My solution for No Audio -- Conexant drivers and Windows 7 x64

[decoe]

I upgraded my HP Special Edition L2005CU from WinXP 32-bit to Win7Ult-64bit and the built-in audio device did not work. I used a USB audio device as a work-around until I found this post. This work-around worked beautifully. Thanks a lot for figuring this one out. It is very disappointing that HP could not provide an updated driver that is this simple of a solution to their L2000 customers. It's an outstanding product to be able to handle win7ultimate 64-bit 5 years later with only a memory upgrade and they should be supporting it better.

Thanks again.

Hi there. Nice to see someone is trying to solve problems.

I tried the solution you provided, but with the 32-bit files. My problem is that I'm using an HP Pavilion zv6000 series and I don't know how to modify the .cva file, under [System Information].

Any idea?

I tried to leave that part out, but I got a FAILURE installation.

Under Device Manager, right click "Multimedia Audio Device" under "Other" and choose "Update Driver" Then" Browse your PC" and "Choose from a list". Select "Sound, audio and game controllers", then Conexant, then "Have Disk" . Browse to C:/swsetup/sp34789/ and open "*.inf". Now choose "OK" and ignore any warnings about incompatibility, WHQL, etc. Give it plenty of time, you might think you are in a loop, but you are not. Congratulations, you are done.

If it works, Kudos are appreciated.

I tried that, but I get a Code 10  Device cannot start, or something like that. It shows installed, but with the lemon.

I have read this carefully, but am unsure about 32 bit modifications is it all the same as the 64 bit, except for those files you point out?

Also, does this fix apply to all of the audio features, or just the sound - in other words does it include built-in mics?

I have a HP Pavilion dv2104eu upgraded from XP pro to Win 7 x32 Home Premium,  The sound works but the built in mic does not work at all, nor does an external mic.

The system has Conextant High Definition Smart Audio HD2 sound, AMD Turion 64 x 2 and nVidia Video

FYI and THANK YOU!! This worked perfect on my HP Pavilion zv6000 laptop. The 64-bit Vista driver works perfect!

Hey, what about mass storage driver?

(e.g. the SD, MS/Pro,MMC, SM, XD memory card)

I can't find a driver for it either ...

Any clues?

Thank you.  I've just upgraded my HP laptop zd8000 and this worked great.

Hi,

I have not been here for a while and saw this post. I am not sure if you have found a solution yet or not. I think that most people are moving to 64 bit OS and the AMD Turion 64 x2 is certainly capable of supporting a 64 bit OS. Be sure that you are using the correct set of drivers that I mentioned in this thread either 32 bit or 64 bit. In one of my posts I tell you where to find them. In my experience, this fix works for sound in as well as sound out, i.e. the microphones should work. If you have not been able to get the sound to work, then the mics should not work either.

As for this fix, the CVA file mods are just a cool way of doing this. Run the appropriate sp#####.exe file by double clicking it. It will create a directory under c:\swsetup\ and in that directory lie the drivers that you need. It will then stop and tell you it can't go on for some reason and close.  This is desired. Now go through a manual install which I described a few posts above.

Hope this helps.

Thanks for the info. I had to do one more thing though..

The audio controller came up on the device manager under "Other devices" with an unknown manufacturer. All of my attempts to load any driver software all produced the same "cant find Media device" errors. After many failed attempts, one of them loaded the driver for a Realtek board. This didn't fix it BUT it did cause the board to show up as an AC97 Audio controller under "Sound, video and game controllers" in the Device manager rather than under the "Other devices."  So the next step was to update the driver using your procedure, and that did it.

Interestingly, when I removed the Realtek software from my laptop, it killed the audio. One or more of the Realtek files need to be on the system.. I don't know which one but I don't feel like looking for it. As a compromise I deleted about 20 MB of files from the Realtek directory, and all is OK so I'm leaving it as is.. everything works, and I am a firm believer in "If it ain't broke, don't try to fix it."

This was on a DV5215us laptop, by the way.. and it's on HP's list of supported hardware for Windows 7! That list needs to be revised.
