Line out sound source dies at sleep

wondering if anyone else has run across this -- i'm using harman kardon sound sticks 2 as my sound out, and the sound just won't work upon wake from sleep. if i unplug the speakers' power source and replug, the machine finds them again, and everything's fine. anyone? anyone? bueller?

FINALLY, I found a topic on this.
I have the same problem with the internal speakers - wake from sleep, no sound. I have to plug in my earbuds to the headphone jack and remove them, then the iMac's speakers play audio immediately.
I'll try the update to 10.5.1 and see if the issue gets resolved.
Cheers and good luck!

Toshiba nb505 dual monitor & line out sound

Hi all, I've gotten a toshiba recently. Everything is working perfectly right out of the box--except the dual monitor setup (w/ a maxent moniter as the secondary).
The maxent works fine w/ other laptops, so that item is not the problem. It has to be the toshiba. When the toshiba starts up, the images like the toshiba logo and very initial windows splash will show up. But then it stops, and the maxent just goes back to its blue screen. In addition, the line out sound will only play right speaker sound (on the maxent and other devices) . . . but w/ headphones it is fine.
Please advise on any suggestions. Drivers are all up-to-date and windows updates are good, so I'm really lost.
This should be basic, so it's pretty disappointing this isn't working. Thank you!
system info:
toshiba nb505-508BL
OS Windows 7 Home Premium, 32 bit

update:
sound line out: Apparently the speaker on that maxent monitor flat out just doesn't work anymore--no matter what input. And I suppose my hearing is such that it may well have been like that for a while, as it's unlikely the toshiba just happened to blow out that speaker these few recent times I hooked it up to the maxent (as there was no such indication, like a pop or the like).
dual monitor: Testing w/ other monitors successfully, this seems to be more a compatibility issue w/ the Maxent itself (though there may be other monitors it won't work w/, too). So I mostly wanted to put this out there still if wide compatibility w/ dual/external monitors is something that others are considering this sys. for, too. . . .
Otherwise, the netbook is working fine, and I have no other complaints--though I found this dual monitor issue rather disappointing (still I feel it's quite possible that a RAM upgrade may resolve this, since others have cited that upgrade as rather essential for getting the most out of this little sys., but I haven't tried that yet).

I use line out sound but the sound does not stay on when I start up

I use external speakers with my Mac Pro. However, since I upgraded to Yosemite (with latest upgrades), I have to use the desktop icon to turn on the sound every day. Alternately, I can uncheck the mute box in Preferences. Somehow, the mute button is set when I start up. How can I keep the mute button off?

How long do you wait for the display to come up? Can take several seconds during the boot process. Have you tried a safe mode start by holding the shift key down during startup?

Keyboard line out and griffin imic incompatibility?

I'm getting horrible background noise when I try to record my keyboard (Yamaha PSR-225GM ) headphone line out through my Griffin iMic into Garageband. I assume it's a level issue but even the keyboard volume control won't fix the problem nor will system settings for the input device. My Sony stereo mic into the same iMic input sounds fine. Headphones attached to the keyboard line out sound fine too so I don't believe it's a quality problem with the line out. Can one not use a headphone output into the Griffin iMic?
If not, anyone got suggestions for higher quality audio input into the iMic flat panel (e.g. some USB box) that's compatible with various audio equipment (mics, keyboards, guitar amps, 1/4" and 1/8" and RCA plugs etc.)? The iMic has served me fine, but maybe it's time to start looking for something higher quality, and more versatile. Thanks.
By the way, anyone know why sometimes there's a delay (half second or so) between audio in and the monitors in Garageband, and sometimes not? It makes performance nearly impossible when there's such a big delay.

