Too much Background Noise on Line Input or mic Recording !

1 post in this topic

Recommended Posts

I have too much Background Noise on line input or mic I tried some soundcards  even two usb mini soundcards

but I have noise . It seems like it is amplified three times the normal or something like that.


I play guitar for my hobby and I would like to be able to use software like guitar rig (guitar effects)  etc

but this loud noise destroys guitar recording /effects etc.


Can I do anything about that ?

      Some users claim that using VoodooHDA they hear loud bump at system start and sound in system comes with noise.
      Although this can be repaired with existing drivers I propose a version that do this automatically.
      It started silently and have very clear output. The file is compiled as 32/64 and works from 10.6 up to 10.12.
      The sources is in my signature.
      There is a VoodooHDA,prefPane compatible with Sierra

      Now there is a version 2.9.0 by Zenith432.
      It can work with multichannel sound and play it on 5.1 analog system.

      Hi. Hopefully I posted this in the right forum
      This is a long post, and I can't expect everyone to read through it all. So to summarize:
      Got a defective 27" iMac (late 2012 with 2.9GHz i5 and GTX 660M). I want to build the hardware into a Mac Pro tower, without the original (broken) screen attached everything runs SLOW as hell. I've made some progress by deleting a few kext-files, but as I have absolutely no idea what I'm doing I hope someone here can help to improve performance even further 
      I got a 27" (late 2012) iMac for free that a customer at our shop had dropped on the floor. The result was a broken chassis and screen, but everything else was working just fine. The customer got a new one through his insurance, so he didn't care what happened to it.
      Here's a picture of it:
      So after having tested that everything worked perfectly, I decided to remove the hardware from inside. Ideally I want to build this into a Mac Pro tower, and I didn't want to have a big broken screen standing around.
      I was a bit concerned how the iMac would react when I removed the screen. Would I even be able to see the recovery menu on a monitor connected to the thunderbolt port? I expected that this would be a huge problem, and that the iMac would always assume the original screen was still present.
      Fortunately this wasn't the case. With the screen removed the iMac just defaulted to use the one connected with Thunderbolt. This was neat, but unfortunately nowhere near perfect. Because, without the original screen in place, the iMac is missing at least one temperature sensor and it just goes ape{censored} to say the least.
      This means that the fan runs at max speed all the time, easily correctable with a fan control program, but much worse, everything runs so slow that you wouldn't believe it.
      I guess what happens is that the computer under-clocks itself by a large amount. And I'm not exaggerating when I say that it takes 8-9 hours to install OS X Mountain Lion from the recovery menu
      This obviously makes the computer unusable. So I put it away in my cellar until last week where I decided to give it another go.
      Reason for this, was that I was reading a bit about how to make Macbook Pros perform at full speed without an installed battery. And I thought that some of that might apply to the iMac too.
      This is what it looks like on my desk atm:
      So, having since then used the 1TB hard drive in my other desktop PC, I had to go through OS X install-hell once more. It took about 9 hours total, because my internet connection isn't very fast
      I spent most of Saturday evening last weekend messing with it. It wasn't as easy as I had hoped, and when I was just about to give up, I decided to try and delete AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext. Why? Because I seemed to remember these two files being mentioned in the Macbook Pros case.
      I restarted and to my big surprise this actually improved the speed of the computer by a lot! It still isn't perfect, but at least it's somewhat usable.
      Intel Power Gadget says that my CPU is now running at 1.6GHz, it should be 2.9. 
      I tried running GFXbenchGL from the App store. I had tried this when the original screen was connected, so I know that it should be able to run the T-rex scene at about 60fps.
      It ran it at about 9-10fps :/
      Then I found the file called AppleGraphicsPowerManagement.kext. I didn't give it too much thought, the computer was still not working as desired, so I deleted it and rebooted.
      Now the T-rex scene runs at about 30fps!
      Still that's not really good enough :/
      I found this site: osx86.tistory.com/243 which has a description of a lot of the kext files. 
      And I've tried deleting several of those with not so great results This resulted in many cases where I had to wait another 8-9 hours for OS X to reinstall, all while the fan is going crazy  Now I've finally gotten tired of that, so I have several back-up images, at various stages, on an external hard drive, so I can quickly get it back up and running.
      I hope someone here will be able to help me get this thing up and running perfectly The chassis and broken screen was thrown away months ago. This is a list of the components I still have:
      Power supply
      Ram (not the original, gave those away) 3x 2GB 1333MHz DDR3.
      Webcam and cable
      Monitor cable that was used to attach the 27" display to the motherboard.
      Here's what I don't have anymore:
      Microphone (unless it's attached to the motherboard or webcam?)
      Headphone socked (actually a damn shame, because Apples headphone amplifiers are very nice, and now I'll have to find a cheap USB DAC instead. Unless someone happens to know the pinout of the connector on the motherboard? )
      So yeah that about sums it up. It's still a pretty decent computer by todays standards, so I would hate to throw it away. I assume that the answer lies with the kext files somehow, and I hope someone here has enough knowledge about this, and can guide me to get 100% performance out of my system, because I sure as hell don't know what I'm doing
      I don't suppose anything can be done about the extremely slow Recovery menu and OS X installation. Upgrading from Mountain Lion to Yosemite is another 7 hours btw. But I can live with that since it's only needed a few times a year
      Thank you for your time.

