Sound problems on Linux

This is a summary message of the status of sound on recent Linux distributions as posted on Ubuntu, OpenSUSE and other forums.
Linux recognizes the codec as Realtek ALC888. People have reported two options:
- use snd-hda-intel module with "options model=3stack-6ch" to get a working 6 channel sound setup. You can use "speaker-test -Dplug:surround51 -c6 -twav" to test if all 6 channels are working.
** Headphone jack sense does not work. If headphone is inserted, sounds comes out from both the headphones and external speakers. And the speakers cannot be turned off by using any options in the mixer.
- use snd-hda-intel module with "options model=lenovo-ms7195-dig" to a working headphone/speaker setup. Speakers are silenced when headphone is inserted.
** Not all of the 6 channels work (as tested using speaker-test). IIRC, only 4 of the 6 channels work (no sound for center and LFE).
Is there any known workaround to get both a working 5.1 setup and headphone jack sense ? This happens with Alsa-1.0.16.
Thanks,

i had put ubuntu on my y510 it didnt work well at all so i got rid of it... i looked around a bit nobody really offers generic drivers sooo i uno waht to say...

Will BIOS update help wtih sound problem?

I have a problem getting sound working with linux on a 3000 (an N200 0769 in my case) that many other people have reported: sound only works with ACPI off.
I asked for help on the Mandriva forums and was told to check if there are any relevant BIOS updates. the readme for the latest BIOS does not list any changes to do with either sound or ACPI so it appears unlikely.
However, my BIOS reports itself (during bootup) as 2.03, and it appears to be 68ET31WW. This does not appear in the summary of changes in the readme which jumps from 1.02 to 2.02!
Does anyone know what has changed between 2.03/68ET31WW and the latest (3.03/68ET35WW)?

It hasn't helped my CMX 3200C2.. same issues as you describe.. no joy at anything other than slow...

please tell me what is problem in My Laptop. i have window 7 ultimate operating system.
Please help me sir

What sound problem - no sound on anything, no sound on some apps ?
Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Desperately need some help!! iTunes/Quicktime/iChat/Sound problems....

So, yesterday, I was online, on google video, and when I pressed play on the video, there was no sound, but the video worked...the same was true on every video site i checked. My computer volume was at max, and I even tested the speakers to make sure they were on, and they indeed were.
I thought that was odd...but then the problems really started.....
After that, I clicked on my iChat icon. It bounced once, and did not open. The same thing happened when I clicked on iTunes. 1 bounce, and then nothing. I checked to make sure all of my iTunes mp3 files were on my computer....they indeed are all still here, bit nothing I can do opens iTunes. I've run disc utilities, and disc repair...according to that, everything is peachy-keen on my computer.....but iChat and iTunes STILL will not open, and there is still no sound on anything.
Now, i'm leaning towards the archive and install option....or even just backing up what I want to save, wiping the drive, and starting from scratch.....but i'd really like to not have that happen.
(and, as a side question, if all I want to save are images, several documents, and many mp3 files, would everything be okay if I just backed them up on an external drive, and then loaded them back on to my computer after reinstalling OS X?)
Sorry about the length of this, but I am at my wit's end, and I have no idea what to do.

by third-party, do you mean things I installed that are not manufactured by mac? If that is the case, I have microsoft office, Smart Music, Flip4mac, and Senuti.
I got rid of Flip4Mac to see if that affected my sound problems, but it did not. So, as of now, my problem remains the same...

Sound problems on ProBook 6550b, running on Win 7 Pro x32bit..

I have been getting very similar sound problems on my notebook as posted by most: internal speakers work on original Audio HD drivers, but there is no sound when I connect external speakers or headphones. I up-graded the audio drivers to IDT HD Audio and I get sound coming from external speakers or headphones, but nothing from internal speakers.
I have tried everything from reporting the problem on public forums, live help, and done this or that, but nothing changes. It's so very clear to me that it has to do with audio drivers, which don't seem to work appropriately to cover all aspects of sound output.
I also, often, get this loud, weird, irritating noise and a frozen PC when I am playing music with the notebook, while on the internet. The best I do is not to do both at the same time. I have seen similar problems on blogs, but tangible solutions are NOT offered!!!! Please help...

Audio Switching coudl be due to several reason. if you have tried latest audio drivers and latest Video drivers from hp.com, i suggest you to get audio board replaced for your computer.
Hope it helps.