tell me if I'm on the right track on the
following theories (I don't know if the following are TRUE):
I'll do the best I can...
1) The quater-inch headphone output from the Yamaha
keyboard is neither "balanced"
Correct, the headphone-out is not balanced. A balanced output uses 3 wires, a graound, a hot, and another hot that's 180° out of phase with the first. This is a neat trick in that two signals 180° out of phase with each other cancel each other out sp you get zero signal. In the case of a balanced out if noise is introduced, it is in phase on both cables. On the other end when the signal on the out of phase wire has its phase flipped, your original signal is now in phase on both legs, and the noise is 180° out of phase with itself, and thus is canceled out.
nor impedance matched
to the Griffin iMic.
The impedance is not a problem here. As I understand it, the headphone-out is High Impedance, and so is the iMic's In.
(I'm using a 1/4" to 2.5 mm
converter cable). I am possibly getting radio
interference (I DID get a local radio station when I
touched the plug right!!) and degrading the signal
because of these two issues.
Possible. A Low quality cable and or adaptor could offer an entry point for noise.
2) It may be necessary to put the signal from my
keyboard's headphone jack into a DI (direct box) to
get impedance matched to mixer levels - the levels I
assume the Griffin iMic expects.
No, this shouldn't be true. A headphone-out is actually much hotter than a Line-In, so the level should be able to offer more than enough signal, and the impedance is matched.
3) I'm HOPING that a high quality audio-to-USB (or
firewire) input box can perform the job of the direct
box.
It could, but the weak point I see is that you're stuck using a headphone-out instead of a Line-Out. I don't think a DI box is going to help any in comparison.
Hmmm, I just glanced at your computer list. Doesn't the iMac have a Line-In jack? Have you tried skipping the iMic and going straight into the iMac?
Finally, if anyone can give me the list of equipment
in order from a keyboard to Garageband
I think it could be Keyboard -> Mac
Other combinations would just be sticking an interface between the two (Keyboard->interface->Mac)

Intel imac line out hifi trouble

Hello all, i just tried an unsucessful search and decided to just post my question. I bought an imac intel duo a month or so ago. I was not impressed with the speakers so i bought the apple hifi to go with my ipod and also plug into my imac. Everything worked fine for about 3 days. Then any audio output coming from the computer is messed up. It is just garbage coming over the line. I unplugged the hifi and it plays fine with the ipod and the internal speakers for the imac work fine. Also when i plug in a pair of head phones the imac line out sounds the same garbage as the hifi. Can the line out jack break on its own. Also i live in north louisiana and the closest apple store in 3 hours away in dallas. I have the apple card plan for 3 years, but i really don't want to drive all the way to dallas. If anyone has heard of this or has a fix please email me at [email protected] I can't guarantee you i can find this thread again to read the response if i get any.
bye and up till now i have loved my imac

I bought the applecare package, and they are sending someone out to take a look. I removed parallels and windows xp virtual computer, Although, i would like them back, if they caused the problem, it didn't correct it when parallels when bye bye.
Anyway, hopefully this applecare rep, will be a smart fellow and know his stuff, and not rip apart my machine. I am kinda worried. Anyone had any experiences with applecare outcall tech's. Let me know, i always prefered the incalls better myself, but this is my first time again.
Don't know if anyone got my lame pun, but any feedback about applecare would be apprecieted... And i will update the result and if the problem is solved, i will change the status of my question to answered.

After selecting Line Out in preferences the next boot sends sound to internal speaker

How can I get Line Out to to stay as default audio out preference?

I have a very similar problem that occurs to my computer where I will return to my computer after it has gone to sleep, and sound controls do not work. All systems tones come from the internal speaker, as well. After doing a Google search, I came up with an AppleScript to make it change to the internal speaker, then go back to the line out. The script works with the default listings in the sound preferences panel, but you should be able to change it to whatever is listed in your Sound preferences pretty easily. To do it, go to Applications, Utilities, AppleScript Editor. Once there, paste in the code below into the top box. Then do a file, save as. I would change the File Format to Application and save it on your desktop. You could create then a shortcut in your dock to launch it whenever sound is not working right. The script follows this (copy it all from the first tell to the quit):
tell application "System Preferences" to activate
tell application "System Events"
get properties
tell process "System Preferences"
click menu item "Sound" of menu "View" of menu bar 1
delay 2
set theRows to every row of table 1 of scroll area 1 of ¬
tab group 1 of window "sound"
set theOutputs to {} as list
repeat with aRow in theRows
if (value of text field 1 of aRow as text) ¬
is equal to "Internal Speakers" then
set selected of aRow to true
exit repeat
end if
end repeat
end tell
end tell
tell application "System Events"
get properties
tell process "System Preferences"
click menu item "Sound" of menu "View" of menu bar 1
delay 2
set theRows to every row of table 1 of scroll area 1 of ¬
tab group 1 of window "sound"
set theOutputs to {} as list
repeat with aRow in theRows
if (value of text field 1 of aRow as text) ¬
is equal to "Line Out" then
set selected of aRow to true
exit repeat
end if
end repeat
end tell
end tell
tell application "System Preferences" to quit

Clicking sound on line out

Does anyone know why I am getting a clicking sound (about 80 bpm) on the line out port but not on the front output port. This is a 3GZ mac pro running OSX 4.9. Also, what's the proceedure for getting the machine fixed while still (just barely) under warranty? Hopefully it's just a software problem. Thanks, Ron

Do you have your audio cables running close to strong power sources, power cables etc? This can sometimes create noises similar to the kind of thing you're describing. That would be the first thing I'd want to rule out before checking the hardware itself.

