Re: No sound on laptop

Does the sound card show up in device manager.
If so its a setting that needs adjusting. Also make sure to check the bios

Require sound software of c707tu laptop

For Audio and Modem, download the following driver packs (install will fail, read below):
Conexant HDA Soft Modem with SmartCP
DriverVer=02/14/2007, (11MB)
Conexant High Definition Audio Device
DriverVer = 02/14/2007, (4.1MB)
After running the two Conexant packages above, the driver files will be extracted to C:\SWSetup\SPxxxxx. The automatic install program will fail but that is expected. Go to Control Panel > Device Manager. Single right-click on the ‘unknown’ audio device and select “Update Driver”. From the Hardware Update wizard:
Select ‘no, not this time’ when asked to connect to the internet, click next.
Select ‘install from a specific location’ (advanced), click next.
Select ‘Don’t search, I will choose the driver to install’, click next.
In the list of common hardware types, scroll down and select Sound, Video, and Game controllers, click next.
In the resulting dialogue box, click Have Disk.
Browse to the folder where SP36090 was extracted (e.g. C:\SWSetup\SP36090) and select CpV30D5a.inf, click OK
In the next dialogue, select Conexant High Definition Audio-Venice 5045. If you receive a warning that Windows cannot verify compatibility with this drive, select ‘Proceed’ or ‘Ignore’ (or whatever option that allows you to continue installing the driver).
When the driver is finished installing, restart your PC. Do the same thing for the modem, except the extraction folder will be C:\SWSetup\SP36089 and the INF is SprtHD5m.inf.
Restart and you should be good.
If you still have an ‘unknown’ PCI device, it is your touchpad and Quick Launch buttons. If you install the software for Quick Launch Buttons, the ‘unknown’ PCI device will go away, as well.

Audio driver for compaq presario c700 PC Note book

I have successfully installed all the XP drivers on the Compaq Presario c700 and successfully removed the bloated pig P.O.S. known as Vista.

You must download the following from Compaq's site:

Driver numbers:

sp34510 - Wireless assistant
sp33411 - Nvidia Chipset
sp33258 - Quick launch
sp35444 - Touchpad
sp36684 - Wireless LAN
sp35682 - Win Audio Bus + updates
sp33549 - Nvidia Video (Go 6150)
sp35270 - Conexant HD Audio
sp34427 - Conexant Modem

These are found all over the HP/Compaq web sites. You'll need to search for the number "sp35410", etc. Some of these are available under the driver pages for the F557US. You'll need to look under both the XP AND Vista sections!!!!

Now, the tricky part!! Listen CAREFULLY!!!! You must:

1. Install all of these drivers one by one, making sure NOT to run the sp33549 (Nvidia VIDEO), sp35270 - Conexant HD Audio, and sp34427 - Conexant Modem drivers!!!! Important! Then, reboot.

2. Run the sp33549 Nvidia Video driver file. It will FAIL! Once it has run, it will create a folder with this path: C:/swsetup/sp33549. Open the control panel, then system, then hardware, then open the device manager. Find the video controller with the yellow exclamation point. Right click, and select properties. Click the 'driver' tab at the top, and then select "update driver". Select 'not this time', then 'Install from a specific location', then select 'don't search', and then finally, select 'have disk'. Select the folder above, and that will manually install the video driver.

3. Do the exact same procedure for the sp35270 Conexant audio card, which will be in the device manager under 'PCI device'. Of course, make sure to use the C:/swsetup/35270 folder this time.

4. You can just double click the modem driver sp34427 to install it, but this must be done AFTER you manually install the Conexant audio!!!!

5. Since it took me three hours to figure all this out, you then send me an e-mail to thank me!

Vista sucks. Be happy you now have XP on this new laptop!!!!!!!
