ALSA USB Headset Crackling Noise

Hi, I'm having some problems with my USB Headset that I'm using for my sounds, which when I play anything with sounds in it, it gives me crackling noises. I'm using ALSA and my headset is the Razer Megalodon, however, the headset works perfectly fine on Windows, just not on linux. I tried all of the usb ports on my computer and all of the solutions in the wiki for ALSA, such as using and installing asoundconf from AUR and adding "options snd-usb-audio nrpacks=1" to my /etc/modprobe.d/modprobe.conf with no luck.
I even tried using PulseAudio, hoping that I'd get some better results, but sadly, I still get crackling noises. I even tried adding "tsched=0" in my /etc/pulse/default.pa with no luck.
Here's my lsmod: https://gist.github.com/anonymous/5333572 or if you prefer: http://ix.io/54h
I'd really appreciate it if someone could help me fix this problem, thanks.

Doesn't help me either, I tried adding that to /etc/modprobe.d/modprobe.conf and still doesn't work. I tried changing from snd-hda-intel to snd-usb-audio and that doesn't work either. I even tried typing in: "modprobe snd-hda-intel power_save=0 power_save_controller=N" and that didn't work. Also tried changing the snd-hda-intel of the modprobe command to snd-usb-audio, still doesn't work.
Anyone else have any ideas? This crackling noise is really obnoxious and makes watching things unbearable.
EDIT: I didn't fix the problem, but what I did was remove ~/.asoundrc and ~/.asoundrc.asoundconf. I edited /etc/modprobe.d/modprobe.conf and removed everything and added "blacklist snd_hda_intel" so I didn't have to deal with any onboard soundcards. I removed asoundconf from my computer and removed pulseaudio (just in case). All I have installed that's related to sound is: alsa-lib, alsa-plugins, alsa-utils, and lib32-alsa-lib. I'm going to be working with a completely clean configuration of ALSA, so if anyone has any suggestions please go ahead and let me test it out. Obviously if anything relates to snd-hda-intel, it won't work on mine because I blacklisted it, thanks. Also, what was funny enough was that when I completely uninstalled everything and had a clean configuration, my sound was working completely fine with no crackles for the first time! But when I restarted my computer, it went back to crackling for some reason.

USB Headset crackle

I swapped to a new MBP a few weeks ago (unfortunately just before the latest upgrades!!). Since then there's a constant crackle on my USB Logitech 250 headset. Never before. I've tried both USB slots, a hub - all the same problem.
Any ideas to solve this?
Thank you

USB Microphone headset and noise

Hello there !
I've done a little research on these threads before coming here, but no luck, I found nothing…
Im the owner of a refurbished MBP Penryn 2,5Ghz and a Plantronics Audio 650 USB headset since october.
2 months ago (around this), I've begun to sometimes experience some constant parasite noise with my microphone (Skype chat, Garageband, QuickTime or Übercaster recording).
I though about a fan noise, or power noise… but it appears to be absolutely not predictable.
I have done some tests with temperature viewer and fan speed viewer… on some days after utilisation, I have this noise. The CPU can be at 55°c, GPU at 60/68°c (and some others).
The fans are constantly to 2000 rpm during these issues.
On other tests, like a morning I made my MBP warming, keeping these temperatures, but no noise.
Well, Im at this moment using it with iTunes playing, battery charging, USB mouse and headset connectd, FireWire 800 working, the "noise-temperatures" reached… and no noise with the microphone.
I contacted Plantronics, who asked me to make a crossed test, but I was not able to reproduce it on an Intel iMac or a Titanium G4…
Is there someone here who have some ideas about what is going on ?
I suspected the headset, the hardware, the 10.5.6 update… even my 4 Gb of RAM installed in November… or the dust in the colling access !
But I cant reach a constant parameter to solve this…
Thanks in advance !

OK, thanks for the reply.
I seem to recall that certain device types, like disk drives and audio devices, have a standardized USB interface. That is, no device-specific driver is required (assuming that they design to the standard, of course). I guess then what you're saying then is the iOS devices don't have that standard audio-device driver. I guess that's a not-unreasonable choice on Apple's part.
I suppose another possibility might be somebody making a (small, light, preferably in-line) adaptor from USB audio to 8th-inch pin plug - essentially a very-small, very-simple USB-interfaced A/D-D/A). I looked for such a thing on Amazon, and didn't see anything like that, but perhaps I didn't use the right keywords. Then again, such a device would presumably need a battery, which would probably contradict the "small and light" criteria! :-)

Soundsticks (USB) crackling noise

Hi,
I experience constant static crackling noises from the Soundsticks when they are connected to the Computer (an iMac 20" from late 2006).
No matter if the volume is turned down or muted on the Soundsticks, no matter if I select the internal speakers as the output source, it does not go away.
Does anyone else have this problem?
Thank you, bye.