MacBook: line out noise when sleep mode

Hi,
I have my MacBook hooked up to my hi-fi system with a line-out to cinch cable. whenever the macbook enters sleep mode or is turned off, a very loud noise is generated, as if I would have plugged the cable right off the computer.
Is there any way to circumvent this annoying noise? I fear that the permanent explosion-like-sound might damage my speakers.
Thank you!
Mark

thenk you for the answers so far. What I am doing at the moment is not perfect, because it does not work when I forget one step:
-I activate sleep mode only manually now
-before, I switch off the receiver (otherwise, the loud "pop" noise is still there)
I will try with a better quality-cable, but I can only imagine the sound quality of the loud "pop"-noise to be 'crystal-clear' with a better transmission (optical cable doesn't work on my system)
Thank you,
Mark

No sound out of back line out MacPro Bootcamp 3.1 Windows 7 64bit

No sound out of back line out speakers.
MacPro Early 2008
Bootcamp 3.1
Windows 7 64bit
Realtek HD audio driver.
I have speakers plugged into the back line out.
They work in Mac 10.6.4 (as always) and in Parallels 5 Windows 7 using Bootcamp partition.
All other jacks work. In Realtek driver it shows nothing connected to that jack.
Anybody else have this issue?
Anybody else have solved this?

Anyone at all?
Even if you don't have the issue yet have a similar setup. Maybe I can figure out if there's a driver update I may need.
BTW I KNOW others have this as I've seen this mentioned on other forums. What I do NOT know is whether it's "everyone" or there's something about systems that don't have this issue, I need to follow.

HP-HDX 18t w/ Vista 32 won't retain default sound source after sleeping

That about sums it up. It's a brand new HP HDX 18t laptop running Vista32. It's setup with HDMI to our flat-panel TV and we have a Turtle Beach Audio Advantage-Micro usb card so we can use the SPDIF digital audio passthrough to get the 5-1 dolby sound to the surround sound receiver. It all works as it should playing Blu-Ray DVDs as well as any other sound... no problem. If we completely shutdown and then turn it back on it's fine. But if we put it into sleep or hibernate mode instead, then it loses the default sound source setting we've chosen (SPDIF) and we have to manually reselect it. Same thing if we disconnect it entirely. But that makes some sense and we don't plan to do that a lot so it's not as big a deal.
Thanks for any insights.
I hope I've provided enough info.

I have the macbook pro 13 inch 2,66 Ghz april 2010 model.
I can't get my headphones to work in Windows 7, 64 bit(bootcamp). It seems like the cirrus logic CS 206 A (AB13)drivers are the problem.
I have installed the latest drivers, have set the headphones to standard audio device (I don't know how you call that option in english as my windows is dutch). I also disabled the macbook speakers, the digital audio device and nothing seems to work. I can play music through my macbook but can't play it through my headphones. In mac osx there is no problem at all doing this, the problem is only in windodws 7.
It's very annoying because I would like to play some games.
And yes I've installed the 64 bit drivers.

Line out and Sound Effects revert to Internal Speakers when I reboot. Any suggestions?

I have an early 2008 Mac Pro that runs fine under Yosemite. The Sound preference panel worked under Mavericks, but now I must open the Sound panel and manually change the output for both Output and Sound Effects from Internal Speakers to Line Out after a reboot. This is irritating and is becoming more so.
I've zapped the PRAM with no success.
Would an AppleScript app on startup work? I can't seem to find any appropriate commands in AppleScript that affect these parameters.
Any help appreciated.

The script doesn't seem to work on Yosemite. Trolling around in the library, it appears that "audio" is now "sound," which would explain the file not found.
Or am I missing something?
Suggestions?

Guys ... I have a 2008 MacPro running the current Yosemite. I also have installed the sound amp called "BOOM!" I have the Sound set to Line Out which should have the computer boot up to BOOM! Instead, it boots up to the Internal speaker. What's up?

