Bypass master volume for constant white noise play (KDE)

Is there a way to play sound while ignoring the master volume control, even bypassing mute?
I have tinnitus (ringing in the ears) and I get relief of these symptoms by playing white noise 24/7, I currently am using http://playnoise.com/ but there are many different sources of white noise, it could even be an mp3. I like it to be playing at the same volume, all the time, no exceptions. But, when I turn the volume up and down via my media keys or system tray, for a song playing in Amarok or a video playing in YouTube the white noise is also turned up and down, this is not needed or desired.
What I'm trying to do goes against the definition of what a master volume is, but I figure it's worth a shot to ask.
The next option would be to have volume adjusters for applications which I have seen done before. 90% of the time I'm adjusting web browser volume.
(I have medium-ish experience with Arch)
Thanks

tricky, but you could achieve that with alsa's softvol plugin.
first you need to have alsa-plugins installed
then add something like this in your ~/.asoundrc
pcm.!default {
type plug
slave.pcm "softvol"
ctl.mixer0 {
type hw
card 0
pcm.softvol {
type softvol
slave.pcm "hw:0,0"
control {
name "Master2"
card 0
this should create software volume control called 'Master2' and make applications use it as default (you need to restart all audio applications and sound servers until it takes effect.)
now you should be able to play white noise from mp3 and set the 'real' master channel for it's output, while all other applications are controllable via Master2. Ideally you should set your card's real master volume to 0db
only issue with this that your white noise will be played full blast unless the application from where you're playing it from has its own software volume control. You can solve this by adding another softvol device in your .alsarc (simply copy the pcm.softvol part and change the control name from Master2 to something else) and use it as output and volume control for the noise.

Alsa/pulseaudio - keep the same master volume for speaker&headphones

Hello,
I have laptop Asus N550JV.
I installed alsa ant pulseaudio (alsa-utils and pulseaudio, nothing else, no pulseaudio-alsa plugin, because I noticed that it causes me more problems rather than reduces them.
the problem is that I want to keep Master audio channel untouched. If I listen through speaker, I could set master volume to 50%, then I can plug in headphones, set volume to 100%, then I can unplug headphones, the sound will play still at 100% THROUGH SPEAKER for about 0.5 sec. and after 0.5sec it will set back to 50% as I set when I was listening through speakers.
My question is, how can I fix this problem. I see that there are 2 ways to fix this:
1. make a lag time (delay) to switch from headphones to speakers.
2. keep the same master audio volume for both headphones and speakers.
Any ideas? I think the second solution would be easier to make, but I dunno how

Hi,
I am having the same problem with the ringer volume automatically being reset to some other volume. In my case the ringer volume slider under "Settings" + "Sounds" seems to be tied to the iPod speaker volume.
For example, I go in to "Settings" + "Sounds" and I set the ringer volume to maximum, I return to the home screen and then back to settings to make sure the volume is still the same (and it is), and then I go to iPod and play a track via the built-in speakers (i.e., no headphones). If I happen to change the iPod speaker volume and then stop playback and return to "Settings" + "Sounds" from the home screen I find that the ringer volume has been reset to whatever volume level I had previously set the iPod speaker volume.
I had assumed that these two volume settings were independent . Certainly, changing the ringer volume does NOT affect the iPod speaker volume, but setting the iPod speaker volume DOES affect the ringer volume.
Hopefully this is corrected in the first firmware update.
I have an iPhone 3G.

