Digital Audio Beeps Once

I acquired this old unit from my school for free, I opened it up and found it was lacking some important RAM. Fueled by the desire to get a working computer up, I went out on the great depths of ebay and purchased this
http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=290468991709&ssPageName=STRK:M EWNX:IT
I also inserted a relatively fresh PRAM battery I purchased for my LG475 and that has been working fine in that machine. While the machine boots, the PSU seems to have either a very low power or no fan noise/movement, the side fan appears to be fine and a small red light on the motherboard lights up. As mentioned before, the one beep on start up happens and the power button light will flash every once in a while.
Now it is worth mentioning that the reason I believe this is a Digital Audio is due to the 3 ram slots and a little sticker that said 533mhz. Otherwise I am unsure of the specifications.
Any help on getting this computer running again would be lovely. Thank you in advance.

Hi litobro, and a warm welcome to the forums!
Otherwise I am unsure of the specifications.
Go yo this site & put in your Serisal# to find out more about it, or post the ML**** number here...
http://www.chipmunk.nl/klantenservice/applemodel.html
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
That's High Density. 64Mx4, Macs need 32x8 based memory devices...

So it has NO RAM installed it can use.

Install OS X on a Digital Audio G4 with a new HDD

I picked up a Digital Audio G4 from a university surplus sale and I thought I'd play around with it. Unfortunately it came with no Hard Drive, but I managed to scrounge one up. I've got a set of OS X 10.4 install CDs that I know work but I can't seem to get the computer to boot to CD. When I turn it on I get a few minutes of blank screen, followed by a blank grey screen for as long as I keep the computer on. No error beeps, no startup chime (though I'm not even sure the speaker works), just a blank grey screen. What am I doing wrong?

Do this:
Extended Hard Drive Preparation
1. Boot from your the Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

[Solved] Difficulty getting digital audio to play in all applications

This is probably a noobish question...
My motherboard supports digital audio out via S/PDIF cable (optical), as well as standard analog audio. I have a stereo receiver that I've plugged my optical cable into.
When I go to systemsettings > Multimedia > Phonon > Audio Playback, I put the "HDA Intel S/PDIF Digital" device on top and clicked Test. I could hear the test tone (playback source is PCM).
However, if I go to play an MP3 or whatever, I have to go into the settings for each application and tell it to use that particular device. Some applications (such as Firefox) do not have obvious settings for audio playback. Is there a way to solve the problem once and for all (tell the audio system "send everything through the digital device all the time")?
(I read the relevant section of the wiki, but it is focused on getting sound out of your digital device, not making it the default.)
Any other advice or gotchas about using digital audio would also be appreciated.
Thanks!

My .asoundrc looks the same as above. But just for fun, I also tried removing it and restarting alsa, with no change.
I'm testing output by going to systemsettings > Multimedia > Phonon and clicking the Test button with "HDA Intel (AD198x Digital)" selected. Nothing comes out through SPDIF, though it does play through analog (I have two separate pairs of headphones plugged in, one to the analog jack and one to a headphone amp plugged through the digital port) so I can tell which port the audio is coming from).
I've checked the hardware volume, and it appears to be in order. The amp is not reporting any audio signal on the optical port. I tried switching out the cable just to be paranoid, and still nothing. I believe this is a software problem.
Any ideas?

MBP- Digital Audio Out is always on

For some reason after (I believe) I updated to 10.4.9 the Digital Audio Out on my MBP is always on, thus making the internal speakers unusable. If I plug in headphones they work fine but after I unplug them it switches back to digital audio.
How do I fix this?
15" MBP 1.83ghz. Mac OS X (10.4.6) 1.5gb of Ram,

ok, since this prob comes up every week and often more than once a week, I wrote a detailed explanation and saved it so I could repost it next time it happened to someone. here it is:
the audio input/output connector on all mac notebooks is a dual function connection. it can switch between analog and digital optical. the way it does this is by an automatic sensor that detects what is plugged in. if it detects that an optical digital cable is connected, then it will switch to digital output and/or input mode as the case may be. this is why you see a red light - it's the optical digital audio stream. it seems that in many cases, people's connectors are becoming stuck, and the machine thinks there is a digital optical cable plugged in. it can happen if you've connected or disconnected headphones, or speakers, or possibly even if something is loose in that port and it just gets jammed with the sensor being tripped. people have suggested trying to gentle poke inside the port with a paperclip, to try and reset the sensor back to the setting that nothing is plugged in. for some people it has worked, for others, not. you can also try plugging in headphones and unplugging them a few times to see if it does the trick. if none of this works, then unfortunately the best bet is going to be taking the machine in for a service.

