No input using USB Audio CODEX

We have been using the USB Audio CODEX input for several weeks from an Allen & Heath ZED 436 sound board. Suddenly last Sunday no audio inputs. It still sends to the computer but GB Will not record and no input levels show in the System Prefs. Any help will be greatly appreciated.

Hi
Firstly, sorry for not being able to help as I share the same problem.
I've recently bought a novation nio 2/4 audio interface for logic pro 8.
I have the same problem with getting sound from it. What are you trying to record e.g. instrument?
I also have a usb midi keyboard that I plugged straight in and got sound through logic straight away so I don't know why the audio interface should be much different.
Please let me know if you happen to stumble across an answer as it is driving me crazy!

Distorted recording with QuickTime 7 using USB Audio CODEC

I am running Mac OS X Tiger 10.4.8 with all the latest update from Software Update which includes QuickTime 7.1.3.
I am using QuickTime Broadcaster to stream back to itself (loopback) and record to disk at the same time. The input audio device is set to USB Audio CODEC (the default driver that comes with Mac OS X Tiger, and I am using an Alesis MultiMix 16USB mixer on a PowerMac Dual Core G5). I am using MPEG-4 Audio compression (no Video) of 16-bit, 44.1kHz and 128kbps (stereo).
The problem is that sometimes I get recordings (ranging from 1.5 hours to 2.75hours long) with distortion. Here is a short 20-second audio clip with distortion-free audio for about 6 seconds and then distortion sets in:
http://www.netmedia.com.sg/files/SampleDistortion20s.mov
Whether it overlays on top of the original audio or replaces it, I cannot tell, but the transition is instant and smooth with no audible clicks or pops. The distortion can come in and go randomly. For example, I had one recording with distortion coming in at about 2 minutes plus and it remained until about 2hr10min when the distortion went away. Sometimes it didn't go away; other times it came in about an hour later. I also had once where the distortion last only for about 6 minutes somewhere in the middle of a 2.25 hours recording...all in all, it occurs at random. And I do get distortion-free recordings.
This problem also occurs on an iMac G5 with a Alesis MultiMix 12USB mixer, and in another Vara Software's Videocue PRO software which uses QuickTime for recording and playback. QuickTime 7.0.x and all versions of 7.1 also had this problem.
Because of this problem, I may need to use a convoluted method to stream and record to disk via QuickTime. By the way, I also tried streaming to another local subnet IP address just as a troubleshooting without success.

I too am having distortion problem (Sorry no solution here).
Using OS 10.4.8, QT7.1.3, & Adobe Premiere 6.5 on a G4.
After I down loaded QT 7.1.3, my problems started. Is this when your problems started too?
Audio is in "slow motion" sound when editing. On rare occations, it sounds correct for 10 sec or so but sync is out and eventually reverts to "slow motion" sound. Even more bazar, when viewing a clip in a thumbnail preview, it works fine. So I know the orginal is good.
My contention is QT is causing this. All I want is my previous version of QT back. I think this might fix your problem too. Unfortunately, there is no reinstall that I can find that takes QT 7.1.3 off and puts QT 7.1.1or2. The reinstall QT 7.0.3 which is on the Apple website will not restall.
Looking for a reintall that will take QT 7.1.3 off, help anyone?

Distorted recording with QuickTime using USB Audio CODEC

I am running Mac OS X Tiger 10.4.6 with all the latest update from Software Update which includes QuickTime 7.1.1.
I am using QuickTime Broadcaster to stream back to itself (loopback) and record to disk at the same time. The input audio device is set to USB Audio CODEC (the default driver that comes with Mac OS X Tiger, and I am using an Alesis MultiMix 16USB mixer on a PowerMac Dual Core G5).

The problem is that I usually get recordings (ranging from 1.5 hours to 2.75hours long) with distortion. The distortion sounds like audio going through Logic Pro's BitCrusher plug-in, that is, audio recorded with less than 8-bit resolution but kept at 44.1kHz sample rate. Whether it overlays on top of the original audio or replaces it, I cannot tell, but the transition is instant and smooth with no audible clicks or pops. The distortion can come in and go randomly. For example, I had one recording with distortion coming in at about 2 minutes plus and it remained until about 2hr10min when the distortion went away.