IPod Video 5G 80 gig - White noise

I have an iPod Video 80 gig and I notice that their is always a background white noise (hiss). I start a music and press pause for this test.
When I close the volume I can hear a clip when the volume is close. As soon I increase the volume I hear a white noise (hiss) and it keep the same level until I get to the 3/4 of the volume then it's start to make the white noise louder and also I can here some clipping that is comming from the wheel until I get to max volume.
Clicker sound : OFF
EQ : OFF
Sound Check : OFF
The problem I got with this white noise is when I listen to calm music I always here the white noise (hiss) like I am listen to a tape cassette.
I was hearing this with my Sony MDR-EX70 but I just purchase the Ultimate Ears Super.Fi 5 Pro (white) and these headphone are so clear compared to my Sony that now I hear the white noise even more !
So I would like to know if this a poor SN ratio noise of the iPod built-in amplification or it is just my iPod and my friend iPod too ?
It would be interesting if a couple of people could try the test and see if they got the same background white noise.
- Start a music
- Pause
- Close the volume (should hear a click a the close position)
- Increase volume (should start to hear the white noise (hiss)
- Increase the volume to max and at about the 3/4 of the volume up to the max volume you should hear some clipping noise from the wheel sensors and the white noise should also increase in level up to the max volume.
If all iPod are doing this then Apple should redesign the amplification to increase the Signal to noise ratio better than what it is right now.
I would like to have some feedback on this from the people who gonna make this test.
Thanks

Also when I plug it in my stereo system I can hear the clip when I close the volume.
The white noise is their also but I cannot hear it at the listening distance from my speaker. But if i'm right whe you plug the iPod on the dock we are not using the internal amplifier of the iPod but just the output signal.
I have a Class A amplifier in the living room so to ear some white noise from the speaker I need to bring my ear 2 inches away from the tweeter.
On the iPod the amplifier could be a Class D with alot of white noise.

N95 Java app master volume

Is there a setting do control the master volume for Java apps in N95?
I was trying to play some Java games but the sound is too loud when starting up so I would like to adjust the volume before the Java game is loaded.

Severe random white noise problem...who to contact?

i primarily use logic with the vienna symphonic library software and generally things have been great...however.
occasionally when selecting notes in the piano roll severe blasts of maximum volume usually painful white noise will shoot out of the speakers.
this is quite unsettling for many reasons.
i've noticed some threads around the web about this (for example http://discussions.apple.com/thread.jspa?threadID=2144002&tstart=30 ) and i would like to do whatever i can to help apple fix this.
for me it's pretty specific as it has only happens when editing in the piano roll in a track that has a vsl instrument loaded into it and i click and drag to select multiple midi notes. perhaps it's a vsl issue but the thread i mentioned above suggests there's an apple issue. i'll post this on the vsl forum too.
what's more disturbing is it's happening more frequently but i haven't changed anything in my setup that seems remotely related to this except upgrade to 10.6.3 today which didn't help.
i'm using logic 8.02, snow leopard 10.6.3 on a macpro 2.66 quadcore with 8bg of ram.
so if anyone has any insight on how to fix this it would be wonderful or if someone knows of an address i can send my circumstance to that may help apple fix it that would be great too.

White Noise / Popping Problems

Hi,
This question is more about microphone equipment than GB2.
I have a Sure SM58 microphone -- am going to be recording an audiobook. I need to get some sort of pop screen (to help keep the "P's" fromm sounding so puffy) ... do I need to buy a proper "pop screen" or can I just get one of those wind screens that cover the mic head (cheaper) ?
Also, my G5 makes quite a bit of noise -- I think part of it is contributing to the background "white noise" of my recordings ... I have read that a windscreen sometimes help.
Should I get both a windscreen and a pop screen? And: any other suggestions on how to reduce the "white noise" (without building a seperate room for my mics)?
Thanks,
Damon

I couldn't underscore enough how important a defuser (pop screen) is. If money is tight, a very cheap thing to try is pulling a pair of pantyhose or stockings over a coathanger.
As for the white noise, a wind screen isn't likely to help (if it did, it would be cutting off all the high frequencies of everything).
The first thing to try is to get the mic as far away from the machine as possible, keep the gain on the mic as low as you can, and stay close to the mic (again the defuser is rather important for this)
One other thing you might try is looking in your Energy Saver preferences and try setting the speed of your processor to "reduced", this may bring the fan noises down quite a bit, and once you've recorded your part you can reset the preference to Highest or Automatic)
Hope that helps --HangTime [Will Compute for Food] B-)>

HOW TO TURN OFF NAP TO ELIMINATE WHITE NOISE?

