IBook G4 - Seeking Compatible USB Microphone

Both of our iBook G4 (1.33 and 1.42 GHz) computers have dead internal microphones (located on right side of LCD panel). I'm hesitant to take the time to replace them, due to risk of damage to other components. As many of you know, there is no audio input jack on the iBook G4; only audio output.
We've been looking at various external USB microphones that are totally encapsulated within the USB stick. We found one out there that could do the job, but we are wondering if there is something else out there that could serve as another option. All we want to be able to do is set up audio for Skype on the 1.33 GHz machine, for now.
We believe that the USB ports are USB 1.0 and are not powered (i.e., 2.0) but could be wrong.
Advice would be greatly appreciated.
Here's the link to the only compact USB microphone stick we were able to find, by the Sound Professionals:

Thanks in advance!

I am pretty sure that the USB ports on your computer would be 2.0, but I think you can test this. Try plugging in a USB storage device (Made fairly recently). Then go to the Apple Menu, and click About This Mac. Then click More Info. When System profiler opens, click down the Triangle next to hardware and select USB. You probably have 2.0 if under the device you plugged in it says up to 480mbs per second. You should have USB 2.0, because my iBook G4 is older than yours and it has USB 2.
For Skype, I would think that any microphone for Mac OS X should work. Not sure, but it would be my best guess.
Hope that at least helped!

Using USB microphone with iBook

I have an iBook G4 and GarageBand 1.1. I recently bought a MicFlex USB microphone, but I can't make it record. I have set the system preferences and I can set the record level for the USB mic there, but GarageBand automatically uses the built-in microphone for recording. How do I change this?

No worries, now you're a little less new. Enjoy --Hang

Compatible USB Ethernet Adapter

I am looking for an adapter that will work with my iBook G4 as the network port is broken.
Does anybody know of compatible USB Ethernet Adapters?
Thanks a lot.

Well, given the title of this topic, what's the problem? As for "high speed" - even old 10-T would saturate the vast majority of broadband connections, and anything is better than no connection at all.
To reiterate, wifi is not much use if you're somewhere with only wired access (and my wifi works just fine in other locations), and if you happen to have blown up your ethernet port, USB ethernet is a reasonable route. Just cross your fingers that you don't trip over it again...
Incidentally, Mac USB wifi drivers are available for some chipsets - this is worth a read: http://www.macosxhints.com/article.php?story=20050201091946184

Help with USB Microphone Issues

Checked the support area about USB Mics but am still having trouble.
I am running Soundbooth stand alone, on my Mac Book..Leopard OS. I have a Samson Co3U USB microphone with a Samson Soft PreAmp loaded. I am switching over from Garageband to Soundbooth. I have actually used Soundbooth once and it worked fine..until this week. I'm not sure what I am doing wrong now. Probably need lessons. The Midi set up is set to System default Input/Output which is actually set to the Samson mic, but when I record, all I get is a very muffled audio. I know its not the mic because it still works great on my other MacBook in Garageband.
I also wonder whether Soundbooth is just not compatible with Garageband on the same Mac.
Any ideas?
Thanks in advance.
Heather

Hi Heather,
Soundbooth and GarageBand can exist side-by-side with no troubles. In fact, many GarageBand users use Soundbooth to edit their loops and clips, and to clean up and trim their GB projects.
The Samson USB mics are very nice and should work well with Soundbooth. Along with the Blue microphones, the Samson series are the other higher-end USB microphones that I use for testing.
As a quick test, and to make certain we don't affect any other applications, let's try making a customized Aggregate Audio device for Soundbooth using the Samson mic.
* Close Soundbooth. Open Finder and click Applications > Utilities > Audio MIDI Setup.
* Click the AUDIO DEVICES button at the top then in the menu bar select Audio > Open Aggregate Device Editor
* Click the [+] button to create a new aggregate device. Name it SOUNDBOOTH DEVICE and select the Built-in Output and Samson C03U devices from the bottom list. Click Done and close the Audio MIDI setup tool.
* Launch Soundbooth, then open Preferences > Audio Hardware. Change the Default Device dropdown to the new SOUNDBOOTH DEVICE we created, then click OK.
* Try recording!
This driver setup should force Soundbooth to use the Samson device for input, and nothing else. IF you still experience the muffled audio or other recording problems, please reply with more information and we can continue troubleshooting.
Thanks,
Durin

Logitech USB microphone does not work with OS 10.4.11

My logitech USB microphone was working fine, at one time. Now it does not function. In the sound prefs setup, it shows a level reading, as if it is hearing the input, but there is no output. I have tried every setting I could find in Audio Midi Setup as well, and nothing seems to work, and the "thru" option is not available. Can somebody help me here?

