M645 - s4050 sound problem?

it occurs to me that does any one currently have a problem with the m645 sound device? for instance in my laptop, it would at random increase the sound and constantly increase it for no reason and i can't mute it down or rather it would decrease the volume at a fast alarming rate and won't let me control it any one can tell me a fix or repair to it?

I have the same problem with my 2 month old M645-s4050 among other problems. I got the cooling system warning when the computer was running in the "eco-utility" mode and on battery power. My mute touch button stopped working. Also, when I run the computer on battery power, I get this really harsh system beep when the battery life diminishes to 10%. I tried everything to turn off this beep to no avail. When I went to the Toshiba Health Monitor utility, it showed a 90% of max fan speed and "fair" battery life. After trying to troubleshoot the problems over the phone with Toshiba customer service and not getting anywhere, they suggested I ship the computer in for service. They said they would fix the cooling system problem and mute button, but I would have to put in a request for a new battery once it got back from the service center (all covered under the warranty). I sent the computer in 3 days ago. They send email updates on the progress of the repair, and they are still in the process of fixing it. I will let you know what they find is the problem...hopefully. Here is a link to the blog for the issues I have experienced: Brand new Toshiba M645-s4050 battery and fan problems

Satellite M645-S4050 Techinical Problems

I currently bought this laptop 3 months ago within the late august and it was working fine. After the first week having it, the laptop was having problems. For instance, the backlit buttons on the laptop (the lit icons above the function numbers) would constantly turn on/off by itself. In that result it would make my volume for the laptop control go constantly up and down. Also it would disable my internet connection when i am currently doing nothing. Another problem that is occuring is constant movement. If i currently move my laptop just a tad bit, it would freeze or slow down what i am currently doing. Would some one please tell me what will help me fix these problems I am currently having. Mostly likely there are other people who probally have the same problem as i am having right now.

Right up to the mention about simple movements locking the machine, I would consider this might be a software problem. The only other thing I can think of that *might* possibly cause this is the "Hard Drive Protection" utility. Have you tried temporarily disabling this? Actually, try booting the machine in "safe mode" and see if you can still reproduce the locking. If you still get the same result, try booting to the HDD recovery partition by holding down the "0"-key and then see if you can reproduce the locking. This should eliminate any software related issues. If yous see the problem even after booting to the HDD recovery partition, I would strongly believe this is hardware related and will require a visit to the repair depot.

Skipping problems on Satellite M645-S4050

Hello,
I have a Satellite M645-S4050 and I I bought it in July of this year.
I've noticed that if there is something playing on my computer, whether music (on itunes) or a video, and the laptop is moved (even if the desk it's sitting on is bumped slightly or I put my elbow down too hard) it skips like the old walkmen used to. Once or twice it has even gotten stuck like a phonograph. I brought it in to where I bought it and the guy said that it was the way the new software was made in a lot of the faster hard drives and the only way to do anything would be to buy a more compact hard drive and transfer everything.
But I notice it getting worse and I am disinclined to believe him because the point of a laptop is to have a modile computer. I cannot even listen to music or play minesweeper in the car because the skipping is so bad it messes with how the computer functions. Is this true and is there anything I can do to fix it?
Thanks,
na

Hi na,
I agree with as*** and if you have HDD protection utility, you should be able to reproduce this issue: Just move your notebook a little bit. You should notice this skipping problem again.
As far as I know in options of this tool, you can change the sensitivity. Choose a lower value, maybe it helps! :)

Touch sensitive multimedia buttons don't work ! (Toshiba Satellite M645-S4050)

I've Toshiba Satellite M645-S4050. My multimedia touch buttons don't work except Vol+ and Vol-. All of them are making sounds when I touched but no action! 1) I uninstalled Toshiba Value Added Package (TVAP), 2) rebooted the machine, 3) installed TVAP then 4) rebooted again. But nothing's changed. 5) I reinstalled all Toshiba Utilities includes Assist and Flash Cards but same result. Also 6) I unplugged the battery and AC adapter because of static energy issue possibility and 7) choosed the default settings from the BIOS menu. Still same ! What am I supposed to do ?

If it's under warranty, I'd send it back to Toshiba and have them fix it right this time. It took 2 repairs for the Depot to fix my problem, by replacing the mother-board.
Call customer relations and try to get it sent to Toshiba "VIP" Tri-Star repair facility in Garden Grove CA 92843, they repair it when their regular service tech's can't get it right the first, or second time.
Fix it now, or it will be a hassle for you as long as you own it.

