Sound becomes unbalanced using amixer to change volume

I have small dial on the front of my computer (Acer 5920) that maps to XF86AudioRaise and -Lower when turned to the left or right respectively. I mapped it in xbindkeys to the command 'amixer set Master +/-5%'. The only problem is that when raising or lowering the volume, sometimes only one channel gets set because the key presses are registering too fast I guess. I'm wondering if there is a way to keep both channels in sync, or otherwise to slow down the repetitions of that key. Thanks much.

Having just been through a very similar situation with PSE 7, I have two comments:
1) If you choose the "Backup from old NAS using PSE, then restore to new NAS using PSE" technique, I think you have to make sure that the old NAS isn't online during the restore. When I tried it, my old NAS was still online, so all the original file locations in the catalog were still valid, and PSE didn't change them (even though it did put the restored image files on the new NAS). To be fair, I had already tried a number of other mechanisms for fixing my offline files, so maybe I messed something up that prevented the backup/restore approach from working, but it certainly didn't work for me. Also, I tried to restore from //oldnas/photos to //newnas/photos, and all the files ended up in //newnas/photos/oldnas/photos, which certainly wasn't what I had in mind.
2) I ended up fixing my catalog with SQLite Browser, too, but I used a slightly different technique than the one described by the OP. I exported the whole media_table table to CSV, opened it in Excel, did a search and replace from "oldnas" to "newnas", and then built a formula to construct an UPDATE statement for each row, setting the full_filepath and filepath_search_index columns to the values contained in the spreadsheet after the search-and-replace. I then saved those UPDATE statements off to a script and ran it against my catalog with SQLite Browser. I didn't update the volume_id column on the media_table table at all; instead, I hand-edited my volume_table table (using SQLite Browser again) to replace the old nas name with the new one. So far, all indications are that this worked just fine.

Have sound, but lost use of volume keys? DV7T SE

Hello, Windows 7, just noticed as I almost always keep on mute. Mute button still working. Reinstalled sound drivers and updated. Windows updates are up to date. Virus scanned---nothing! On old vaio (sp) this happened and it needed a hot key fix but I can't find something similar for my DV7T SE... Can someone please help me see what I am missing. Again sound is working fine, but the physical volume buttons are not. Thank you

Can you do anything as far as volume adjustment when the headphones are plugged in? Do they work?
As far as seeing other options under the Sound preferences I would think that yes you should be able to see them. Just not able to select them. But I've never had it happen so I can't say for sure.
You might have some luck resetting the PRAM/NVRAM.
The fact that the red glow is coming from the port leads me to believe it's just that little switch is stuck though.

How do I change volume on start up chime

how do I change volume on start up chime? For some reason the volume is very low, almost inaudible. I have external speakers.

The usual setting is based on the last-used Volume in:
System Preferences > Sound
in the running system. Often, just setting the System Volume high enough will mean the chime is at a similar Volume.
The problem is that now sounds and speakers are under software control, and muting at Startup and what Volume sounds should be played through what ouputs at Startup has become more complex.

Sound leak when using unsigned

I've generated a simple test case which should make this pretty straightforward. I'm using Linux Ubuntu 11.04 with pulseaudio, if it makes any difference.
Basically, I generate a very simple tonal sound for the musical note A3 using Java's java.sound.sampled APIs, and Clip to open and play it.
That's all well and good, but to avoid leaking sound resources, I have to listen to the Clip (or Line) for a STOP event, and then close it. That's fine too. If I play two sounds at the same time and do this, it works fine, too...
unless the sound encoding is unsigned. For some reason, switching it from signed to unsigned (and translating the tonal wave appropriately) makes me only able to close one of the Lines, and the other one goes rogue.
Here's my code:

     }A few modifications you can make to see what I'm talking about:
Line 21, change signed to true, and everything works great.
Line 92, assuming signed is false, comment out this line, where I close the stream, and re-run. You will observe 2 Stop events. Enable it again and you will observe only 1 Stop event.
Am I doing something wrong, or is Java's sound system just that deplorable?

