Hauppauge PVR-150 Capture, Audio Static/Noise IVTV Composite input

Hello,
This is my first post.
I have been migrating from Gentoo to Arch after 7-8 years using gentoo, I think Arch is great. even though precompiled packages have there downside. anyway.
I have problem with static/noise audio when capturing from Composite using IVTV, im running kernel 3.0.4 arch kernel.
I have 10 Hauppauge PVR-150 (+1 PVR-500) Cards running, the problem occurs in a random card after reboot.
Video is fine on all cards, but sometimes the audio on either one of the 11 cards get static/noise in the audio background.. sometimes allot, other times just a little bit noise/static.
I tried the wiki, and searched the forum, but can't find a solution, can anyone help me??
I can provide sample (cat /dev/videoX > sample.mpeg) if interested.
See dmesg: http://pastebin.com/U2JnJ0Zr
Thank you

Hello,
changing to constant bitrate seems to correct the problem,
v4l2-ctl -d /dev/videoX --set-ctrl=video-bitrate-mode=1
and then remember to not have the capture source audio volume to more than 75%.

[SOLVED] mythtv - No picture using Hauppauge pvr-150

Hi All,
I have just set up mythtv but cannot get a live picture using the Hauppauge pvr 150. The card is working (thanks to enrique) and can both stream video and record video either live or in a cron job. I am attaching the cable directly to the card instead of using a digital cable box. This limits the available channels but thats OK since this connection probably won't be used that often.
I don't recall seeing any options specifying whether the cable connection is analog or digital, nor do I recall seeing any options pertaining to the video card. I don't know what I'm doing wrong so any and all tips will be appreciated.
Thanks
Larry

Problem Solved:
The dodo (Me), kept putting the card in as "analog v4l device" which is how myth set it up.
It should be MPEG-2 encoder card (PVR-x50,500).
I just wasn't being careful enough to check all possibilities.
Seems to be working.
Maybe that will help someone.

Capture audio static with Leopard?

I just upgraded to Leopard and started capturing a new project with FCP. I now have static in the audio I didn't have before. Anyone else experiencing this. I've switch cables, drives, video playback decks and still get added static on all tapes. The audio on the tape when monitored with earphones is static free. Any ideas? Thanks.
Gary

Thanks for the reply. All cameras are set to 16 bit audio. Nothing has really changed except the Leopard OS upgrade. I am getting a warning box about the audio possibly not syncing, but there is no sync problem. I'm just curious if I'm the only one having this problem with audio static on capturing after the Leopard upgrade. Thanks for any help.

QuickTime always has static noise while playing audio

Every time I open an mp3 (or any audio file) in QuickTime, it plays a lot of static noise in the background. These audio files work fine in other applications (iTunes, VLC, etc) so i know the problem lies with QuickTime. I have tried re-installing it, but the same problem keeps occurring. Does anyone else have this problem and know what's wrong? I'm using QuickTime 10.3, on Mavericks 10.9.5

This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum.

Audio makes buzzings/static noise

When audio is present, whether through the speakers or headphones, it is accompanied by static noise like a broken speaker cone makes- buzzes and static

Solved the problem myself; found there was an add'l clip causing the noise.

TS3581 Crackling static noise in audio with 30 pin lightning adapter when battery is full

Anyone else get a really bad crackling static noise through the audio when using the 30 pin lightning adapter and the battery is almost full? I am using an iPhone 5, BMW iDrive with the Y audio and USB connection. I did not have this problem with the 4S and the normal 30 pin connector. The lilghtning 30 pin adapter seems to create interference when the phone's battery is nearly full. I also see the warning message indicating that charging is not supported - and according to the troubleshooting guide this is normal - but what about the noise????

Alright, another update: I tried another iPhone 5, which did not charge, and an iPod touch (without the lightning adapter, obviously), which also did not charge. Additionally, I tried the lightning to 30-pin adapter with an old sync cable and my computer, and it worked fine. At this point, it appears that the problem may be in the MDI cable coming from the car, rather than the adapter. Perhaps it was just coincidental that it stopped working at the same time I upgraded.

