Conexant AC-97 Audio

[Crawfo]

I have Windows 7 beta loaded on my HP Pavilion zd8000 portable, so far everything seems to be fine except the audio.

This computer has a Conexant AC-97 audio chip. The sound is coming out like it is going through a reverb unit set on high. Everything sounds like a bad stutter. Once in a while it will clear up for a few sentances and then back to stutter mode.

I have deleted the driver in device manager to let it re-install but there is no change. I have downloaded the driver for windos vista hopping that may correct the problem but can't figure out how to load it.

Any ideas?

same problem here with the zd 8000.
i have try all drivers for the conexant cx20468-31 ac-97 .
still same problem .
mp3 from 3 min plays 6 min stutter and slowmotion.
i think its a configuration in audio setting is wrong.

Here are some updates on the stutter problem. Both solutions were picked up from the Windows 7 Beta Microsoft TechNet Forum.

You can change the speaker settings to 16 bit, 22059 Hz (AM Radio Quality) but you will loose some in the sound. If you have lousy speakers it won't matter.

The best solution is to download the conexant ac97-61410599.exe driver file. Open this file using WinRAR (WinZip won't work). Extract camc6aud.sys and camc6hal.sys. Rename them camcaud.sys and camchal.sys (in short, remove the 6 from the filename. Copy these files to c:\windows\system32\drivers\.

Be sure to reboot the system so the new drivers will load.

I'd been getting so frustrated with this same problem. It even extended to video being choppy along with the audio. I couldn't help but register just to tell you how much I appreciate your fix. It worked flawlessly and the instructions were perfect. Thanks!

Have tried doing exactly what was required but have still got no sound at all on my HP Pavillion zd8000.......please help lol

I used Win7 on one of my laptops (dv1000) and tried different drivers here and there and managed to somehow get it working on that comp. I then put it on my zd8000 and used the renaming of the files for the audio drivers to work and that worked like a charm.

I have since reformatted my dv1000, with clean install and now i can't get the audio to work even using the above instructions. Anyone else know what to do?

Hey all,

I've got a pickle similar to these gents. Im running Windows 7 on an Hp Compaq nx9600. I've got a Conextant AC-97 audio card and can't for the life of me find a way to get the audio working with this operating system!
Every driver I've tried has failed, everything I've tried has failed. The drivers do not recognize the device what so ever, and if they do, it says theres been and error in the MEDIA. Or something along those lines.
I've had a 32bit XP running with working audio, now Im running a 64bit Windows 7, the machine being 64bit. Is there anything I can do? Has anyone read anything thats worked? I'm still trying things here and there and I'd really rather not down grad to XP again. Does anyone know if Vista would work?
Any info on this would be greatly appreciated.
Cheers

Partial solution

I have been trying to fix a HP Pavillion dv1000 for the last two days. The hard drive went out so I ordered a new one. The owner of the computer did not have a Backup/Recovery disk...I loaded Windows 7 on it. Everything seemed to work fin except audio. It would not load. I tried many drivers and finally turned the laptop over and looked on the service tag. It said the dv1000 was actually a dv1660se. I went to HP's site and downloaded the Installer (sp35811.exe). I then right clicked on it and clicked properties(at the bottom of the list). I cliked on the compatibility tab(at the top of the pop up box). I then checked the "Run this program in compatibility mode" box, selected "Windows Vista" and hit OK. I then double clicked the installer and the video was recognized and installed. It now works on external speakers, but not on internal ones.

I have an HP dv8305. Where can I find this file you mention? Every search result I come up with asks for money or a site membership.

Nope. Didn't work either. I thought I had tried that one before, and I was right. I ran the install utility AND I renamed and copied the files. No change. I'm stuck with my USB device for now.

 

[Bl1ss]

Alright welll. heres the best thing to do.... Get a portable HDD and back up all your files to there and use that as your new HDD for all else that's not programs. Reinstall Windows 7 using your upgrade disc. Its just the startup thingy... It will automatically fix all drivers. i fixed mine that way. and i will continue to do so instead of waiting with no sound. I called HP support and they gave me this crap to.... its not worth spending the for this support. Just wait ....

 

[digitalriverrat]

Nope. Been there. Done that. Not my first rodeo with working with Microsoft OS's. Been working with Windows 7 since June. I had it working at one time but had to repartition the drive to give it more space. Now, after giving the OS 35GB of space to grow into and reinstalling from a fresh wipe, none of the 4 dozen or so drivers I've tried, in many different ways, have worked. I ended up going out and buying a cheap $6 USB audio adapter that works for now. Once Microsoft/Conexant and Realtek get it together finally, I will be able to stop using it. But for now, I'm stuck with it.

I've tried doing all the installs as administrator(I'm the ONLY user of the laptop, why some installs require this when I AM the admin is beyond me), every flavor of compatibility mode, and by just extracting out the actual driver files and copying them to system32\driver and system32\drivers\etc. NOTHING has worked. I've even done driver updates through Control Panel.

 

[Bl1ss]

yeah. i would have done that to... at least till these things get straigtened out. I always do this with other OSs like Ubuntu and my GFX card.

I never tried the file rename approach, but found this link on the HP Support Site which solved the AC 97 driver issue for Windows 7 Ultimate 64 bit on HP DV 8900 laptop:

Business support forums - 64Bit Win7 AC97 Audio driver??

 

[feeeeelfree]

I am using gigabyte in built realtedk audio chip, it was working fine with XP2 & XP3 but it gives a little lower sound with windows 7 and also the Bass is very low. I used all latest drivers from gigabyte and realtek as well, but the problem is same. I am using John Barrel's 5.1 Home theatre and it was working fine with my previous Windows. I love windows 7 & and i dont want to quit.
Pleeeeeeeeeeeeeeeeeeeeeeeeeeeees HELP!

 

[feeeeelfree]

Can I use both Realtek HD audio and AC'97 sound at the same time with my Windows 7?

MY FIX: Running hp Pavilion 1660se with Windows 7 Ultimate (32bit).

I had tried several of the different fixes I found recommended for hp Pavilion 1660se - the best solutions I found was doing the above - to rename the 2 camc6aud.sys and camc6hal.sys files - rename them without the 6, and then save to the c:\windows\system32\drivers folder.

I tried the reboot after doing so, and nothing. After some thought, I decided to logon as administrator (need to enable the administrator account by going into Manage). When I logged in as administrator, boom, the sound blared out. I logged off, relogged in with the normal account, and sound was still present.

I had forgot this type of proceedure from the early Vista days, where some applications just would not work unless you logged in as administrator, and installed with that method.

Good luck!