Digital Audio 533 Macosx install

Hi There,
I Bought a digital audio 533 and 2 120G Seagate harddisks. Installing macosx is no problem but when i reboot and going to update the mac the mac will hang en it forced me to reboot the mac. But then the **** begins i get every time aan kernel panic, its nog about the memory is al certifid apple ram so thats not the problem, when i boot from the dvd and run the disk utillity, it says that the keys on the disk are wrong and its inpossible tot fix it. So i runb the install again, first format the disk again, and instal macosx 10.4 but i get the same every time. Someone a idea? Maybe firmware?

Powermac G4 Digital audio Mac OS X (10.4)

Hi, profclimber!
For successful installation of OS X 10.2 or later, your Mac must have firmware updated to version 4.2.8. To check for this, boot to open firmware (depress and hold cmdoption+of at startup). When the command line screen appears, the firmware version will appear on the top line of the screen. To exit open firmware afterwards, simply power down with the power button, or enter "mac-boot" at the screen prompt, followed by pressing the Return key, which will restart the Mac. If the firmware is not up-to-date, go here for the installation instructions and download. Please note that if a firmware update is necessary, it must be installed using OS 9.1 (or a version of OS 9 later than OS 9.1 which has been installed on a drive in the Mac, versus being run directly from a disc or run over a network, etc).
In order to successfully install Tiger, you should be using a (black) retail install disc. (Gray) OEM discs shipped with a different model computer will very likely cause problems.
Before installing Tiger, use Disk Utility's Erase option to reformat the startup drive drive using the Mac OS Extended format. In that window, you'll see a button named "Security Options...". Click on it and check the box to overwrite zeros to the drive. Overwriting zeros will take some time, but will insure that your hard drive is clean of any old data artifacts which could possibly interfere with your install. It will also map out any bad sectors which may on the drive, preventing possible data corruption when you do the fresh install of Tiger.
I'd recommend disconnecting any third-party peripheral devices you may have attached when doing the install. When your installation is complete, you might launch Disk Utility and Run Repair Permissions on the startup volume before running Software Update. Do the same before any subsequent runs of Software Update and run it once more after your system software is completely updated.

Installing OS9 onto G4 Digital Audio

Hi,
I was directed here to get better help with this topic. As the title says, I want to install OS9 onto my Digital Audio G4 tower but having little success. I have ttried various discs (9.0, 9.1, 9.2) and none let me install the OS. The best I can get is the "Welcome to Mac OS 9.1" before the bomb screen shows saying there was an unimplemented trap problem. To get that far I have to boot off of a 9.0 disc to get the Floppy and ? error before I change to a 9.1/9.2 disc to start the installer. If I try to boot from the 9.1 or 9.2 discs directly, my Mac complains that there's no bootable medium. I have tried various images and even retail discs (including one that came with the original OSX package) to no avail.
Is there anyone that can help?
Thanks,
Naoki

Make sure your 1/2 AA 3.6V PRAM battery is under 4 years old. Make sure you are in fact using a Digital Audio:
http://support.apple.com/kb/HT3082
The Digital Audio never officially supported 10.5. If you used LeopardAssist to install 10.5 on it, double check with LeopardAssist's author that didn't affect your ability to use 9 with it, since 10.5 is not compatible with Classic, but is compatible with dual booting into Classic.
If the Mac has a third party processor upgrade, the firmware may have affected its ability to use 9.
Use this article to determine which versions of 9 CD can work with your Mac, once you have identified your Mac accurately with HT3082:
http://support.apple.com/kb/HT2191
Make sure your 9 retail copy says in black text the version of 9 that is newer than the minimum shown in the article:
9(.0), 9.0.2, 9.0.4, 9.1, 9.2.1 are all retail releases in the sequence of release.
The 9 CD has an orange 9 logo with a white background, and does not Upgrade, or Dropin on it, or any Mac model on it. Lastly, verify the startup manager can see the 9 CD after being inserted:
http://support.apple.com/kb/TA27043
And the curly arrow is clicked on it. If it doesn't see the CD, then it is not compatible.

