Question about Dell Dimension 5100 (D51L1) PC Desktop

1 Answer

Waves not playing yet mp3s do.

I CAN play MP3s and CDs and hear the music on my myspace page when it loads.
I can hear music on other people's myspace pages when it's imbedded into the page as an mp3; however I cannot hear the music on peoples Myspace Music Players. This started late yesterday afternoon and of course I presumed this to be a myspace problem and didn't give it much thought.
When I turned on the computer today something visually went by fast (maybe a small gray java window) like it was installing something (maybe windows haha) but it may have said Windows Media Player. When it finally came up I opened Windows Media Player and tried to play an MP3 and it said I was missing a codec and provided a proper link. I clicked on the link and immediately got the codec and now the MP3s play.
But still Myspace Music Players don't play.
Here is the bad part that made me realize it wasn't a myspace problem. My midi files do not play nor do any of my webpages play the midi files on them.
The only change I made was yesterday I deleted X-Vid codecs that I had downloaded months ago and did not use. I used add/remove programs and removed X-Vid.

Anyway I did a full Nortons scan and was clean. Then I ran a full Ad Aware Scan, and ran CCleaner as well and nothing is very wrong with my system other than no sound with midis.
I finally decided to do a full system restore to yesterday that failed as it said I had made no changes. Then I tried a system restore to last Sunday and it said there were no changes made and so no restore would be made. So it probably wasn't the X-Vid delete that caused the problem.
In troubleshooting in Device Manager I tried to update ALL the audio drivers and it said I had the best (latest)version of all the drivers. I clicked on everything individually and then ran the troubleshooters which took forever.
I have no yellow exclamation points and it says all things are working properly.
except for one thing. when I click on Unimodem Half-Duplex Audio Device it says this device is working properly. When I click on properties and then again on the tab that says properties and then on the words Modem Wave Driver it says
Status:Driver is enabled but not functioning properly. Yet previously (higher up) it said it was fine. (this is device 5.3.2600.2180)

Also if I click on Control Panel, Sounds and audio devices,sounds tab.... and click on a sound.... it used to let you preview the sound but now the tab is gray.
I don't know what to do next. If my sound card was unseated my mp3s wouldn't play. I have rebooted several times.
I have tried reading Dell forums (I have a Dimension 5100) and I have read forums for Unimodem half-duplex audio device and forums for Sigma tel High definition audio codecs although that one says its working properly. Since it seems to only be Midis affected and it is called a Modem Wave Driver, could the dial up modem be unseated? could it be that simple?

    I worked on this three days. Hooray it's fixed. Unbelievable! I did somethings in the registry keys and everything is well. I actually went to a message board and clicked on a registry patch someone posted. Yes I clicked on a link from a complete stranger knowing it was going to mess with my registry. I did back up the registry and my sounds were restored instantly. amazing! It was a zipped file with 3 small registry files. I cannot believe it worked!

Nopes. What seems to be was a suspended application installation (probably you or somebody qho used your computer just before it happenned). You can try System Restore. It should roll back that kind of file extension change. Hope it helps, good luck.
Solution #2: You can do as well if the system restore does not work to reasign the software that is going to open that file extension (so far I know the change has been made to MP3, WAV, MIDI.). That you can do it by opening my computer, then go to "TOOLS", inside of it go to "FOLDER OPTIONS", then choose the tab "FILE TYPES". There, scroll down until you see the extension "MP3" and place your mouse arrow on it. Now below it you are going to see two choices that you can click on, click on "CHANGE" and choose your favorite program. Again, I hope it helps...

Hi i have a sharp hp22 i ham trying to play normal dvds on it ? is that possible

In general, Blu-ray player is compatible with DVDs. So you can play DVD on Sharp Blu-ray Player. However, some pretected DVD can be played on Blu-ray Player. As for How to remove region restriction on DVD for playing on any Blu-ray player, just follow below steps.
Step 1. Download and install Leawo DVD Ripper on your computer, and then kick off the program to enter the main interface. Import the DVD with copy protection on your computer by clicking Add Blu-ray/DVD. Once the protected DVD is selected, you will be provided three options to import DVD file(s): Full Movie, Main Movie and Custom Mode. Full Movie is to import all titles, and Main Movie only imports the longest title by default. And you are able to choose titles for importing under Custom Mode.

Step 2. In a drop-down box named "MP4 Video", you can click "Change" to enter the Profile panel to select the output format.

Step 3. Set a directory under "Save to" box. Finally, hit "Convert" button at the bottom to start the conversion process. During the conversion process, Leawo Blu-ray Ripper will automatically remove the disc copy protection and then begin the conversion in several minutes. With Leawo DVD Ripper, it will help do Blu-ray players play all region DVDs.

I want to burn music from MP3 Rocket. It is downloaded but cannot find ANY info on the steps to burn onto CDs.

Open the music you want to burn in Windows Media player... at the top you will find an option to burn the files to disc - this will create an Audio disc that can be played in any CD player.

If you want to back up the Mp3s as data files you should simply insert an empty CD a window will pop up asking you what you want to do - select add files to CD (burn data CD) and then select the MP3s you want to burn... these files will not play on normal CD players.

If this helped you then please help me and vote kindly.

Music compatibilty problem

I have the same phone and have no problems playing either wave files or mp3s. Make sure that your music is in one of those formats. If you need software in order to convert your sound files, I recommend Goldwave. It is simple to use and has a wide range of applications. A trial version can be found on the web site. Good Luck.

Looooooong time to load and start playing MP3s

Hmmm, the Zumo doesn't have a harddrive, it's flash memory. The best place to store mp3's is on a fast SD card, and don't get the biggest size and cram it full, I had like 100 mp3's on a card adding up to almost 450 mins of music, started up without a problem. Not as fast but pretty snappy!

Won't format and won't play mp3

try loading files on different bit rates and see what bitrate your player can play. some player wont play files that are directly copied to the player, it needs a certain software to encode it to its standard format. sony walkman is an example, it has its own software to encode files from mp3 to its own supported format.
