T520 loses sound after sleep

Hello,
I recently bought a T520 and am having issues with the sound. When the computer goes into sleep, then is resumed I lose output from the sound card. When I check the sound properties in the control panel everything looks OK, but no sound is heard through the speakers. The volume is at around half.
Soundcard: Conexant 20672 SmartAudio HD
Soundcard drivers version: 8.32.18.0
This is the latest version according to Lenovo System Update.
Disabling and enabling the device in Device Manager doesn't help.
Any ideas?
Solved!

@benc,
Latest driver for the T520 should be 8.32.23.0.
Try updating it and see if it helps.

I lose sound after about 20 seconds on video in CS6. It plays fine outside of CS6. Why?

I lose sound after about 20 seconds on video in CS6. It plays fine outside of CS6. Why?

And what does "CS6" refer to exactly? In any case, ask in the product forum of whatever program you are referring to and for the life of it provide more info like system specs, file types used and so on.... "This doesn't work" posts are useless.

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

This appears to be completely a Realtek Software (Driver) problem, that has not been fixed well over a year after the issue has been brought to public ([Toshiba Forum|http://forums.toshiba.com/t5/Audio-Sound/Sound-off-after-Sleep/td-p/173036|Toshiba Forum]) notice.
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 points to a software (driver) problem & not a hardware problem.
Putting the laptop to sleep and starting up again in the same power mode that was in effect before the sound was lost is one way to avoid this happening. However this appears 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, (workaround) that seems to work most all of the time {color:#0000FF}(_[m-267849#267849]_){color}in another post on this forum.
This is a *TEMPORARILY FIX* to this {color:#ff0000}*VERY IRRITATING LONG PENDING PROBLEM*{color} that has been {color:#ff0000}*neglected*{color} by Toshiba and Realtek.
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.

Mail sound after sleep

Hi
Sometimes after sleeping my 5K iMac stops playing sounds from mail (all other sounds work fine).
If you go into the mail settings and change the sound it doesn't make any noise. Quitting mail and relauching fixes the issue.
Anyone else the same?

same here
I had power nap on.
I turned off power nap.
Now after it goes to sleep, it will wake up and still make the sent sound.
good luck

Why does my imac lose wireless after sleep?

I have a brand new imac core5 that loses it's wireless connection after sleeping. OS X 10.7.2
Any help for this? Sometimes can turn wireless off and back on to fix, but sometimes have to restart the computer.

Apple just posted this patch:
http://support.apple.com/kb/DL1501
This DOES fix the problem.

Mac mail makes no sound after sleeping

Why does Mac Mail stops making the new mail alert sound after falling asleep? How can I solve this?
I have to close mail, wait a few seconds, then reopen to restore the sound. Very annoying.

Very loud fan sound after sleep when Ram is upgraded.

Recently I have upgrade the Ram memory from 1Gb to 5Gb with (2x2GB) FB-DIMM DDR2 667MHz from Ondamatica. Memory works perfectly, hardware tests were OK and i didn't notice any issue except one: after sleep, fans start to spin faster and faster (seems like a vacuum) to what I supose Is the fastest speed they support, during arround a minute or 45 seconds. That generates an intense noise but happens only when awake afer sleep, not when restarting.
I've done almost everything: reset pvram, reset SMC, change memory slots... And the issue only stops when I remove the new two Ram modules.
I've read about it in some forums, but no one solved it. ¿Any suggestion before I return the Ram to the store?. Could be a software problem?.

It will or can happen but you can reduce it somewhat maybe using SmcFanControl (2.1.3.1 - wwww.macupdate.com ) to keep the fans above default by 200 rpm. And run Hardware Monitor to monitor temps as well. They may be running much warmer than they could/should/ought to.
1GB and your system was on starvation express! ouch. 4GB is more of a normal minimum even. 4 x 1GB is nice balanced setup. 2GB DIMMs might be warmer, run 70C perhaps. And they use about 15W each.

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.

TS3367 I lose sound after several minutes

I continue to lose sound during a face time conversation 3-5 minutes into the conversation. The other end can hear me fine, but I can no longer hear them. I usually hang up and call again and it's fine for awhile longer. I've called into Apple several times and so far the advisors have never heard of this problem. So far I can duplicate it when using my earbuds or without. I use my iPhone4S and my sister users her iMAC. Apple had me reset and test. Of course the next call I made for 6 minutes was fine. I made a call to the same person later in the day and could no longer hear 2 minutes into the conversation.