RE: HOW TO TURN OFF NAP TO ELIMINATE WHITE NOISE
Ive discovered that when ever I attempt to record audio in Logic pro 8 I get a constant white noise in the back ground. I've seen proevious posts regarding this and have downloaded the xcode developer tools but cant find the right path to locate the "nap disbale" option. I'm using a mac pro intel 10.6.8 [snow leopard] please advice as I am going out of my mind!!...thanks

There is a forum devoted to Logic Pro you might want to ask there.

How do I level the volume in a piece of music without creating white noise during silent/quiet parts

It's actually the original Star Wars trilogy soundtrack. The volume swings by 25 db or more, even during the same track. You can't listen to it without riding the volume knob. That's not hyperbole, you actually cannot hear parts of it if the loud parts are at a safe volume. It's not a bootleg copy or anything; I bought the CD's. Pathetic that they haven't already done what I'm trying to do, if you ask me.
Raising the volume of my sterio doesn't create white noise, so it seems like I should be able to duplicate the effect somehow, probably with some kind of dynamics processing. Classic Soft Knee, for example, has the white noise problem. When I used it in the talk radio business, it would also amplify the speaker's breaths. I've fiddled with it and tried to come up with my own settings without success. Maybe I need a different tool entirely?
I'm doing this for my son. He's 5 and loves Star Wars and loves listening to the music in the car wherever we go. Thank you for any help you can give!

My first, only slightly tongue-in-cheek reaction is to say, well done to the manufacturers of the CD!! To actually allow the "full" dynamic range of the original to be released on CD!!
Sorry, I know that is not what you wanted to hear, but it is such a pleasant change that I couldn't resist commenting on the fact that the CD manufacturer actually does NOT want to "homogenise" the dynamic levels. However, I realise this does create a problem for you in the circumstances of wishing to play the CD in your car.
You are correct, IMO, to be looking at the use of compression to reduce that dynamic range, though your talk of "white noise" is concerning. Certainly the effect of compression is to reduce the dynamic range by, as it were, "decreasing the level of the loudest and increasing the level of the quietest parts"; there is a danger that increasing those quietest parts COULD increase the "noise" but I suspect the CD was recorded in pretty near "ideal" conditions, i.e. the noise floor was so far below the quietest signal that raising the level of that signal will minimally increase "noise", if at all.

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise.

I have some dts cd's that I want to import into itunes on a windows pc and then play back on my apple tv 3 (i think its 3, about 9 months old) to listen to through my onkyo amp via hdmi as dts, when I play back I just get white noise. I have seen lots of old posts which go on about converting files but am wondering wherher at the current time with the latest versions of itunes and apple tv whether this should by now be a virtual play out of the box solution.
I have tried connecting my atv to the amp by optical cable but that didnt produce anything better and am assuming that a hdmi cable should be able to reproduce everything an optical cable does.
Is this something I should be able to achieve without having to recode the files?
Tracks are imported to itunes as apple lossless, have tried setting the atv audio settings to auto and 16 bit, neither works yet I was told some time ago by an apple rep that the atv shoud be able to handle any type of audio as it just passes it to the amp to decode. I am not stupid but not that technical when it comes to audio and bitrates etc so any explaination would be appreciated.
Thanks in advance for any help

