Problem with sound input/output settings

Hello--
Last night, my iBook suddenly stopped playing any sounds at all: itunes, CDs, etc, won't play at all. I looked in system preferences/sound, and the computer told me that there are no input or output devices at all. What's more, the sound seems to me on permanent mute, and it won't allow me to change it at all (F4 and F5 functions just show a "mute" sign under the volume bar). Is this a problem with the software, hardware, or what? Thanks in advance for any advice,
JB Coleman

here is a set of weird but probable solutions. Good luck

Problem with sound in games

Hi all welcome as you can see I'm new to your forum. So I have a problem as it concerns the sound in games.
Namely, I bought a Creative Headset HS-800 Fatality everything good in listening to music, etc.
But when I go to the game, I turned the sound (someone shoots to the left I hear him right, and vice versa.)
Yes, in all games but mostly it is felt such a battlefiel or call of duty.
At first I thought that this is the fault of my sound card but it's not because I was in a mate and in him was the same ... This recently replaced the computer and the same thing.
I came across the net to reverse the channels, but unfortunately I do not know how to set it up.
Here, the data on my computer:
Sound Card Speakers (Realtek High Definitie
Sound Card Realtek Digital Output (Realtek
Sound Card Realtek Digital Output (RCA) (Re
Operating system: Windows 7 64 bit
I would add that in tests Realtek win7 and everything is fine.
Regards and please help as soon as possible.

Do you get any problems with sound in other (older) games? You didn't mention which drivers in particular you updated, but make sure the graphics card's ones are included.

Some progess I see. To be honest, i would not waste your time with trying to connect using wireless.
You are likely to get poor connections and dropping out.
If its working using a cable, then there is no need to bother with giving me the network settings, bu see how it goes, because sometimes giving the TV a static IP address can give better results.
There is an example of a couple of powerline adapters on the diagram below. Just ignore the network switch unless you want to connect other devices which are near to the TV.

Time mismatch with Sound Input Read VI

Hi Folk,
I am acquiring the signal of the PC
sound card with the "Sound Input Read VI" and I have
noticed that between subsequent waveform data packets there are time
mismatch, both overlap and gap.
To point out the observed behavior, I
have posted a modified example, the "Continuous Sound Input.vi". In the example, I have computed the
time difference between the t0 of the actual waveform packet and t0
expected on the basis of the previous waveform packet.
Consistently, in the indicator "Time
series" (Waveform Charts), each time there is a time overlap or
gap the Charts resets it self or presents a gap.
By reading 1 second of data the time
mismatch is about 0.015625 or 0.03125 sec. (both positive and
negative).
The repetition frequency of the time
mismatch decreases as the acquisition sample rate increases.
The amount of the time mismatch seems
to be sample rate invariant.
Do you have any idea from where this
problem is coming out and how to solve it?
Thanks for your help,
Asper

Pre made Labview functions are not some holly grails that is newer to be touched and modified. In fact many included functions in Labview has what I will name as "high flimflam factor" That will say a lot of functions you do not really need. Express VIs are grim examples of this.
Anyway I have made some modifications and removed some babyfat in the sound input VI. Take a look at it. The top level VI is the "time fixed sound.vi" It could be that you will get an error because Labview will not find a DLL. If a DLL is reported missing you will find it in C:\Program files\National Instruments\LabVIEW 2010\resource\lvsound2.dll
Remember to save the modified VIs in a separate folder, and not in the vi.lib folder at all. Be careful so you do not overwrite any Labview function
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Problem with Optical Audio Output

Hi, all. I'm running my audio out through the optical digital output on my Mac Pro. Recently, I've developed a problem with iTunes, where certain tracks are distorted and others play extremely softly. There is no problem when I run the audio out through the headphone jack...it's only a problem through the optical output.
Furthermore, when I go to Audio MIDI setup, it says "Output is not supported" for the optical digital output, when I've read that I should be able to make adjustments to it here.
Does anyone know what might be causing a problem with my optical output? Thanks so much!

Look in iTunes' "Playback" preferences. Try turning off "Crossfade", "Sound Enhancer", and "Sound Check"/

HT1657 I am having problems with sound in my rental movies

We rent movies all the time but lately we are having problems with sound for our movie rentals. We watch the first half hour without a problem than the voice is choppy all the time. Sometimes it is good for five minutes than noting for a while. We have tried everything we could think of with no avail. I could see one movie but the last 5 or so have been the same. Done trying we need to fix this! Help! Any ideas?

First try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears. Try again to see if the problem persists.
If you still have the same issue, it's possible that something is lodged in the earphone jack. This can cause the iPad to think earphones are plugged in when they are not. Use a vacuum to try to suck any dust, lint or other foreign matter from the jack. If that still doesn't work, try CAREULLY using a toothpick.

Try A and B
(A) Restart iPad
1. Hold down the Sleep/Wake button until the red slider appears.
2. Drag the slider to turn off iPad.
3. Turn iPad back on, hold down the Sleep/Wake until the Apple logo appears
(B) Reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected.