What sound problem - no sound on anything, no sound on some apps ?
Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Desperately need some help!! iTunes/Quicktime/iChat/Sound problems....

So, yesterday, I was online, on google video, and when I pressed play on the video, there was no sound, but the video worked...the same was true on every video site i checked. My computer volume was at max, and I even tested the speakers to make sure they were on, and they indeed were.
I thought that was odd...but then the problems really started.....
After that, I clicked on my iChat icon. It bounced once, and did not open. The same thing happened when I clicked on iTunes. 1 bounce, and then nothing. I checked to make sure all of my iTunes mp3 files were on my computer....they indeed are all still here, bit nothing I can do opens iTunes. I've run disc utilities, and disc repair...according to that, everything is peachy-keen on my computer.....but iChat and iTunes STILL will not open, and there is still no sound on anything.
Now, i'm leaning towards the archive and install option....or even just backing up what I want to save, wiping the drive, and starting from scratch.....but i'd really like to not have that happen.
(and, as a side question, if all I want to save are images, several documents, and many mp3 files, would everything be okay if I just backed them up on an external drive, and then loaded them back on to my computer after reinstalling OS X?)
Sorry about the length of this, but I am at my wit's end, and I have no idea what to do.

by third-party, do you mean things I installed that are not manufactured by mac? If that is the case, I have microsoft office, Smart Music, Flip4mac, and Senuti.
I got rid of Flip4Mac to see if that affected my sound problems, but it did not. So, as of now, my problem remains the same...

Did you download and install the Windows Support software? First step in Bootcamp Assistant is to download the support software. Then did you install the support software from within Windows?

Sound problems on ProBook 6550b, running on Win 7 Pro x32bit..

I have been getting very similar sound problems on my notebook as posted by most: internal speakers work on original Audio HD drivers, but there is no sound when I connect external speakers or headphones. I up-graded the audio drivers to IDT HD Audio and I get sound coming from external speakers or headphones, but nothing from internal speakers.
I have tried everything from reporting the problem on public forums, live help, and done this or that, but nothing changes. It's so very clear to me that it has to do with audio drivers, which don't seem to work appropriately to cover all aspects of sound output.
I also, often, get this loud, weird, irritating noise and a frozen PC when I am playing music with the notebook, while on the internet. The best I do is not to do both at the same time. I have seen similar problems on blogs, but tangible solutions are NOT offered!!!! Please help...

Audio Switching coudl be due to several reason. if you have tried latest audio drivers and latest Video drivers from hp.com, i suggest you to get audio board replaced for your computer.
Hope it helps.

Any resolution to the sound problem?

I have been having the same sound problem with my Mid 2010 Mac Pro tower ever since I got it. I have been in touch with Apple and have been told that they are familiar with the problem, but that they are still working on a fix. The problem is that I have external speakers, and every time I shut down and then start up again, I have to go to preferences and physically change the sound output to go to the speakers. I have also been tole that the Mac is supposed to sense the external speakers and go directly to them.
Is there anybody else out there with this problem, and has been able to resolve it?
Thank you.

I have a 2010 Mac Pro and use the stereo line out jack in the back of my machine for my speakers with no problem. I don't recall any problems setting it up. But check the Audio MIDI Setup (in your utilities folder) to see if you can set it from there (should be able to). Not sure why the preference wouldn't stick. And I don't believe there is automatic detection of an attached sound output device where the sound preference switches to that (unless maybe the front jack which I never use).

Sound Problems on iPad: how to fix, easy [video]

Hi dear iPad user,
Most people will, eventually, have sound problems: the cause can be complex as a 'miss-behaved' app that messes the sound engine or as simple as the iPad being forgotten on Mute/Volume Down.
I used to help family and friends to fix their iPads' sound problems by sending them 'text' instruction steps... lots of times they ended up calling me on the phone...
So I made a video (short: 1m40s):
https://www.youtube.com/watch?v=FjBP-Ncj_fE
It shows:
how to unmute the sound (even if the side-switch locks the rotation of the screen)
how to put volume up
how to close all the apps (in the case there is an App messing with the sound system)
how to reboot the iPad (ultimatelly fixes hard cases of messed sound system)
What it won't fix: if you have a hardware problem...
If you do all the steps and you get NO SOUND AT ALL, please, try also checking if you car listen sounds using a HEADPHONE (you know are working conditions). If you can listen to sounds in the headphone but no sound at all in the iPad's built in speaker, well, there might be a hardware problem and you should look for help on an Apple Retail Store or other official technical support available at your location.
Hope this helps!
Everson.