Unless you are playing sound to bats using hardware much better than I am then anything higher than a sample rate of 44 KHz is a waste of time. At my age the highest frequency I can hear is about 8 KHz so any sample rate much above 16 KHz is too high.
Makes sense.
have noticed varying behaviors.
I'm fairly new to this sound stuff, and at this point I'm just trying to get it to work. Get what to work? You have not really described, or a least I have not understood, exactly what you are trying to do. You have a clip of sound you are trying to play more than once but you are trying to "avoid leaking sound resources". Can you explain what you mean by this and why you think it necessary; a reference to some Java sound documentation would maybe help us understand.
Well, here's the sound documentation that I'm basing my code off of: http://download.oracle.com/javase/1.5.0/docs/guide/sound/programmer_guide/chapter4.html (and chapter 3)
Basically, my program has a play button that will play a sound that the user has loaded in (complex encodings or formats are not a concern currently). I need to be able to figure out how to handle the user clicking on the button multiple times. I would at least expect an average system to be able to play the sound twice concurrently (overlapping). Maybe I just have the wrong concept when I talk about "sound resources", but it seems like I run into problems down the road, like on my computer, after I've played the sound 30 times, it starts erroring, or if I try to play the sound twice, and then once more after they're done, it causes the application to hang. To me, this seems like it's looking for available lines, and just plum running out, or choosing a line it thinks is available, and hitting a wall. Idunno.
I have a .wav file that uses PCI Unsigned 8000 Hz that was exhibiting this problem. I don't think the '.wav' file was not exhibiting the problem I think your code is/was .
Fair enough. It's easier to fix the code then to expect to have certain types of wavs.
Ultimately it leads to the application hanging entirely,
I would be interested in seeing an SSCCE ( http://pscode.org/sscce.html ) that exhibits this since I have never met it.
I think it would be wise to deal with one problem at a time for now. The program that exhibits it is large and would be time-consuming to simplify. I figure the problems are interrelated, so if we can fix the current problem, the apparent freezing issue should resolve itself as well. If not, then I can make an SSCCE for that.
and I have to forcibly quit the JVM. Being able to close all sounds completely curtails that "feature", but it's apparently not an option for unsigned encodings.Since the difference between the two is just a toggle of one bit I don't really believe that this is a signed/unsigned problem. I believe there is something more fundamental to explain the problem. I expected as much. It's always nice to be able to fix one's own code/thinking than to hit a roadblock with the limitations of an API.
>>
Plus, your exception doesn't sound that desirable either.I didn't say it was desirable - I was just saying what I observed. My exception seems logical since the line I was trying to open was already open so a LineUnavailableException makes sense.I suppose so, yes. And I'm guessing your system is more than capable of playing two lines concurrently, if done correctly.
I suppose the problem that you're seeing (and probably mine, too) is that it's trying to recycle the Line (just a guess - I could be completely off). For whatever reason, mine lets me play the recycled line twice, but yours doesn't. Both ways cause issues.
I suppose this tells me that if I want to play another sound concurrently, I need another line, not a recycled one. Does that seem about right? If so, how might I go about doing that?
If not, perhaps I'm a little thick and need some hints.
In short, the problem is I would like to be able to play two sounds concurrently (seems like a reasonable enough request), but either I can't using my current code code (as you've seen), or it causes other issues (my side). So I'd like to know how to fix the code to enable this.
Greatly appreciated.

Confusing problem with changing volume in alsa

hello,
i searched the forum and google, but didn't find anyone that has the same problem as me.
My sound generelly works, BUT the most time i can't change the volume because there is no PCM in amixer / alsamixer / gnome volume control. But after a while, there is a PCM option available. I tried to find out in which case the PCM option appears..but i didn't find any contexts..
I noticed, that instead of a "Master" slider, there is just a "Master Mono" slider...But when changing it the sound doesn't change..so i need PCM.
My soundcard is onboard AC 97 SiS SI7012 on AsRock K7S41GX.
If you need any further information for analysis let me know.
minus

I have the same board, but I gave up on the onboard stuff ages ago: bought a cheap PCI soundcard and NIC, and an AGP graphics card. Frankly, it was just easier.
I know this isn't very helpful. All I'm saying is that the K7S41GX seems to be a very troublesome board under Linux. Have you got the onboard ethernet working at all, or is that just mine?

When I put on my headphones, sound becomes barely audible, what do I do?!?!?

Hmm, my first time ACTUALLY having probs with my iPad, I am a little bit nervous.
Okey, I tried to change volume when I had my headphones on ( I believe there's two parts, types of volume, one when it's the built-in speaker, other is when the headphones are on) volume changed so little, I got startled that my headphones don't work. But they do work properly on my MP4 player and they used to work fine on my iPad. Then getting more nervous, I went to General then Sound. There I scrolled the volume bar to full, still no difference. Urgent appeal to all experienced users!!!!!

Can't change volume on keyboard

hi!
i just recently updated my ibook's software (10 dec. 2007) and after restarting, i found that i couldn't use the f4 and f5 buttons to change the volume. i tried going to system preferences but there was nothing there. the only way to change the volume is for me to manually click on the volume button in the menu bar or open up system preferences.
is there some way to change whatever setting it may be on so that i can control the volume using the keyboard?
the sound works fine. it's just the volume thing that bothers me.
to whoever who may reply, thank you!

try holding down the function key, and then pressing the volume buttons. if that is the problem than you can change the default in system preferences->keyboard and mouse. uncheck the box that says us f1, f2, ... as standard function keys.

