Strange audio produced when Dynex USB Headset is combined with Realtek ALC888

t seems that just when I connected my Xbox 360 pc controller, my Dynex USB Headset began acting up.
Whenever I use the microphone function, the audio comes out as though I was talking through a Nintendo Entertainment System (8 bit-ish sound), no matter what I play the sound through. (So it sounds the same, whether I play it through my Creative desktop speakers or through my headset.)
I've tried almost every kind of troubleshooting technique I could think of.
Removing the drivers then installing older ones worked for awhile, then began acting up again.
I tried rebooting (of course), that didn't fix it.
Updating sound drivers; nada.
I recall disabling the sound chip through my BIOS, booting, rebooting, enabling it, then booting, although that only fixed it temporarily. I've tried the headset in another computer with the same OS, and it worked fine, so I don't think it's the microphone.
I've tried shutting down as many electronics as I could (cellphone, air purifier, xbox controller, unnecessary monitors, wireless mice, even lights), although nothing could fix the odd sounds.
Later, when I was completely cleaning off the Realtek drivers once again, I decided to just listen to sound trough my headset's earpiece. Everything had 8-bit sounds. Even music files, which originally played normally through my desktop speakers. However, I think my headset it still functioning ok from a hardware perspective, since I plugged it into my other XP machine, and it still worked fine.
Computer specs:
* MSI P6NGM-FD motherboard
* Windows XP SP3
* Realtek drivers, updated to R256
* Dynex USB Mon Headset
Also, here's a small soundclip of me saying hello, then blowing on the microphone.

If anyone can help, that would be great.

I am trying to use a Logitech USB headset to record with screencast o matic. In the sound file of system preferences the headset is recording audio. However it stops working when I use screen cast o matic. Any advice?

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!

[SOLVED] Switch all audio input/output to USB headset

Hi, I have a USB headset that I frequently plug/unplug from the computer. Is there a way to make it the default sound device when plugged, and automatically switch back to the motherboard's on-board audio device when unplugged?

I have an Intel HDA 5.1 internal audio card, and a 5.1 USB headset, using the modules snd_hda_intel and snd_usb_audio respectively. The internal card is set as card 0, and the usb headset is set as card 1.
I'm using ALSA right now, but I wouldn't have a problem switching to Pulseaudio if it's easier.
EDIT: I used pulseaudio and solved it for applications that are not already playing sound (not shown on pavucontrol's Playback tab)
I created a udev rule, which executes a script when card1 is inserted, since I know it is the USB sound device:
SUBSYSTEM=="sound", KERNEL=="card1", ACTION=="change", RUN+="/home/stavros/bin/pulse-ins.sh"
This script (pulse-ins.sh) executes another script as the current user:
#!/bin/bash
su -c "/home/stavros/bin/pulse_insert_card.sh & exit" stavros
pulse_insert_card.sh contains the following:
#!/bin/bash
/usr/bin/pacmd set-default-sink alsa_output.usb-0d8c_USB_Sound_Device-00-Device.analog-surround-51
/usr/bin/pacmd set-default-source alsa_input.usb-0d8c_USB_Sound_Device-00-Device.analog-stereo
These 2 scripts and the udev rule automatically change pulseaudio's default output & mic input when the card is inserted. However, applications already playing music have to be switched manually through pavucontrol.
Sometimes, the card is incorrectly identified as "Analog Stereo Duplex", with no 5.1 option. In that case killing pulseaudio and letting it start again solves the problem.

Strange audio issue when running render queue via script.

The issue I'm having with AE is odd, and I'm hoping someone may be able to shed light on the matter. I have a very simple composition that, when I render out using the GUI, everything works as expected. The video renders fine, the audio renders fine, etc. However, when I invoke a script that runs the .aep file, sets the render queue for the composition in question, and then renders it, only the video comes through, but no audio. There is nothing in my script prior to the setting up of the render queue that alters any audio layers (i.e. no code shutting off audio, etc.) Has anybody ever encountered this? The audio file is a .wav in 44.1KHz, 16bit, stereo, and will try other formats to see if the problem might with the file itself? Although, I don't see how that would be the case if it is rendering just fine via the GUI.
Any help you can offer for troubleshooting would be great! Thanks for your help and time!

Thanks for your suggestion. It wasn't the output module. I created a custom template for it and ensured the audio was checked. It was an odd fix. I deleted the audio layer, then dragged it back to the timline. Then, it worked. Cost me like two hours of work for that, and I should have checked it earlier. But I still don't know why the original wasn't working.

I lost audio output except for USB headset any Ideas?

Has anyone experienced the loss of audio output except for the USB port? If so what might I try to fix the problem?

