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.

Sound problems after upgrading to 7.1 and Pro

I have recently upgraded to Quicktime Pro and installed the 7.1 update, to create Podcasts at work. The only problem is now that non of my quicktimes will play sound. I have checked all volume control sections and mutes etc, its definitely a problem with the software. Also once a movie plays through, or if I try and use the play controls, other than initially pressing play, the player crashes and have to go to task manager to close it properly. The same occurs when you try and close the program.
I was going to uninstall and try again, but I was worried this might cause problems with the Quicktime Pro info.
Anyone else had these problems or have any advice.
pc amd 2.8 Windows 2000

I'm also having sound problems with Quicktime v7.1 Pro. If I play a .swf file in Quicktime, the video and audio play great. If I play an .avi file, the video plays but there is no sound. If I play a .mov created by Camtasia Studio using either the default compression or the H.264 compression format, the video plays but there is no sound. The graphic display indicates that the audio is present in all cases.
Is there an issue with this new version of Quicktime Pro v7.1?

No sound Windows 7, 64 bit running Bootcamp, MacBook Pro 64bit Snow Leopard

Been running Windows like this successfully for over a year. Now, suddenly, no sound. Tried re-installing Cirrus Logic etc, but to no avail. Possibly linked to some recent software updates? Tried to reverse, but didn't fix problem.
Have tried the various suggestions found via Google about compatability with Vista in Cirrus.
Any suggestions would be very welcome.

in bootcamp in osx one makes a driver cd which include apples drivers for all the hardware in the mac
and one then install that in windows to get everything working
do that rather then try to install drivers yourself

Microphone problem on Windows XP running on Macbook Pro

I just bought a Macbook Pro with a built-in Realtek HD audio card, and I have a problem using the microphone on the Windows side (I've installed via Bootcamp a Windows XP Home edition service pack 2). For some reason Windows doesn't recognise the microphone at all (although I have no problem with the loudspeakers). I tried downloading the new driver
Windows 2000, Windows XP/2003(32/64 bits) Driver only (Executable file) R1.89 2008/3/18 25421k
from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24& Level=4&Conn=3&DownTypeID=3&GetDown=false and ran the driver,
but it didn't help. Right now when I'm trying to detect the microphone using the Control Panel wizard an error message comes up, saying that there's an error code 0x80004005
what should I do?
Thanks a lot.

You should probably post your question in the Parallels forums:

Internal and external microphone doesnot working on HP probook 6550b

HP probook 6550b. Windows 7 Pro SP1 64bit.
Sound works without any problems but my microphone suddenly stops working today.
Usually i use my internal microphone.
I tried to plug in one of my external microphones to mic jack and it also doesnot working. I check my 2 external microphones on other PC and they both are woking properly.
1) Nothing new was installed today.
2) To fix this i tried to swich in sound properties default device but i dont see any green volume level behind mic images for both.
3) I removed all audio drivers
4) After PC was restarted windows installed default drivers but i still cannot record any sound. (Checked in skype and by green record level indicator in sound properties)
5) Also for default windows drivers i tried to switch my default microphone in 'sound' window settings and also plug in and out my external mics and without results.
Screen shot of windows after default windows drivers was installed:
What it can be?
Thanks.

First question, i would answer yes :
About this mac >Materiel > Audio (intégré) > audio haute définition Intel > microphone interne > connexion interne
Second question :
in system preference > microphone interne is black and not grey.
bars "sound test" near menu "entry level" does not move at all even if I shout...
Third question :
The power supply has been totaly replaced by a new one.
4rth :
Yes, no problem with speakers integrated or with the one of the headset...
On skype : i Hear but can not speak.
(i tested the headset on a PC, it works)

HP ProBook 4710s Sound Problems

I have a HP ProBook 4710s running Windows 7 Professional 64-bit (SP1). For the last month or so, I have had audio problems. When I am watching something on Windows Media Player, or YouTube, or anything on-line (including the sound through Skype), the sound is fine for awhile and then goes off for a few seconds. It then starts doing this on and off throughout whatever I am watching/listening to. I put in the headphones and the sound works perfectly there. But, what has now been happening is, once the headphones are in for awhile, the sound then starts coming out of the speakers as well as the headphones. New problem yesterday - I was having a Skype call, used my headphones to hear the person (worked okay), then the sound began coming out of the computer speakers and the mic stopped working!!! I could hear the person I was talking to but they could not hear me (this was after the sound starting coming out of the speakers)!!! It is all so weird and soooooo frustrating!!! I have tried all of the updates and nothing. What else can I do?!?!?! Thanks for any help you can give me.
btw - my audio is SoundMAX Integrated Digital HD audio

Hello aiappettennu,
Your ProBook is a Business model. Your issue would be best answered on the HP Enterprise Business Community Forum
Good luck!

PE 13 crashes due to incompatible video driver detected. Running on Win 7 SP1 with ATI 540v video card/driver. Deleting bad driver file in adobe program data does not fix the problem, it simply replaces the text file and crashes again. My video driver is just fine. Any help out there?