Hi stuntmedia, and a warm welcome to the forums!
See if it's the Mute button first...

Blue Yeti USB microphone not working in ALSA/PulseAudio

Hi all,
I recently bought a Blue Yeti USB microphone. It is supposed to require no drivers for Windows and OS X, and so far, it works well under Windows, but I cannot seem to get it to function on Arch Linux. As fair warning, although I am relatively experienced with Linux, I don't know much about the internals of ALSA/PA --- up until now, it has just "always worked", so this is my first real foray into the area. I've tried for many days, with no success, to get this thing working.
So, let's start off first with my configuration.
I have a few audio devices:
An on-board audio solution that I don't typically use. For testing, I have connected an old, crappy pair of headphones, but normally I keep this disabled. It has one capture device. (Analog stereo [or 5.1/7.1/etc] duplex)
An external DAC that is connected via USB and is output-only. So, no capture devices on that. (Digital/IEC958 output)
The Blue Yeti itself, which is connected via USB and supports output (it has an internal DAC) as well as input. So, one capture device here. (Digital stereo output and analog stereo input???)
The HDMI-out stuff for nvidia, which I never use
Here is the output of "arecord -l":

If the output of "aplay -L" is needed, let me know, but it's not all that different from arecord -L.
Here is my /etc/asound.conf:

I don't remember where the bulk of that came from; maybe it was installed like that or maybe I put it in there. Here is another useful command showing non-commented-out/non-blank lines in the pulseaudio conf:
$ egrep -v '^;|^#|^$' /etc/pulse/*.conf

Honestly, I think that's about all of the configuration info I can give. Here are some screenshots of pavucontrol, though, in case you are not yet sated: http://imgur.com/a/ngyLl
Now, on to the debugging stuff. First: everything except Blue Yeti recording works. The external DAC works, the on-board audio (both input and output) work, using the DAC in the Blue Yeti to play music/monitor the microphone works (so it works as an output). The only thing that doesn't work is actual recording from the Blue Yeti itself.
When I try to record from the Blue Yeti with parecord -v, I get very strange behavior. Essentially, the "latency" of the microphone measured is exactly the same as the time it has been recording. That is, if it has been recording for 5 sec, then the latency is 5000000 usec. Also, if I try to record something in Audacity, I get no result except for a message box that says "Latency Correction has caused the recorded audio to be hidden before zero. Audacity has brought it back to start at zero." Also, pavucontrol doesn't show an input volume bar for the Blue Yeti, as in the above screenshots, whereas it normally will for microphones that are getting input. The Yeti is not muted, either, so it should be picking up ambient fan noise and such.
Does anyone have any ideas? Is there some configuration error I've made? Typically, this sort of stuff simply works out of the box for me, so I am somewhat stuck on what to do. Could it be a driver-level bug?

I'm not sure what you mean by "mixed with audio in Alsamixer". Can you clarify?
With that said, my problem did mysteriously fix itself after some update (presumably to alsa). Unfortunately, I noticed it in passing one day while I was changing the volume of something in pavucontrol, so I don't remember the exact update that caused it to work. But yes, my current setup does work now: I can listen to audio through my DAC and use the Yeti for recording. However, I have found that use of the Yeti crashes Google Hangouts, although it works perfectly in every other program I've tried.
As documentation, here is my current working setup (it is very similar to the above): in PulseAudio, the DAC is set to be a Digital Stereo (IEC958) output. The Yeti (called an 'Integrated Rate Matching Hub' in pavucontrol) is set to be an Analog Stereo Input. In the input devices section, I have the Yeti's volume set to around 58% (-14.31 dB), which is past the base volume a fair ways but produces decent levels for recording. The DAC's volume is set to 100% (0dB gain, the DAC takes care of the level). In alsamixer, I have the mic level for the Yeti set to 40.
Edit: This is a long-time-later edit, but let me say that when you have multiple USB audio devices, what USB hub and in what order they are connected seems to matter a great deal. If you can't get your Blue Yeti to work, try moving it to a different set of USB ports (controlled by a different controller) on your motherboard. This magically fixes the issue for me.