[SOLVED]Problem with sound in HDMI

Hello good society of Arch
Now I have problems with sound from HDMI. I use Arch as an tvPc, wasting movies and tv shows on it. I use ALSA and it works well, except of a few files that I have, then there is picture but sound is either twisted or not played at all. It does not matter whether I use vlc or mplayer, I'm experiencing the same problem.
I have not found anything about this with google, other problems have been either hdmi sound working or not, not like it is with me, sometimes it works and sometimes it don't.
I know that the files are ok, I can play them in anther pc I have (also using Arch on that pc).
Does anybody know what the problem might be? What do I have to look at to find out what the problem is? This have been like this for some time now, but I haven't looked into it before, because I don't use TV that muts, but the wife does and when she stats blaming Arch, I have too do something about it.
I have never encountered problem with Arch that i cant solve by using this forum and google
Thanks

I will look at this when i come home from work, thanks.

Problem with sound in games requiring quicktime

I recently purchased CSI 1. I installed the game and the latest version of quicktime player. As soon as the game starts and the first character starts talking the game pauses as if loading and then plays for a second and pauses again for a few seconds. This intermittent sound problem makes it impossible to play the game as the freezing stops everything from functioning. I tried another game that requires quicktime to be installed and that game is pausing the same. Has anyone else had this problem? I have all the latest drivers installed for Vista. Any help would be much appreciated.

Do you get any problems with sound in other (older) games? You didn't mention which drivers in particular you updated, but make sure the graphics card's ones are included.

Problem with sound after update

Hello
After update to 11.3 I have no bass sound in subwoofer in Firefox browser (youtube). I uninstall the newest version and install previous (11.2) and bass plays ok.
My os: Windows 7 x64. Sound card Creative X-fi.

Hello!
My problem is summed up in this topic.
Updated Flash Player with 11.3 this morning (june 12th 2012) and since then my 7.1 Sound System works only 2.1. If i enable EAX Effects, works on 7.1 but since it`s just a room it sounds very odd.
I have no problem with sound on HTML 5 websites for that matter, Winamp, Video Players, games.
Uninstalled Flash Player, sounds work ok without it on different browsers, other than Chrome (since it has FP built in).
I hope for a sollution soon.
Thank you.
*edit*
Untill there is a permanent solution, i found a way to deal with my issue and i hope it will help others.
I personally use Chrome and this is for this browser:
1. Type "about:plugins" w/o the quotation in the navigation bar.
2. On the upper right u will see "Details" click it then find the word "flash", and you will see something like this:
Flash (3 files) - Version: 11,3,300,257
Shockwave Flash 11.3 r300
Name: Shockwave Flash
Description: Shockwave Flash 11.3 r300
Version: 11,3,300,257
3. I say again, this worked for me on Chrome. The 3 files i have, two of them are Version 11,3,300,257 and one is 11.2.31.144
4. Simply disable the lates version 11.3 and enable the previous version 11.2
I hope this helps.

Problem with the input file format to be stored in database

Hi,
I am facing some problem with the input format. I am using the table name as data.employee. But i could not able to process the message forward. I am getting this error,
com.ibm.db2.jcc.c.SqlException: java.sql.Connection.close() requested while a transaction is in progress on the connection.The transaction remains active, and the connection cannot be closed.
Can you please help me prposing a solution for this format.
Thanks,
SOorya

I think you are missing out the COMMIT operation.
At the DB2 end before closing the connection if you do a 'COMMIT' then this may remove your error.
i.e. after you close the Resultset>close the statement object> perform 'COMMIT' operation--> then close the connection.

Partition failed with error input output

Hi All,
I installed a new hard drive (WD 500G) into my 2006 Macbook, Mac OS X 10.4.10. I also increased the RAM to 2G. My Macbook reconized the hard drive. However, I followed the steps below to format the HD, but got the partition failed with error input output msg.
1. Went to Disk Utility, selected the name of new hard drive in the sidebar.
2. Select the Partition tab, and selected 1 partition from the drop down menu.
3. Click Options, then choose GUID .
4. Select Partition
In previous posts someone suggested updating the softward to 10.4.11 or the erasing the HD, but erasing the hard drive would take 13 hours according to my Macbook. Any suggestions? Please Help!

The error usually means the drive is bad. But you can try this:
Erase and Install OS X
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. After formatting has finished quit DU and return to the installer. Install OS X.

Problem with sound since update with 10.4.9 (no problem with with 10.4.7)

Since i update with 10.4.9, I observe some problems with sound that I don't observe with 10.4.7 on an old partition:
1. no more sound when opening excel file with office
2. no more sound with files .rm opened with realplayer
3. no more sound with files .wmv opened with lecteur windows media player.
Ths files are opened normally with 10.4.7 that I conserved on an other partition.

Welcome to Apple Discussion!
This is a well known bug with the optical audio based Macs with a very simple fix:
