Sound loss after close lid C870-17G

Hello,
I have a problem with my Toshiba C870-17G .
Almost every time when it goes in stand by or i close the lid and reopen it the sound will not work anymore , also usb ports are useless and if i try to shutdown or restart he remains stuck in Shuting Down forever.
I have on it W7 64 bit, all drivers are up to date .
There is anyone who knows what can i do to solve the problem?

That doesn't appear to be a US model, and this is the forums for Toshiba USA. You may want to contact Toshiba in your region. If it's a European model, you could check the Toshiba Europe forums.

Total Sound Loss After Update

My computer is completely silent after the most recent update (and was working immediately prior to it). I can't get sound out of Firefox, iTunes or even various games on my computer.
Not sure what specs I need to provide. If someone could let me know I'll be right on it.

Hi, after reviewing your screenshot, there are some Flash files for IE that are missing and also for FF.
Download the Uninstaller to your Desktop:
http://kb2.adobe.com/cps/141/tn_14157.html
Then download the Flash Player Installer for Internet Explorer to your Desktop:
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe
Then download the Flash Player Installer for Firefox to your Desktop:
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player.exe
After you have done that, be sure to follow the instructions on the Uninstaller. Use the Administrator account, disable any apps that use Flash, check the system tray for messenger service, etc. Set the Security via Internet Option to Medium for the Internet Zone.
Close all browsers, Run the Installer from the Desktop.When finished, Reboot(restart) your computer. When fully Rebooted, Reboot again( to clear old files) Then Run the Installer for IE and when finished, Run the Installer for Firefox.
When finished, Reboot the computer Once.
Test each browser here:

Check a few websites to see if Flash Player is now working properly with each browser.
Let me know, if you have any questions.
Thanks,

TV @nywhere Video OK, But sound loss after 40 sec (solved)

I Have a Problem With my TV @nywhere Master
The Video I OK at all time But after a 40 - 60 sec I am Loosing the sound,
Is there someone that can help me!!!???

I have come across many reports of this problem on the Internet, and all of them relate the solutions second and third hand. Has anybody seen an official knowledge base article from Microsoft or Symantec dealing with this issue? I have scanned both sites and no mention. Since this problem affects multiple TV Tuner cards, I would have expected, some official statement somewhere.
I have heard various reports that this is a Microsoft Messenger problem, an Norton Antivirus problem, a Norton Antivirus 2003 problem, a Norton Antivirus 2003 without a certain patch apllied problem, a Windows XP / Messenger / Antivirus problem, and it all depends on who is pointing fingers at who.
The explanation has been that whether Messenger is active or not, at some point Norton Antivirus starts messenger, and subsequently interprets the Tuner video stream as a virus, at the same time Messenger starts chewing all the CPU cycles, and audio takes a dive.
So what does that mean. If I have a high speed processor, I can compensate for the cycles and not experience the symptoms. Or maybe because I'm using Norton Antivirus 2004, it's not an issue. Or maybe I have a certain mysterious patch applied.
Would I be satisfied with either MS or Symantec suggesting turning off Messenger scanning, or turning off Messenger. No way! For those who use Messenger as a means of communication, that should not be considered a long term solution. At the same time, turning off Messenger virus scanning is not a reasonable long term solution. Rather than opening my PC to the risk of a virus, I might ditch the whole lot of them including the TV Tuner, if that was the case.
There is a responsibility for MS and Symantec to give a reasonable explanation / analysis of the problem and offer a long term solution, whether that is a fix or upgrade, whatever, something that their customer can use as a frame of reference to decide whether or not they want to go that route or ditch the lot. Pressure should be maintained on them to provide an official response to this problem.
I would start with Symantec. What? You can't tell the difference between a video data stream coming from a TV tuner and a virus. Give me a break. Your just too busy coming out with the next version of Norton Antivirus to fix your existing code. That's were the money is.
As a hot fix, turning off Norton Antivirus Messenger scanning is certainly the fastest and from reports, many have eliminated their symptoms this way. Eliminating Messenger is another story. You can't get rid of the sucker, without sacrificing your first born.
Again, does anyone have a link to first hand, from the horses mouth, information re this problem?