Hi DaddyP,
thanks for you reply. Have tried as you suggested but unfortunately the crackling does not go away. But what I found out by trying that is that it seems not MacOS related because even unplugging them from the computers' USB port does not stop them crackling.
cheers.

USB headset's microphone starts to sizzle when used with my Mac Pro.

Hello,
First I would like to say I'm sorry for my english, I'll do my best but I'm not sure at all of what I'm writing.
Here is my problem: last year I bought a new Mac Pro 2.93 GHz Quad-Core, everything worked just fine except my headsets. I had a one year old Plantronics ".Audio 750 DSP Stereo Headset" that worked perfectly on my previous PowerMac G4 MDD.
When I used it to speak the microphone starts to sizzle after a random period of time (I just have to disconnect and replug the headset to make it works again for some time). I tried with every applications possible (Skype, Ventrilo, Teamspeak, WireTap to record myself and some others) and the problem always appeared.
I first though it was a coincidence and maybe my headset had a problem so I contacted Plantronics, explained the problem and they offered me to replace the headset with a new one but I had the exact same problem.
I tried with another headset (same model as mine) my brother had and this time it worked fine so I kept it for one year but some days ago it started to have some problem (not related to the mac) so I decided to get a new one, a Plantronics one again but a new model (Plantronics GameCom 777 Surround Sound Gaming Headset) and my problem is here again.
I searched on google, on many mac related forums and I didn't see this problem anywhere so I try here before sending back my headset and try another manufacturer.
The problem definitely comes from my mac but I don't know if that's a problem with all the "Mac Pro 2.93 Quad-Core" or just mine (as I said, except this problem everything works perfectely).
If you have any solutions I would be happy to hear them !
Thank you.

May have been good that you waited The better subject line might be, "What is the best recommendation for a Microphone Headset" or "Why does my Microphone Headset have noise".
After looking around a bit, and looking back over our posts, I've reached some conclusions that I would draw if I were you. I don't know if this addresses the totality of it, but this is what I think at this time.
The product: http://www.plantronics.com/northamerica/enUS/products/computer/console-gaming-headsets/gamecom-777
Now I know at least one application for this, and I can imagine a bunch more.
It's pretty expensive compared to one alternative I found that was the only device sold like it in this entire store, which I find odd: http://eshop.macsales.com/item/Altec%20Lansing/AHS602/
It looks to be of high quality and quite Apple ready;
The headset's surround sound hardware is built right into the included USB adapter, which plugs into any USB port on your PC or Mac with no additional software necessary. Simply plug the headset in to the USB adapter, and you're ready to go
So why won't it produce good sound?...
That the headset is just faulty perhaps. That the adaptor is faulty. But that's as far as I can think as far as the headset goes. There should be no other adapter that helps if the one they supply you does not. If it was an adapter problem it would only be their adapter problem, you don't need anything between that and your Mac. That device as it's set up is good to go. So the older adapter worked fine for 5 hours? That would point me to the current one they sent you as the problem. You'd have to ask them why one works well and the other does not (and if their phone or email support is a bad as their site support it, I feel sorry for you).
http://www.plantronics.com/northamerica/enUS/support/?WT.svl=leftnav
http://www.plantronics.com/europeunion/fr/?requestid=1207885
But say all is well there (you'd have to try another one they send you to see).
If what you have is fine, what else could it be.
This is all I can come up with:
1) Your USB ports on the Mac. Have you tried different ports?
2) Perhaps a long cable or something else concerning the headset (hmm, maybe not, something else in the Mac?), something that is still being affected by electrical interference. The different adapters you have... are they that much physically different?
3) An inherent problem on the 09 Mac Pros. They have one glaring problem Apple hasn't fixed yet regarding audio, that playing any raises the Macs temps to really high levels and degrades performance in apps when audio is playing in the background. For instance, playing a song in itunes. For many of us 09'ers our machines start to run really hot, really quickly.
Whether that has any impact on your issue I don't have a clue, and you'll get no help from Apple there..
So that, Igda, is all I can come up with. Those are the things I'd be mulling over right now.
I'd contact the company and tell them about your situation and particularly about the adapters. I'd ask if they have heard of any of their products having a problem on 09 Mac Pros.

