M-Audio Revolution 7.1 PCI Static in speakers

I have a Blue and White Power Mac G3 with the DayStar 600 mhz G4 processor upgrade, M-Audio Revolution 7.1 surroundsound PCI card and Creative Labs Inspire 7.1 surroundsound speakers and I'm running OS X 10.4.4. My speakers sound fine in stereo only mode but the minute I turn on the surroundsound I get this nasty cracking type of static in the speakers. The surroundsound works and they sound good inbetween the cracking but the cracking just won't go away. I've had these speakers and sound card and processor for about a year or so now and they've been doing this the whole time. I download every driver update that comes along hoping that each one will be the one that fixes the problem but no such luck. Has anybody else out there had this problem? Or had this configuration with no problem? Or better yet, had the problem and found the solution?

Having sound distortions in games with M-Audio Revolution 7.1

I'm having sound distortion problems with a couple of games. I think this started a few OS X updates ago, but not sure which one. Two known games are Quake 3 and Quake 4. When I run either of them, the sound is deep and distorted.
I'm sure an update of OS X broke m-audio's revolution driver. I currently have driver version 1.4.1. I only have distortions when sending sound output to my sound card. Sound sent to internal speaker comes out fine. I also tried with a freshly created user and freshly reinstalled driver & prefs. Same problem.
I've tried M-Audio's site with no luck for solutions. It's been a year or so since they have updated it.
Is anyone else having similar experiences with their M-Audio Revolutions?

Substitute for M-Audio Revolution 7.1

Hello-I'm planning on purchasing a new 24" 2.8 GHz iMac; one problem I think I'm going to have is somehow connecting the new machine to my Klipsch ProMedia Ultra 5.1 speakers. I presently use an M-Audio Revolution 7.1 in my old G4 to hook up to this speaker system; works great.
Is there an external box of some kind (other than a home theater receiver and lots of adapters) that will allow me to connect the iMac's digital out mini jack to this speaker set? (It has the traditional three 1/8" cables, to hook up (1) front R/L, (2) surround R/L, and (3) subwoofer).
I may have to use an audio receiver to do this; but perhaps there's an interface available that I don't know about . . .thanks in advance for any suggestions.

Well, I guess I can now answer my own question; I've discovered the Griffin FireWave, a single box with FireWire 400 in (and a 2nd FW400 pass-through jack), and 5.1 audio out, via the 3 1/8" stereo jacks that will connect to my speaker set.
Picked one up on eBay for $60.00. No AC wall wart, either; it supposedly gets enough power from the FW port. I'll post on how well it works once I get it hooked up.

Xp 64 m audio revolution drivers?

any one seen the xp 64 m-audio revolution drivers out there? or anything compatible? It sucks that my xp 64 doesn't have sound

The m audio sound card is suppose to be better for sound quality. But I guess if I use the spdif it wouldn't make difference. or would it?

Audio output will not work on external speakers. Internal speakers will work. What do i do to replace audio output slot

Right click your volume icon in the notification area and select "volume control options". From there, you should be able to select the external speakers.
I hope that helps!
Best of luck,

Audio output changed to 'Digital Out' and speakers don't work! Please help!

I'm not exactly sure what's happened, but after starting up my macbook pro, my speakers/audio haven't worked.
The volume control in the menu bar is inactive (looks light grey) and in the Sound menu, I have no option for output devices except for 'Digital Out' - there is no other option for 'external speakers' (as per usual) or anything!
I can plug earphones in, and sound comes out fine... I don't know what may have happened, but I'm really worried - I use my MBP for home & work; I need my speakers to work!!
If anyone can offer any advice, I'd be really grateful. Thank you in advance.

Talked to Tech Support about this when my machine locked up in this same fashion. There's a little "door" inside the headphone jack that can get stuck in the open position and keep the audio from switching back to the internal speakers / stuck in the digital (optical) output position...
The solution: the iPick... It's a toothpick, but if you use it to poke around inside the headphone jack until the little door gets unstuck, it becomes an iPick, and a box of them are very expensive, but they come in lovely colors and are very intuitive to use...
I'm not kidding... Stick a toothpick (or other non-conductive small stick) in the headphone jack and joog it around until it releases the little door...

