dual display setup (Apple 27" LED). I use a M-Audio Fast Track Pro USB sound interface with the latest drivers installed. After waking the computer from sleep, the Fast Track Pro is no longer functional unless I do a complete reboot.Any thoughts or fixes?

This only seems to affect one machine in our environment. However, its causing lots a havoc on that one users machine.

Lose Sound Preference after restart

After a restart my Mac Pro always reverts to the built in speaker. I have to go into the sound pref to change back to the external speakers. And Idea why?

I'd love an answer to this, I've had this problem for a while now

Pismo Sound Problems after Sleep in Tiger

Hi all. New to the forums and returning to Macs after years of cursing Bill Gates. Picked up a Powerbook Pismo from a friend and have been having some fun with it, but I have one problem I can't solve. I replaced the hard drive (saved the old one) and installed Tiger and 1GB of memory on the machine. All seemed well until I noticed that the sound would not work sometimes after sleeping. The sound will usually return with a reboot, but sometimes I'll have to actually turn the machine off, and clear the PRAM to get the sound to come back. Sometimes, the volume and screen controls will both not work at all (pop up doesn't even appear when the keys are pressed), sometimes it's just that the sound doesn't work, but everything looks right on the screen. I've also had the sound and screen buttons not work only to have pop ups suddenly appear and the adjustments happen several minutes after I pressed the keys. So far I've tried:
Clearing the PRAM
Checked the Pram Battery (ok)
Reinstalled Tiger (Still loses sound)
Downgraded to 10.3 (problem persists, and seems worse)
In system information on Tiger it says "there was an error when retrieving that information" when you click on the sound hardware.
The machine is a 500mhz Pismo with a 48gig drive and 1 gig of Memory (133mhz, would that cause this sort of problem?)
I have not tried going back to OS9 to see if the disappearing sound resolves as I don't currently have an OS9 disk.
This sure seems like a software problem, but I'm starting to wonder. I really like this machine and want to get it to work! Help!

Maxstang, welcome to Apple Discussions.
Did you repair permissions after you installed Tiger? Have you updated Tiger to 10.4.11?
Here's the Sound troubleshooting info in the Pismo Service Manual.
No sound from speaker(s)
1. Verify mute mode is not enabled (F6 on the keyboard).
2. Check the volume setting in the Sound control panel.
3. Verify no external speakers or headphones are plugged in.
4. Reset PRAM.
5. Make sure speaker cable is plugged into sound card.
6. Replace sound card.
7. Replace speakers (part of the top case).
8. Replace I/O logic board
Startup sound is heard, then no sound from speaker(s)
1. Remove sound preferences from System Folder, reset PRAM,
then restart.
2. Perform clean installation of system software.
Had the Pismo previously had OS X installed. There's a firmware update (Boot ROM version 4.1.8) that should be installed prior to installing OS X. However, when I got my Pismo with Tiger installed, the firmware was not updated (have since updated). However, I don't think this could be the cause of your problem, since I had no sound problems when the update was not installed.
The PC133 RAM (which runs at 100MHz) should not be the problem. I have PC133 RAM in my Pismo.
Since you replaced the HD, could you have disturbed the connection to the Sound Card. The Sound Card is located to the upper-right of the HD. Here's a helpful laptop site.

Sound off after Sleep

Windows 7 / E205 S1904 / Realtek HD Audio Manager/ After sleep about 33% of the time there is no sound. If the laptop is shut down, the sound usually comes back. Have reinstalled the driver from Toshiba site. Any suggestions?
Many thanks
Solved!
Go to Solution.

