    Hi, I have got the same problem, I bought the laptop from Germany so the operating system was German so the first thing that I've done is to format it and install Windows Vista Business in English, I tried the drivers and the same problem happens... even without rebooting..
    I have tried installing another version of the driver (Audio_Realtek_v6.0.1.5449_Vista) , the problem disappeared, but the sound was really poor, the subwoofer didn't work, and the sound was like an old radio.. please help

    I have a similar problem, there is sound but only the basics, like on Messenger or when you have a direction pop-up to over-ride a saved doc etc. However playing a game, video and the likes it plays briefly and then crackles and disappears. I have checked and all drivers seem fine, the system obviously has sound or I would not even hear basic sounds. The only thing I remember doing was uninstalling the Acer Widget (annoying thing) and after that I have had this problem. Problem is I don't even know how to retrieve the Widget so I can test to see if that was indeed the problem.

I have found a perfect fix for this problem. You MUST update the BIOS in order to fix what Acer calls BOBO audio problems. (No one knows what BOBO means.)

That link is from the Acer Europe website, but the update worked on my Aspire 7720 here in the US. I did it easily by downloading the zip and then extracting folder. Then I extracted the executable from that folder and ran it. It will detect your current BIOS and ask if youw ant to update. I clicked yes. Then it reboots and the audio works as it should have always!

Secondly, there is another change I suggest. The 7720 series laptop comes pre-installed in device manager saying that it is using IDE when in fact it is all ATA. I suggest going to the device manager and right clicking both IDE channels at the top of your list in IDE ATA/ATAPI controllers. Then reboot and vista or xp will reinstall these automatically as ATA. I have honestly noticed a performance difference based on that small difference.

I got most of this information from: and

It's a defininite driver problem. Adelete and reinstall of the driver cures the problem until the computer is rebooted the the problem reappears.

How to enable bluetooth

Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

Burning movies on the computer , playback fine on two computeers , will not play on ONN portable player used DVD-R

Burning dvd\'s is always a crapshoot when you have multiple machines. Computer drives are more tolerant on playback - the problem lies with your other, independent playback units. That is why in your main viewing area it is important that you have a few units so that if disk does not play in one machine, it will play on another. Has to do with the individual differences and calibrations of the machines involved. Store bought dvd\'s have less problems because their laser reflectivity is always higher than disks you burn, and therefore, easier to read properly. Price of the unit has no reflection on ability to properly read the disk. Sometimes and often, a cheaper machine will work better with copies - you never know.

Bluetooth & sound

Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

No disc problem

You would only receive that error if your player in unable to read your disc, basically saying there is no disc in the unit. This problem arises mainly due to the Optical Pickup(laser) probably failing. For more information, please visit my website at Thank you.