Error Code EF01, Video and Digital Audio Dropping out

To whom it concerns,
A customer of mine is having problems with his Fios DVR. He will be watching TV through his Integra DTR 40.3 receiver, connected via HDMI cable and his picture and audio will just stop. This is always accompanied by a code that displays on the front panel of the DVR which reads EF01. The customer is usually able to restore picture and audio by performing a power cycle on both the AV receiver and the Fios Box.
There have been numerous occasions of this problem occurring. Sometimes it happens quite frequently, (once every 10 min) other times much more infrequently. Also the problems vary in their severety. Sometimes just the digital audio will drop out but the pitcure will remain. Other times the picture and audio will go out and they will damage the HDMi input that the Fios box is connected to, rendering it unusable. We have since repaired the Integra recevier twice. This last repair we haven't had an incident for 3 months, now we are back to losine Audio and Video.
The customer initially had the Fios DVR replaced, but as the incidents kept happening, we tried repairing and replacing the AV receiver. I keep coming back to that error code because I don't know what it means and nobody can explain to me if it has any significance or bearing on the problems we are having.
Does anybody know what the EF01 error code indicates on the Fios DVR? Has anyone had problems similar to the one I am describing, regarding HDMI video/audio loss?
Thanks,
Kelly White

Hey, Jared here.
The EF01 error code means that either the CableCard inside the box isn't getting any signal, or the CableCard isn't sending out any signal. A really efficiant way to see exactly what they problem is, is to take the box to a another location where Fios tv works fine.
There are two possible outcomes:
Either the box doesn't work, and is still displaying the EF01 error code. Than the issue is with that box, and I must be replaced.
The other possibility is that the box works fine. The error code goes away, and the box works perfect. If this is the case, we know it is the coax wires coming from ONT (Optical Network Terminal). And a Service Technician is required to come out and address the issue.

Overmodulated/distorted/garbled audio on G4 (Digital Audio)

Just got a used G4 (Digital Audio Model #M7688LL/A) from a somewhat nationally-known used Mac store for about $200. It has a 533 Mhz processor with 512MB of RAM. It had 10.3.9 pre-installed.
Everything works great. Even the startup chime. Perfect. But then after it has started up, the sound is horrible. From the alerts to playing music from iTunes, it sounds completely overmodulated or garbled.
I repaired permissions. I zapped the PRAM. Nothing changed.
I'm thinking it's a conflict between the OS and the old computer (it used to sell with OSX 10.0.3). The start-up chime is fine. Once the system loads up, yuck.
I plan to put in a call to the after-sales tech support. But I hope I don't need to ship it back or pay a bunch to have it replaced. I also hope I don't need to buy another copy of Tiger. Maybe Tiger would solve it (I found a support document here that said certain Powerbook G4 audio was garbled until installing Tiger. I don't know what to do and money is tight.
Does anyone have any suggestions?

It sounds like a hardware problem. If you call them, they will most likely tell you to ship it back. Alternatively, if you need some new speakers buy yourself USB speakers. That way the audio will be coming out through your USB, which I'm assuming works fine. However, 10.3.x doesn't support USB speakers, so you will have to get 10.4.

AES Digital Audio input to a Dual G5

I need to input SDI digital video and AES digital audio into a Dual G5 Mac. I see that BlackMagic will do the digital video part for in and out but it seems to only output digital audio. How can I get AES digital audio into the Mac. Any suggestions would be great.
Thanks

look for a used AJA I/O. firewire connect to your mac SD only supports embedded or AES.
The HD cards do both SD and HD the kona3 has a control panel that you tell it what you want, or FCP tells it what to do. once again embedded or AES. For analog you'll need an A>D D>A converter
Note that although the audio comes in embedded it is still a separate and editable element. also saves on wiring instead of AES 110ohm wire plus video it all comes down 1 wire. of course that means diddley if you're coming from an audio only device