XFCE USB Headset issue

XFCE has very annoying behavior with USB headsets.
If I plug it in and select the headset via the xfce mixer sound just continues to play though my speakers. the only way I've gotten it to play out of the headset is installing pulseaudio and pavucontrol, in pavucontrol I can go to the playback tab and select the mic per application and then it works, but this is a PIA. I have properly setup pulse audio as far as I know, with pulseaudio-alsa, alsa-plugins, and an asound.conf file.
I'd like it to play sound out of my headset in every application automatically when I select my headset in the mixer, and out of the speakers when I select the speakers, like gnome and kde do. Is there anyway to do this?
Thanks

Freaky, but you're right, it works. I was just in the middle of a garageband recording when my headset (Logitech, not sure on model) kept disappearing on me. I got a message saying it was disconnected when it was not, then it would come back only to have the same thing happen several seconds to minutes later. Finally it left and wouldn't come back. I rebooted thinking it was up too long (I've gone ninety days between reboots easily). No dice. So I found this.
Plugged it into a powered usb hub and it's back.
Very strange indeed. Have any advice on the SD card slot refusing to see the same card every few uses? lol I love my macbook pro but this weird stuff... it's just beyond me now!

Pulseaudio + USB headset: mic works, headphones don't

I have a Logitech USB headset that I've gotten to work under other distros, but not yet with Arch. I'm running ALSA + Pulseaudio, with my /etc/asound.conf sending ALSA events to Pulseaudio. This works fine for everything I've used, with the exception of my headset. The mic works, but I can't get get any sound through the headphones, it just always goes to the default sound card. When I run pavucontrol I can see my headset listed as an input device, but not an output device.
Any ideas? Been searching, but haven't found anything yet.

My headset is /dev/dsp1, just FYI

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.

DYNEX USB Headset no sound

Hello everyone,
I plugged in my DYNEX USB headset for the first time using ARCH linux, and I have no sound.
Things I did to try and make it work:
-It was recognized in alsamixer's sound card selection. I selected the card.
-I unmuted the master sound in alsa by using the command: amixer sset Master unmute.
-I used pavucontrol to select the headset
Anyone have any ideas why i am not getting any sound?

Better bouble check if it is unmuted and volume not 0 - not just "alsa master" like you did with amixer; it's probably best if you select the card in alsamixer (F6 or something) and check the channels. You can save those settings with "alsactl store".
Do you have sound if you select the headset for an application stream manually?
( p.E. start video in mplayer, look for it in pavucontrol under playback / applications, set its sink to the headset )
If that works the easiest way to get it working permanently might be:
- activate module-combine at the the TOP of /etc/pulse/default.pa MANUALLY (it tends to map channels wrong if you have more than 2; also that should ensure that the combine sink is always at the top, which can avoid some trouble).
e.g.
load-module module-combine channels=6 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe
( surround example; customize for your channels )
- delete the default / per application settings in ~/.pulse/* (in my experience those get rather useless in any case after a new sound device is added)
- make sure your combined sink is at the top with "pacmd list-sinks"
example:
$ pacmd list-sinks | head
4 sink(s) available.
* index: 0
name: <combined>
driver: <module-combine-sink.c>
flags: DECIBEL_VOLUME LATENCY
state: RUNNING
suspend cause:
priority: 1000
volume: front-left: 45864 / 70% / -9,30 dB, front-right: 45864 / 70% / -9,30 dB, rear-left: 45864 / 70% / -9,30 dB, rear-right: 45864 / 70% / -9,30 dB, front-center: 45864 / 70% / -9,30 dB, lfe: 45864 / 70% / -9,30 dB
- make it the default sink:
pacmd set-default-sink "combined"
You might have to "killall pulseaudio" before / in between steps to make sure it reloads settings / doesn't change them back etc.
Good luck!

Enabling USB Headset

I am using ALSA and have setup the sound for my system (using the Arch ALSA page).
Everything works when I plug my headphones into the Jacks.
I am no trying to enable my Logitech USB headset.
The usb_audio drivers are loaded and I have set the headset as the default device using both asoundconf and by putting this in my .asoundrc (from official ALSA guide):
defaults.ctl.card 1
defaults.pcm.card 1
defaults.timer.card 1
Both approaches result in nothing comes out of my headset. The volume is non-muted in alsamixer (for both my sound card and the usb headset).
aplay -l :

Is there something I'm missing here?

Edit:
I've messed around a little with asoundconf and I can get sound coming from my USB headset when I use 'aplay'. However, when I use mplayer the sound still comes out of the jack and not the USB headphone. Does asoundconf not set system wide defaults? If not, how can I set the system wide default for this machine?
Edit Again:
The -ao alsa option to mplayer did the trick.. e.g
$ mplayer -ao alsa /usr/share/sounds/alsa/Side_Left.wav
Edit Once More:
Sound only comes through the left channel. Oh no.
/em goes off to read .asoundrc documentation
edit.edit:
http://bbs.archlinux.org/viewtopic.php?id=51527
Seems related, but I don't know where to find the options mentioned in alsamixer.
Last edited by clanger (2010-01-11 16:45:00)

Yes, I tried Side_Right and it still comes out of the left channel. Flash and mplayer both still have this problem. As far as I can tell it effects every program using sound on the system.
Still not found a solution, don't really want to go down the OSS or Pulse route.

