Mac OS 9.1 for PM G4 digital audio

I have a PowerMac G4 digital audio and want to install Mac OS 9.1 on it. That particular machine requires a version of 9.1 with ROM 6.7.1, different than the standard 9.1 installation disk.
Anyone have a lead as to where I could obtain the correct disk (or, download that particular ROM)?

Did you ever find a copy of this OS?
In a similar boat here, the only way I can get all of the software/drivers that I need to work is to run OS 9.1 - so I am trying to replace my 2x1Ghz G4 running 9.2.2 with a 733MHz G4 DA... bought one off of eBay because the guy said he would include the 9.1 disc (even though it was running 10.4), well, after I paid he wrote and said he couldnt find the disk. I called Apple and they said that I could get a replacement disc from them (for $12?) so I told the guy I would take it anyhow (and he said he found the disc) ... well, got the computer and the included disc was for an iMac, no big deal, called Apple - and this time the person says that they no longer carry that OS - and there's nothing he can do (this was like 5 days later so I can see how things would change). So now I have a whole lot of crap that I can't use - and really no where to turn ... I have been looking for this disc for months now.

Processor and Graphics query for G4 PowerMac 'Digital Audio'

Hey all, two questions here...
Question 1
Ive got ANOTHER new processor and graphics card for my Digital Audio G4. The processor i had in it before was a Sonnet Encore ST/G4 1GHz, ive replaced this with the same make of processor but at 1.4GHz. The processor works fine and the machine runs fine, but it isn't listed properly in the system profilers...
In OS9 it's speed is described as "about 656Mhz" and in OSX its described as 0MHz!
Im not too worried since everything seems to be working fine, but i want to be sure that its not going to suddenly blow up on me, and if anyone else has had things like this happen with these processors or configurations. Ive still got the 1GHz should anything go wrong, but newer, more powerful stuff is always good!
Question 2
The new graphics card i put in is a ATI Radeon 9600 Pro PC & Mac Edition. Ive read a few things on the internet about it sometimes not working with DA Power Macs but thought id chance it anyway, i can always sell it on if it didn't work...
Well the card works in both OS9 and OSX and displays everything fine, its recognised by both systems and everything. The only problem is i can't change the display settings, on both systems the only display option ive got is x736 (or whatever it is thats closest to it), there are no other options available, i can't choose anything else in the Recommended menu, not can i change from Thousands to Millions of colours.
Of course its generally agreed that these cards work better on G5s than G4s, despite it saying on the box that it supports G4s. Ive also downloaded the ATI Displays Control Panel to see if i can control it that way, but to no avail. Does anyone have any info or words of advice on this?
Cheers all!

Good to hear, thanks!
Do follow the advice to add as much cooling as you can, & use the best Ceramique Thermal Paste you can find.
Did you clear all the Caches yet?
At this point I think you should get Applejack...
http://www.macupdate.com/info.php/id/15667/applejack
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.
Just sits there occupying very little space & never interfering, unless you need to invoke it in Single User Mode.
Look for the 10.3 version of AppleJack 1.4.3.1 (326 KB) (For Mac Jaguar and Panther), here...

RAM for a G4 (Digital Audio) 467 MHz?

Hi,
The mac I use at work is (I think!) a G4 (Digital Audio) 467MHz model running OSX 10.3.9 Panther. My employer has said he will consider ordering more RAM for the computer and has asked me to do the legwork. Ideally I want to max out the RAM on this computer because it's unlikely my employer will be replacing it any time soon.
From reading this forum, I gather that Macs can be picky about RAM - I'd like your recommendations about what/how much to buy. Currently two slots have RAM of different sizes - am I correct that the computer will work more efficiently if all the slots have the same size RAM?
Here are the specs for the computer:

Your G4 DA uses 168-pin PC-133 (unregistered, non-ECC, non-parity) SDRAM. A 16-chip (8 chips on each side), 512 MB DIMM is the largest that's supported in each memory slot. As long as the SDRAM meets the criteria, it doesn't need to be purchased from a Mac memory dealer, although you may have fewer compatibility problems (since some memory merchants aren't really familiar with Mac memory requirements). Unlike some PCs, Mac OS X doesn't run well with inexpensive/marginal quality memory, so your choice shouldn't be based on price alone. You can check out this dealer's prices, and compare prices at Ramseeker.com.
As far as mixing memory having different density chips, you may find a performance boost by using similar-density memory. A 512 MB DIMM with 16 chips and a 256 MB DIMM with 8 chips both have 256-Megabit chips. A 16-chip 256 MB DIMM and an 8-chip 128 MB DIMM have 128-Megabit chips. A 16-chip 128 MB DIMM has 64 Megabit chips. If your 128 MB DIMM is low-density memory, having more than 8 chips (either on one side, or 4 on each side), I'd remove it and replace it with something larger.

Solaris 10 x86 5/08 audio driver for SoundMax Integrated Digital Audio

Hello out there, I recently installed Solaris 10 x86 5/08 on my IBM ThinkPad T60 (2007-63U) and I'm really impressed how well it is working.
The only thing I've found not working so far is the audio.
I've installed the Solaris Audio Drivers 1.0 from:
http://www.sun.com/download/index.jsp?cat=Hardware%20Drivers&tab=3&subcat=Audio%20Devices
...but it still is not recognizing the audio device.
Everything else is working great (thank you Sun and the OpenSolaris Community!!!!!!!), so getting the audio working would be even better.
Any pointers anyone has on what to look for on the system (e.g. in /var/adm/messages) or how to configure the audio to support the SoundMax Integrated Digital Audio would be greatly appreciated.

...well, I've tried building oss-v4.0-build1016-src-cddl but I haven't been able to get it to work.
In preparation for the build, I did install Sun Studio 12 (from http://developers.sun.com/sunstudio/index.jsp ), patched it, and installed gawk-3.1.6 ( from http://www.sunfreeware.com/indexintel10.html ) and ran configure/make install as instructed which successfully completed.
The following is what I get when executing ossdetect:
================================================================================
rem_drv osscore
rem_drv hdaudio
rem_drv ossusb
rem_drv sadasupport
Driver (osscore) not installed.
unloaded osscommon
add_drv -m '* 0666 root sys' osscore

devfsadm: driver failed to attach: ossusb
Warning: Driver (ossusb) successfully added to system but failed to attach
add_drv -m '* 0666 root sys' sadasupport
/dev/mixer: No such file or directory
================================================================================
To note, the Solaris 10 x86 5/08 installation I am running on is the full distribution +OEM.
I also cannot find the "soundon" or "soundoff" scripts referenced in the OSS build instructions.
Any pointers would be appreciated.

Play Digital Audio In

Is it possible to play the "Digital Audio In" over the "Digital Audio Out"? I am hoping to be able to play the digital audio out of my Power Mac G5 over my new Mac Pro tower. I have the digital audio out of my G5 plugged into digital audio in on the Mac Pro tower. I can see the meters on the digital audio in moving, but no sound is playing through the speakers. What am I missing?

I've used my iMac's digital out(c. Tiger) to connect with my Mac Pro's digital in port(c. Vista and OS 10) using a toslink cable for sound effects etc.
I've had to remind myself to specify in the Mac Pro through OS X's system preferences what sound output I am listening to. For example: whether it's headphones, line out or digital out.
Beyond that, I would guess it depends on your software and how it outputs your sound. The meters in "digital in" moving is always a good sign. It remains for you to examine the resultant sound file and see if the sound "got through".
I know this sounds vague but I hope it helps.

Digital audio ouput - why no volume control??

