Power Mac G5 :: Digital Audio In To Line Out Speakers All Noise?
Nov 5, 2007
I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.
I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.
Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.

I'm a recent PC to iMac convert and have hooked up my iMac to my TV receiver (DVI to HDMI connector and a Toslink cable to the audio). The issue is as soon as I plug in the audio connector the iMac speakers stop working. I'd like to leave the connector plugged in and still be able to use the iMac speakers. Of course when I play a movie on the TV I'd just mute the iMac speakers.
I have a G5 twin processor which I bought just before the Intel chip model. It has all sorts of hum and noise in the audio line out when connected to my larger home music system. I have Applecare and the Apple Store tells me that they need to replace the motherboard. I'm awaiting that part to come in now. However, it sounds to me more like old fashioned transformer hum and I'm wondering if anyone else has had this vexing problem -- and if so, how it was finally resolved? I'm too old to keep hauling the heavy unit around much more.
I'm connecting my mbp to my new lcd sony bravia via dvi to hdmi lead and then connecting the sound via headphone jack to tv's 2 x phono, however i'm getting lots of audio noise bleeding through tv speakers underneath the main audio feed, i'm certain that its not a dodgy lead as iv'e tried 3 of them, however if i unplug the dvi lead the noise goes away, is it possible that the hdmi input is conflicting with the phono connection somehow.
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?
Step by step instructions for using an ATX 24-pin power supply in a Gigabit Ethernet/Digital Audio Powermac G4 (one way to do it anyway): First, know that to boot the G4s up, you MUST have at least +12V of power going to the G4's pin #22 spot (white wire) even with the computer turned off. This is called standby power (I didn't know what it meant until a few days ago). ATX power supplies generally only have a +5V SB power source which is not enough. You must use some method of getting the +12V to +28V standby power to the G4's pin #22. I will outline the method I used but there are others (ideally get a ATX power supply with +12V standby, but they are not so easy to find). I am typing this on my G4/533 with an Antec SP-500 power supply. Why do this? With an ATI Radeon 9800 256mb graphics card, three hard drives, a DVD drive, a SCSI card, a USB 2.0 card, a USB 2.0 hub with four devices attached, and a newly aquired G4/1.4 Ghz card (which meant two additional fans for cooling control), I figured the original power supply was overextended. So, here's how it can be done:
1. Make sure the ATX power supply you want to use fits your case and has the power cord hookup in the correct position (lower left corner). 2. Make sure the ATX power supply has a long enough motherboard harness, or else you will need to buy an extension (which you may want to do anyway to avoid mutilating the original power supply's wiring harness). 3. About three inches from the motherboard harness connector (same with all future cuts), cut the ATX wire #8 (gray). Tape the end of the gray wire going to the power supply. You don't use it for anything. 4. Cut wire #12 (orange). 5. Remove 1/2 inch of wire insulation from the stub of gray wire coming from pin 8 in the harness connector and from the long orange wire (that used to go to pin 12) that goes to the power supply and solder them together. Cover with heat shrink tubing (which you must put on before you solder) or electrical tape......
15 inch MacBook Pro. Internal speakers will not play. Output to headphone plug did work. Now I cannot insert headphones into socket, it seems to be too shallow. There is no red glow as mentioned in other posts. I had the red glow issue on an older MacBook and resolved it by inserting toothpick into socket and triggered switch. I have used command, option, r and p reset.
Why can't I hear my music keyboard when it is connected thru the Analog Audio line-in port? Looking at the System Pref. - Sound menu - in-put - Line in Built-in Audio, I can see activity on the input levels when I press the Kawai piano keyboard but no sound is heard. All other sound systems- I-tunes etc are operating properly.
I'm coming from a good 7-8 years with an old G4, so forgive the ignorance. On that one, I added a PCI audio card to connect with some Altec Lansing speakers with Sub-woofer & simulated Surround sound. It sounded great. hat's your suggestion? Get a similar card for the G5?Or get some new speakers that will sound as good?I don't know anything about digital audio out. Does that connect to speakers, or only tuners?
I thought you should be able to.Play iTunes audio out through USB to a receiver equipt with USB mode as I can with my iPad Air, but I can,t find in preferences on my 2013 iMac any out put and I get no signal to the receiver/amp. Is it possible? What am I doing wrong?
Info: iMac (27-inch, Late 2012), OS X Mavericks (10.9.4)
Situation: no sound out from speakers in admin and user account and newly created account. Headphones work, startup chimes work on speakers.
Go to Sound in Preferences and only shows Digital Out for output. Should show Internal Speakers. Ran Diskwarrior and Applejack and zapped pram. Took mac apart and confirmed speakers wired correctly which is verified by the start up chimes being audible on the internal speakers. tested all accounts and created new account all with the same results. Did search of Google and MacRumor. Found one unaswered post indicating same problem. Had same problem with another macbook pro, ran same steps, take apart, confirm wiring setup, Diskwarriored, applejacked and zapped pram and it fixed the problem. I'm not sure what else to try. Did check Audio Midi Setup util and it also did not see the internal speakers.
Seems like it should be a straight forward deal, but it's not obvious how to make this happen. I can tell the audio is coming in, as the input levels are reflected under System Pref's. But I can't hear the audio on the line-out speakers and there doesn't seem to be an option to explicitly route the audio.
Trying to figure out if something is up with mine and a buddies machine specifically or they are all buggered....
Please post if you have an audio pop or click type sound that is intermittent (every few minutes or couple hours) on your i5 or i7 machine while playing audio through external speakers.
If you have it, please describe your situation as it occurs so we can perhaps isolate it:
I.e. Plugged in / on battery, programs running, usb plugged in, etc.
Mine happens whether on battery or not, iTunes, games, movies, Locked in video card...
I have audio that is being sent to my MBP through an audio in line that I would like to monitor for audio quality. The only way I know how to listen in real time to the audio is by way of Audio Recorder, but it seems a little unnecessary to have a recording application open simply to listen to my media that is being sent in. Is there a feature already part of OS X that allows me to turn this on? I looked in system prefs, but couldn't find anything to enable this. I will resort to audio recorder if I have to, but would be very happy if this was already a feature.
My friend is looking into buying the new 27" iMac Core i7 to replace his PC desktop. The only thing holding him back is that he has an analog surround sound system he uses for his speakers. I am having a hard time myself finding a converter that can make his speakers work in the iMac's optical digital output port. Any products out there that will do that?
My MacBook Pro seems stuck on digital output thus no sound from speakers. Headphones recognized and work but internal speakers don't revert to default or even show up as a sound option in System Preferences. Any way to get internal speakers back? Restarting computer did not do it.
I recently upgraded my macbook pro 2.16 to a western digital scorpio (WD3200BEVT). The first day I did not notice the noise at all.. Now it seems to have a clicking noise every 5-10 seconds. I also have a kernal panic today which is the first in 2 years..
The sound output in my Macbook Pro has been going in and out now for a number of months. And yesterday it finally got stuck on "Digital Output" meaning when I take out headphones from the jack, the internal speakers do not work. I am planning on taking it in and wanted to know, since I am still under warranty will Apple repair it, or give me a new one?
when you're recording, will the sound quality of the dual function line in audio port on the 13" be as good as the dedicated one on the 15"?
edit: the reason I'm wondering is because I want to convert old collections of vinyl records into digital copies at the highest quality possible and need to know if the 'line in' on the 13" will work good for that.
Line-in external tape recorder produces VU sound level fluctuations but the sound doesn't come out the internal speakers. iTunes and Internet sources play OK.
I have a 2nd monitor and hooked up my xbox 360 to it. I have it connected through HDMI and then have a regular audio jack going from the monitor to my Mac Pro. When I open up my sound preferences and select: Line In - Audio Line In the "Input Level" bar goes up and down meaning it is registering or hears the sound coming from my xbox.
For some reason though, the sound will not output from my Mac Pro. My speakers which are connected to Line Out: Built In Line Output still outputs sound coming from my mac pro but it won't output the sound from my 360. Is there a remedy for this?
So quickly again.
Line In - Audio Line In is "hearing" the sound from my xbox 360 as the "Input Level" bar goes up and down.
Line Out - Built In Line Output still outputs sound from my Mac Pro but not the 360.
I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?
Just set up a new Mac Pro (8-core) and plugged in my old M-Audio powered speakers (about 10yrs old but still going strong!). I use a mini-jack splitter cable that outputs stereo RCA to the speakers, plugged into the speaker port on the nMP. There is a constant, low hum coming out of one of the speakers; it sounds a little like CPU noise and it is NOT affected by volume settings from the Mac or the speaker knob. It's the right-side speaker which is unpowered, connected to the left unit via speaker wire (the left unit has the power switch and audio inputs and is not affected.)
I've tried moving the speaker wire up and away from power cables (two Dell monitors directly next to the speakers) but that doesn't work; it doesn't sound quite like a DC hum anyway though. The speakers aren't heavily shielded (they usually pick up interference from an iPhone placed too close) so maybe it's always going to be an issue. I used to have them plugged into a 2006 Mac Pro via an analog mixer which I've removed from the chain.
Basically im turning my room into more of a home cinema, and was looking to use my laptop to play movies into a TV, and sound through a surround sound. I was simply going to use a mini toslink to optical adapter which would plug into an av reciever. I was just wondering who else does this, and what is it like? Is the audio quality okay? Can it sustain high volumes? had any troubles? what does it use, DTS or something?
I just bought a Mac Pro. I immediately installed 2 GB of RAM and four large hard drives without even booting the computer while it was stock. Anyway, the machine is connected to JBL Creature speakers via the (analog) line-out port. However, unless I also have the headphone port connected to the speakers with a splitter, I get a really high pitched squeeling regardless of volume level. And yes, my sound preferences are set to the analog line-out setting.
Also, when I have both ports connected to the speakers and the squeeling is gone, I get hard drive read and write noise through the speakers. It's most apparent in Final Cut Pro and Motion. I'm hoping that, if it needs to be repaired, Apple will go through my local Apple-certified shop (not an actual Apple Store) instead of having to send it in.
I recently got a brand new 17' unibody MacBook Pro. Although it was brand new, there have been a flare ups. The last time I had the problem, (note: it is always while watching a YouTube video) this is what I captured before quickly closing the window. http://grab.by/1Gjt
That was New Years day. The first time I experienced this problem, I got nothing on the YouTube player and while skipping throughout the video to get it to stream, a noise that can't even be explained screamed out of the computers speakers. Today, I just had the same problem. I have no clue what it is except that I do know it comes from the speakers. Could anyone elaborate on if something similar has happened to you?