Strange PDC issue when inserting compressor on a group with side chain

Hi Forum People!
Seem to have hit a brick wall trouble shooting this issue, and hope someone here can help.
Whenever I insert a compressor on a bus, and send a sidechain trigger to the compressor, PDC stops working for all multi-output synths. I can sidechain stereo tracks without an issue, but not group tracks with mutliple tracks routed through the groups.
For the record, as soon as I remove the send to the sidechain, PDC works normally.
Is this a limitation of Logic's PDC, or is there a workaround that I haven't discovered?
Many thanks for your time
Steve

LOL! Sorry, didn't have time to respond yesterday. The problem was the way in which I'd set-up the group. Here's how I had the group set up, which broke PDC:
I created an auxiliary track (the group), inserted a compressor, and routed my drums direct to this group.
Here's how I fixed the problem:
instead of creating an aux channel for the group, I routed my drum outputs through an unused bus, which in turn created the group channel automatically.
I've only been using Logic for 1 month, having used Cubase for nearly 20 years, so realizing some things are done very differently.
Thanks chaps!

Hi Michiel,
You'll need to move $params and New-ADUser up into the foreach loop.
EDIT: Also, remove the { $ User } that you have next to the foreach loop. You're also using $Users instead of $UserList.
EDIT2: Here's a cleaned up version:
$UserList = Import-Csv -Delimiter ";" -Path "......csv"
FOREACH ($User in $UserList) {
$OU = $User.path
$UPN = $User.UPN
$Password = $User.password
$Detailedname = $User.firstname + " " + $User.Lastname
$UserFirstname = $User.Firstname
$FirstLetterFirstname = $UserFirstname.substring(0,1)
$SAM = $User.UPN
$Company = $User.company
$Description = $User.description
$AccountExpirationDate = $User.accountexpirationdate

Ventrillo and USB headset issue

I recently purchased a USB headset to use with ventrillo (voice-chat software). While it is a definite upgrade over the built in mic, my friends are telling me that it is also producing a noticeable buzzing sound when I speak, which seems to increase and decrease randomly. I'm told sometimes its not too bad, and sometimes they can't hear me at all over the buzzing, which happens with no changes to the mic output. I think this buzzing problem may be caused by the external keyboard that I use, but am not sure.

You can very easily test your theory by disconnecting the external keyboard and using the built-in keyboard instead, and seeing whether the buzz goes away.

Logitech USB headset

We had a logitech USB headset for Dragon and it all worked fine.
Headset wires broke and so I replaced it with the closest one I could find (ML-341) to what we had.
So let's forget Dragon and just look at the MacBook Air.
When I am in System Preferences -> Sound it recognizes
a) the internal microphone,
b) the USB headset that came with Dragon (USB Ear - Microphone) and
c) the USB Logitech headset (Logitech USB Headset)
BUT as I switch amng all three in SOUNDS the Logtech doesn't work. (no blue input levels moving)
Volume is up and mute is off.
I don't have to box but I am certain it is a Mac compatible Logitech as that is what I went to buy.
I have looked at the utility MDDI? but don't see anything I should be changing there either.
What's up?
S

Hi
I have the Logitech Headset Premium Stereo 350 USB. Since the 10.4.6 upgrade (I think) it has not been working as it should, but it does still work. You need to go into System Preference > Sound > Output, have the headset selected as the output device, and then click the mute button on and off. Have the headset on while you do this and play with the volume control at the same time so you will hear when the sound does start to come from the headset. I have no idea why Logitech have not sorted this problem out yet, but the headset does work fine if you are prepared to fiddle around every time you use it.
While we are here I want to recommend SoundSource for quickly changing audio inputs and outputs. It doesn't help much with the current problem, however.
Edit: BTW on my headset, the flashing blue light is the mute indicator for the microphone. Pressing the centre button toggles it on and off.

USB headset / Jabra 6470 question

I've just made the transition from the dark side, and I have a question about getting a Jabra 6470 working with OSX. I think it may be a limitation of my understanding of how audio devices are treated under OSX.
The Jabra can connect either via USB or Bluetooth. Under Windows, there is a driver and client software for the Jabra. There is none for the Mac. When I connect the Jabra to the Mac via USB, it shows up as an audio device in Control Center and appears to be available from Skype, but I can't actually get it to work. There's no audio, and the microphone doesn't respond. If I connec the Jabra to the Mac via Bluetooth, I can get both the audio and the microphone to work fine... but it appears that ALL Mac audio is redirected. It looks like it's all or nothing... either everything goes through Bluetooth or nothing does. Ideally I'd like to be able to let Skype use the Jabra but the rest of the Mac use the built-in speakers and microphone.
Is this the way it is supposed to work (all or nothing) with a bluetooth device? And any hints on getting the Jabra to work USB?
System info:
iMac 27" 3.4Ghz i7, 768GB SSD, 32GB RAM, OSX 10.8.2... also has a secondary 27" display and a Drobo 5D, but I doubt if either of those are part of the equation.