      Hi guys! I have managed to finish a golden build on a tricky laptop, and I’m very satisfied with the result as I’m running nearly vanilla and everything is working veeeeery good and fast.
      I am unable to tweak fan speeds via DSDT, I see there are some devices in it related to temperature control but I am not able to reverse-engineer them.
      I’m attaching here my DSDT, would someone be so kind to have a quick look and point me in the right direction?
      Is maybe fan speed controlled by a microcontroller? I’ve read something once, about talking to the microcontroller via DSDT.
      Thank you so much.

      UPDATED 14th January :



      I'm having problems with my ALC662 sound card. On the Back output the sound seems to be ok but I get very low volume and on the FRONT output I get louder volume (but still not loud enough) but when I turn the volume to the maximum I get very bad sound , it starts crackling. 

      I'm using AppleHDA with DSDT.

      Can anyone please help me fix the problem? 

      PS : I'm using Clover.




      Many thanks!

      Hello everybody,

      Within 2-3 weeks I want to buy my first Hackintosh. It's primary use will be music production (Logic X mostly). I've worked with Macbooks for many years but now it's time for a real workstation. Noise level is the most important part of this configuration (besides stability ofcourse), I really want this machine to be as quiet as possible.
      Intel Core i7-4790 Scythe Big Shuriken 2 Rev. B Gigabyte GA-Z87X-D3H or Gigabyte GA-Z87X-UD3H Samsung 840 EVO 250GB (OS, apps) WD Red 1TB or Seagate 7200.14 1TB (samples, projects, documents, etc.) Asus GT640-DCSL-2GD3 - passive cooling Cooler Master Silencio 452 2x Crucial Ballistix Tactical 8GB DDR3-1600 CAS Latency 8, supported by both motherboards Seasonic G-Serie 550Watt PCGH Edition TP-Link TL-WDN4800 2x Dell Ultrasharp U2412M Black, 1920x1200 each This configuration will cost about 1450 euros in my country. I want to use Mavericks as it's primary OS, I won't switch to Yosemite until 10.10.3 or something like that. Here are some arguments and doubts about the components.

      CPU and CPU Cooler
      The 4790 is a little bit faster than the previous 4770 and costs the same, it's compatible with both motherboards. I'm used to dual-core processors, this will be my first quad-core so I'm really thrilled about this little monster! I don't want a passive cooler because it needs more airflow (thus more and louder casefans). I've read many reviews and this cooler should be the quitest.

      The differences between the GA-Z87X-D3H and GA-Z87X-UD3H are: 2 SATA ports, 2 eSATA ports, Display Port and a different audio chip. All of those things don't really matter to me. 6x SATA is enough, I don't need a Display Port since I use a dedicated GPU and I won't use the onboard audio at all (I currenly use an Apogee Duet 2 and will buy a 19" interface later this year). I tend to go for the UD3H, not because of the extra features, but I found a lot more success stories with this board. I've read stories about the D3H where a beta BIOS is required to gain stability. I need the latest BIOS due to the Haswell Refresh CPU.

      I can't choose between the WD drive the Seagate drive. The first seems more quiet but not exactly built for my needs, it's primary use is for NAS-systems. The Seagate seems noticeably faster but is also noisier. I have no idea "how much" noisier this drive will be.

      Case and PSU
      The Fractal Design R4 has been recommended many times and there are no reviews between this case and the Coolermaster I choose. The Coolermaster gets very positive reviews and I like the design better. The Seasonic is very efficient and must be very quiet. I'd love to hear suggestions for quiter PSU's, this is the best I could find.

      Graphics and dual monitors
      I guess 2x 1920x1200 won't be a problem for a Geforce GT640 2GB. I won't use it for heavy gaming or video editing or something like that. It's the fastest passive GPU I could find which is OOTB supported. I don't want to take any risk with buying a HD7750 or R7 250. 

       I'd love to hear your comments and suggestions. Thanks in advance!