Capturing Audio from DAT

Hello,
I'm trying to capture audio from a DAT deck (Tascam DA-20) into FCP HD by routing it through my JVC BR-DV600U DV deck (RCA output from DAT, RCA input to DV deck, Firewire into FCP).
The DV deck's input is set to line-in, and the audio is being routed through (audio meters on DV deck mimic those on DAT deck, and I can hear the audio through the headphones jacked into my DV deck).
However, when I try to capture the audio on FCP, I am unsuccessful, prompting the following window from FCP: "Error: Final Cut Pro HD was unable to read the movie file just captured."
Now, I use the same set up I described above to capture footage from my Beta deck into FCP with no problems (route Beta signal through DV deck and firewire it into FCP). This leads me to believe that perhaps the glitch lies within my Capture Presets.
At first, I tried to capture the signal as an Audio-Only DV NTSC 48 Khz/Non-controllable device. After that failed, I tried to create my own capture preset, but am not sure it will make a difference, as the only input choices I am given are DV Audio, Built-In Audio, and None.
Any suggestions?
Thanks.

Why not capture the audio content outside of FCP, check the sample rate for 48Khz/16-bit, convert if necessary, save as an AIFF file, and then import that resulting sound file into FCP?
Any good audio app, including STP will do captures.
You are probably going to need to do some cleanup on the audio anyway before you use it, so why not just use an audio app to do it beforehand?
Besides, if you have an audio device (PCI card or Firewire device) in your Mac, you can use the S/PDIF port for your connection to the DAT and do a digital transfer when you import.
As I understand the way you are doing it now, you are taking digital content from the DAT, converting it to analog for the connection into your deck, and then re-converting it into digital when you capture it back into FCP.
One big advantage of digital audio (and video) is to avoid generation loss and added noise during transfer if you go D-to-D.
If you don't have an audio card or Firewire A/D audio I/O device with S/PDIF ports in your Mac, then see if you can find a friend who has one and can do the transfer for you. Then he can give you the file on a CD-ROM.
That's what I'd do.

Why is the sound coming from my computer have a lot of static (noise). ?

Product Name: HP G62-223CL Laptop Computer
Operating System: Windows 7-64bit
No error messages.
The Stereo Mixer - Realtek High Definition Audio produces noise (static) unless muted. Is there a way to correct this problem with software or is the audio board defective (broken)?

Thanks for your response. Called Tech support and they suggested Uninstalling the audio board driver. That worked. After booting with an updated driver the noise went away. Thanks again...gtc

Consistant Static Noise noise changes when performing actions on laptop, need he

I have a Sound Blaster Li've 24-bit External sound card which I have my DJ equipment connected to. The problem I am coming across is static noise coming through the speakers. The sound is there when the audio board is powered on?or off. I have already did basic troubleshooting and I refered to theKnowledge Base on this site.
Power of laptop is in a different source, soundcard has the latest downloads, speaker cables are fine etc. I want to check the Bios on my computer but I don't think I am that tactful to do this. Anyways, I will cut and paste my message I started on Mediamonkey.com, I am GDTRFB66. I basically wan't to know if there is a filter or a better sound card I can purchase to knock out the interference the computer is making. I Usually only run 2 speakers, sometimes I will connect smaller speakers through my audio board and run it through source. Also the ststic noise is there when I just connect my computer directly to my laptop and it uses the onboard sound card, so I doubt it is an issue with the sound card.
I really would like some additional help here is the post I submitted on Media Monkey......Next Message

Thanks for the suggestion . As soon as they hand me my laptop at the store in 45 minutes time I shall try the disable and then re boot as you suggest.
so far they sent me this; Disk has no problem.They may have more to say to me re the flash drive and results of storage diagnostics and ASDs ( what is this? ) when I see them .
The case repair is redundant to the problem I am having but if they give me a new one worth $399 i will not complain,eh.
Problem Description/Diagnosis
Issue: MacBook Pro is running extremely slow. Specifically IPhoto
Steps to Reproduce: Attempted to repair disk, no issues found.

USB Microphone static noise OSX Yosemite.

Same thing as the title recently upgraded from late 2008 iMac using Mountain Lion to a late 2013 iMac using Yosemite and now when I plug in my USB headset into one of the 4 USB slots the microphone is robotic and static noises appear. When I plug the headphones into the Usb slot in my keyboard the mic works fine. Anyone else experiencing this?