Sound loss after transferring video

i had all of my itunes music and videos on an ibook (G4 running OS 10.4.X) i just transferred all of it over to my new XP PC (and it took FOREVER.) now that I have my videos (purchased from the itunes store) on my pc, they will play - but with no audio! all my songs play fine, just the videos from the itunes store. any help would be appreciated!

I'm getting the same problems as well. I just bought a music video from iTunes (I'm using Windows XP) and the playback has no sound at all. I preview a music video from the iTunes store (30 second playback as usual) and there's no sound on those either. And of course, yes, the volume is turned up full blast.
I've tried to adjust settings as Apple has suggested (updating drivers, sound acceleration, etc) to no avail.
All my music plays fine, I can hear all of those!

15-r007TU-Display does not turn on when it automatically turns off after closing lid.

I just purchased hp 15-r007TU, Windows 8.1 x84. I'm facing a strange problem. After all initial setup, I put the laptop on to download and install all lates Windows 8.1 patches. The display is set to tuen off automaticaaly after 5 minutes. After 5 min it did turn off as set. But then I can not turn it back on. I pressed all (except power) keys, used touch pad, closed lid and opened but it stayed off. Laptop was on and running as I could see HDD lights flickering, I could hear system sounds on pressign mute/volume keys, also I could toggle WiFi with key. I then pressed power off key to turn Windows off normally. I did turn off. I again turned it on, I could see 'hp' logo with spinning wheel and then nothing. Display is off and I don't see start screen. I have to hard reset (press power button for more than 5 seconds) then display is normal. This happens every time the display turns itself off automatically after set time or I close the lid. Only after hard reset it works normally and I see the start menu.
The power settings I use are:
1. never put system to standby after preset time. (either on battery or AC power)
2. turn display off after 5 min. (both on battery or AC power)
3. when I close lid - do nothing. (both on battery or AC power)
4. when I press power button - shut down
I am using Windows 8.1 x64 with all latest patches installed. BIOS updated to lates available. All latest drivers installed.
I have not yet set password to the system to log in.
Help would be immensly appreciate. The device is still in warrenty if it needs to be replaced.

Hello K1200LT,
Welcome to the HP Forums!
I understand the computer will not sleep when you shut down the lid. You seem to have already done most of the troubleshooting I would've suggested.
To be honest, it is either a hardware or software-related issue. To determine this, I would like you to reinstall the operating system. It will clear up any software conflicts and allow you to start fresh.
First, please ensure you backup your files. Here is information on how to do this: Backing Up Your Files (Windows 8)
Once this is done, it is safe to reinstall the operating system. Performing an HP System Recovery (Windows 8)
If the same situation occurs, the computer likely has faulty hardware. At that point, please contact HP phone support. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide
Please let me know what happens. Thanks!

Sound problem after waking from sleep

When I wake my computer from sleep the external speakers to do not produce sound. This is not related to the 'red light' issue, no red light is shining and in the sound control panel 'internal speakers' is showing.
Interesting is that when I play with the alert sounds in the control panel I can hear them, but when I adjust the volume or try to get sound out of software (iTunes, Quicktime, etc.) I can not hear anything. Also, when the computer is waking from sleep if I quickly toggle the volume control I get one or two 'clicks' before it goes silent. I have repaired the permissions according to other posts but that did not help.
However, if I plug in earphones and take them out again the volume works. . .
any suggestions?

Hi everyone, after waking from sleep, the first sound that is played is accompanied by a hissing sound for the first couple seconds. It does not happen after that at all that I have noticed. It comes out of either the speakers or headphones.
Can anyone try this: (Esp. if you have a new MB Penryn update (most recent))
1) Close lid, put to sleep.
2) Wait 5-10 mins
3) Open lid, log in to iChat (with login sound on) or make some other sound play. Listen for a hissing or static sound within the first couple seconds of whatever you just played.
Thanks for any help!

Ipod to stereo sound loss

I've been searching a bit for this, but has anyone noticed some serious sound loss when connecting ipod to stereo or television and trying to play music? I've used it for TV and I didn't notice any major loss, but for music (using the standard headphone jack to white and red plug), it *****! If I turn the stereo up full ball it still lacks any punch (on a cd it would deafen me at this level). I want to buy a car stereo with an aux imput, but don't want to if it's not going to be loud. The ipod is new, so just want to know if this is normal?