UPDATE: fixing iPad Sound after iOS 7
http://youtu.be/SDf1LDcE95Q
(1min 36sec)
It covers the basics:
checking side-switch / mute / "Control Center"
volume all up
...and also the worst cases:
closing all apps (for rare cases when a single app might render the sound system instable)
rebooting the iPad
So, don't get desparete: try the things in the video.
There are people who reported having forgotten an audio-bluetooth connection activated with a turned-off sound-system or speakers... or forgot Air-Play turned on... so be sure you disengage bluetooth and/or airplay.
On the 'hardware side', dirty dock connector (30 pin) can make the iPad 'think' it is connected to external audio - if so, cleaning it with a dry toothbrush can fix. Also, moisture in the headphones connector can make the iPad switch to 'headphones' even without headphones connected, making it silent: check if you can hear things with headphones plugged in - if so, try gently inserting and removing headphones a few times and check if you get sound back to iPad's speakers alone.
Good luck to everybody! Audio problems are quite common - fontunately they are easy to fix.

Hi Nick,
Sorry for the long delay I only just noticed your post. Easily done if you post in the middle of another thread.
To diagnose your sound problem the best approach is to systematically check (and isolate) each possible problem area until the culprit is found. For sound problems follow the sequence :-
1. Check Hardware. If you have a manual control check that it is turned fully on (this may be a wheel or knob somewhere on your notebook). There is no point carrying on if this is turned down/off.
2. Check Software. This is where the fun begins.
2.1 Check the sound properties (available from Control Panel) and make sure that the MUTE box is not ticked.
2.2 Check the individual volume levels shown on the sound properties box. Set them all to maximum.
2.3 Select Device Manager (from Control Panel) and check the entry for Sound/audio devices. Select your sound device and click the 'troubleshooting' option. Follow the on-screen checks.
2.4 If you still have no sound deinstall the sound device (from ADD/REMOVE hardware) and reboot. The system should detect the sound device and re-install it)
2.5 Finally download and reinstall the correct device drivers for your sound devive from the Toshiba web-site.
2.6 If you still have no sound after all of the above then I would recommend a complete re-install of your system from the Toshiba Recovery CDs. and if that does not correct the problem then you will need to take it to a Service Agent for them to sort it out.

USB Sound Problem

I'm having a problem with my Bose USB sound system that has just recently developed. The system is plugged directly into the back of my Mac Pro desktop so it's not going through any hubs or secondary systems. When I first start my computer the sound works just fine. But after about 10 to 15 minutes of use the sound stops completely - as if the sounds have been turned off. If I boot into Windows 7 using Boot Camp, the sound system there works just fine with no problems at all, so I do not believe this issue is hardware related but is something associated with OS X.
This all started recently after installing Tinker Tool and then realizing that their latest version is not compatible with Snow Leopard. I followed their directions and told Tinker Tool to restore the previous settings and then I removed it from my system. Now, I'm having this USB sound problem. I think it's highly probable to be the cause of my problem.
Is there anyway to reinstall the USB drivers in OS X without reinstalling the entire OS? Or, is there something else I can try to restore the USB function to Snow Leopard? Many thanks for any tips or suggestions.

They are plug and play.
I did try unplugging all of the USB devices and then powered off the computer and unplugged it for about 5 minutes as I heard that that sometimes solves USB problems. However, upon reconnecting the problem returned. All other USB devices seem to be working normally - it's only the Bose sound system. I tried plugging it into a different USB port in the back of the computer but the problem continued after about 10 minutes. Therefore, I am convinced this is not hardware related.
At this point I am thinking I need to reinstall OS X Snow Leopard to undo whatever Tinker Tool damaged. Is it possible to just replace the USB drivers in OS X without reinstalling everything?

A30 sound problem

have tried all drivers from toshiba web sites, uk, canada, europe etc but cannot get sound to work on my satellite a30, model no PSA33E 7C3F3 EN, fresh install of xp had 4 drivers missing, ati video, smbus, modem and sound, only drivers from canada site worked for video smbus and modem, xp states sound working properly but no sound from speakers or headphone socket and have checked all volume levels (on full nothing muted), any ideas ???

Hi,
Just to inform you that my problem was solved by itself :)
I've reformatted my laptop and installed the original XP Pro SP2 again by following the instructions.
Sound problem was solved automatically, no chipset utility installation required..
The sound problem was probably caused due to missing Microsoft KB835221 update for SP1, and KB888111 for SP2, which then was solved with the original latest XP..
Rgrds..