What version of Premiere Elements are you using on your Mac computer? Is your USB microphone a standalone or part of a USB web cam type device?
Classically the Adobe ReadMe mentions that USB Microphones do not work with Premiere Elements. Yes, I have seen a report that USB microphone would be expected to work with correct Control Panel and program Edit Menu/Preferences/Audio Hardware ASIO settings at least in versions 10 and 11 Mac.
Please see a thread from last year and its discussion on the matter.
I can't get premiere elements 11 to see my usb microphone?
Some have found a few USB Microphones that do work in Premiere Elements (any version), but those reports are scattered. So to answer your question
will an other usb microphone work?
maybe or maybe not is the best answer I can offer at this time.
For troubleshooting purposes, can you create the narration in a free audio editor like Audacity and then
import that narration into the Premiere Elements project (Add Media/Files and Folders) without issue?
http://audacity.sourceforge.net/
Perhaps we can encourage Premiere Elements users versions 4 to 13 who use a USB microphone to post in your thread (for informational
purposes) the brand/model USB microphone that has worked for them.

Realtek alc 892 static noise

I have problems with on-board Realtek alc 892 audio. Im running out of ideas of what could i do to fix this static noise problem.Im using Logitec z-2300 speaker.I have tried headphones too and all of them have this static noise coming trough.There is no noise with volume at 50% but beyond that it becomes audible.It kinda sounds like scratching vinyl plates or makes popping sound.whenever i move my mouse or type something the noise is coming in.Also when the cpu is under work(while loading something when i click the noise comes in)there are leds on my z77a-g45 mb that shows cpu activity and when they flash the static noise/whine is present.This noise exactly fallows cpu work.At high volume there is always barely audible electrical hummming...Disabling on-board audio in Windows does not have any effect at all.I get the same thing in bios...
What i have tried so far:
1.Uninstalled/reinstalled audio/video drivers.
2.Muted microphone,hdmi audio and recording.
3.Switched cable positions,including mouse and speakers jack.
4.Tried other wall contacts in my room.
5.Updated mb bios to latest v2.7
6.Reseated hardware inside pc/cleaned of dust.
7.Cpu oc does not cause this.Same problem with stock clocks.
PC spec:
I5 3570k@ 4.0ghz
Cooler:Coolermaste hyper evo 212
Msi Z77A-G45
Mem:Crucial Ballistix Tactical 2x4gb 1600mhz

I have the same problem, have tried 3 PSUs, and nothing, the only solution was to buy an pci-e sound card.
The problem appear when MSI updated BIOS 2.0 to 2.1.
Please don't hijack other people threads, and why don't you flash back to 2.0 or the newest beta? Start your own thread and we can discuss this.

I took gtx 560 ti completely out but no luck.Also took psu out temporary and placed it on the floor.Not even a slight change
Taking the psu out doesn't really do anything, taking the mainboard out and placing it on a non-conductive surface is what I was recommending. Test with the cpu, cooler, 1 stick of ram, igd and y our mouse / keyboard. After some other things though.
Testing with a different PSU would be good to rule that out as the culprit.

Static Noise

I posted this on the wrong ipod thread, since I found out I own a 5th gen. Anyway, I've found some threads about the static noise problem in the Ipod classics. I wonder if anyone has experience connecting the ipod to a sound system such as the Kenwood or Pioneer Avic-X3, the latter I now own. These car systems are state of the art, and one of the few systems who allow direct control over the ipod. I wanted the very best, so I specifically bought the Ipod for this purpose.
The problem is the audio quality because of static noise is simply terrible. Even if no music is playing there is a continues buzzing sound through the sound system (probably the HDD) which gets worse when you turn up the volume. turning off the EQ in the ipod makes no difference. Pioneer blames the Ipod, and by checking various threads it seems this is a genuine problem. What advise would you guys give me, is it worth raising this with Apple by going back to the store? I can't believe I spend more then 2000 Euros on this entire system and having this crap quality.

Hi,
To start with, download and install the latest IDT driver on the link below.
ftp://ftp.hp.com/pub/softpaq/sp51501-52000/sp51930.exe
After the installation has completed, restart the notebook and see if this has helped the issue.