Your video card driver may be fine for something, but just not compatible with Premiere Elements 13/13.1.
For those with the display card error, the answers include
a. assure your video card/graphics card driver version is up to date according to the web site of the manufacturer of the card -
if necessary consider a driver roll back.
b. determine in Device Manager/Display Adapters if the computer is using 2 cards instead of 1
c. delete the BadDrivers.txt file
the rationale for that deletion is found in post 10 of the following older post...principle applies to 13 as well as 9.
Re: Premiere Elements 9 Tryout Serious Display Problem
Have you looked for computer ATI card settings that might be more compatible with Premiere Elements 13/13.1?
When is the program crashing - just opening a new project or rather crashing if editing a particular video format at the Timeline level?

MSI GT660 Sound Problem (Win 7)

Hey guys, i recently decided to reformat my MSI GT660, so obviously something i have not installed correctly has caused this problem. I'm just not sure what. The sound works, it's just as i'm playing music in the background every now and then, it'll sound distorted and messed up for a few seconds, then go back to normal.
It keeps doing this, and it's really annoying. I tried reinstalling the Realtek HD audio driver, but no luck. Any ideas?

Quote from: Bas on 12-October-11, 00:39:47
The sound is MP3? Internet?
Played with what player?
What do you do in the foreground?
100% CPU load can cause such too.
Your information is waaaaay to little to even start guessing.
Hmm yeah, guess i wasn't really thinking. Right, it's played using Spotify, i just tested with Winamp though and the same problem is there. So it's all kinds of sounds really. I don't think it's 100% CPU load cause i checked the core history and none hit 100%, also i'm only browsing the internet when this happens. So to answer the question of what i'm doing, not much really just opening new windows etc.
It never used to do this before i reformatted it, and it's only just started now. I don't think i noticed any sound problems when i was playing a game earlier though... i'll have to check that one out.

PROBOOK 6540B SOUND PROBLEM

No sound from the computer's speakers. all drivers are installed. Sound comes from the headphones, but no sound from the speakers. When I delete the IDT audio driver sound coming from the speakers but no sound from headphones

Hi. Yes. I also tried all tricks with model etc. and nothing. Now I have installed oss and have some progress. I have sound on pcm2 when I run osstest, no sound on pcm1 (but it looks in test like it plays something) and input/output errors from pcm3 to pcm7. I have oss output in multimedia in kde and when I run test I can see moving strips or something (I dont know the word for it ) in ossxmix but I hear nothing. I I tried all configurations in ossxmix and nothing.

ProBook 6550b Recovery DVD Set

I have just purchased a used ProBook 6550b, Product WD704ET#ABU from an e-Bay source. The unit came without HDD, Battery, RAM or charger, all of which I have ordered. The Microsoft COA label says that the original System was Windows 7 Pro OA 64 bit.
I have a Desktop PC which is already running Win 7 Pro 32 bit and still have the 64 bit version DVD. Can I use this to do a clean install on the new HDD when I get it, but use the COA Product Key when authorising the PC with Microsoft?
Since the Hardware will have changed from the original authorisation, (HDD and RAM increased in size), will I have to purchase a set of HP Recovery DVD's in order to restore the system?
If the latter is the case, what do I order and where do I order it from?
Any help will be gratefully accepted.

Hi,
What is the insallation DVD, is it also a HP OEM version ? If not this may not work but as the HDD is a brand new one, you can always try, worse case you lost around 45mins of your time. More RAM and new HDD should be ok. You can order from the following link:

Hello!
I have problem using Toshiba Software Installer for Win 7 on Satellite L750-1MT (PSK30E-02T002B3) with no OS preinstalled.
I do the following:
1. Install Windows 7 x64, SP1.
2. Install LAN driver (device was not recognized by Windows 6) (downloaded from [http://se.computers.toshiba-europe.com/innovation/jsp/supportMyProduct.do?service=SE&LNG=26&userAction=S MP_RESULTS_PAGE&partNumber=PSK30E-02T002B3&serialNumber=&USER_ACTION=Serial%20number])
3. Install all Windows Updates from Microsoft
4. Run Toshiba Software Installer for Win 7 - it installs a couple of drivers and then asks to reboot.
Here is the log file for the first try (win7update.log):

Hi,
Try the following.
Download the IDT Audio installer on the link below and save it to your Downloads folder.
ftp://ftp.hp.com/pub/softpaq/sp59001-59500/sp59291.exe
When done, open windows Control Panel, open Device Manager and open up Sound, Video and Game Controllers. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow thisand then proceed with the uninstall.
When complete, shut down the notebook, unplug the AC Adapter and then remove the battery. Hold down the Power button for 30 seconds. Re-insert the battery and plug in the AC Adapter.
Start the notebook and let Windows fully load - it will automatically load an audio driver, but just let this complete. Then open your Downloads folder, right click on the IDT installer and select 'Run as Administrator' to start the installation. When this has completed, right click the speaker icon in the Taskbar and select Playback Devices. Left click 'Speakers and Headphones' once to highlight it and then click the Set Default button - check if you now have audio.
Regards,
DP-K
