Audio through Line Out a bit muffled and boomy

I am playing music in iTunes through my old Sony amp and Wharfedale speakers connected with all-right-quality speaker cables.
In iTunes I have to play around with the equaliser to get acceptable sound quality but it will still not be as good as when I play a CD on the CD-player that is connected to the same amp.
I also tried using the headphones output but the result was the same.
Any suggestions on how to improve the sound?
/p

Make sure "Sound Enhancer" is turned off in iTunes' "Playback" preference.

No audio from line out

hi,
my audio works with internal speaker but nothing from line out when selected in sound controls. In audio midi setup, i do not appear to have any control on the master volume for line out, (its stuck at 0) i am suspecting a driver problem - May have been overwritten or deleterd when I tried to install Parallels 7 - now uninstalled
cheers

What do you have connected to line out?
Line out is designed to be the input to amplifiers and not speakers.

Audio alone line-out good...Audio w/video line-out weak

Trying my new 5th gen iPod today on my home audio system.
Using a 3mm miniplug to the line-out on the Universal Dock, audio by itself is very good, bumping the LCDs on my old Sansui equalizer all over the place.
Using the same connection and playing back Michael Jackson's Thriller video, the audio is so week that it doesn't even bump up a single LCD. (Note: volume is set to max on the iPod.)
What gives?
iMac G4 20-inch flat panel Mac OS X (10.3.9) 30GB iPod; 60GB iPod, both 5th Gen models

You might want to right click that file in iTunes and go to get info. Click the options tab. See if adjusting the volume level there and then syncing your iPod helps.

How do you route the line-in audio to line-out on Mac Pro (10.6.8)?

New to Mac. 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 explicity route the audio. Probablly missing something simple. Any help would be appreciated.

You can do this without buying or using 3rd party s/w. Use GarageBand this way:
1. New, Empty Project
2. On the next screen, choose:
     a. Audio, Line In
     b. Input 1+2
     c. Check the "I want to hear my instrument as I play and record" option
     d. "My instrument is connected with:" - Built-in Input
     e. "I hear sound from;" - Built-in Output
     f. Click "Create"
3. You should immediately hear sound; you don't have to record anything.
4. If you don't see green bars on both the Audio 1 track and the master volume (top right), something is either wrong with your input or the steps didn't work for you. To redo the steps, choose "Track, Delete Track" from the menu and try again.
IMPORTANT: Make sure that all of the needed volume controls are up high enough to hear something:
1. Audio 1 volume and Master Volume sliders in GarageBand
2. Volume slider on Apple main menu, speaker icon not muted
3. Volume on input device (e.g. iPhone)
See how you go
P.S. I do it on a mac mini but it shouldn't be any different

ITunes ONLY plays through internal speakers, system plays through line out

I have my system setup to play through my stereo. I launched iTunes today and it gave me the "accept terms & conditions" as if I had just downloaded a new upgrade (I didn't - have been running 7.4.2 perfectly since Sep 10 2007). I agreed, iTunes starts up ok with library intact. BUT; When I press play, the sound started playing through my skype phone! I plug out the skype phone and it plays through the internal speakers.
I checked sys prefs and it's ticked for line out, and, surely, when I press the volume button it adjusts through the stereo speakers (as does everything else except iTunes now).
I tried playing with the skype phone settings but they were all fine.
Does anyone know what's happening here?
edit: strange - I quit iTunes and it asks me "keep new settings or old settings". I keep old, restart iTunes and it plays through the speakers again. There are no settings in iTunes to change output as far as I can see. I thought I'd leave this post in case anyone else comes across this. odd, but sorted ?

sorted itself on restart

No audio from line out port

hello, i am using plug-powered speakers on my powermac g5 using the front headphone port. the speakers work fine this way, but when i use them on the line out port in the back, i get a high pitched hissing sound and very quiet audio. the computer detects the speakers, and i am sure i'm using the output port ] ))) and not the input port >o<. how can i get the speakers to work from the line out port so i don;t have to use the front headphones port? thanks!

i have a question. if i have standard apple ipod headphones, and use them on the rear audio out port, will i get the same sound as the headphones port on the front?
i still can't get this to work. i'm starting to believe this is a hardware problem, all the settings are identical for audio out and headphones in audio MIDI setup, but i'm still not getting any sound when i use the rear.