I have lost all audio on both my internal and external speakers.

I have lost audio on both my internal and external speakers. I have checked the System Preferences when my external speakers are plugged in it is acknowledged. When using internal speakers they are also acknowledged. Sound volume on Preferences is on and fully high. The sound buttons on the keyboard do not work and the sound level is now locked in at full sound and cannot be adjusted using the keys. The System Preferences shows that Mute is now checked and I cannot uncheck it. What should I do to get my sound back both internally and externally?

Repair permissions & restart.
Check your settings in the Audio Midi app which is located in the Utilities folder.

Trick/Tip: Open up GarageBand if installed then, open a program (optional).

=====================
Repairing the mysteriously muted Mac
The background on the issue is that there’s a small sensor switch inside the headphone port. When you insert a headphone jack, the sensor understands what's what and changes the sound output setting to Headphones. If you insert a jack for digital audio output, the device changes to Digital Out. When you remove the jack completely, it should read Internal Speakers.
The spirits tell me that there’s a very good chance that you recently had something jacked into this port—a set of headphones or a cable leading to powered speakers, for example. When you removed the jack, something in the port prevented the sensor from tripping correctly. That’s why you see Digital Out instead of internal Speakers.
The solution is to force the sensor to do its job. The safest way to do that is to simply run a jack in and out of the port a few times. Much of the time, this takes care of the problem by correctly tripping the sensor. If that doesn’t work, there may be gunk in the port. Before turning to more invasive techniques, get a can of compressed air, attach the small tube that fits the nozzle, and blast a few shots of air into the port. With any luck, that should dislodge the gunk and the port will operate as it should.
If that doesn’t work, find a foam-tipped swab that fits (electronics shops generally carry them), dip it in rubbing alcohol, and gently insert it into the headphone port in an attempt to wipe away any stubborn gunk. I recommend foam rather than cotton swabs because the cotton variety might leave threads behind. (This same technique works well with misbehaving headphone ports on devices such as iOS devices.)
It's possible that gunk has nothing to do with it. Rather, it may be that the switch just needs a subtle nudge. If a jack or swab doesn't work, I've heard of people successfully resetting it with a deft poke of a toothpick.

Does airport express stream directly to wireless speakers or does it need to be connected through an audio cable to an amplifier before the speakers

Does airport express stream directly to wireless speakers or does it need to be connected through an audio cable to an amplifier before the speakers?

I got an additional question bout this topic:
is it possible to use both at the same time? in my case cable-connected speakers in the living-room and an Airplay-speaker in the bathroom and/or kitchen?
so I select the Airport Express as Airplay-Output on my iPad and from there it's shared via cable AND wireless? this would solve the problem of being able to only select ONE Airplay-Output on my iPad at the same time...

10.4.10 Audio Popping Issues: Information Check with Internal Speakers

For people with internal speakers, or those without subwoofers: Please read all the way to the bottom to find a test that will determine whether you are also having audio problems, even if you can't hear pops.
We've had a lot of discussion about audio popping due to 10.4.10, and the evidence indicates that the audio circuitry is going to sleep to conserve power, even on AC-only computers like the iMac, Mac Mini, and (at least one) Mac Pro. Some people claim to not have this problem, but I'm wondering if they just aren't noticing it.
Having external speakers with a subwoofer, set to high amplification, are key to obvious detection of the problem. Let the sound subsystem go idle for 30+ seconds (wait a minute with no audio, just to be safe), turn up your external speakers really loud, and cause the computer to make a sound. You should hear a burst before the sound plays. If you repeat the sound, you won't hear the burst. This is the sound of the audio circuitry powering on, and the speakers are amplifying it.
About 30 seconds after the sound finishes playing, if you leave the volume of your speakers turned way up, you should hear a "pop" as the circuitry is powered off. Then, playing another sound will recreate the burst.
I haven't been able to hear these sounds with internal speakers, either on the Mini or iMac. But the problem still exists, and it is detectable... if you know what you are looking for.
The burst of the audio circuitry turning on also causes a delay in the audio. The delay is a noticeable fraction of a second, an it can easily be detected if you have a repeatable source of sound. I like Terminal.app, because I use that application all day, every day. Here is how you can check to see if you are also subject to the audio problems:
1. Start Terminal.app (in the /Applications/Utilities directory).
2. Wait one minute for the audio circuitry to shut down.
3. Without typing anything else, very quickly strike and release the Backspace key.
4. If you pressed the key all the way, the program should have caused a beep. However, if the audio circuitry goes to sleep, the beep should occur after you have moved your hand off the key. This is because the circuitry takes time to power itself on before playing the sound.
5. Now, quickly strike the Backspace key again. You should notice that the sound is produced immediately as you hit the key, without the delay you just witnessed.
6. Strike the Backspace key repeatedly, to confirm that there is no audio delay. Do this about once every second or two. If you press the key too rapidly, not all of the presses will produce sounds... this behavior is not related to the issue we are testing.
7. Wait another minute for the audio circuitry to shut down, and strike the Backspace key once more. You should again observe a delay between your strike and the sound production.
If you witness delays like this, your audio circuitry is also going to sleep, and you are having the same audio problems as the rest of us. However, either because you are using internal speakers, or because your external speakers don't have the appropriate response, you aren't hearing the same bursts and pops as the rest of us.
Please try this test, and report here. I want to build a list of people who previously couldn't hear the sounds, but still have the delay. This might give us a better picture of the scope of the problem.

Re: 10.4.10 Audio Popping Issues: Information Check with Internal Speakers
Your analysis of what is happening is right on.
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on your laptops.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".
Crikey!

How do I play audio from my headphone jack and internal speakers?

How do I play audio from my headphone jack and internal speakers at the same time ? I have a splitter for my audio jack so that when i connect up my second monitor I can have it so it also plays audio as well as anything else i have connected into the jack but how do i let the internal speakers emit sound at the same time?

Hello,
If you mean the internal speakers in your Mac, you can't play audio through them at the same time you have anything plugged into the headphone jack. When you plug something into the headphone jack, it disconnects the internal speakers.

Export Audio to movie causes loud static

Hello,
If I import a movie (.mov) file into Logic pro 9, add some extra music tracks and then try to "export audio to movie" to my desktop, when I open the exported file in quicktime player I get horrible static. I am also running Logic in 32bit mode.
Just on accident I found that if I export the file to my SDCH card that i use for my Canon T3i camera and not to my Desktop the file opens fine, I hear the extra tracks I added and the actual audio of the original file.
Can anyone explain why I can't export the file to my desktop without the file opening with static?
Just for a bit more information, I can also export to a jump drive with no problem. Does the the way my hard drive is formatted have anything to do with this feature?

Mac HD: Mac OS Extended (Journaled)
Thanks
Darian

What is really odd is the Jump Drive and Secure Digital card are both formatted Fat32 MS-DOS, while your Mac drive is formatted (correctly) as Mac OS Extended.
Go back to your original formatting... what happens if you move the noisy file from your desktop to the jump drive and play it from there, is there still static, if so that eliminates a playback problem and places it on the record function. Best to narrow things down.
De-Select Floating point and set the sample size to 16, leave everything else the same.

Audio CD Burn Turns Into Static After Beginning of CD

I'm noticing that after I burn an audio CD from my MacBook and then take it to my car's CD player (or any other non-computer audio CD player), I hear progressive static as the disc moves down the playlist. By the end (if I make it there), it's almost all static overtaking the music. Has anyone else experienced this, and if so, how did you fix it?

hello folks! I have the same problem. At about half to three quarters through a cd, while playing in the car stereo, I will get a crackling static that basially makes the cd unplayable from that point on.
Shall we try to debug this?
1) Are we all burning in iTunes? I am.
2) What setting do you have for burning speed? Mine is set at maximum speed.
3) What kind of media are you finding this with? For daily burning use, I use TDK CD-R 52x 80min/700mb.
So the first thing I'm trying is to lower the burning speed.
I'm assuming that since it shows 24x as the highest speed, that it is the highest speed the drive can use. I'm trying 12x first to see if that has any effect.
Let's also make sure we are using an internal MATSHITA DVD-R UJ-857E drive.
I have been trying to locate a good CD/DVD diagnostic tool, but can't find the Apple Hardware Test CD that came with my computer. Any suggestions on second party software?