Using USB Audio surround speakers with iTunes (they don't work)

My HP USB Audio surround sound speakers (which are brand new) do not work with iTunes; however, they do function because they work with Windows Media Player.
Can someone assist me to get them working along with the built-in speakers on the laptop?
Thank you.
HP Pavilion dv9000 Windows Vista laptop

anyone?

After sleep, audio turned on when using USB-Audio!

It seems that after the EFI update, the external USB Audio device is also on after standby and not muted as before!
I have a C-Media USB Headphone set (this means external speakers over an USB), normally muted.
After sleep it is unmuted and at full volume. (When i let it with low volume, after standby it is also at full, but the bars are displaying it as low).
Anyone same experience?

UPDATE:
I decided to try going through an Firewire Audio Interface instead. Keyboard-(MIDI)->MOTU Traveler-(Firewire)->MacBook Pro.
Same corruption/hiccups/choppy playback.

Getting Midi input using USB connector

I have a keyboard hooked up to my mac using a Midi-USB connector, and in Logic although I can set it up to output midi through the keyboard, I don't know how to get it to accept input from the keyboard, it constantly says "No In" even when playing notes.
Does anyone know what I need to do?
Thanks

Crackling/popping/garbled when using USB audio iPod iOS 6.16

I know several people are having this issue. iPod touch with iOS 6.16, when using the USB cable plugged in to Ford Sync or other stereo head units with USB connectivity, I hear a random popping/crackling/garbled sound. The iPod does this on 2 different vehicles so I know it is not the stereo it self. I have a 2005 Chevy Silverado that I added the IS-GM655 adapter to install a USB and AUX port. Also I have a Ford Van that has the SYNC system in it.
When the iPod is plugged in to the stereo via the USB port, I get random popping or crackling like a CD skipping from the audio. When the iPod is connected via the AUX headphone jack, I don't seem to hear any popping or crackling. I have tried cleaning the port on the bottom of the iPod with rubbing alcohol and it seemed to help a little, but I still noticed the popping/crackling/garbled sound coming from the USB connectivity. Also, Bluetooth and WI-FI are off, I even tried airplane mode and different USB cables, still get same symptoms.
Any fixes for this yet, it appears from all of the other threads I have read and googled, there are SEVERAL other people experiencing this issue and nothing has fixed it??
The only thing I use the iPod for is music, there are no other apps installed on it currently.

Hey Relentless85, Have you tried a "Cline Free" dryer sheet? ! OK, done messing around. It's static electricity, why I have no idea. In my Toyota, I have this issue, The other half's Toyota-- no issue! (go figure) It's always worse in the winter, and only with one adapter. As long as you don't touch the iPod, move it or look at it for to long, your OK. But do any one of the listed activities, you know use the iPod-- it clicks and pops likes a bowl of Rice Crispy's. This helped me, it's going to sound stupid and shouldn't work but it does help. Get yourself a grounding tether, the wrist strap with the wire, the thing you wear when working on computer's, anyway place the strap on your iPod, so it touches the metal back, and the other end attach to some part of your vehicles frame, not to any of the wiring! It shouldn't work but it does for me. The garbled sound, does it it sound like the feedback noise from cassette tapes? (Maybe your not old enough for that...) or over metered sound? A distortion or rumble? Try turning off the EQ feature on your iPod or put it on FLAT, or reduce the volume output level from your iPod to about 80% - 85%. It could be the iPod is sending a frequency that exceeds your car stereo's range, (over metering. On analog tape you did this to boast the bass, but the same practice in digital format causes distortions). About the only other thing to try is Resetting or Restoring, but I don't think it will help in this case. If the tether ground helps, it static, if not-- then you cleared out one thing to check. Hope this helps, Good luck. Cheers.

USB Audio CODEC replacement sw

hello all,
As it is demonstrated in the thread http://discussions.apple.com/thread.jspa?threadID=1129950&start=0&tstart=0 in the GarageBand discussion section, many users experience an intolerable static when using USB Audio CODEC for sound input. This was not the case in earlier versions and the consensus in that thread seems to be that something happened in OSX 10.4.11 that broke the codec. Since who knows when this will be fixed, I am wondering if anyone knows a source for an alternative, e.g. from some Linux source etc. I have been using an old Cube and I have no other way to get sound in but thru the USB port (methinks, or is there? FW?)
Thanks

But this mic is for Mac too. It's says that you "plug and play". I bought this microphone to record my music work at home.
This is the website, It says that works fine with Garage Band but ...