Plugged in USB headset and screen went blank

Last night I was playing Far Cry and the wife complained about the noise. So I plugged in a Logitech USB headset, and, ping! -- out goes the monitor.
All four LEDs on the MSI diagnostic bracket turned red. I unplugged the headset and rebooted--everything was fine. Any ideas?
Notes:
-I plugged headset into USB port on front of case, which is connected to one of the two internal 10-pin mobo ports (JUSB1 or JUSB2 I think).
-I have a 7-in-1 card reader plugged into the other 10-pin USB internal port.
Thanks,
RE

Thanks will try that. Also try using the other JUSB headed.
Funny-- the headset works fine when plugged into the USB port on the memory card reader...

USB Headset keeps frying on my T410

Hey all, So I've tried 3 different Logitech USB headsets and all 3 have been fried by my T410 ThinkPad. When I plug them in, they'll work beautifully when I have them plugged in for the first time, but when I try again, I'll start hearing weird buzzing, popping, clicking noises in the headset then poof, they no longer work and are rendered useless. This has happened 3 times now and I think my IT folks are upset with me! Is this a known issue? The Logitech headset is pretty standard/basic headset/mic combo fare. Super annoying. I want to order my own headset and not bug IT anymore but I'm afraid whatever headset I order will meet the same fate. Help!

Have you tried deactivating the "VOIP" button in Control Panel - "Smart Audio"? I needed to make that and it works well on T410 with Intel Graphics and Logitech 960 USB headset. (But the analog headsets still all worki very poor)
Also uncheck all other "audio enhancement" buttons in "Smart Audio" or "Sound" icons.

The mysterious crackling noise

Yes, this is another crackling noise post. But hopefully, it will be peculiar enough to capture your curiosity long enough to provide me with an answer
Like so many others, I get crackling noises on my recordings. However, this only started occuring after upgrading to Leopard and Logic 8 Pro (which, unfortunately, happened at the same time, so I'm not quite sure which of these might be the culprit).
I mainly record to my computer using an POD X3 Live, connected through an USB interface. I haven't been able to test recording with the POD to another machine that has Logic 8 and Leopard on it, but I know that the sound output from the POD is clean of any crackling noises.
Like any good Logic user is supposed to, I started changing my buffer size and buffer range to eliminate the crackling noises, though I really didn't like doing it. I've a reasonably powerful computer, after all, and should be able to use very small buffers. I WAS using very small buffers in Logic 7 under Tiger, far smaller than I can use now.
However, switching to larger buffer sizes didn't eliminate the crackling noises, only slightly reduced the frequency at which they appear. So, I'm drawing the conclusion that this is not related to my computer power, especially since my HD and CPU meters at the bottom of the Logic 8 never go above 5-10%, at the very most.
The only thing I've been able to connect to the crackling noises is that they appear with far greater frequency when I've used the computer for other stuff before recording without restarting. So, having played a game for a while or watched a movie will almost always ensure I get crackling noises unless I restart before using Logic 8 to record.
I'm even starting to wonder if the additional GB of RAM I installed at the same time as upgrading to Leopard and Logic 8 might be the cause. But I've had none of the other common problems normally connected to a bad RAM module (random shutdowns, etc).
So, does anyone have an idea about what might cause this? The POD? The USB connection? The RAM, Leopard, Logic 8, or my removal of the curve in the new transparent dock? A particularily bad taste in movies and computer games?

@twits celso: The interface I use is the POD X3 Live. It's a guitarboard/recording interface that is connected via USB.
But many thanks for your two suggested solutions. I'll be trying them both, and post the results!
@noeqplease: The POD is very compatible with Leopard. Line6 (the makers) had the new Leopard POD drivers up on their webpage a few hours after the release of Leopard. Give me a little more credit than trying to run an USB-connected audio interface/recording device with old drivers
However, it might very well be the drivers, but no other Leopard users on the Line6 forums have reported similar problems, which leads me to believe Logic might be involved in this, somehow...

The problem is that alsa (assuming that's what you use) doesn't do any card switching automatically - it decides on boot which card will be default, and sticks with that choice, even if the card is not available later on.
If you're using KDE or gnome, you can select the card used in their respective control centers (whatever they're called) - but that only affects programs that are using sound systems from these DEs. Also you can select which card to use in some programs themselves (like skype).
But, if you want to let alsa know which card to use, I think the config file for that is ~/.asoundrc
There's a python script which makes the management a bit easier (since the syntax is not very friendly) - asoundconf. Here's a thread where someone had a similar problem, and also there's a link where you can get the script: http://bbs.archlinux.org/viewtopic.php?id=39230
EDIT: by the way, I have a similar setup as you, and I didn't do any modprobe.conf modifications - the correct modules were loaded automatically.