If you can duplicate this issue 100%, then I would advise to bring to an Apple store to show them so it gets documented in the system. It is a very odd issue because I have never seen anything like that.
Your not receiving a call or switching to apps during the facetime conversation?

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!!!!

Multiple airport express plug-ins with i-tunes- lose sound after 4 songs

I have 3 airport express units, a MacBook and 24" IMAC G5 and my music library on a LaCie external hard drive. I have all the latest updates for the airport software on my computers. Now for the problem
I want to play my i-tunes library, it is over 500G in multiple locations throughout my house. I play from my I-Mac. All airport express connects to my linksys router network. I get inconsistent results when I play my music to multiple locations. After several songs play I have to go back to my computer and repress the speakers to play even though my imac shows the music playing I get no sound.
This could be because of a simple setting on my i-mac, I hope so. My energy savings for my screen goes off with inactivity after 15minutes. I changed that to an hour yesterday with no avail. I would love to have my music playing throughout my house on a consistent basis. Please help.

I forgot to also mention that I use the "interference robustness" feature on my IMAC. I have tried it both ways with the same unhappy results.

Exporting .avi to .mov using h264 loses sound after a few seconds

Here's a weird one. I am editing some movie clips, and when I do an export to .mov format using h264 compression, the audio drops out after a 8-10 seconds.
At first I thought it was happening after an edit jump, but nope -- it just cuts out for some reason. I also cannot export to MP4 format without losing the audio completely (shows as MPEG Layer 3 audio in the properties window of the original). When I look at the Properties for the exported movie, I can see the audio length is not the full length of the video.
I have edited clips like this before in QuickTime with no issues, not sure what is going on. I tested on MPEG Streamclip and I can export to either format with no sound issues.

Hello George,
Sorry I can't help you with your problem. But it is TOO much of a coincidence that YOU do everyday (try to, lately!) what I am trying for the first time-- converting .avi files to .mov files. I just got a cheap movie cam and it saves files to avi format. I am able to transfer them successfully to my Mac, but cannot find a third party avi converter. If you can help please email me: [email protected]
thank you for your time and I hope SOMEONE out there will help YOU!

Mail won't make new-mail or sent-mail sounds after sleep

I've had this issue for the last 6 months, probably ever since 10.7.3 update in May.
Mail stops making the usual noises after going to sleep one or two times. The weird thing is that it will store all the unplayed noises in a buffer and then suddenly decide to play a few months worth of sent-mail and incoming-mail noises at a rate of one per second for several minutes upon waking up. Apple was no help.
Restarting seems to solve the problem until the next sleep cycle when it starts up again. I did a full restore twice and it made no difference
Apple's mail specialist hadn't ever heard of this issue before when I called in September. It's not a game stopper but I worry it might be a hardware issue that I'd like to have fixed before my warrentee runs out.

I've never seen anything like this reported before. Verify/repair your disk (not just permissions), as described here:
The Repair functions of Disk Utility: what's it all about?
If the problem persists, proceed as follows:
1. Open /Applications/Utilities/Console.
2. From the File menu, choose either Open Console Log, or Open System Log, or both, so that the Console application displays the contents of both system.log and console.log.
3. Try to reproduce the problem, and look at the bottom of the Console windows for messages that could have been written there as a result. Do you see anything that could provide a clue as to what's going on?
Now, try this:
1. Go to Apple Menu > System Preferences > Accounts, and create a new user account for testing purposes.
2. Either log out of your main user account or just quit Mail so that it does not interfere with the other user account.
3. Log in as the newly created user and set up Mail anew there. Does the problem happen there as well?

Apple TV loses connection after sleeping

My Apple TV had virtually no problems with a connection when being used, but has this curious quirk of losing it's connection after an extended sleep period. It seems as if it sleeps for more than 8 hours, it will no longer be connected to my network. Viewing the settings for the Apple TV, it shows that my connection should be working and has full strength, but doing a test results in nothing happening. My options are restart or drop connection and input my network password again. This gets really annnoying, because almost everytime I want to use it, I have to do either of those things first. Are there any internet settings I can chnage so that this stops happening?

Actually same goes for the iPhone after charging it when I sleep, next day, have to turn wifi on and off to get the connection to work properly.

Lose bluetooth after sleeping

Every time my MBP has to sleep I lose the bluetooth. When it wakes up, I am forced to open the lid and use the touchpad to shut off the bluetooth, then back on.
This has a 23 inch LCD connected full-time to DVI. Is this a common bug?

One thing that can work, try this, please ignore the exact symptoms and connection and Hardware types, it's worked for many others than the stated...