Is there a known problem with USB microphones?

Background
OS X 10.5.8
Premiere Elements 9
Hardware Intel iMac
I use a USB mic with all my audio applications.
However, it appears that PrE doesn't see the mic for narration. I've set up the audio hardware preferences to use the Default System Input/Output but no recognition of the mic.
The mic works fine on all my other applications and is selected in system preferences to be the input of choice, and tests indicate it is recognized.
I changed the audio hardware selection in PrE to use the built in mic and it works as expected.
So I'm led to wonder if there is a problem with using a USB mic?
The documentation, referencing windows only, mentions plugging in a microphone to the microphone socket on the PC, not mention of a USB mic?
Any pointers to where I might find a solution?
Thanks

Thanks Neale, in particular for posting the images:

To use my USB microphone (built in to my webcam) I go to Preferences> Audio Hardware and select "Premiere Elements Windows Sound" as the Default Device.
Then click ASIO settings and ensure your microphone is selected.
I believe I'm making a similar selection
I've tried all the selections. The built in system works but my external mic, when selected in system preferences as the default, is not recognized.

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. I need all three for a podcast, any solutions?

I have three Blue Yeti USB Microphones, and when I try to create an aggregate device in Audio MIDI on my MBP it lets me select two microphones but not the third. At first I thought maybe the third microphone was just defected or something but I tested the mic individually and it works fine. It'll let me use two Blue Yeti's and another microphone but not three Yeti's at once.

The problem is that the mac chokes on having 2 identical mics attached at the same time.
Ive had 2 identical USB AT2020 mics connected at the same time on both macbook pro and macbook Air.
The "Yeti" mics, are, lets say undesirable, and low to mid computer consumer mics.

Using USB Microphone With GarageBand iPad?

Hi, I have the Samson G-Track USB Microphone and have been using it with GarageBand for iPad (with a powered USB hub) and I was wondering if there is a way to enable "Monitor" so that when I speak into the microphone I can hear myself in the headphones? I have no problem recording with the microphone, I just can't hear myself when I'm recording. There are a few switches on the actual microphone that could control this or it could all be controlled from iPad itself, just looking for anyone who could help with this matter. Thanks!

I'm having the same problem trying to monitor my turntable recording via a USB phono amp connected via a USB hub to the photo connection kit.
Have you had any help with this yet?

Replacing the hard disk on an iBook G3 (700 Dual USB)

Hi
I'm kind of regarded as the guy to go and see when anything goes wrong with a Mac, here in Athens, Greece. But I have very little hardware experience with laptops. A friend of mine just brought me her iBook G3 (700 Dual USB), running Panther 10.3.9 to check out. She was getting the initial start up screen (grey Apple, spinning wheel) and once in every ten times or more actually getting into her hard disk. Anyway after a bunch of tests I narrowed the problem down to the hard disk (40 gig, I think). The disc is basically presenting all the symptoms of a damaged disc. I can not even wipe and reinstall on it. When I start up from the Panther system CD, it runs normally, up to the point where I tell it to install, it goes to the next screen where you choose your destination disc, and shows, nothing! Disk Utility on the install disc sees the hard disk and identifies it as an IBM, but the single partition with Panther installed is greyed out. I tells me that the disk can't be wiped because of an ERROR -20. I also tried mounting it on my G4 as a firewire external, and in fact managed to rescue the data, (though it took an hour to transfer 250 kb of data). I even tried to wipe it in my own machine as an external disc, but again the same problem. Strangely enough Disk Utility says the disc does not need repair.
Anyway, I decided to change the disk and be done with it. But as I say I have very little hardware experience with laptops, and the Apple support pages don't have any documents that show the internal workings of the iBook, except for how to change memory and install Airport cards. Aside from the fact that I still have to figure out where to find a new disc for the machine, I don't really want to open it up until I can check some instructions.
Can anyone give me a clue how you get inside these machines? I have a Powerbook G4 manual which does shows how to open it up and change the HD, but I'm not sure how similar these two models are internally.
So I'd appreciate any clue as to the procedure for opening these babies up. Thanks in advance.