nno sound when I use in app streaming

Hello Saranginotes,
After reviewing your post, I have located an article that can help with iOS audio issues. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker
Can't hear anything from the built-in speaker of your iPhone, iPad, or iPod touch? Maybe you can hear, but the sound is distorted, muffled, intermittent. Or maybe you hear static or crackling noises. If your iOS device has any of these issues, follow these steps.
Follow these steps and test the sound after each one.
Go to Settings > Sounds and drag the Ringer And Alerts slider to turn the volume up.
If you can hear sound from the speaker, then the speaker works. Continue with these steps to find the setting or switch that's affecting the sound. If you can't hear sound from the speaker, contact Apple Support.
Make sure the Ring/Silent switch is set to ring. If you can see orange, it's set to silent.
Restart your device.
Open an app that has music or sound effects. Adjust the volume with the volume buttons or the slider in Control Center.
Go to Settings > Bluetooth and turn off Bluetooth.
If there's still no sound, connect a headset. If you can hear sound through the headset, remove it and clear any dust or debris from the headset jack of your device.
If the device is in a case, make sure that the case doesn't block the speaker.
Use a brush to gently clear any debris from the speaker and Lightning connector (or 30-pin dock connector). The brush should be clean and dry and have soft bristles.
Update your device to the latest version of iOS.
If you followed these steps and still hear no sound or distorted sound, contact Apple Support.
Thank you for contributing to Apple Support Communities.
Cheers,

How do you change volume permissions with Solaris Volume Manager?

(Previously posted in "Talk to the Sysop" - no replies)
I'm trying to set up Solaris 9 to run Oracle on raw partitions. I have my design nailed down and I have built all the raw partitions I need as soft partitions on top of RAID 1 volumes. All this is built using Solaris Volume Manager (SVM).
However, all the partitions are still owned by root. Before I can create my Oracle database, I need to change the owner of the Oracle partitions to oracle:oinstall. The only reference I found telling me how to do this was in a Sun Blueprint and it essentially said "You can't change volume permissions directly or permanently using SVM and chown will only remain effective until the next reboot. To make the changes permanent, you must modify /etc/minor_perm". Unfortunately, I can't find an example of how to do this anywhere and the online man pages are not particularly helpful (at least not to me).
I'd appreciate a quick pointer, either to a good online resource or, even better, a simple example. For background, the volumes Oracle needs to own are:
/dev/md/rdsk/d101-109
/dev/md/rdsk/d201-203
/dev/md/rdsk/d301-303
/dev/md/rdsk/d401-403
/dev/md/rdsk/d501-505
I provide this information because I'd like to assign some, but not all, of the devices under /dev/md/rdsk to the oracle user and I was hoping some smart person out there could illustrate an approach using simle regular expressions, at which I'm horribly poor.
Thanks in advance,
Adrian

Ron, I feel your pain. I just came from an HTC also and a lot of stuff with this iPhone is bugging the crap out of me. Who makes a phone where you can't adjust the ringer and alert volumes independently? Instead, I have to adjust the alert volume when it is active. C'mon guys. Get with the program. You won a bunch of Android users over with the 4S, but you're going to chase us all back when we're done with our contract. Frustrating.

A glitch in my use of the change event

I have a script in the change event of a drop down list field that works when a certain choice is made then another field becomes visible. I am trying to get that field to become visible when when a record from a database populates the field the correct value. Right now all that happens is the drop down field shows the correct value but the field in question isn't visible.
Here is the code I am using for the change event.
var contractLangs = xfa.event.newText;
if (contractLangs == "Creative Works Unlimited")
xfa.form.form1.MainPageSF.ContractSF.ContractLanguageSF.presence = "visible";
else
xfa.form.form1.MainPageSF.ContractSF.ContractLanguageSF.presence = "hidden";
I can't figure out how to get the field to become visible when right value goes into the drop down field.

I don't think I have been explaining this very well so here is another try.
I have a Drop-down List called "ContractTypeList" that has three items in the list;
Limited Permission
Creative Works Unlimited
Commission for Creative Works
If Creative Works Unlimited is chosen a hidden Drop-down List called "ContractLanguageList" becomes visible otherwise if either of the other two are chosen then it is hidden.
I would like the "ContractLanguageList" to be hidden or shown depending on which item shows in the Drop-down List when I cycle through records in a database. Right now it only works with user interaction.
I'm not sure what to do. I have been using the line, xfa.even.newText. If anyone can help me out it would most appreciated.

How to use type cast change string to number(dbl)?can it work?

how to use type cast change string to number(dbl)?can it work?

Do you want to Type Cast (function in the Advanced >> Data Manipulation palette) or Convert (functions in the String >> String/Number Conversion palette)?
2 simple examples:
"1" cast as I8 = 49 or 31 hex.
"1" converted to decimal = 1.
"20" cast as I16 = 12848 or 3230 hex.
"20" converted to decimal = 20.
Note that type casting a string to an integer results in a byte by byte conversion to the ASCII values.
32 hex is an ASCII "2" and 30 hex is an ASCII "0" so "20" cast as I16 becomes 3230 hex.
When type casting a string to a double, the string must conform the the IEEE 32 bit floating point representation, which is typically not easy to enter from the keyboard.
See tha attached LabView 6.1 example.

Earpod headset doesn't change volume when iPhone 5 is on charge?

When my iPhone is put on charge my headset's volume buttons don't change volume, however when I take the phone off charge it starts working again. It is not a hardware issue as I have recently got my earpods replaced on warranty, I suspect it's to do with the iOS's accessory feature mistaking the charger for a dock of some kind and disabling the headphones from interacting. I am currently on iOS 6.1. Thanks, Oliver
