Mac Pro :: USB Audio Output Level For Ext. Headphone Amp?
Jan 17, 2009
I've got a Headroom Headphone Total Bithead mobile Amp., 2.66 MacPro, and Sennheiser HD650's (that are hard to drive). The amp. has a high and low gain switch. The low gain sounds better, but I can't get enough vol. when on low gain. I've got iTunes level up as high as it can go. I've played around with Sound prefs. and the Audio/Midi sound levels. They all seem to actually be the same vol. control.
I also see that iTunes, under "Get Info" has an individual vol. adjustment, but I'm not sure if I really want the sound files to be pumped up for when I use them on my iPhone.

I was using my 13" White Macbook (Spring 07) all day today, listening to music on headphones while working. I brought my computer over to a friend's house and attempting to line out some audio from Garage Band to speakers through the headphone jack and suddenly all audio began to have skips & spaces every second or so. I can still the hear songs but they are constantly interrupted. I tried Itunes & audio from the internet, and two different pairs of headphones I know work. Same problem every time. The strange thing is that the audio works perfectly out of the internal speakers. Has anyone had this same problem? I haven't seen anything on the web that was similar. I tried the Q-Tip/Toothpick trick suggested on a bunch of other threads. But I don't think it's an issue of the computer not adjusting to the headphone setting. Also tried to resetting the battery, but that didn't work either.

i have an intel macbook running leopard with the most recent update. A problem arose a day before the update was installed wherein my macbook no longer transmits sound through the headphone jack. i have no reason to suspect a hardware failure, there has been no damage to the computer. is there any way this could (please, god) be a software failure? and if so, one that i can fix?

I feel like I once had a PrefPane for this problem but just am having a hard time searching for it. Currently I have my heaphones jack Line-In routed to my AV Receiver for iTunes music in my room, but whenever I am YouTubing or other stuff while listening to music the System Sounds come out of my Loudspeakers too. I am interested in routing only the iTunes audio through the headphone jack, and everything else to run through my iMac's internal speakers (2007 iMac AL).I saw the SoundFlower thing out there but didn't think that was the ticket

I normally have my MBP on full (or mostly full) volume, but when I plug in headphones, I drop it down to the absolute lowest (or one up from that) level. Anything higher than that is deafening with my headphones. Normally my MBP automatically dropped it down to about that level whenever I plugged in headphones, but recently its only been dropping it down to the halfway point. This causes momentary deafness as I hit play on my iTunes, forgetting its only halfway down, and additional deafness from the clicking as I frantically hit Fn-F4 to lower the volume. Is there a way I can set the default level that OS X drops the volume to when I plug in my headphones?

For some reason, I can't get Logic Express 8 to output audio to my Mac's attached speakers. It outputs fine through my M-Audio interface, though, but I'd just like to listen without headphones.

I went to this thread to solve my low volume issue..[URL]
The problem now is my headphone jack does not work. I have my MBP closed with externals plugged and only to have the internal speakers working.

My internal speakers work fine. When I plug in headphones, the left side has normal audio for about one second, then becomes barely audible. The right side is barely audible all the time. If I unplug them, and re-plug them, the same exact thing happens. Everything looks good in the sound properties page. I know the headphones work because I tried them in another device.

I have this question about the MBA: on my MBP, the headphone jack allows me to use my iPhone headphones when skyping, i.e. it has input as well as output functionality. Does the MBA have the same feature?

I have a 13" 2010 MBP. When my headphones are plugged into the jack, and no sound is being outputted, the headphone jack seems to "turn off". If I want to do something that outputs a sound, like emptying the trash, there is a 3 second delay from when the trash is emptied to when the sound is played.

I have my Xbox 360 sound out-putting through an optical digital cable to the digital input of my Dual 2.3ghz Power G5. My mac recognizes the signal but I was hoping I could somehow use the incoming sound to output through my headphone speaker jack on the front of my mac. Both my mac and xbox 360 use the same monitor.
I noticed it doesn't work that way. Is there a way to switch the incoming digital signal to route through my headphone port on the front of my mac? There has to be a way.
Information:
Powermac G5 Dual 2.3 Mhz
Mac OS X (10.4.10)

Is it possible to have the Mac Pro output signals from the optical and the headphone port on the front of the case? I like to have my speakers going as well as have one cup on my ear when listening. Surely there must be an application out there that forces OSX to do this.