It's not an easy thing to do. Arm yourself with a tiny screwdriver and loads of patience:

How can you get a non-usb microphone to work?

So i've run into a few discussions on this topic, but never seen an answer to it. I have a non-usb microphone (A HyperX Cloud headset) that I want to use with my MacBook Pro. How can I do this? I'm assuming there is an adapter I can get for the microphone to work, right?

You will need a mic interface, you can get a pretty decent one for around $100, check this one out! http://www.amazon.com/Focusrite-Scarlett-Solo-Compact-Interface/dp/B00MTXU2DG/re f=sr_1_2?ie=UTF8&qid=1426555875&sr=8-2&k… or an adapter from http://www.amazon.com/IK-Multimedia-instrument-microphone-interface/dp/B00C68MZX E/ref=sr_1_1?ie=UTF8&qid=1426555978&sr=8… Sorry there is no other way around it.

Captivate 4 not detecting audio input from USB Microphone

I'm using a Logitech USB microphone in Captivate 4. When I try to calibrate it, Captivate 4 is not detecting any sound. It is set up properly. In the "audio settings" menu, this microphone is listed in the drop down list. I have selected it as the input device. However, when I try to "calibrate" this microphone, no audio is detectable. Captivate 4 is detecting the device, but not the audio input. I have double checked all the usual suspects--this microphone is selected as the default recording device. It does not use special software or drivers. It is designed to use the drivers in Vista. It works fine with other applications. I have made sure the input level is detectable. I've checked to make sure it is not muted. I have other microphones (non-USB cheapies) that work fine, but I can't get this specific USB microphone to work.
Suggestions?

USB speaker used to solve "No Audio Device is Installed" problem...USB microphone ok too?

After trying all of the solutions that have been offered for this extremely common problem of losing sound, I purchased USB powered speakers...and they work great.
Today I purchased a USB microphone and I can't seem to get that to work properly. Should this microphone work without the internal sound working properly?

Correct, microphone it totaly seperate and doesn't depend on sound.
Check your own devices or Sound panel window and under the Recording tab make sure your microphone is listed and make sure it's the default Recording device. You can rightclick it and set as default.

Kernel refuses my usb microphone after update

I guess the latest (or one of the latest) kernel update crashed the usb driver for my Blue Yeti USB microphone, it doesn't show up anymore in pulseaudio and isn't shown as a recognized usb device anymore:

Getting the USB microphone to appear in Live Meeting 2007

Optia AF camera under Vista, using Live Meeting 2007. The video works fine. But, neither Live Meeting nor Office Communicator lists the built-in USB microphones as a choice when configuring the audio. The only way I can get audio to work is by using the headphones and microphone connected to my sound card.
Strangely enough, the USB microphone works fine with Windows Sound Recorder if I set it as the default sound input device in the Windows sound control panel.
Anybody else have this problem and find a solution?

Performance tip: Keep the Desktop clutter-free (empty, if possible)
Mac OS X's Desktop is the de facto location for downloaded files, and for many users, in-progress works that will either be organized later or deleted altogether. The desktop can also be gluttonous, however, becoming a catch-all for files that linger indefinitely.
Unfortunately - aside from the effect of disarray it creates - keeping dozens or hundreds of files on the Desktop can significantly degrade performance. Not necessarily because the system is sluggish with regard to rendering the icons on the desktop and storing them in memory persistently (which may be true in some cases), but more likely because keeping an excessive number of items on the Desktop can cause the windowserver process to generate reams of logfiles, which obviously draws resources away from other system tasks. Each of your icons on your desktop is stored as a window in the window server, not as an alias. The more you have stored, the more strain it puts on the window server. Check your desktop for unnecessary icons and clear them out.
Keeping as few items as possible on the Desktop can prove a surprisingly effective performance boon. Even creating a single folder on your Desktop and placing all current and future clutter inside, then logging out and back in can provide an immediately noticeable speed boost, particularly for the Finder.
And it is why Apple invented 'Stacks' for Leopard.
Here is Apple's take on the subject:
