10.4.4 and PBG4 built-in audio

Following upgrade to Mac OS 10.4.4, no sound whatsoever is produced by my PB G4 15" aluminum built-in speakers, but plugged-in external speakers produce full normal audio. Any suggestions other than waiting for a bug-fix release?

Follow-up:
My PBG4 internal-speaker loss-of-audio after 10.4.4 upgrade turned out to be a misconnection associated with logic-board replacement. Not software-related. The Apple Store Annapolis fixed the problem while I waited, for free.

Built-in audio keeps disappearing - iBook G4 1.42 - what gives?

Last month I took my iBook G4 1.42 on the road and kept on getting problems with my built-in audio. I attributed this to movement, but I wasn't 100% sure. I took care of it every time by powering down, removing the battery, holding power for 10 seconds, replacing the battery, and rebooting. I don't normally need audio, but there were a few games that would stall and then exit if there was no audio output device seen in the configuration.
It's been at home for a few weeks (my wife is the primary user) and it behaved pretty well until the built-in audio wasn't seen in the configuration again. I tried the old power-down trick without the battery again, but audio wouldn't come up. The whirling icon showed up when I tried to access most of the stuff on the top bar, but eventually settled down with no audio volume icon. I then tried holding down command-option-P-R while booting to reset the PRAM. Then it booted with the Mac chine and the built-in audio was fine.
Any idea what's going on. Yesterday was the first time built-in audio disappeared when I wasn't on the road, and the first time pulling the battery and pressing power didn't solve the problem.

Thanks for the suggestion. I think I came across the suggestion when I looked for how to reset the PRAM, but I didn't think I needed it at the time. I'll try it if the audio goes out again.

I want to be able to use airplay to stream audio to another iOS device, and then use that audio stream to be used when recording video instead of the built in microphone / microphone input. Is this possible?

A third-party app probably cannot obtain a stream from another app. To the best of my knowledge, such a capability is not provided in the software development kit, apps being "sandboxed" from each other and so allowed to communicate only in very specific and limited ways.
I'm not completely sure what you mean by "limitations on video capture". An iPhone, to the best of my knowledge, can natively record video only through it's built-in camera, and audio while doing video recording only through the built-in microphone or mic/headphone jack. There might be a video recording app that would allow audio input from an external device connected to the dock connector, but I'm not sure.

HT2375 Using logic 9: play back of all project files now has problems: Track volumes are way off - if panning is set to center then you cant hear that track? Even if pan is adjusted tracks are low and or distorted I have looked at core/built in audio

Been having project play back problems for about a month. Sometimes when I open a project the volume of certain tracks is low and or distorted. Oddly if a midi track is panned to the center (0) its volume is too low and if I pan right or left the track becomes louder. Sometimes this doesn't help and if it is an audio track things become distorted.
Although things have been working good for about a year now I think it has something to do with the fact that I have to take the laptop to work and use headphones/built in audio for play back and then take it home and use different audio interface but I can't be sure. The settings in preferences/audio/devises seem to be correct.
I have not added any plug-ins recently. I have not downloaded any new programs recently other than a NI tutorial video (shouldn't have any affect) but I am trying to use a new midi controller but again that shouldn't have any affect on play back of existing track?
Any suggestions?

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

Built-in audio inputs and output don't respond to anything.

Hi there,
Maybe somebody can help me, I have a macbook pro os x 10.8, and i'm having a bit of problem.
I connected a cable to the line input, and before i had a chance to balance the high volume the whole software in the system preference froze, and now the built-in audio inputs and output don't respond to anything, also in the audio MIDI setup menu. The volume button moves extremely slow, and there is no sound at all. Anybody has any idea?
Thanks in advance

Apple store genius bar seems like you best bet.
Ciao.

Utility to switch between Bluetooth headset and built-in audio input/output

I'm looking for a utility that will switch the Sound preference settings between my Mac's built-in audio input/output device and my Bluetooth headset for use with applications such as Skype.
The way I envision it working is that I would click an icon at the top of the screen and it would toggle the Sound preferences settings from
Output = Line Out (or Digital Out)
Input = Line In (or Digital In)
to
Output = (my Bluetooth headset)
Input = (my Bluetooth headset)
or vice-versa.
That's it. It doesn't need to automatically detect my headset as I might be using the headset on another device. Just a button that would toggle between the built-in and Bluetooth device settings.
Has anyone seen anything like this?

Thanks, it works great.
It would be even better if one could define device groups. e.g. Headset, built-in devices, etc. I'll drop a note to the developer.

When recording a video using quicktime and my built in camera (isight) how come the program wont let me use my audio interface rather than the built in mike?

The basic answer is that Apple has not programmed the capture routine with this capability. As such, you can always send QT feedback requesting this feature be added as a future enhancement.

Voice over tool & built-in audio

When I open FCE, I routinely get a message "unable to locate built-in audio." I ignore it and continue, so far as I know without any bad consequences for my projects. Sound input and output seems fine, except when I try to use the voiceover tool.
My mic is hooked up through a Tascam US-122 usb connection. Indicator lights on the usb interface show that the mic is working, and the sound preferences panel also shows the sound from the mic coming into the computer at normal levels (the input levels indicator lights up when I speak into the mic)
My voiceover tool settings are Tascam US-122 for source and for input. My output is set for headphones. Adding to the mystery is that on rare occasions, after trying many changes in settings and closing/reopening the project, the voiceover tool will suddenly work properly (I haven't been able to isolate a cause). Today, however, nothing I do seems to help. I recently upgraded to osx 10.4.10, but the problem existed long before that. Any suggestions?

Hi(Bonjour)!
There is an issue with some USB based sound devices and FCE HD.
You can use Soundflower pref panel to allows virtual "rewiring" of your audio from input source to output destination. That may resolve your problem.
Search this forum with "soundstick, USB, soundflower" keywords.

Macbook Air Mid 2013 No Built-In Audio

Hey everyone,
I have an issue with my friends Macbook Air (Mid 2013 Model). After listening to some music through his speakers, he unplugged his Aux cable and then plugged them back in to find that he didnt have built in output or input anymore. I have tried all of the following to fix it:
Reinstall OS X 10.8
Run all of the Automation tools found in the application Onyx
Reinstall certain .kext files (AppleHDA and AudioAUUC)
Repair permissions
Re-seat the speakers in the device itself
Reset coreaudio
Resetting SMC, PRAM, and NVRAM
Clear and re-build kernal cache
Cleaned the headphone jack
Plugged in an audio interface
Reloaded from Time Machine Backup
etc...
I've literally tried almost everything in the book. The only other thing i can think of is installing a copy of Mavericks when it comes out (In October i believe). There is no boot up chime, and after running the OS in verbose mode, i can see that AudioAUUC.kext is not being loaded. Built in audio does not appear is system profiler. What can i do to fix this problem? Could it really be a hardware issue? If so, what can i do to fix it?

Test after each step.
1. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
    Option click the speaker icon, if present and select Internal Speakers.
2. Plug in the head phone and reset SMC.

How do I use the built-in audio input with AU Lab?

I just tried AU Lab for the first time, and I can't select an audio input.
The "Create New Document" window lets me choose "Built-in Output", but the pulldown for Input Source is greyed out. The area under the "Input" button says, "Audio Input Not Supported". How can it not support the built-in audio input? I even tried using SoundFlower to route the signal from the Line In (a small app) to the Input of AU Lab. AU Lab's display then shows two channels from Soundflower, but they are still greyed out.
All I want to do is get a signal from the built-in audio input routed to AU Lab so I can use AU effects to process the audio signal in real time. How do I do this?

They comes configured with your software. If you want to use, for example, Skype, you need to run the configuration wizard section.
Best regards.

Built in audio failure

I have tried to find this topic in the boards without luck. My MBP (2 years old now, with OSX 10.4.11) has lost all internal audio - no speakers, no headphones, no internal microphone . I was unplugging my guitar cable from the input jack (actually the cable from the amp) using garage band, and that seemed to trigger the audio to die. System Utility reports "no built in audio" hardware, and System Preferences reports no audio input or output devices. However, I can still use airtunes. Also, no chime at start up - no sounds at all. What happened? Anything else I can try?

Any chance recommending an appropriate microphone?
You can use your current microphone via the iMic
<http://store.apple.com/uk/product/TX532ZM/A?fnode=MTY1NDA0MA&mco=MTI5ODU0NzQ&s= topSellers>
Which is better USB or mic with amp?
USB is usually more convenient since a pre-amp needs power. The sound quality depends entirely on the microphone. There are some high-qualty USB microphones, such as:
<http://store.apple.com/uk/product/TF238LL/A?fnode=MTY1NDA0MA&mco=MTY4MzcwNzA&s= topSellers>
There are also USB pre-amps for high-quality XLR microphones

There are also low cost USB microphones and headsets.

Built-In Audio Panning L&R malfunctions, system prefs.