Path problem in linux

hi,
i have problem with file path accessing in linux. my java class is accessing a abc.cvs file and and getting all data. it is working fine in windows xp. but i run this same file in linux it does not access the abc.cvs file and does not get any data.
my project structure
Search
abc.cvs
search.SearchMain
i am sccessing this cvs file in this SearchMain class by this way file name = "abc.cvs"
It is working fine with window but problem with linux.
when i place this abc.cvs in a folder as "./data/abc.cvs" also working fine with windows but not in linux.
I am new for linux.
Please give me solution.
Thanks in advance
Ravi

There shouldn't be any differences between Linux and Windows here, it's all about your environment. In order to access abc.cvs class (I presume that abc is package name) from search.SearchMain class you need to have a directory (or .jar file) containing abc/cvs.class in your CLASSPATH environment variable.
Try setting it with
export CLASSPATH=your_dir_or_jar_file:$CLASSPATH
and then running the app again.

File problem in linux OS.

hi,
I am creating one jar file . In my program, when I click one survey menu in my GUI,it will collect information from remote device and store it in log file located LOG folder. In my case, I put one folder " Cal" and inside it I put myjar.jar file and that log (LOG) folder.
In Windows, when I click survey menu in GUI, the log information automatically stored in log foder as survey.txt file. And also, i create one show dialog box to show where the log file located.
my code is,
String ss=new String(" HIllo"+"loginfo" );
                 byte b[]=ss.getBytes ();
                       OutputStream f0=new FileOutputStream               ("LOG/survey.log",true);
                       f0.write(b);
                       f0.flush();
                       f0.close ();    the above code is file writing in txt file.
for display dialog box,
if(source==Survey)
                File file = new File("LOG/Survey.log");
                file = file.getAbsoluteFile();
                javax.swing.JOptionPane.showMessageDialog(MainFrame, "The LOG FILE is stored at -- \t \t"+file);
             }In windows, where can i install that Cal folder (inside it JAR file and LOG folder), and click that jar , all are working fine. The log file stored correctly inLOG folder and dialog box show the located path.
eg. log file stored at D:/sbk/Cal/LOG/survey.log
But my problem in linux.
when i click survey menu, it will defaultly stored in root folder and log folder. Actually i am not creating LOG folder in root folder.
I am changing file writer as , to store that JAR folder and want to store that log file in home directory.
if(no_of_ssid!=null){
                String ss=new String(""HIllo"+"loginfo\n" );          May
                 byte b[]=ss.getBytes ();
                       OutputStream f0=new FileOutputStream ("/home/Cal/LOG/Survey.log",true);
                       f0.write(b);
                       f0.flush();
                       f0.close ();    but, now also that file stored in rot directory.
what can I do.
how can I store log file in home/Cal/Log folder in Linux.
any one help this problem

Unicode filename problems in linux

I'm running into a problem in linux (Ubuntu). The following test code will throw an exception at the "FileInputStream fis... " line with the file has a unicode filename. However, Windows passes this without problems.
try {
     File dir = new File("a directory that exists");
     File[] files = dir.listFiles(); //get file list
     for (int i = 0; i < files.length; ++i) {
          System.out.println("file " + files.getAbsolutePath());
          FileInputStream fis = new FileInputStream(files[i]);
} catch (Exception e) {
     System.out.println("Exception: " + e.getMessage());
Does anyone know how to fix this? Thanks!

But the characters are actually chinese. And since
it's on Ubuntu, it would be in UTF-8 encoding
wouldn't it?
The characters display fine in ubuntu but when I try
to read them in using FileInputStream, it fails for
some filenames with strange characters.
I just don't understand why some characters make it
fail and others are fine. It seems that it should
all work or all not work? Perhaps I'm wrong.On my Fedora Core 6,
the result of
echo $LANG
is:
ja_JP.UTF-8
And I tried your program on a directory that has 百度MP3��全.txt file in it.
import java.io.*;
public class AlsKdj{
public static void main(String[] args){
    try {
      File dir = new File(".");
      File[] files = dir.listFiles();
      for (int i = 0; i < files.length; ++i) {
        System.out.println("file " + files.getAbsolutePath());
FileInputStream fis = new FileInputStream(files[i]);
System.out.println(" " + fis.toString());
catch (Exception e) {
e.printStackTrace();
The output from the program is:
file /root/test/./AlsKdj.class
java.io.FileInputStream@1a46e30
file /root/test/./百度MP3��全.txt
java.io.FileInputStream@3e25a5
file /root/test/./bbs.txt
java.io.FileInputStream@19821f
file /root/test/./WMP.txt
java.io.FileInputStream@addbf1As shown above, the result is normal if LANG is really UTF-8.
My Java version is:
java version "1.6.0_01"
Java(TM) SE Runtime Environment (build 1.6.0_01-b06)
Java HotSpot(TM) Client VM (build 1.6.0_01-b06, mixed mode, sharing)

Any resolution to the sound problem?

