More finegrained audio volume control? (Harman/Kardon USB SoundSticks)

Hi,
I've been asking this question for every major release since 10.2 and I am near to just give up on it. I use the Harman/Kardon SoundSticks (the older USB model, not version 2 with the regular audio jack) and since 10.2 they are simply too loud. Since the speakers themselves do not have any volume control knob it has to be a software solution.
With OS X's sound volume keys I can only use "1 bar of volume" when in front of my Mac and even that is too loud. The only solution is to turn it off completely or to lower it a little bit via the volume control slider in the menu bar. This results in approximately "3/4 bar of volume". Moving it just a tiny bit down from here results in muted audio.
Is there any way to just reduce the overall audio volume via software? Sure, I can do it app by app, but I really need a systemwide solution!
Thanks
Björn

Then maybe you're really lucky or just like the high volume setting. This problem exists for years now and it's definitely not caused by my hardware/software. It was the same with the following Macs:
- Power Mac G4
- iBook G3
- iBook G4
- Power Mac G4 Cube
- PowerBook G4 Ti
- PowerBook G4 Alu
- MacBook Pro CD
- MacBook Pro C2D
And it happened on all releases of OS X from 10.2 up to 10.5. All versions were installed clean without upgrading so I really have reason to believe it's Apple's sound driver for the SoundSticks...

Harman Kardon USB Soundsticks (1st Gen) Screeching/Static

After upgrading to 10.6/10.6.1, I now get periodic, short screeches/static on my USB Harman Kardon Soundsticks (the USB-only version), regardless of the source of sound. So playing music is definitely now intolerable.
Anyone else experiencing USB sound related issues?
This is the last straw for me in using USB-based speakers as I've they always "disconnected" and were no longer accessible when performing large file transfers with USB drives. Only a restart would make them accessible again. With this new issue in Snow Leopard, I'm ditching them for mini-plug based speakers.

Don't give up +so fast+. I'm trying to find a way to lower the USB SoundSticks' volume for years now without luck. But other than that, they still work fine with 10.6.1 over here!
I know of the static noise problem, but I only had that years ago with 10.3 and/or 10.4 and it was caused by my USB hub. Connecting them directly to my Mac worked fine and since using the following setup I never had a problem:
MacBook Pro (had several models and PowerBooks before) - Cinema Display - Belkin USB hub - SoundSticks
Yes, there's 2 hubs involved and it works fine. I use the somewhat older 30" Cinema Display and this Belkin hub: http://catalog.belkin.com/IWCatProductPage.process?Product_Id=158910

HT2490 my audio volume control defaults to mute whenever I start the computer. Preference settings have no effect. Technical support couldn't help.

Audio preference settings continually default to minimum with Mute ticked whenever I start up.
Technical support could not help desite 30 minutes or more of trying various approaches.
The technician "proved" that it is a system issue and not an individual "user" setting that is affecting the computer.
Any ideas about what is causing the problem and how it might be fixed?

Thanks for the inquiry and feed-back. Tech support advised me to unlock the preference dialog box when I was logged in as the administrator. We changed the volume setting to mid-way on the scale and rebooted but the volume preferences reset to minimum volume with Mute ticked. He also had me try what I assume is a reset of defaults on boot-up. I held the Command/Option/P keys and operated the power on switch, then immediately held down the R key which put the computer through a different start up sequence. Once again the volume was muted and indicated minimum when I checked. No luck either when we created a New User account and set the volume control to mid-way as previously mentioned. Other approaches he suggested were too involved for me to accurately relate but involved deletion of some files associated with the sound system. No joy which is why I have sought other advice. Thanks anyway for your interest!

Background Audio Volume Control

Hi everyone!
Thanks so much for your help on my background audio question.
I was wondering if someone could tell me how I can control the
level of the background audio that i'm using from the
Project>Preferences>Background Audio Tab? I would prefer the
level of background audio to be less than what captivate thinks it
should when I'm talking through ny intro slides.
Thanks again for your help and I'm gald to be aboard the
forum.
fajitaman

Hi fajitaman
Try this. Click either Project > Preferences... (if you
are using Captivate 2) or Movie > Preferences... (if you are
using Captivate 1). Then click the Background Audio tab. Once you
do this, you should see a button labeled Edit... Click the Edit...
button. (If you are prompted whether you are certain you want to
make changes, click the Yes button.) Click the Adjust volume button
and adjust the volume level as desired.
Note you also have an additional option. One I'm personally
not fond of, but it exists. That is the option to "Lower background
audio volume on slides with additional audio". If you use this
option (I believe it's enabled by default) you hear a definite (and
noticeable) volume reduction when slides containing slide level
audio are played.
Hopefully this helps... Rick

Audio volume control in quick start bar not working after last HP update

Volume keys at top work fine but clicking cursor on quick start icon for volume control does nothing now.

