Acer Realtek 4820T Audio Driver

Hi all,

First post on these boards. I recently bought an Acer 4820T which has a sound issue; audio is stuttering when the disk i/o is active. I uninstalled the driver and the stuttering was gone, which on the other hand left me without access to my card features. If anyone knows of a good driver for my Realtek ALC269 card please let me know as the one posted on the acer site isn't any good. Thanks

 

Have your tried updating the driver rather than uninstalling it?
The most recent version is available at Realtek support site.

What HDD is that- Western Digital by any chance?

 

Hi downloads, thanks for getting back to me. I tried several drivers with no luck, still the same problem. The HDD is a Hitachi and the problem doesn't persist when the device runs on the microsoft native driver

 

I have had a problem like that with a Realtek sound chip and it was indeed driver related but they have corrected quickly.
If the most recent driver doesn't help you there's not much you can do (or at least nothing comes to my mind).
Check if your BIOS is up to date and see if the problem persists when Realtek Sound Manager is off (kill RAVCpl64.exe)

 

Thanks for your counsel downloads. I'll follow your advice and will give you some feedback. There is really not much to do if its from realtek's behalf. However from what I gathered about the problem, I haven't heard of anyone with the same issue on the 4820t. So I think it boils down to a specific malfunction on my rig rather then a generic one. Another thing that I noticed is that windows' mixer (I'm on win7 x64) volume bar in non-existent despite having control on volume levels.

 

Try bootable Ubuntu USB Flash drive (google for guides on creating one). Once you load into the system, play some kind of an audio file, WAV file for example, from your HDD. If you don't get stuttering problems on Ubuntu, then it is probably the Windows driver...

 

Sorry I neglected to mention but I already booted linux from live cd (messed around with some audio files as well) and yes everything worked fined, so it definitely is a driver issue. Strange thing is it seems I'm the only with this issue

 

If you run out of ideas just do a clean install.
It's possible that something got messed up in registry or there's some kind of software conflict.