Recording noise using USB turntable

I'm getting intermittent distortion/staticy noise at times when trying to record my LP's using "Audacity" software (1.2.5 for Intel Mac) and an audio-technica AT-LP2D USB Turntable. It is random, and comes out of nowhere at any time when recording. Once it starts, it persists. I've been able to complete several LP recordings, but it's very frustrating. I have to abandon the recording and start over if the noise starts up.
I've changed the USB cable, used a different USB 2.0 port on the back of my iMac, reinstalled the "Audacity" software, and reinstalled the stylus assembly - nothing eliminates the noise.
The below is a quote from audio-technica Repair/Support when I asked them about this noise problem:
"...there is a known problem with certain Mac computers experiencing "distortion" when using USB audio devices. This problem is not exclusive to our product, and has been documented online by several USB audio device users. I believe this to be a USB audio driver issue. I highly recommend contacting the folks at Apple about this issue."
I've not been able find anything in Apple Discussions or Audacity Forum that point to any inherent problem with either the iMac hardware or the USB turntable. The very random nature of the noise problem would indicate a defect in the turntable USB circuitry. I might add that when I'm monitoring noise (on my iMac while recording using "Audacity"), there is NO NOISE monitored at a clock radio connected to the turntable (turntable "LINE" output to "AUX" input of the clock/radio).
Has anyone heard of this problem? Any suggestions?

Be sure to try disconnecting all other USB devices (such as hard drives and printers) while doing the recording. All devices except for your standard mouse and keyboard, that is. Since they all connect to the same USB bus, there may be some interference.
Alternately, you can connect the line output of the turntable to the audio input of the iMac (using an adapter for RCA to mini-stereo jack), and not use the USB connection. You can monitor the sound while recording with the play-through setting in your recording software, or by running this simple program called LineIn.

Multiple USB Audio Outputs?

Is it possible to set up the mac mini to have multiple USB audio out puts? I'm wanting to use a mini displayport + usb audio > hdmi cable to a plasma for computer use. But is I want to listen to just plain music use USB audio to a DAC into a 2 channel system. So for this system I would need to use 2 USB outputs for music.
Thanks

Sure,
You can output sound through more than one little external USB sound card, but probably not to more than one at a time. You'll have to select the Output in the Sound Preferences each time to switch them, too.
But don't overlook the Mini's internal sound output as one of your 2-channel or 5.1 audio outputs. The 2009 Mini has better audio output than the PPC Mini, that I also had and used an external USB sound card with (M-Audio Transit). Of course, now there are cheap little external USB sound cards that look like a little thumb drive for an added 2-channel audio output. So, I'd use the Mini's internal output and an Optical cable for 5.1 sound out, if I were going to use one of those cheap little sound cards. But you can go the other way, too, if you want, with a better USB dongle (like the M-Audio Transit) for your 5.1 sound.
Please let us all hear how it goes and what path works for your application.
Peace to you,

Iphone 4s usb audio crackling and popping

hi my iphone 4s crackles and pops when listening to music using usb audio playback in my car
my ipod is fine just the phone that does it
anyone know of a fix ??

The system in your car is probably not designed for use with an iPhone. The radios in the iPhone can put out quite a bit of interference. If the system is not designed for it, this can result in very poor audio quality. Try putting the phone in airplane mode and see if the problem persists. If it goes away, then it's a compatibility issue with your head unit.

Still fighting the problem altho have heard audio a few times. Had audio but no video!
Using usb audio.
Don't know the name of the intel audio device for loading into modules of rc.conf. Perhaps that is the problem.
Also don't have control of pcm setting in alsamixer, master is OK.
USB mixer uses "front pcm".
Info in mobo manual says "realtek ALC662 codec" EDIT

USB AUDIO CODEC PROBLEMS

A few days ago I bought an USB Microphone (Samson G-Track). I don't know why It doesn't work. When I select in Sound/Preferences/Input the "Usb Audio Codec" but It says that there aren't input controls in the device. I tested it at Garage Band but It didn't work. I thought that the mic was defective but when I tested it in my mother's pc (Vista) It worked.

Thank you.

Hi Rhea91-
Your English is indeed very good
Are you plugging the Mic directly into a USB port on your Mac? Are you certain there are no Mac-specific drivers? "Mac compatible" can mean many things. Is the device OSX 10.5.2 compatible?