This is a problem that has been around for a while (ie. pre-Leopard).
Why is there *no global volume control* when using digital audio output? This includes the inability to mute the output as well as adjust the volume with either the keyboard or the apple remote.
It is *particularly annoying* with Leopard's Front Row as music is not being played via iTunes anymore so I can't use the iTunes volume control...
Please fix this Apple, it can't be that hard. There is no logical reason for disabling volume control for digital outpu!
Thanks,
Paul Martin

nitramluap wrote:
It IS possible, actually and its omission makes no sense.
Yes, it is possible but it isn't desirable. Here's why:
For any linear digital audio encoding process, the bit depth determines the resolution of the volume levels the format can reproduce. For example, for 16 bit audio there are 65536 possible volume levels between dead silent & the absolute maximum possible level (digital clipping). For 24 bit audio there are about 16.7 million levels.
So let's say that you want to turn down the volume at the digital output. The only way to do this is by throwing away all of those levels louder than the desired volume by scaling the output to what is effectively a lower bit depth. One half as loud means the most significant bit ("MSB") will never be a one; half that loud & the next MSB won't be used, & so on.
At first, this doesn't seem so bad but the problem is the human ear doesn't interpret "one half as loud" as you might think: hearing is logarithmic (which is why we usually use the logarithmic unit "dB" to measure it), so a sound that is 1/2 the intensity of maximum is only slightly quieter to the ear. Depending on the maximum level the digital input device can produce, it could easily be necessary to scale the digital output to one ten thousandth or less of the maximum output just to achieve a comfortable level, & to scale it much smaller still for background music levels.
So, for an effective volume control with a usable range from "very quiet" to "full tilt" you would really be going from "miserably inadequate resolution" to "high quality resolution."
If you want to hear just how miserable sounding the quiet settings would be, & you have any sound editing software that can change digital volume levels of samples, try this:
Select a short sample & reduce it by 40 dB. Save it & then renormalize that saved sample to full scale. Listen to the result & compare it to the original. Not too pleasant, is it?

How to add SPDIF/ digital audio to HP Pavilion dv4??

Is this possible with having to get the HP Dock?? I don't need any of the connections on the HP Dock except for the SPDIF/ digital audio one. Is there another type of adapter I can purchase? Thanks.

I understand you want to know how to use your dolby audio.
Have you tried installing the newest audio driver found here? The driver includes the dolby software and the IDT audio control panel should have separate adjustments available for Dolby. With the driver installed, try opening the IDT audio control panel and verify if that functionality is present.

USB Audio Driver need in Digital Audio playback of iPOD in IUI Mode

In iPOD User Interface Mode for playing the Digital Audio from iPOD using USB, does the complete USB Audio Driver needs to be created or is it enough to set the sampling frequency of the USB ISO endpoint.

Hi! Did you ever find a solution for this problem? Bought an SB Li've! External just yesterday and on a clean install (Windows XP SP2) I'm having the exact same problem.
Edit: By switching the USB port from 2.0 (Hi-Speed) to "normal" (USB .x) in the bios I got rid of this problem! Hope this might be of some help to anyone!Message Edited by yuzz on -04-200706:37 PM

Optical digital audio output for mac book?

Hello, I am wondering if MacBook pro Retina version has the Optical digital audio output or thunderbolt adapter? so i can use optical cable to do output for my music.

Hi alece,
Just to clarify something;
When using an optical cable there are several standards of audio that can pass through the cable:
S/PDIF - a stereo signal - http://en.wikipedia.org/wiki/Spdif
AC3 or Dolby Digital - up to 5.1 surround - http://en.wikipedia.org/wiki/Ac3
Dolby Digital Plus - up to 7.1 surround - http://en.wikipedia.org/wiki/DolbyDigitalPlus
ADAT Optical - up to 8 channels of audio - http://en.wikipedia.org/wiki/ADAT_Lightpipe
MADI - up to 64 channels of audio - http://en.wikipedia.org/wiki/MADI
I´m sure other people can add more to the list if they want to, my point is that these signals can pass through the exact same kind of optical cable.
The important bit to know is what does your equipment and software support... in theory your question is quite logical, a software can play 5.1 surround to a optical output like Apple DVD Player does with the built-in sound card of a modern mac. However, Logic does not support live encoding of AC3. That is why you have to output the surround mix in Logic to a sound card with at least 6 channels (5+1 as in 5.1) connected to your speaker system. Typically this would be 5 active studio monitors plus a sub. If you were thinking to use an existing stereo I would not recommend it since most consumer speakers have no limiters to protect them from damage (but may be possible depending on your amplifiers inputs)
I hope this answered your question

