So I have this HP DV6629wm laptop that Ive had for a couple years now. The laptop had Windows Vista Home Prem until I upgraded to Window 7 Home Premium in January. Well, recently the audio on my laptop decided to fade out. After awhile it would work again. If I restarted the the laptop it would also work. So I assumed it was something temporary. Well now the audio is not working at all. Now my laptop speaker on the bottom taskbar displays the red cross. Ive checked my Device Manager to see if there was an issue there but the Sound speaker icon was not even there. I did go to HP.com and tried to reinstall the driver update. Which was the sp44700.exe file. Ive tried using the HP Advisor option and tried doing that automatic fix. There I get a yellow triangle with exclamation mark by the information stating that a change was made to the audio driver. Well it doesnt give me much to go by. Ive tried looking online to see if there are other options to fix this issue but I cannot come up with one. I pretty much open for options. I really dont want to take it to a repair guy if its something simple.

What is sp44700.exe?

This package contains the HP Wireless Assistant for the supported notebook/laptop models and operating systems. The HP Wireless Assistant is a user application that provides a way to control the enablement of individual wireless devices (such as Bluetooth, WLAN, or WWAN devices) and that shows the state of the radios for these wireless devices.

There is no Windows 7 driver
You might try the Vista driver-sp40170.exe

Ive checked my Device Manager to see if there was an issue there but the Sound speaker icon was not even there.

well if your sound hardware is not listed in device manager i would think that the the sound device is no longer working or has a serious problem with it, but i would first try the driver to see if anything happens with that.
If I have replied to a topic and you reply and I haven't gotten back to you within 48 hours (2 days) then send me a P.M.

Ok so up till now this is what is going on. About 2 hours ago I turned on my laptop and the audio came back up. I decided to play a movie file I got on my laptop and let it run for a while. Well I get back on my laptop and decide to look for some information online and the audio again is gone. I had to move my laptop to another room so I did turn it off and back on again. Well the same issue is showing again with the red cross on my audio. It does state "No Audio Output Device Installed". Also the troubleshooting came up and gave me the info "Hardware changes might not have been detected" with the "Detected" in italics afterwards with a yellow triangle exclamation mark inside icon. I had already tried installying that sp40170 before and tried again. I get the error message "Driver Installation Failed: Could not find the device for this driver". So that is what is going on up till now.

I called a family member and his thoughts are either the sound card is messed up and needs replacing or the speakers are faulty but my speakers work fine.

Thanks for the help up till now.