Intermittent noise through line out + AJA Kona

I have a MacPro Dual Proc 2.66 dual core that's about 18 months old, with an AJA Kona LHe card that I use for film and audio editing. The Kona feeds an SDi input JVC Reference Monitor and the AJA KL interface feeds my Mackie mixer. The Audio line out also goes to the Mackie, so that I can monitor iTunes and Amadeus via AJA or Line out, depending on my process.
I have started noticing a really low intermittent hum that arrives at the mixer via the AJA KL box or from the analogue out. It is usually not there when I first start working but after an hour or so it starts, each burst lasts about 3-4 secs and is very low, painful to the ears.
I've tried plugging earphones in to the front socket and there is no hum at all.
I've tried linking fan activity to the hum without success.
I have SoundStiks for Desktop audio and there's no hum there either. I prefer to work with headphones when editing so I really want the AJA sound to be clean but can't fathom where the sound is coming from. Any ideas?

HI I am having the same problem with HUmming sounds coming from my Mackie mixer also. But the sound is constant and wont go away using the ajay card.
selecting the outputs to Internal speakers, or LINE OUT, or Digital out. the system using headphones I do not hear the humming only when selecting the AJA kona 3 card OUtput..I hear it with headphones and with external speakers.
When the Mac PRO QuadCore- Intel Xeon 2 x 3Ghz restarts the sound is still there during boot up and even if the system is shutdown.as long as the RCA cables are plugged into Ch1 and CH2 you will hear humming. BUT if you unplug the RCAs from CH1 and CH2 the hum stops.
I tried using a different wall outlet for power for the Mackie mixer and the external speakers I still had HUM. I tried another rackmounted AJAK3-Box still there was a HUM.
I am running out of ideas.
THis card has been in production in our environment for over years now. BUT the system recently was relocated to a new office...
I think it has something to do with the AC power in this area..
Is there something wrong with this card? Could there be a driver update? Have you resolved your issue YET?
Any help would be greatly appreciated.

X-Fi Titanium only Mono output through Line-Out

Hi,
I have a problem with my x-fi titanium card. Since yesterday the output of the line-out is only mono. So the sound is always the same for right an left channel. I tried this in the mixer menue where you can test each channel if there is sound.
I already re-installed the newest drivers and changed PCI-E slot on my motherboard. The strange thing is in audio creation mode of the mixer I can see different amplitude for left and right channel of the output while testing.
After testing this whole thing I assume the amplifier of the card is broken and giving out the same signal to both channels.
Anymore suggestions?
regards,
Mik

are you using a mono cable with the card? Your card could very well be outputting stereo, and if you use a mono cable, you will end up with 1 channel sound.
Have you checked your mixer to make sure that you do not have the balance slider set to the left or right?

Incoming audio on iphone 5s call is muffled and too low to hear

Just activated iphone 5s has an audio problem. Incoming calls audio is muffled and to low to hear.

Stop restoring the new phones from your backup, instead set up as a new device.

No audio (line-out) for some QT and all Real Player

This is strange.
This link, which uses Quicktime, will only play SOUND via my internal speakers: http://www.umeportal.com/player.aspx?fid=393&ftyp=3&pgid=7&hid=13728&fp=qt
While this link will play SOUND via external speakers: http://www.apple.com/getamac/
Same with all the HD trailers: http://www.apple.com/trailers/ The the SOUND plays externally ok.
Here's another one that will ONLY play from internal speakers: http://www6.islandrecords.com/site/promo/quicktime/killersbonesquicktime.html
Real player, will play SOME mov files externally, but most others mp3, mpg, mov, will ONLY play via internal speakers.
Ok, what gives?

Ugh....nevermind.
I removed USB Overdrive and external audio started working for everything.
This is strange becaues I have been using USB overdrive for about a week w/out any issues.
At the time I noticed the problem...I had been using QT to convert mov files to h.264, mpeg4, Sorensen 3 files and for some reason, using the QT export features -- with USB Overdrive installed -- mucked up audio play back. Go figure.

Garage Band Claims Audio Files Are In 8-Bit Format And Unusable.

I've used garageband to make my podcasts for about a year now, with no problems.
Sometime in March, though, there were two changes to my setup and I started noticing big problems.
The first change was the upgrade to 6.0.5 of garageband, which happened in early march. The second was that my harddrive was full, so i started saving my garageband files to an external hard drive.
The issue I'm experiencing is that when I load up a saved GB files (from the External HD), it will give weird errors, like, "The File Type Is Not Supported," and "One Or Multiple Audio Files Changed In Length," and "Garageband found 1 audio file in 8-bit format - the file is unsupported and cannot be played back."
When the error messages stop appearing, large segments of my podcast are missing, or the segments will be blank with no audio.
Generally, if I get my entire podcast done in one go without saving/reloading it, this is not a problem.
I've lost hours of work with this bug.
Can anyone suggest a solution?
Thanks.

