Bad scratchy noise from speakers, but speakers OK. No IDE ATA/ATAPI???
Hi! Please bear with me ... I will not be using the correct terminology, but hope I explain myself OK all the same!
I have a DELL studio XPS PC With Windows 7. I used to have a DELL screen, with a speaker section attached, which belonged to my previous DELL. (Altec Lansing 5650 5.1 Surround Sound Speakers with Subwoofer set).
I ditched this due to the plastic attachments breaking, and the fact that I could only get sound from 2 of the speakers, not all 4, after changing my PC. I therefore thought it was an unnecessary amount of "hardware" kicking around my desk just for getting sound out of 2 speakers.
So, I bought Creative T15 Wireless (Bluetooth) speakers, although I use the wire directly into my PC due to not having Bluetooth. These worked fine to begin with - OK sound, so not complaining.
Now, I'm not sure whether this happened simultaneously with buying a New screen (a Samsung 24") but all of a sudden I started getting very scratchy noises coming from the left speaker. This noise comes even when unplugged from my computer. I contacted Creative who said that if the speakers work when attached to my ipod/iphone then there is nothing wrong with them:
Now, I cannot find the IDE ATA/ATAPI Controllers icon, as it is missing from the list. Have I unwittingly deleted something, and can I reinstall? Or is it relatively normal for this to be missing from the Devices manager list?That means the speaker is good. If speaker is faulty, the issue will remain the same no matter as to what device you connect it. Issue seems to be with your computer sound card's audio out. Check the settings in your computer, playback application settings . Reinstall/update the computer sound card driver if required. Also make sure DMA is enabled for the hard drives in Windows 7.
How to enable DMA:
- Click Start Control Panel Hardware and Sound Device Manager. If the User Account Control dialog box appears, click the Continue button.
- Double-click the IDE ATA/ATAPI Controllers icon.
- For each ATA Channel in the list, right-click and select
Properties.
- Click the Advanced Settings tab and select the Enable DMA
checkbox.
- Click the OK button.
I replied to Creative, and received the following answer:
Hence trying this forum, to see if anyone understands the issue.There is no noise if you change the audio source like your iPhone . Correct? That means speakers are good. If the noise exists even with alternate audio source means the issue is related to the speakers.
IDE ATA controllers are usually placed below Human Interface Devices in Windows. Mostly DMA is enabled by default. If incase its disabled , it can create audio distortions when playing digital contents . You may contact your PC/Laptop manufacturer on this for assistance.
Thanks, in advance. :)