Willy, the procdedure you describe works perfectly for AppleTV G1. In fact, I frequently play DTS music discs ripped to my iTunes library as Apple Lossless (ALAC) and synched to the ATV. What happens is that, as far as iTunes and the ATV are concerned, a conventional stereo 16/44 audio file is being played; however my reciever detects the DTS data stream, and instead of outputting static, it decodes the 5.1 channels correctly. This process parallels the way DTS discs were designed to be played back: a conventional CD player is connceted, via digital out, to a DTS-aware reciever/pre-amp and the two channels of static are recognized as 6 channels of DTS-encoded audio.
However this process will only work if the player (CD, ATV, PC, etc.) sends a "bit-perfect" 16 bit/44.1 khz data stream to the decoding device. In the case of ATV G2 and G3, as has been discussed elsewhere, the unit resmaples all audio - including 16/44 PCM (Redbook CD) - to 16/48. While this is not a big deal for conventional audio CDs, MP3s, and AAC files, it mangles the fragile DTS datastream and renders it undecodable. The resulting static that you hear is just like the static you would hear if you played a DTS CD on a non-DTS capable system.
Sadly, I'm not aware of any easy way around this. You could use a program like Foobar (and the DTS plugin) to convert your DTS CDs to 6-ch .wav or .flac file. From there you could transcode the file to AC-3 and then mux it into a video container that ATV supports. You may need add a dummy video track, for iTunes/AppleTV to be ok with the file, though I'm not sure. This may be a lot of work.
Sorry for the bad news. I wish that the iTunes/ATV ecosystem had better multi-channel audio support.

How do I get rid of the white noise that plays over my music?

Hey.
I got 5 CDs today and I wanted to upload them onto my iTunes to put on my iPod. But when I put in 4 of the CDs I got white noise over the top of the music making it unlistenable. But the 5th album(Double CD) worked perfectly fine. I know the problem isn't the CDs because I played them through my PS3 and they were absolutly fine. If anyone can help. Its greatly appreciated.
Thank you.
- DowellG8

Go to Edit > Preferences > General > Import Settings and check the box for error correction, and then try one of the problem CDs again.

I made a project with multiple tracks and had it all panned and mixed. Now it's only playing in the right speaker. Not even regestering a left side in the master volume? What happened, how can I get both sides back?

Thank you for that info.
For video, the codec is MPEG-4 Video (XVID) and for audio it says MPEG Audio Layer 1/2/3 (mpga).
There are two issues with that file:
The first is the Xvid CODEC (not meant for editing), and then the MPEG Audio/MPGA. I would convert that file, to something that is more editable.
Good luck,
Hunt

When I open GB in my booth macbook pros and play back my project a short but regular 10 to 20 seconds white noise keeps sounding. does any one know what's going on?s

I was using the garage band normally latetly, recording some projects and all. Sudenly when I open the software or play back, or record a short 4 seconds White noise every 10 or 15 seconds starts buzzing. Does anyone know wth is that?
I've tried re download garage band loops and sound boughtg, re install... booth computers I run the garage band keeps buzzing this annoing white noise.....

Hello Stacey,
What all devices do you have connected?
It sounds like a Ground loop... voltage leaking somewhere.

Will the MBP speakers blow if I play it on max. volume for too long?

Depends what you call too long. Leave any electronics running too long it will eventually break. Might take years, but no mechanical system is immortal. No computer has yet been built around superconductors either, so heat alone would cause circuitry to fail if it is always powered. While leaving on the machine all the time (except for bad weather) is a good idea since Mac OS X is able to do that, individual components I would not always leave in use. Use your energy wisely. Not to mention max volume for too long could theoretically make you deaf if you listen to it all the time.
Use common sense.

Keep hearing white noise when a flash video is playing

Whenever a flash video is playing (ie. Youtube) then I will hear white noise in the foreground and barely hear the original audio in the background. This also happens with facebook notifications and other flash sounds. I have checked my sound card and drivers and also switched the sound card over to see if this solves the problem but it seems to just be linked with Firefox at the moment

hello, maybe it's an issue with the protected mode in the flash plugin - you could try if [https://support.mozilla.org/en-US/kb/flash-113-crashes#w_solution-2-downgrade-to-flash-10-3 downgrading to flash 10.3] (which is still supported) or [http://forums.adobe.com/thread/1018071#TemporaryWorkaround disabling protected mode] makes a difference.
