Question about Computers & Internet

1 Answer

Computer audio stopped working

I have been trying to help my aunt with her computer. I know enough to apparently cause trouble. I used crucial to do a memory scan and upgraded her HP Pavillion a1610n to 4GB. I also Installed AVG free, adaware and Norman. I used to device manager to update her drivers. The next day she noticed her speakers had no sound. I spent all day today trying to figure out why. The following is an agonizing list of all my failed attempts at solving this one:

I check all connections. I unplugged power strip and restarted.

I used headphones (installed in the out jack in the rear of the PC)to check for sound

I updated and rolled back the sound drivers

In the Run box I typed dxdiag and did tests for sound under the sound 1 and sound 2 tabs
After indicating I heard no sound saw error msg. 19

I checked the control panel....sound settings normal no mute...turned up

I went to system information and under components selected sound and saw the manufacture and drivers...Status read Okay under both. Realtek and an USB one...C-m???

I went to Hp directly and downloaded driver and did a restart. It did state however, I needed another download from windows (UAA-????).
Upon trying to get this I found it was only available for WinXP SP1, 2, and 4.....she has SP3.

I tried to type mplayer into the run box and was told the file did not exist....

I downloaded WMP 11

I really NEED to fix this for her. I wonder if some program was mistakenly removed disabling the sound???? There must be a simple solution to this short of anything drastic. Please tell me where this went wrong and exactly what I can do or who I can call to fix it. It is a challenge as I now am not in front of the system....but will be able to work at it again asap.....Very discouraged and out of answers! BTW the speakers are HP USB desktop speakers. Thanks in advance for any help provided.

    Thanks I will try all of this at my next opportunity I did try plugging headphones into front of tower first. There was no sound from there either. Do you think it would benefit me to run a program such as Driver Detective to solve this? And if so are there any that will go from scan to install for free? And when you say reinstall original drivers from HP recovery disc, just to be sure, you mean the original disc used to set up their computer? That may seem a dumb question, I just really am mixed up in all this and am trying to be clear on every level. Thanks again for your response!

For one thing, there is no Windows xp sp4. It stopped at sp3. So if you needed another download I would check again. Run a custom scan at windows update and see if it offers you any hardware updates, and if so, download and install them.
Then take a look at the following MS KB articles:

You will see from this that error code 19 indicates a corruption in the registry and the suggestion to reinstall the device that is reporting the error. I suggest you use the original drivers from your HP recovery cd and then update the sound after it is working again....Also check the HP support site for your Pavilion and see if there are any reports of known xp conflicts involving the sound card installed in your system.
If this doesn't fix the problem, I suggest you go to and search "windows xp + no sound" and work your way through the list.
Also have a look at this Vista troubleshooter for audio
(There have been vista/WMP bugs involving USB audio devices, but I haven't seen the same in xp)
Maybe check for sound at the front output jack to be sure you didn't jar something loose when installing the ram.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

    It's tempting to use an application like Driver Detective to do the work for you but I would steer clear for the moment, as I have heard some mixed results from "fixes" to peoples systems from such utilities. I haven't used it myself, however...

    You should have a disk from HP called drivers, or a recovery disk that came with the system.

    This will have the drivers for the sound card that were originally installed on your system.

    Here's a link to an excellent online tutorial on updating windows drivers

    (After some further research, I've discovered your HP system has a recovery application program that allows the reinstallation of drivers without the cd, but good to have it on hand just in case..see below.)

    But I just checked HP support for your system and they have an excellent sound troubleshooter online. Have you tried working through the steps there? I would follow their instructions to begin with since it is their installation of XP and they'll have dealt with other similar systems with the same problem to configure the troubleshooter. Click here for a link

    And here's another link to general sound issues for your Pavilion computer

    Work through those HP steps and I'm confidant you'll be able to correct this problem...

    If you still have questions after trying that, please feel free to post back with a comment.

    Good luck!

    BTW, no worries, it's better to ask 100 questions than hose her system.

    Read through the links I sent you so you'll have some familiarity with the ground before you actually have to do the repairs. Be patient and take it one step at a time, and then reboot the system and check the results of what you've done to see if the sound is working...If not, proceed to the next step, etc..

HI.I was watchinglive streaming but there is a eror sudenly.this eror:rtsp:// Can you help me...

Streaming audio/video quality can be affected by connection rate and Internet congestion. Many types of interruptions between your computer, your player, your computer's OS, your local network, your ISP and a streaming server can exist and cause trouble....
When you listen to the live audio/video stream, the sound or video skips, cuts out or buffers if the player doesn't have enough network bandwidth, it will buffer. Try increasing your player's buffering setting.Also:
  • Make sure you are choosing the appropriate bandwidth version of a media stream based on your Internet connection.
  • Make sure you are choosing the appropriate bandwidth settings in an Internet media player or streaming audio/video recorder.
  • Make sure NOT to download applications or files while watching/listening to media streams. Your Internet connection is shared between all open applications including your web-browser, your download manager and your streaming player. Closing applications that use your Internet connection simultaneously with your streaming player may reduce buffering.
  • Close other unnecessary applications that may be open on your computer. Reboot your computer. If you have lots of other programs open, they may be using too much processor time and/or RAM for the player to work properly.
  • Make sure your Internet connection is fast enough to reliably listen to streaming audio and/or watch streaming video online. High speed Internet connection is recommended.
  • Make sure your computer is fast enough. If your computer is old, it might be too slow to play an audio/video stream regardless of what else it's doing.
  • Update your media players and streaming audio/video recorders regularly.
Internet congestion can slow down the delivery of the stream, make it difficult for you to connect or cause buffering. Often the interruption is temporary. Please try to connect a few times at different times of the day, if possible. If you repeatedly have problems connecting, please notify your ISP - there are often quick fixes they can make when they learn about your issue.

Try the above steps you will find a solution to your problem....100% it will work.....

Can I connect a mini plug DIGITAL audio source into these?

Hello bobbobbob, These speakers would work great. First question is: Do you already own these speakers, or would you be buying them? If you already own them, then yes, use them, if not, a more economical solution would be the Bose Companion 2 speakers here: These are about half the price, and have exceptional clarity for someone like your aunt. They also will allow her flat panel TV to plug and play very easily. Please let us know if you need any additional information. Best regards and kudos for helping your aunt out! nightdiver