Parse lines out of a StringBuffer and/or InputStream

I am loading and parsing a ~40MB text file. I am retrieving this file using the JCraft JSch SFTP library. This has given me no problems so far.
Since I need to process this file line by line, my first approach was to read a character at a time off the InputStream provided by the SFTP library, collect characters until a new line was reached, then parse the line. This proved to be extremely slow. Now I'm pulling 1024 characters at a time into a byte[] from the stream and pushing that array into a StringBuffer until the end of the stream has been reached. It has sped up considerably, but now I don't know what the best way would be to process the buffer.
What would be the best way to split off and process every line of this file? It seems redundant to pull the whole thing into a string buffer then parse it again by using charAt() and substring() to find and chop off lines. Reading character by character from the stream works in theory but is much too slow. Trying to parse the byte[] with fragments of lines is impractical and error prone.
Memory is not an issue since it is running on a dedicated batch server, but speed is important.
Thank you.

Front and Rear Audio Through only one Socket - Sound Blaster Live! 24

<p class="MsoNormal">PLEASE HELP ?
<p class="MsoNormal">I'm getting Front and Rear Audio through the front speakers (Front Socket), and nothing out of the back.
All cables are set up correctly; I have reinstalled drivers, updated drivers etc. and the software.
What?s going on ? :S

I'll answer you here, as I believe it may be helpful to other users as well... You will need to download the latest drivers for Li've! 24-bit under Vista, which are available [url="http://us.creative.com/support/downloads/download.asp?MainCategory=&nRegionFK=&nCountryFK=& nLanguageFK=&sOSName=Windows+Vista+32-bit&region=&Product_Name=Li've%2+24-bit&Product_ID=035&modelnumber=&driverlang=033&OS= 26&drivertype=0&x=29&y=0">here[/url]. These add AudioConsole, which allows you to select CMSS options for your soundcard.

On Windows XP this was never the case, for surround sound I would leave it in Dolby mode.
This is indeed strange... In ProLogic mode, as I already said, it'sproduces?surround sound from the 2 front channels but this is not the same as discrete sound, which is eventually 6-channel analog or Dolby Digital. It really all depends on the content you are playing. Also note, that a lot of the Dolby movies available on the web, may use AC-3 format, but may still be stereo only. On this content ProLogig will produce nice surround sound. (Media Player Classic states clearly how many channels are actually available)?If you however playback a true 6-channel AC-3 movie and you have ProLogic enabled, you will most probably not hear any dialogue, or just its echoe... (Assuming that you leave the AC-3 decoding to happen on the soundcard, which will then send the signal through the 6 analog channels)?How is your soundcard connected to the receiver? SPDIF/Optical or only analog??

Line out audio line level too low to be useable, just started after update

I'm pretty sure this is a software issue. My line out level is so low it is not useable. Headphone jack still works. I removed all the audio preferences, cleared the cache, rebooted, reconfigured audio midi setup. I maxed out the volume, used the sound preference pane and selected line out. No improvent.
I picked up an m-audio Fast Track for now. Has anyone experienced this and resolevod it. I'm running 10.5.8...
< Edited by Host >

I put my son's PPC Mac Mini in target disk mode and booted off of it. Audio issue still persists. I wonder if the digital out / line out switch has a non volitile register ? or it could be fried ? I booted linux on onthe box and used alsamixer
I saw the ES9168 (or something like that).. that's the switch right ? It had no value.
I guess for now I'll get an Maudio device for sound.. but I still hope to figure our what if this is a software issue or is it hardware. The signal is low.. I put my oscilloscope on across the speaker inputs while a sound was playing.. 25mv! It's supposed to be 1v. I don't know how they designed the line out, there is no schemetic. I wonder if what happened is the line out pre-amp blew and I am hearing whatever signal is leaking/bridging across.
Everything else on my late 2005 powermac g5 is fine. It may be 5 years old but I can render HD video fine, and it's been very stable so I figured I'll keep it till it dies. There's one problem with that though. I've got over 3000 pictures in iPhoto that I shot, and my perl/php development projects are on it, plus my family videos are all on it I server them up to the Apple tv. Ahh.. I guess I have to backup / archive to something that will be compatible.
Well.. I'll start saving.
If you can think of any other possibilities let me know. I kind of think booting off the imac in target disk mode ruled out software, but then again the audio driver may be different from the one my G5 uses. Is there any Apple Service Disk kicking around for a Powermac G5 late 2005 model ? Maybe there's code on there to test / initialize the onboard audio.

Interal speaker vs line out for boot chime

On my G5 tower, the boot chime would play through the line out connection. On the Intel tower, the boot chime plays through the internal speaker and everything else goes through line out. is this a "feature" of the intel tower, or is there a setting I missed somewhere?
Trivial, but annoying for sure.

It's a feature. The tone indicates that the hardware has passed the power-on tests. They didn't want that indication lost when something was plugged into the audio output jacks. There is software available to shut off the startup tone. Look on Versiontracker or Macupdate. Not all the applications work on all Macs.