I have been having the same sound problem with my Mid 2010 Mac Pro tower ever since I got it. I have been in touch with Apple and have been told that they are familiar with the problem, but that they are still working on a fix. The problem is that I have external speakers, and every time I shut down and then start up again, I have to go to preferences and physically change the sound output to go to the speakers. I have also been tole that the Mac is supposed to sense the external speakers and go directly to them.
Is there anybody else out there with this problem, and has been able to resolve it?
Thank you.

I have a 2010 Mac Pro and use the stereo line out jack in the back of my machine for my speakers with no problem. I don't recall any problems setting it up. But check the Audio MIDI Setup (in your utilities folder) to see if you can set it from there (should be able to). Not sure why the preference wouldn't stick. And I don't believe there is automatic detection of an attached sound output device where the sound preference switches to that (unless maybe the front jack which I never use).

Please help iPhone 5 sound problems

Sound Problems on iPad: how to fix, easy [video]

Hi dear iPad user,
Most people will, eventually, have sound problems: the cause can be complex as a 'miss-behaved' app that messes the sound engine or as simple as the iPad being forgotten on Mute/Volume Down.
I used to help family and friends to fix their iPads' sound problems by sending them 'text' instruction steps... lots of times they ended up calling me on the phone...
So I made a video (short: 1m40s):
https://www.youtube.com/watch?v=FjBP-Ncj_fE
It shows:
how to unmute the sound (even if the side-switch locks the rotation of the screen)
how to put volume up
how to close all the apps (in the case there is an App messing with the sound system)
how to reboot the iPad (ultimatelly fixes hard cases of messed sound system)
What it won't fix: if you have a hardware problem...
If you do all the steps and you get NO SOUND AT ALL, please, try also checking if you car listen sounds using a HEADPHONE (you know are working conditions). If you can listen to sounds in the headphone but no sound at all in the iPad's built in speaker, well, there might be a hardware problem and you should look for help on an Apple Retail Store or other official technical support available at your location.
Hope this helps!
Everson.

UPDATE: fixing iPad Sound after iOS 7
http://youtu.be/SDf1LDcE95Q
(1min 36sec)
It covers the basics:
checking side-switch / mute / "Control Center"
volume all up
...and also the worst cases:
closing all apps (for rare cases when a single app might render the sound system instable)
rebooting the iPad
So, don't get desparete: try the things in the video.
There are people who reported having forgotten an audio-bluetooth connection activated with a turned-off sound-system or speakers... or forgot Air-Play turned on... so be sure you disengage bluetooth and/or airplay.
On the 'hardware side', dirty dock connector (30 pin) can make the iPad 'think' it is connected to external audio - if so, cleaning it with a dry toothbrush can fix. Also, moisture in the headphones connector can make the iPad switch to 'headphones' even without headphones connected, making it silent: check if you can hear things with headphones plugged in - if so, try gently inserting and removing headphones a few times and check if you get sound back to iPad's speakers alone.
Good luck to everybody! Audio problems are quite common - fontunately they are easy to fix.

After reformatting my laptop and re installing xp pro everything works but my sound,,, before anyone suggesting I should renew my sound drivers or even update my BIOS let me mention that I have already taken those stept, the Mic works but I have no sound coming out of the laptop.....
Any Ideas????

Hi Nick,
Sorry for the long delay I only just noticed your post. Easily done if you post in the middle of another thread.
To diagnose your sound problem the best approach is to systematically check (and isolate) each possible problem area until the culprit is found. For sound problems follow the sequence :-
1. Check Hardware. If you have a manual control check that it is turned fully on (this may be a wheel or knob somewhere on your notebook). There is no point carrying on if this is turned down/off.
2. Check Software. This is where the fun begins.
2.1 Check the sound properties (available from Control Panel) and make sure that the MUTE box is not ticked.
2.2 Check the individual volume levels shown on the sound properties box. Set them all to maximum.
2.3 Select Device Manager (from Control Panel) and check the entry for Sound/audio devices. Select your sound device and click the 'troubleshooting' option. Follow the on-screen checks.
2.4 If you still have no sound deinstall the sound device (from ADD/REMOVE hardware) and reboot. The system should detect the sound device and re-install it)
2.5 Finally download and reinstall the correct device drivers for your sound devive from the Toshiba web-site.
2.6 If you still have no sound after all of the above then I would recommend a complete re-install of your system from the Toshiba Recovery CDs. and if that does not correct the problem then you will need to take it to a Service Agent for them to sort it out.