Hi Folks ...
I have a 2008 MacPro running the current Yosemite. I have installed the recommended upgraded video card, but the sound is as it was new. I also have installed the sound amp/graphic equalizer called "BOOM!" I have the Sound set to Line Out which should have the computer boot up automatically to BOOM! and thus to the external speakers. Instead, it boots up to the Internal speaker. According to the folks at "BOOM!", this is happening to others who have similar Macs. They can't find any explanation within BOOM!, so I am turning to you all. Any ideas?

Hi Kappy ...
Sorry, I guess I didn't state the problem very well.
I don't want the computer to boot up to the internal speaker. I want it to boot up to the external speakers. However, even though System Preferences is set on Line Out, when the computer boots up or reboots, it erroneously goes to internal speaker. So, every time I boot up, I have been going to System Preference/Sound and clicking on Line Out. From that point on, everything is OK until the next boot up. It is a small annoyance, but annoying all the less. The simple explanation seems to be that when the computer is shut down, it does not hold the setting for Line Out and resets itself to Internal Speaker. How do I change that behavior and get it to go to Line Out whenever it boots up?

Enabling same Line out on my sound card (XFI Music)

3Enabling same Line out on my sound card (XFI Music) Hello all,
This must be possible! My main problem here is that I cannot find anyway to clone my main output, let me explain.
I have my digital piano plugged into Line in
I have my headphones plugged into the first Line out (these work fine)
I have my TV (plugged in via 3.5mm jack) plugged into line out 2 (the one next to the green one)
My TV is setup as a second monitor so I can watch films etc. All I want to do is get what I hear in my headphones on the television at the same time. I don't want to have to plug my TV into the green lineout everytime I want to use it.
While we're on the subject, is there anyway I can remap the inputs, at the moment if I wanted to plug in my digital piano and a mic at the same time I can't. The irony is I upgraded from my absolute rubbish Realtek AC97 onboard audio device which could do all of the above. Surely this is possible?
Any help would be appreciated.
Regards,
Trinitrotoluene

Satellite L675 - line out echos sound

I am a senior citizen. I have my laptop connected to my big screen tv - for ease in seeing (eye problems). Also, I stream a lot of movies through netflix. The computer is about a month old. The first 2 weeks everything worked great. Then, the sound started coming out of the computer speakers as well as the tv - which gives an echo (they are slightly off sequence). Makes it nearly impossible to watch movies. I have uninstalled my sound card and rebooted; I have unplugged the line out and rebooted. The audio "line out" is checked. But, when I do a sound check - I am STILL getting sound from the computer.
Any suggestions????
George, in Nashville

I have a follow up to the issue that George is having. I have the same model laptop and had the same issue. Now, I do see that you have the option to select either "Headphone" or "Line out" when connecting the audio jack to the TV. When using headphones, I can limit the output to the TV, and the "Line out" will have output coming from both the laptop speakers and the TV. However, and I may be mistaken, but isn't the audio quality better on the line out setting? Isn't additional information filtered when you go to headphones? It may be an incorrect perception on my part, but I feel like i'm getting higher quality audio out of line out. Because of this, I would rather have the laptop set to "line out" while still shutting off the laptop speakers.
Any thoughts? Anyway to achieve this?

Audio problems - soft sound, no line-out detected

ok, so a number of things went wrong with my computer.
it was working perfectly, and i opened garage band up to record music, and all of a sudden, no sound was coming out. at this stage i was using the line-out to my stereo amp. it also wouldnt let me change the volume and came up with the circle-with-a-line-through-it symbol.
i did all the standard stuff, close garage band, play with the settings, go into system pref. restarted it, and then it was making some strange fuzzy noises, and system pref. said that no audio devices were detected, so i restarted again. now i only have built-in output detected, and its very quiet, even on full volume, the volume and mute controls all work.
so thats all of my problems. im currently running OS X 10.4.10 on an intel-based iMac.
thanks

Folks,
on Nov. 29, 2007 we have begun shipping a revised PocketDock Line Out USB, which is now iPhone-enabled. We have also revised the 1/8" stereo plugs on the included cables, so they are now thin enough to fit the iPhone’s recessed headphone jack.
Note that not all retailers might have the newest stock, so if you want to be on the safe side, either ask for which revision they sell (the iPhone-option is mentioned on the packaging) or order directly from http://www.sendstation.com.