OPTICAL DIGITAL AUDIO INPUT SPECIFICATIONS

I'm trying to find out what sample rates the digital optical input will accept as OK. I have a mic preamp that has a Spidif output that can select what sampling rate it sends out. Choices are the normal 44.1, 48, & 96K and 88.2 also. The first 3 rated are industry standards. Ideally I would like to set the sample rate output from the preamp to the rate "prefered" by the early 2009 Mac Pro 8 core if there is one, but I'm unable to find any mention of sample rates used by the Mac Pro input circuit.
The reason I'm asking, is that when I try to set system preferences of sound input, There is absolutely no level indication of an incoming signal when Digital input is selected as you can see in the screen grab below:
Any help would be appreciated.
Ken

Thanks for the tip. I had forgotten completely about that utility. Unforntunately, it didn't shed any light on the problem.
Even though I'm a longtime music & audio addict I made the mistake of overlooking the connections making good contact. Both the Mic Preamp and the DIgital audio converter had never been used before just like the new SPDIF cable w RCA connectors. I pushed the cable in until I felt resistance but didn't realize it wasn't fully seated.
After re reviewing my previous steps taken I noticed that the Digital audio converter was not showing a valid source signal. I inspected the connection once again and found I'd made a mistake that many newbies make, not unpluging & repluging connections when chasing down a missing signal.
Happy trails,
Ken

Airport Express (802.11n) - clipping digital audio output

I just replaced two older Airport Express with the new n-version. But for both new units, the digital audio output regularly pauses (skips) briefly every 10 seconds or so. It's unusable.
The music is being sent via iTunes to digital capable B&W remote speakers.
There is no problem with analog.

The problem persists with different cables, and after updating the Airport Express firmware to v7.3.1.
Once again, the problem does not occur with the older Airport Express - g model.

Tosliink Digital Audio MBP

Hey, I bought a toslink adapter, so I could play 5.1 surround through my MBP. When I hook up the adapter and the cable to my surround system, the computer does not recognize that I have it plugged into an external source. System Preferences reads that a digital audio is connected; however, it is as if there is no device plugged in. I checked to make sure that the receiver was on the correct setting for the input, and I cable when it was plugged in to the computer and not the receiver, and there was a red light, so the computer is giving out a signal. Any ideas would be appreciated. Thanks.

Found "Digital Audio" logic board, cpu & psu inside my Quicksilver ?

Recently got a quicksilver that "appeared" different to me . . .
Upon looking inside it's is a digital audio g4 swap (verified part #'s)
Logic board, 466mhz cpu and psu inside a Quicksilver case.
Any upgrades for this? does the dual 533 work in here?
Not sure what to do with this one, was hoping it was the sawtooth with the agp without adc (for testing flashed video cards without taping pins 3 & 11) . . .anyways

If you are just a TINY bit adventurous, get a QS CPU.
All you need to do is run a 12V line for fourth screw hole on CPU daughtercard.
Have a dig at XLR8yourmac.com, details used to be there...somewhere.
I once a QS 867 CPU and moved a resistor and made it a 933Mhz. I then ran over it with a rolling chair and knock a bunch of caps off.
Soldered them back on and sent it to a friend with a DA. He slapped it in and went on to do great things with that old DA. (like write the Mac Nvidia 6200 ROM)
The later QS 133Mhz bus CPUs had more cache, something like that. I know that the 867 was MUCH faster than a 733 I tried in it once.

Digital Audio not working on Satellite A505 S6012

My digital audio stopped working suddenly. I use HDMI to send the video out of my laptop to my projector. I had been successfully using, for over a year, a digital audio cable in the headphone (SP/DIF) jack to output the sound to my home receiver. The default audio set in the control panel is Realtek Digital Audio.
If I set the output to speakers and plug headphones in the jack, I get sound. If I set the output to Realtek Digital Audio and plug the digital audio cable in, I get no sound. I've tried new cables, changing the input to a different conection on my receiver, reinstalling the Realtek driver, and, as a last resort, completely recovering my laptop to the factory setting. Digital Audio still does not work.
Any suggestions? This is the main way we watch movies in my home.

hi, have you try out srs audio program it nice!
can u help me if u have make for yourself a recovery dvd of S505 S6012 because to mine i didnt do it and it gives me a lot of problems.
if you have please i would like to have it.
thanks....