Hi ,
Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP ENVY 17 Notebook and issues with the Audio after Windows 10 update. Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system that might need updating. Restart the Notebook after updates have been done. If your computer is having problems finding and installing operating system updates, try using the Windows Update Troubleshooting tool to fix the problem. Here is a document that shows how to update drivers that are not working correctly with Windows 10. I hope this helps you. Thanks.

thanks!Huh. Interesting problem. You'd actually want to be increasing the volume on the individual samples in the stream, rather than some control on the player itself.
I'm presuming you can't just turn up the volume on the other end?

Is a sudden blue screen log out connected to audio volume control?

I use three computers all with the appropriately updated Mac OS (10.4.5). In all three, I am experiencing the same curious problem. Now and again, the screen goes blue and then we are into the log in routine. All applications have to be restarted. I have noticed that adjusting sound by making use of the keyboard sound control appears to lead to this event happening (after several seconds delay). There is an additional common feature to all of this: I have replaced the hard disk in all three. In this Powerbook 12", I installed a 250 GB disk, in a 20" G5 iMac at work, I replaced a 150GB disk with a 500 GB and then used the replaced 150 GB disk to replace an 80 GB disk in an 18" iMac at home with a 1.6 GHz processor.

Two things: First, 10.4.5 is not the most updated version of Tiger; it has been up to 10.4.11 for some time now. You should run your software update.
Second, this forum is for problems running OS 10.5 Leopard, not 10.4 Tiger. You might have a better chance at a good response in the Tiger forums here:

Harman Kardon USB Speakers OS 10.8

I followed the earlier discussions, and advice, to get the speakers working. Then got (I think) 10.8.2 or 3 and they started working !
When 10.8.4 came they stopped again!!
What is going on?
HELP!

usb speakers are not speakers reallyi they are an usa soundcard and such devices needs drivers and if drivers does not work with the os then they don't play contact the producer for drivers

Lenovo Miix 2 8" - Separating volume controls for headphones and speakers

The sound options for the Miix 2 out the box combine the volume control for internal speakers and for headphone jack, i.e. there is only one volume control for both the speakers and the headphones on the mixer settings at the the volume icon at the lower right hand of the desktop. So when headphones are plugged in, there is still only a "speakers" control shown.
I work in an office and would like to have the speakers muted if the headphones are pulled out.
Similar issues resolved on other devices directed to install an alternate sound driver (that offered separate controls) or pointed to some other settings in the sound driver properties menus where this could be manually done, but I'm having trouble applying any of them to this device.

Worked beautifully! Thank you very much!!

Tried it reverting to an older version of Skype. Didn't work.
But! I believe I may have found the solution.
Here are the steps I took to solve the issue:
1. Right click on the audio volume control icon -> Playback devices. The Sound window and Playback tab should be open.
2. Set Speakers/HP as both the Default Device and the Default Communications Device.
3. Go to Skype>Tools>Audio Settings. Set Speakers settings to: Speakers/HP (IDT High Audio Definition CODEC).
Hopefully this will work for anyone else who has the same or a similar problem.

Is there a volume control specific for Facetime?

I'm wondering if there is a way to control the volume of Facetime without using the main volume control (like how you can control the volume of Skype within the application itself). Some kind of separate application or tweek?
Thank you.

No, there is no audio volume control specifically designed for the Facetime application. I'm using Snow Leopard 10.6.8 here but I'm sure this info also applies to your osx. You'll find that Facetime is not nearly as sophisticated as skype, at this point in time.

Volume control device wont come on plz help me

i have a problem BIG problem with my volume control. i cant get the green light to light up on the volume control for some reason. the subwoofer itself still works cuz i took it apart and hooked it up to another speaker system that i have and it worked perfectly. i think it might have to do with the board inside with the subwoofer. i tried to wiggle the wires a bit to see if there was a shortage but that didnt seem to be it. its not the fuse either cuz i replaced it and nothing still happened. i dont really know so if someone would help me out i would really apprieciate it.
Message Edited by KA-Pow on 04-01-2005 08:47 PM

KA-Pow,
No green lights on volume control means no power. My guess would be either the volume control or the power adaptor that's probably faulty since you have mention testing the subwoofer and it's fine. I would think it's more on the volume control. You're best off contacting support to have it repair.

Volume control with USB Audio device

Hello all.
I have just purchased a cheap USB audio device to connect my HiFi to my laptop with only one, neat USB lead and a USB hub - meaning I no longer need several USB wires and an audio cable across my desk.
This works fine, but I have just noticed that the volume control in OS X has no effect on the output now, only Mute or On. The volume within iTunes works fine, but not the OS X one.
Any way I can avoid having to use the volume on the hifi when using the USB Audio device?
Many thanks.