I have noticed on my own Mac, as well as my peers' computers which include iBooks, PowerMacs, iMacs, and even a new MacBook pro, that the audio coming from the Built-in audio card will randomly be panned completely to the right, or the left.
A quick troubleshoot will lead you to find that in the system preferences the panning slider is set to the right or left, an undesirable setting.
All of the computers I mentioned are running the latest updated versions of Tiger, 10.4.6, and with the exception of my self running Pro Tools, none of the other computers mentioned are running any third party audio interfaces/cards or software that uses audio other than the applications included with Tiger: iTunes, iChat, Quicktime, Safari, etc.
Unfortunately there is no Lock in the audio system preferences, which could potentially be a quick fix to the problem because if an application like iChat had a bug which caused audio panning, the lock in system prefs. would prevent that..
I am quite boggled.
question:
What might be causing this, and is there a solution?

Thanks for the response guys. It seems we're in the same boat.
The problem is intermittent on my machine . It has occurred three times since I bought it. The fist time it lasted for a day and a half. I rang Apple support and went through a number of steps until the P-RAM suggestion which seemed to fix it. A few days later it disappeared again and resetting the P-RAM had no effect. My wife continued to use the computer (without sound) and some hours later it came back after a restart (she only restarted it because she is in the habit of shutting down instead of using sleep). The problem occurred again. That time I restarted the machine a number of times, with and without the external speakers plugged in, with them turned on and off etc. This had no effect. I gave up. Some time later my wife went to use the computer and it came back. I now believe that the P-RAM solution that seemed to fix the problem the first time was just a coincidence.
I rang Apple support again and they gave me the following steps (A,B & C of which I went through the first time the problem occurred):
A: Log in through another account and see if it had the same problem.
- The built-in audio was still missing.
B: Run the disk utility on the hard drive (after booting from installation DVD).
- There were nil problems on the HD, but it did not fix the problem.
C: Reset the P-RAM.
- This worked the first time though it has not worked on subsequent re-occurrences of the problem.
D: Do an Archive Reinstall.
- I did this today; though the built-in audio was working, I just wanted to complete the suggestions the Apple support person gave me. The problem has not reoccurred yet, but it has only been a few hours. I will be using the computer as much as possible tonight to see if the problem reoccurs.
If the problem reoccurs I'll be taking the machine in for warranty repairs, or better still replacement.

Built in Audio not working in MacBook Pro after update to 10.7.3

The Built In Audio is not working in My MacBook Pro (Early 2011) after update to 10.7.3; I tried resetting the PRAM and SMC but it didn't helped me out. I can get audio only if i reboot my mac from Safe Mode or reboot after Repairing Disk Permissions in disk utility using the Recovery Partition;. If i make a normal restart or just startup then the built in audio disappers (audio is displayed gray in the menu bar) . Everything was working well with the 10.7.2
- Audio Works well with the Boot Camp Partition. and There is a sound during boot up.

I dont have any backups and i dont have time capsule or an external hard drive ready to be used for backup.
My macbook is my the only one computer. The problem is that the animation is lagging when i change the window to dashboard or safari or mail or another window. Inspite of this my macbook works well.
But 5 minutes ago, I noticed that if i run autocad on my mac- the lags go away!!!!

What is "Analog Output - Built-in Audio"?

Hi,
In Gnome System Settings -> Sound there are three pulse sinks: HDMI (Built-in Audio), Speakers (Built-in Audio), and Analog Audio (Built-in Audio).
When I plug-in headphones into the laptop, "Speakers" change to "Headphones". The behavior is what I want, but I was just confused as to what "Analog Audio" does? As far as I can tell it doesn't do anything. In Ubuntu 13.10 I didn't have the Analog Audio sink.

Built-In Audio Devices disappeared

Greetings everyone,
I got a big audio problem.
The Built-In Audio Out and Inputs of my iMac (2011) disappeared in system preferences and i noticed the coreaudio process has high CPU usage all the time. Even force quitting isnt helping, as it restarts immediatly.
Furthermore my computer is hanging on shutdown:
If it's entering sleep mode, the display goes black but fans and HDD are still spinning, but I cannot do anything else and I have to do a hard reset. The same happens when i'm restarting or shutting down. It just won't shut off completely (I guess because of that hanging process)
I booted another OS X installation and everything worked fine, so there's clearly an error somewhere in my current OS X installation. But restoring from a Time Machine backup didnt help.
Are there any files/caches I have to move to trash or anything else to fix this problem without having to reinstall OS X once again?
Thanks.