This appears to be completely a Realtek Software (Driver) problem, that Toshiba is not getting Realtek to fix even a year after the issue has been brought to public notice.
No permanent fix can really be made unless Toshiba compel Realtek to fix their driver software.
As for the work-around shown in an above post, after even further tweaking, it was noticed that the Microphone resetting usually does not need to be done.
So,to restate:
When putting the laptop to sleep and waking back up in a different power state than it went to sleep in, sounds stop working.
Example: Power plugged in, put laptop to sleep, power unplugged, wake up laptop, no sounds (and no microphone).
A reboot fixes this. This means it is a software (driver) problem & not a hardware problem.
As can be seen from the suggestion above, putting the laptop to sleep and starting up again in the same power mode that was in effect before the sound was lost, was one solution. However this is random, sometimes it works, more often it doesn't, and it is often inconvenient to put the laptop to sleep again when it is noticed sound is not working.
The quick fix, more concise (workaround) that seems to work most all the time is:
Unplug the power
Click the Start button, type in the "Search Program and files" box: Sounds
Select: Change system sounds
Select the: Playback :tab and right click on: Speakers (Realtek)
If : Show Disabled Devices : is unticked, Click on: Show Disabled Devices : to ensure it is selected (ticked)
Right Click again on: Speakers (Realtek)
If : Show Disconnected Devices : is unticked, Click on: Show Disconnected Devices : to ensure it is selected (ticked)
Right Click again on: Speakers (Realtek)
Click on: Disable
Right Click again on: Speakers (Realtek)
Click on: Enable
Plug the power cable back in
In case this does not work, use the procedure shown in the post further above where the microphone is also disabled and enabled.
If by chance you do this and you end up not being able to find your Speaker or Microphone icon in the Change sound card settings (Change System Sounds) dialog:
Click the Start button, type in the "Search Program and files" box: fix sound
Click on: Find and fix audio playback problems & go through the fix steps.
Repeat above step for Find and fix audio recording problems
This usually gets back an audio device that has been disabled and cannot be found in the "Change sound card settings" dialog. (It does not ever fix the "no sound" problem.)
Again, this is a TEMPORARILY FIX to this VERY IRRITATING LONG PENDING PROBLEM that has been neglected by Toshiba and Realtek.
Laptop: QOSMIO F60
O/S : Windows 7-64bit
All drivers and Windows O/S software up to date.
One ends up having no choice but to believe that the management of Toshiba does not really care all that much about its customers when they leave a known problem unfixed for years. That is sad, considering Toshiba's slogan is "Leading Innovation." A broken innovation is just that, broken, and a real leader does not leave its products broken.

T440s in Windows 7 Pro loses Wifi connection after sleep 7260AC

Hi guys,
I keep having issues waking up from sleep with my T440s. It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears. Only thing that fixes this is a reboot. I have removed "allow windows to turn this device off" under wireless settings.
Driver: 17.12.0.4
Dated: 28/08/2014
Software: Lenovo Access Connections
I do not use windows to connect to WIFI. I have dedicated profiles for each of my wifi networks at home and work.
This is a serious productivity killer.
Any help would be appreciated.
Thanks!
Solved!
Go to Solution.

This is a well-known issue with the AC card. Go take a look at the Intel forum.
You don't necessarily have to reboot to get the card back. Right click it in Device Manager and then disable/enable. It will come back online.
Some tips that have worked for many:
-DO enable the power saving setting. If I disable it on my T440p, the card is offline upon wakeup.
-Ditch ProSet and let Windows manage your wifi. Profiles might be convenient, but...
-Ad Hoc QoS - WMM enabled. Enable it on your router(s), too.
-Ht Mode - VHT
-U-APSD support - this one can go either way. Some leave it on and don't have an issue. Some have to disable it to have the card work after sleep. You have to play with it.
And, I really believe that the router/modem type can make a difference, too. Some just don't work right with this card no matter what you tweak on the card. With this card, I think an AC router/modem is the way to go.
Another thing is the driver itself. I had wake issues when I first got this ThinkPad about 10 months ago. Then, Intel released v 16.6 and that one fixed it. I've tried all of the 17s released since and all of them caused sporadic failures to wake. So, I have always rolled back to 16.6 and it always wakes.
Note this: If you use Lenovo Update, it won't create a restore point in Windows so your "Roll Back Driver" button might be greyed out in DM. Always manually create a restore point before you update a driver. And, if it's working, whatever it is, leave it alone. If the release notes don't address an issue you're having, skip it.
Driver updating is way oversold here and elsewhere. If you're determined to update anyway, at least don't be an early adopter. Let other peeps do it first and then come back here and see about the complaints! Also, you can download the driver at Intel in their Administrators sets of drivers. Bare drivers and no software overhead.
Good luck.

HP-HDX 18t w/ Vista 32 won't retain default sound source after sleeping

That about sums it up. It's a brand new HP HDX 18t laptop running Vista32. It's setup with HDMI to our flat-panel TV and we have a Turtle Beach Audio Advantage-Micro usb card so we can use the SPDIF digital audio passthrough to get the 5-1 dolby sound to the surround sound receiver. It all works as it should playing Blu-Ray DVDs as well as any other sound... no problem. If we completely shutdown and then turn it back on it's fine. But if we put it into sleep or hibernate mode instead, then it loses the default sound source setting we've chosen (SPDIF) and we have to manually reselect it. Same thing if we disconnect it entirely. But that makes some sense and we don't plan to do that a lot so it's not as big a deal.
Thanks for any insights.
I hope I've provided enough info.

I have the macbook pro 13 inch 2,66 Ghz april 2010 model.
I can't get my headphones to work in Windows 7, 64 bit(bootcamp). It seems like the cirrus logic CS 206 A (AB13)drivers are the problem.
I have installed the latest drivers, have set the headphones to standard audio device (I don't know how you call that option in english as my windows is dutch). I also disabled the macbook speakers, the digital audio device and nothing seems to work. I can play music through my macbook but can't play it through my headphones. In mac osx there is no problem at all doing this, the problem is only in windodws 7.
It's very annoying because I would like to play some games.
And yes I've installed the 64 bit drivers.

Mac mini server mid 2011 lion mouse pointer disappears after sleep

Hi,
I bought a mid 2011 mac mini server (quad core) running OSX Lion (10.7.2), and I use it with the magic trackpad. Sometimes (not every time) when I wake the computer from sleep (I let it sleep via the menu at night), the mouse pointer is not visible. I can use the trackpad, and move the mouse and click, only I cannot see where I click because the mouse pointer is not visible.
The batteries in the trackpad are OK.
When I plug in a USB mouse, I can move and click that too, but the mouse pointer is still invivible.
So it seems to be OSX related
The only thing that seems to help is to restart the system. After reboot the mouse is back as normal. Still this is very annoying as it makes sleep quite useless.
Anyone else suffering from this? Any solutions? Thanks.
Thanks,
Gino

I also have this issue intermittantly but fairly often.
But sometimes the cursor comes back but the screen stays black except where the cursor has moved across, revealing the screen, a bit like using the spraycan tool in MacPaint years ago.
And to top it off I have a problem with sleep making all the open apps try to quit, but one is always unable to, and it seems to lock everthing up until I wake up the mac, and then all the apps that were open do resume, but in the meantime any TV programs that should have recorded (by waking up mac to record) using my Elgato EyeTV have been missed ...

Magic Mouse loses scrolling ability after sleep

Hi,
I'm on a Mac Pro and got a new Magic Mouse which I really love. First I experienced the BT connectivity problems which many people have on their Mac Pro's which I tried to solve via the tiny Belkin external BT dongle offered in the Apple store.
Now the cursor runs smoothly and I don't have any connectivity problems, BUT after waking the computer from sleep mode, the Magic Mouse lost the scrolling ability. It clicks properly, but I can't scroll.
Everything is fine after restarting the computer.
Searching the net, I found that other users using that dongle don't have the same problem, so what's wrong here? Any ideas? I'm thankful for every hint!

Just want to give an update to my saga.
I have made many calls tonight only to wait to no avail. My last call took 35 min to get thru. After explaining my issues and findings to him in detail, he asked me to do the typical first defense steps. Shut down, and then remove the AC cord. Press the power button 10 sec to "fully discharge any residual power". Then restart. I am all too aware that when Mac goes into sleep (very similar to MS PC's suspend stages) there are different degree of sleep. If I wake it up too soon, the symptoms do not occur. While on the call, we did the sleep and resume twice. Each time I waited about 2 minutes, thinking it is enough for the system to go into deep sleep. In both tries, the mouse did not loss the scroll functions. Thinking the issue may be resolve - though I did have some misgiving about it, I let him go.
I later went back and do a better testing, by let the system stay longer in sleep before waking it. I waited may be 4 to 5 minutes. Sure enough both the mouse and KB failed - both reverted to what seems some sort of basic mode. I have the BT status pane open and so I can monitor what it does. Yes, given enough time eventually the OS reports lost of mouse connection. Then also reports lost of KB connection. Yet, in actuality both the KB and magic mouse still works in their respective basic functions.
It appears that the host BT controller after entering what I infer as deep sleep, it is unable to reconfigure both the KB and mouse to their designed full functions upon resume from sleep. It however, able to reconfigure them for basic functions so the user is not left dead in the water.
During my call, I ask the CSR what is the next step if the issues are not resolved. He mentioned deleting some sort of BT file somewhere.

Lose network connection after sleep on iMac but not MacBook

The subject line says it all:
I installed an Airport Express card on my old Rev A iMac when I got my new MacBook and an Airport Extreme Base Station.
The MacBook can go to sleep and, when I "wake" it up, it's ready to go.
After the iMac goes to sleep, its network connection is lost and I have to log back in.
Any way to fix this so the iMac stays logged in?

Haven't received a response but didn't want this hanging out there unresolved. Posted same question to Airport forum in hopes of a response there and marking this "answered."