Upgrading from 10.4.11 to 10.5.8 on my G4 Power Mac Digital audio-is it worth it and how do i find the 10.5.8

Hey Gang.   How's it been going? I still have the same G4 Digital Audio which came used but with a clean OS, which I managed to up
grade to reach the 10.4.11. Its works great and I love it. I can only imagine using a real Mac Pro 2012. The software is legacy and It will not support the QuarkExpress9 for example. So what if I found and upgraded to the 10.5.8 or the max OS my G4 can handle? Is it worth it?
Thanks

Hi,
Depends what part of 10.5 you think you need, but 10.5 does not support Classic Apps, requires 3 times the resources & space, is expensive, & slower than Tiger/10.4 even on a G5 Quad with 10 GB of RAM.
I have run 10.5.8 on a DA/450 MHz/1GB, & it is possible.
Leopard requirements/10.5.x...
    * Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
minimum system requirements
    * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
    * DVD drive for installation
    * 9GB of available disk space (I say 30GB at least)
Classic/OS9 Apps no longer supported.
Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...
http://www.ebay.com/sch/i.html?_nkw=mac+os+x+leopard+retail+10.5
There are workarounds if the 867MHz CPU is the only hangup...

HT4806 Mac mini digital audio out through the headphone jack

I'm misled by this sentence for audio out port from the support page: "For digital audio, you can use Apple iPhone headset with microphone".
http://support.apple.com/kb/ht5539
It is there for all mac minis starting from 2010 model.
Does it mean electrical digital signal? Any chance to get S/PDIF coaxial signal?

If an optical signal is OK, you just need one of these:
http://www.amazon.com/dp/B00016W6Y6
To convert the optical signal to a co-ax one will need a more complex/expensive convertor.

Using built in optical digital audio output for 5.1

So, lets say i want to mix something in 5.1 using logic or soundtrack pro, can i use the optical digital audio output of my macbook to send the signal to a home theather or something to mix it?, or i need a special hardware card for this?

Digital Audio Broken on a Mac Mini (early 2006)?

I've got an early 2006 Mac Mini 1.83GHz which I'm trying to use as an HTPC. When plugging in an TOSlink to miniplug cable to the audio port I get the "flipover" to Digital Out in sound preferences but no sound from my Pioneer AV receiver. I've made all the correct adjustments in the receiver preferences and tested them with a iMac and sound plays through just fine.
Headphone and Internal speaker work fine on the Mini and the cable is fine as noted above with the iMac test. Is it possible that the optical digital audio portion of this jack is bad?
Apple Support doesn't seem to think it is hardware related. I've re-installed OSX and checked permissions. I don't have the restore disk to be able to do a Apple Hardware Test and the Leopard disk does not contain it.
Any ideas as I've run out aside from taking in to an Apple Store for evaluation?

Took to Apple Store and they fixed the unit with a new digital audio card. $49. I'm happy.

Mac mini firewire vs Mac pro firewire, trouble with medium format digital back

Hi
I'm trying to use a Mac Mini to run a medium format digital back, I have problems with the connection between the digital back and Mac mini dropping out randomly meaning I have to unplug the firewire and restart the back, sometimes restart the software.
Manufacturer says it is due to Mac mini firewire not supplying enough stable power to the back and to use a powered firewire repeater.
I've tried that it hasn't really made much of a difference.
Manufactuer now says the Mac Mini's are just not up to the job they are significantly diferent to the Mac pro range.
Is this correct?
So I can't use a small form factor mac mini to do a single task - tether to a camera and run camera software. Doesn't really seem that big an ask?
thanks in advance.
Nigel.

you may think it's a single task, but that's on top of the underlying OS processes. also, i'm assuming that your mini is only running a single hard drive, which means your software is competing against the OS for access to the write heads on your drive. have you confirmed that your system memory isn't generating too many page outs? if you're in activity monitor and you see that count increasing, you need more RAM.
you could also try to install a second hard drive in your mini, and designate that drive as your write target for the camera software.
is this for video, or stills?