usb is a digital serial interface it can never carry normal audio
which is why usb headsets are not just headsets they are audio cards which connects over usb
and to do that you need a driver
about bluetooth all or nothing then thats the same with all windows not just osx if bluetooth headset is used all other audio outputs are muted
would assume the same to be the case if you find a usb driver for the headset

USB Headset Woes

Greetings!
I have a Logitec USB Headset and I am having problems with programs seemingly wanting to continue outputting to the USB headset even after it's unplugged. Here's a typical synario:
I wanted to do some voice recording of a book, I plugin my headset, change the Audio/MIDI preferences in Garage Band to indicate my Input and Output device is the "Logitec USB Headset". This works great, records great, plays back. I then call my wife in to hear my latest creation, and go back to the preferences and select "Built-in audio" for the output. Garage band asks, "Change audio driver?" Yes, I choose. A few seconds later, the Output device is set to, "Logitec USB Headset" and there is no longer any choice what-so-ever for an input device. I can again choose "Built-in Audio" for the output device, it goes through the same sequence, only to arrive at the same result.
It get's weirder as well. I say, OK, I'll fix it, I unplug my USB headset. Still same problem. I then restart Garage Band and now the preferences dialog will not even open! Ok. So now, I remove ~/Library/Preferences/com.apple.garage* and also ~/Library/Application Support/GarageBand thinking it might have saved settings. Still, no go.
Now, the reason I am not posting in the Garage Band forum is because this has happened in other applications as well, mainly, QuickTime. I wanted to watch a movie late at night and plugged in my headset, set the system preferences output audio device to "Logitech USB Headset" and watched a movie in QuickTime. Now, from that day on (2 weeks), QuickTime, no matter what, no matter how many restarts, removing of configs, etc... will not play to anything but my headset. If my headset is not plugged in, I simply get no audio. Other apps, such as Adium playing system beeps, speaking voice, etc... work just fine through the built in speaker. So far, the two affected programs are QuickTime and GarageBand. I have not been willing to see if it happens with iMovie and iDVD yet, in fear the same thing will happen.
Anyone have an idea?
Mac Mini, 1.42ghz, 80g hd, 1g memory, super drive, Mac OS X 10.4.5, etc...

This is a brand new install of Mac OS X also. I wanted the experience of installing Mac OS X, so I backed up my important data, formatted the drive, installed, no other apps what so ever, and this happens. Oh, I did do the software updates and am on all the latest software packages as of the first time they were ever run. My install procedure was, install Mac OS X, Update, Install iLife, Update. A quick check today shows everything is up to date as well.
Thanks!
Jeremy

I have purchased a firewire drive and reinstalled Mac OS X on it, and still have the same problem. I did not migrate any previous settings, and right after install, I did a system update, then right into one of the programs mentioned. The problem occured with both QuickTime and GarageBand.

MacBook Air: automatic selection of USB headsets for sound output

Is there a way to let the MacBook Air automatically detect an external USB headset,
and switch from internal speakers to the USB headset, and reverse to speakers when the
USB headset is disconnected ?
It's nice that you can manually select the output in System Preferences / Sound,
but it would be nice also to be able to make the computer use the USB headset
whenever it's plugged in.
Same for the microphone (sound input selection, for USB headsets with a microphone).

USB hub works fine on my 23 Cinema display with the Air, haven't tried the others but I use the USB on display to plug in my mobile broadband ( live out in the sticks and don't get cable or DSL ) and it lets me switch between my Air and MB Pro fine.

Audio problem when burning DVD

Hi, Hope that someone can help me, I have already make several DVD's,and those went fine, but the latest Imovie project is with spoken audio.
When I try to burn this with IDVD 5.0.1 everything went well till IDVD has come to the audio part, hereby it goes wrong. I didn't get a failure message but nothing happened further on.
Hope someone has a solution!
G5 Mac OS X (10.4.3) 2x1.8 ghz

Hello, prutgers,
You will need to be a bit more specific with your problem so we can help you.
What do you mean by 'it goes wrong'? What exactly happens?
You need to know that when your DVD is encoding audio, the process appears to be doing nothing. If you leave it alone for a while, it just may finish. Maybe you are not waiting long enough.
Especially if you don't get an error message. What are you doing? Did you force quit? Did the DVD burn and has an audio problem?
Give us more information!