Don't think so unless that piece of hardware came with compatible Mac software to control it.

Mapping Alsa Volume Control for USB SoundCard (C-Media 650)

Hello everyone who is interested in helping me solve my volume control problem!
Lets see, I have sound playback working, currently I am listening to some Foo Fighters mp3s in XMMS using the Alsa plugin, so I can't complain too much.
However, volume control doesn't work. If I set the alsa plugin to use software volume control, then I have volume control but its not ideal and it doesn't help me when I'm not using xmms. When I run alsamixer or open the gnome volume control, I have multiple volume controls for the "Speaker" device. The 1st pair of volume controls do nothing, I can mute them and my music keeps playing... no idea what they're controlling. The 2nd pair ("Speaker 1") DOES control the sound volume. I just need to find a way to remap it or something so I can configure my applications/tray icon/etc to use it. (And preferabbly not the other 6 channels)
In the Gnome sound control, the devices are:
"Speaker" - stereo control that doesn't do anything
and "Speaker 1" - a 7.1 channel (8 sliders) with the first two controlling front left and right sound for my stereo speakers.
I've tried setting xmms to use "speaker 1", but the option is not in the drop-box, tried typing it manually but that didnt work.
I set my tray icon to control "speaker 1" but the sliders don't seem to lock properly and the volume just jumps around, unlocking the channels and not staying balanced or scaling with the slider.
The only way to get the volume to change as expected is to open the gnome volume manager, make sure the channels of "Speaker 1" are UNLOCKED and slide the first 2 sliders to the desired volume.
So I was thinking if I could just remap the first two channels of "speaker 1" to something else using an alias or link or editing asound.state (which just confused me) for example, then I could use my alias to control the sound in my applications. Thanks for any help with this!

Thanks again!

Some other observations that may be helpful (and, hopefully, get closer to the heart of the problem)...
(1) Whenever VLC is playing audio (as mentioned in previous post, it is only application that works in desired manner), it will show up in Kmix's "Playback Streams" tab. Whenever Wine and Firefox are playing, they do NOT show up in the "Playback Streams" tab.
(2) Kmix will not allow more than one open application to grab the UA-5 sound (e.g. If I open Firefox and play audio, stop playing audio (while leaving Firefox open), then open VLC and try to play audio, VLC will not play audio (unless Firefox is closed)). This is likely a related problem to the problem outlined in the previous post, but it might not be. If it isn't, I'll take advice on how to let KMIX grab multiple audio sources simultaneously on the same sound card.
Thanks for reading!

Volume control when using front row with an external audio interface

Hi,
I got my macbook last week, and so far, I love it. But I've got a small gripe with FrontRow - in my room at college, I have my macbook plugged into an oldish Tascam US-122, which I use a lot for recording. The Tascam is connected to my expensive active speakers, and ideally, I'd like to be able to play back via FrontRow to the Tascam, to the speakers, while retaining remote control. This isn't a problem for selecting Photos/Videos/Music etc, but the problem arises when I want to change the volume - the remote simply controls the volume of the macbook's internal speakers, not affecting the output of the Tascam.
I know I could just connect the speakers via the headphone output, but that would mean more cables, and more chopping and changing system preferences to suit whether I'm making music or just listening.
*So - is there any way at all that I can make the macbook's global volume control (using the volume hotkeys and remote) affect the signal its sending (via USB) to the Tascam?* I know its not impossible, because until recently I used it with a PC running XP, and that allowed me to use the volume control app to boost or cut the Tascam's volume. Perhaps its an issue with the Tascam's OSX driver?
The Tascam has its own physical volume knob, so its not like I'm stuck listening at deafening or very quiet volumes, and I know this sounds like an issue with my laziness rather than FrontRow or the macbook, but surely it defeats the point of FrontRow if I have to walk across the room every time I want to turn the tunes up or down?!
Any help would be much appreciated!
Cheers,
Thom Bishop

hmm, yeah, thats kinda what i suspected - i reckon this is to do with the way the frontrow interface is set up, but theres no way (as far as i can see) to make everything pass through the main system stereo channel BEFORE going to an external audio interface... which is COMPLETELY bizarre, since system sounds/alerts get passed to the audio interface fine.
and no, i very much doubt whether ANY external audio interface would respond to apple remote (gap in the market, perhaps?).
this would be a fairly simple problem to solve, if only apple were aware of it... of course, i COULD try getting to grips with audio units and seeing if i couldnt fix it myself, but ive frankly not got the time to learn how that works! how can i make apple aware of this issue?? are they already aware??