I have used all of my 4 iPods as the main source for music connected to my living room stereo for years throug a docking station. (Not through the headphone output.)For my stereo i think the "latin" equalizer setting is closest to CD sound, but that varies. The sound is very close to CD sound and I do not lack any punch. I am using the same set up in the car and no problems there either. With the latest docing station the volume on the iPod has to be on full, but it automatically goes to full volume when docking.
By the way, I am using it with to stereos, One Denon and one Bose.

Trond

MacBook Pro shuts down when I close lid. How can I prevent it?

MacBook Pro shuts down when I close lid. How can I prevent it?

Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
Before Resetting the SMC
Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
Press Command + Option + Escape to force quit any application that is not responding.
Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
Resetting the SMC on portables with a battery you should not remove on your own
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. The power adapter indicator light may cycle off / on once.
Release all the keys and the power button at the same time.

Sound loss when moving Final Cut Pro X project to Quicktime.

This is a 33 minute football highlight film with music, live sound, radio calls, title screens and transitions. The video is HD and transfers flawlessly, but the sound stops after 90 secomds amd never returns. Not sure what I am doing wrong. Have made 35 player highlight videos without an issue, but they are about 10-12 minutes long each. So, I cut the video to 20 minites to trial a shorter version, and the sound cuts out at the same spot.
The video pkays back perfectly in Final Cut Pro X. Sent it to compressor directly, and aftr 17 hours, I got a "fail" message.
Can someone help me? This video is scheduled to be shown at a banquet on Friday night, and I can't show it if I can't get it to a bluray disc
Thanks

Last week I lost my audio shortly into the video.
It disappeared around the point of the first transition.
After deleting that transition and re-exporting the audio survived to what had been the second transition and so on.
After deleting all the transitions the audio was perfect.
I then put back the transitions and magically the video exported with no audio loss.
At the time someone else seemed to have the same problem so it may be some bug or glitch.
My solution was to delete all transitions and replace.

Yes, should be more than one, you just copied
the .iso to disk.
Not familiar with the program, but look for
burn ISO to disk or similar.
OR, uninstall that, and get ImgBurn HERE

The only thing I added was the /usr/sbin/pm-suspend.
When I run /usr/sbin/pm-suspend from a terminal, the suspend works fine, but when I try to use the close lid suspend I have trouble resuming. When I open the lid, the laptop starts making noises and lights up (as if it were to resume), but after a while it goes and suspends again.
Pushing the power button to try to resume (this is how I successfully resumed from the commandline suspend) causes the same behavior to happen, so I ended up just holding down the power button and rebooting.
I tried commenting the /usr/sbin/pm-suspend, and uncommented the default echo line. This caused "LID switched!" to be displayed 3 times on /dev/tty5; each one on the next line further to the right. I'm not sure if that is supposed to be normal behaviour.

Lock screen sounds muted after Siri use?

Hey!
I just discovered a weird thing that happens on the lock screen. I tested this on an iPhone 4S, iPod touch 5th gen and iPad 3rd gen, all giving the same results.
So here's the trick:
- Wake up device, then hold down home button to activate Siri
- Tap outside Siri area to close Siri
- Now, when you unlock your device, even with a passcode, the unlocking sounds won't sound. You can lock and unlock your device about 3-4 times after that and there will still be no sound. After a few goes, the sound suddenly returns.
It's just a little glitch I found. Help? Or tell Apple?

Yeah it does! Maybe you're not on iOS 6.1.3. I've also found it happens if you're typing, say in notes. The keyboard clicks don't sound, but eventually come back.
Are you speaking to Siri? Just activate it and tap out of it (not with home button) without saying anything.

Sound problems after iOS 4.2 upgrade

Experiencing very poor sound quality after iOS 4.2 upgrade. Bad eq, left channel dropping out, sounds like heavy reverb. Exists with iPod and pandora apps. Tried adjusting eq in settings. Any one else having problems?

Yep I just upgraded to new OS 4.2 on iPhone 4 and I get this static buzz sound when talking to people it's really annoying and sound quality is terrible. What happened? I went back to the shop and they said it's the upgrade and that there is an issue with it. They also said there is no point leaving the phone with them as they can't fix it that it's upto apple to release a patch for the problem. Can we get a fix for this soon before I damage my ears?
