Sound distorsion on DV6870ee with windows 7 professional

Hello fellow HP owners and staff,
I have had an HP dv6870ee laptop for a year now, and I've been very pleased with it. I'm a member of the IEEE community and in consequence, we get free software from Microsoft. So I installed Windows 7 professional RTM version on the lappy.
The original OS was windows vista with all the hp goodies that come installed (as a side note I gotta say: HP, YOU DO A TERRIBLE JOB WITH VISTA'S STARTUP PROGRAMS considering the extremely loooong startup time) and everything was really fine. Sound was very clear and hardly distorted. The speakers are Altec Lansing made.
Now when I installed windows 7 the sound from the speakers became very distorted even with audio tracks that didn't distort before. Please note that I'm using 320 kbps tracks ripped straight from original albums. I'm extremely sure that the Realtek Audio manager's settings are exactly the same ones in vista (I don't play with sound enhancements I leave them all off, because those speakers sounded wonderful on vista and didn't need any enhancement).
Has somebody experienced such a problem? And do you know what might be the solution for it?
Thanks in advance !
Ciao

Not a solution yet, but received the following from one of the tech people I've been e-mailing back & forth with.
"I'm sorry that you have been unable to submit your podcast. The podcast submission form is currently offline. When trying to submit the podcast you will receive this message "We are Currently Experienced Technical Difficulties". Once the issue has been resolved, I would be glad to inform you.
Apple is currently working toward a resolution for the issue you have reported. You will receive an email after the matter has been investigated and further information is available."
Who knows, maybe the problem isn't with my feed after all.

I bought an iPad 3 yesterday; this is an upgrade from the original iPad. I was told that migrating the data would be simple. My desktop is a PC with Windows 7 Professional. I can't find a way to back up my old iPad so I can restore the data to the new

I bought an update to the original iPad an iPad 3. In was told that migrating the data from my old iPad to the new will be a snap. Alas, it isn't. My desktop is a new high end PC that came preloaded with Windows 7 Professional and I have had nothing but problems. My earlier computer was XP and everything, including my Apple interface, in particular iTunes, worked without problems. When I was trying to back up my data from the old iPad to my desktop, the only thing it would do is synchronize, then got an error message to download the latest iTunes, which I did but it still did not work. I have a lot of music both purchased through iTunes and a lot of others which were CDs that were copied to the desktop. I also have a lot of books through Kindle and other books in iBooks and audio books from other sources, plus two iPods I want to sync. I need some advise on where I find the back up feature in iTunes so I can copy all the data on from my old iPad. Your help would be most appreciated. Thank you.

In technical support, sometimes you have to make educated guesses. I'm sorry that you were offended.
iTunes does prompt when it is going to erase a device, and the message is clear.
She said in her message that she was able to successfully sync the old ipad. This indicated to me that itunes wiping the data was not an issue, because either it had been setup at the apple store (in which case it doesn't actually wipe the ipad despite saying it will*) (*based on a single case I saw), or because the itunes media folder was migrated.
Furthermore, my solution was to tell her how to backup her ipad (by either doing it manually, or as a last resort, by deleting the corrupt backup -- that she couldn't access anyway.)
I got that last part of the instructions from the "Taking Control of your iphone" book which I found samples of when I did a google search for "corrupted backup itunes".
She marked this as a solution, so it worked for her.

I have two pc, one with windows 7 professional and another with windows 8.1. I'm the only owner and user of both. One works with 32 bits and the other (windows 8.1) , 64 bits. Can I use acrobat standard XI in both pc's being the only usuary?

Just in case. I have two pc's one with windows 7 professional (32 bits) and another with windows 8.1 (64 bits). Can I use, with one license, as I'm the owner and only user, acrobat standard XI?. Thank you in advance

Yes, the license allows 2 installs for the owner's personal use. You can check this in the license agreement if you wish.

I am using Lightroom 5.7, 64 bit with Windows 7 Professional. For no apparent reason, I now get an error message when I export a photo, say a raw image to a JPG. However, the exported image seems to be OK. But now I notice that my LR directory of folders in Library view does not show images correctly: If there is a folder with sub-folder(s), the folder will indicate 0 images, but the sub-folders show the proper number of images. What happened and is there a fix? I tried uninstalling Lightroom and re-installing, but problem persists.

What is "Adobe XI" - Reader, or Acrobat?
But either way, 'Save as Adobe PDF' is a Word function, independent of what Adobe software you have installed.

Virtual PC for Mac with Windows XP Professional

I have two questions.
1. My VPC crashed (blue screen of death) on our powerbook G4 15 inch, and it states that the problem is a "unmountable boot volume." Is there I way I can correct this, I have programs on the VPC which would take a long time to reinstall?
2. I am considering purchasing a Macbook and wonder if I can use the Windows XP professional from my Virtual PC 7 with windows XP professional in boot camp? I doubt it, but thought I should at least ask.

Hi and welcome to Discussions,
I don't know about question 1. Might be one to ask in the Microsft forums.

You should probably just download the trial version of pse 12 and see if you can live with it.
Download a free trial or buy Adobe products | Adobe downloads
That being said, have you tried to install pse 1 on your computer?
How much free space is on your hard drive?
Do you have Internet Explorer 10 or 11?
Pse 1 can run on windows 7 x64, provided certain conditions are met.

ITunes fails to launch with Windows XP Professional

I transferred my music to a new computer with Windows XP Professional and now iTunes won't work. It was working at first, but now if I open it this error comes up - 'iTunes has encountered an error and needs to close. We are sorry for the inconvenience' and then to click to tell Microsoft about the problem. Does anyone know how to fix the problem?
Windows XP Pro

There is a good Apple article on trouble shooting launch failures here:
http://docs.info.apple.com/article.html?artnum=302856
Before working though it, it is worth making sure that Quicktime launches and works OK. iTunes can't work if Quicktime doesn't.

HELP....need a good sound card that works with Windows 7 64 bit

I've searched the internet and I'm seeing that folks are struggling with getting sound cards to work with Windows 7 (particularly the 64 bit systems). I know there are stability issues with the 64 bit system but I'm looking to install a decent sound card to improve stereo sound from my HP Pavilion (h8-1260t). The onboard sound is OK, but I'm looking for higher fidelity and the shortcomings of the stock sound chip is noticeable when played through my hi fi system. Don't really need 'surround sound' (I'm not a gamer) but I'm assuming any card that comes with this feature will also produce a quality stereo signal. I also like to archive music from steaming sources and have found a significant loss of sound quality once the track is saved. I'm assuming a good sound card will help with this. Any advice would be greatly appreciated.

Spauld, welcome to the forum.
I suggest finding a sound card that you like and contacting the manufacturer's Customer Service to assure its compatibility with Win7 64-bit. They are the experts on their products. While I am not a fan of dedicated sound cards because their drivers are conflict prone, I would buy a Creative Soundblaster. They have been proven over time.