I have a major problem with FCP 10. I cannot for the life of me figure out how to do a simple audio level adjustment using the keyframe editor. I have a audio-video clip that is using dual channel mono audio. I have a shotgun mic on one channel and a handheld mic on the other.
I've gotten as far as getting both incoming channels to playback on both outgoing channels. What I need to do is to shut off one channel or the other, periodically, in order to preserve the quality of the audio. FCP won't let me use keyframes and the range editor wasn't work either. It should be simple but it seems that it isn't. What do I have to do to cause FCP to do this very simple operation?

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 built in speakers work fine all the time, even when I have headphones plugged in. I looked under the output devices in the system settings and the only option is for built in audio output, a.k.a speakers, there is no option for an alternate audio output, a.k.a headphones. When I plug in my headphones nothing happens, sound continues out of the internal speakers like nothing happened.I have Mac OS X version 10.4.11.. iMac7,1.. 2 Ghz Intel Core 2 Duo 1b 667 mgz DDR2 SDRAM

This headphone/headset that is equipped with a mic does not work properly when I connect it to the audio input opening. The headphone/headset is only equipped with one plug (is this the proper term?).
When I adjust the audio setting (apple icon--> System Preferences --> Sound --> select "Input" tab --> highlight " Line in; Audio line-in port") I can only hear sounds through the headphone but the mic portion does not pic up. If I hit the mic portion I see the bars move, that would indicate some sound being picked up. However, when I try to use the mic, through Mac Office Powerpoint 2010, the sound (if received through the mic) does not pick up.
Why is this happening? Do I need some extra external component for the microphone part of the headset to work or do something extra in the System Preference area?

MacBook, Mac OS X (10.6.8)

I recently got my MBP and I noticed there's a issue with headphone audio distortion. When I plug in my earphone or headphone without any sound playing, there's a clear whining noise like zi zi zi sound which is really clear, sounds like old 80s radio noise. When I play the music, of course it was covered by the sound of music but it really bugs me out knowing that I cannot listen the pure sound of my music. The volume of this distortion noise would not change while I turn up or down the volume of my MBP. I asked someone professional, he said it's a famous issue of screen frequency disturbing audio in macbook pro.

The audio on my macbook suddenly stopped working. When I click on the audio adjuster, it won't even let me change the level (the little circle is white now, not blue).
But when I plug in headphones or an external speaker, everything works fine. I can once again adjust the audio and get sound
There was a red light eminating from the audio out jack for a while (last couple of days) but today, there is no longer a red light. Still no audio from the speakers.

Basically I dropped my macbook pro and ever since I have not been able to get any noise out of the speakers or the headphone jack and there's a constant red light in the headphone jack (I have tried the toothpick method).

I was listening to my headphones through my new MacBook Pro this afternoon and an electronic noise started coming through. I am using an external monitor with my computer closed, this sound decreases when I put my hand on top of the closed laptop.

I just bought the brand new macbook pro 13" lowest grade and do a lot of simple recording. My old macbook had both an audio in and out. one labeled headphones and one with the two triangles pointing toward the circle. It was expressed to me that this new one jack could support audio out and in as labeled by apples tech specs. I tried hooking up my synthesiser to the port yet garageband did not recognize an audio in port, nor did the computer.

I want to connect speakers and a headphone to my Imac at the same time.Since there is only one audio output in the imac, I need a audio splitter and I think I need a headphone splitter then?Now the problem is there is no volume control on my headphone and I want it at a different volume then my speakers, otherwise when I turn my speakers on and the headphones are still connected and I turn volume up loud it will ruin my headphone ( and I don't want my software volume almost down and my speaker control way up)Now I found this headphone splitter, but my question is, will the sound quality still be the same because I need the same sound quality.
I know it's a difficult story,

My Early 2009 aluminum macbook does not recognize headphones. when i plug in, noise continues to play through the speakers. When I sleep and wake it, the headphones are recognized. I am not sure about the other way around, but this is getting to be supremely annoying.