ITunes loses Remote Speakers After sleep mode

Whenever I leave my PC unattended for an extended period of time iTunes can no longer find my remote speakers. The only solution is rebooting. The AE light remains green at all times but iTunes just can't connect.
I'm running Windows XP SP2 using AE and iTunes 5.0.1.4 and had this problem even with 4.7. My desktop has an intenet connection no problem so it is re-established when it is woken-up but iTunes does not. This happens whether I leave iTunes open or closed while I leave the PC unattended. Note that I'm not using AE for intenet connectivity. I'm using a d-ling hub/router and a wireless dlink PC card on my desktop. Any ideas?
Thanks,
-Peter

I also have the very same issue. My Airport Express is working as expected, but If I put my laptop to sleep and then wake it up again, and then I try to re-connect to the Airport Express, it is not connected. I have to either restart the laptop or Airport Express device to get it working again.
Very fustrating!

Satellite P100 - No sound after sleep mode or hibernation on Windows 7

Hello everybody,
I am desperately looking for a solution for my sound problem on my PC after having browsed many forums that were talking about the same issue but without effective solutions either.
I am posting this message as I am having a Toshiba P100-488 laptop running Windows 7 64 Bits (after having upgraded the CPU) and which is using a Conexant CX20549 sound chip.
Everything is working properly and so does the sound chip thanks to a Windows 7 64 Bits driver installed but I noticed that after coming back from the sleep mode or hibernation, then sound device is still recognized in the Device Manager and shown as active in the Control Panel and the task bar but unfortunately, no sound is coming out of the speakers.
I have tried several drivers (including those of Dell and HP on some sites) but still the same problem.
Also, I have tried to update the driver from Windows Update that suggested the Conexant SmartAudio HD2 but same behaviour.
Is there any of you who would have a solution for me or perhaps a relevant driver that could solve this annoying issue ?
Many thanks in advance.
Best Regards,
Fred

How does one silence mountain lion startup sound?

How does one silence mountain lion startup sound?

After asking this question many times and always getting the ususal fixes (that don't work in Mountain Lion) Psst, Startninja, turn down the sound when you shut down, yada yada yada. And the "why don't you just put it to sleep" comments :/ duh.. Sometime we want to shut it down!! Even Apple support has no idea how to do it. Here's is the fix and it is so simple it hurts.
Controlling the volume of the startup chime is easy to set in the System Preferences Sound panel, but you need to make two different settings if you have external speakers connected to your Mac. There is no need to use scripts or any other coding to make this adjustment.
There are both internal and external speaker output settings in the sound preference pane. In order to adjust (or turn off) the volume of your Mac's internal speakers, nothing must be plugged into the headphone jack. Keep in mind that this setting completely controls the volume of your internal Mac speakers, so if you mute the sound, and have no external speakers, you will get no sound at all from your Mac.
To adjust the volume on your Mac's internal speakers:
Unplug speakers or headphones from the headphone jack.
Go to System Prefs > Sound, then click on the Output tab.
You will then see Internal Speakers (Type built-in) highlighted in the window.
Adjust the output volume (which also controls the chime volume) in the slider at the bottom of the window. Remember if you mute it there will be no internal speaker sound.
To set the volume for your external speakers:
Plug in speakers or headphones to the headphone jack.
Go to System Prefs > Sound >, then click on the Output tab.
You will then see Headphones (Type built-in) highlighted in the window.
Adjust the output volume (which controls the chime volume in the external speakers) with the slider at the bottom of the window. Remember if you mute it there will be no external speaker sound.

Upgraded to lion now my wi-fi loses connection after sleep mode, it still shows as connected but does not go out to the internet. Please help

After I upgraded to lion I have been having constant issue with my wi-fi after sleep mode. I close the lid and when I reopen I open safari and cannot connect to the internet. Wi-fi is on and I am connected to my router, but it doesnt seem to be on the internet. Now how I resolve this issue is turn of the wi-fi and turning it back on, then i am back on the net. this is mos-def a bug i have never had that problem with snow leopard. Please assist or provide hot-fix

I have the same issue and have to cycle the wireless modem on the laptop. Doesn't matter if I'm on a preferred netowrk or no, or if I stay on the same network or move. I come out of sleep, I have to cycle the modem.
It's not life threatening, or anything, but it's a hassle. I didn't have the issue with Snow Leopard.

No sound after sleep

I have the latest MacBook Pro, 17 inch.
After putting the MacBook to sleep, I lose the sound to applications like iChat and Mail. I don't know how to get it back other than restarting the computer.
Suggestions anyone?

ok....
try resetting PRAM
if that does not work go about resetting PMU/SMC/SMU
check your settings in sound preference in system preference after your sleep thing....if that too doesn't work....man you should try out the archive install technique probably some system software has got corrupted .DO BACKUP YOUR DATA BEFORE ATTEMPTING ARCHIVE AND INSTALL EVENTHOUGH YOUR DATA REMAINS INTACT BUT THERE IS NO GUARANTEE .. Best Of Luck!!!!
