Problems with sound recording.

I can't record sound. tried a few desktop session recorder (whatever they are [recordmydesktop & istanbul]).
istanbul didn't give so good output but recordmydesktop -device /dev/dsp informed:
ALSA lib pcm.c:(snd_pcm_open_noupdate) Unknown PCM /dev/dsp
Audacity can't record a thing either. Anyone got problems like this?
lspci | grep Multimedia =>
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 50)
Sound playing works fine..
Anyone else got problems like this? Have I missed something important?
All necessary modules are loaded (atleast I suppose so).
Tell me if you need more info with this one

ive just noticed this also
i run kde using audacity to record from input on sound card VIA 8237
pertinent stuff in .~/.audacity-data/audacity.cfg
PlaybackDevice=OSS: /dev/dsp
RecordingDevice=ALSA: VIA 8237: VIA 8237 (hw:0,1)
i believe the recording device used to be "OSS: /dev/dsp
if i change it here it reverts back to ALSA: VIA 8237: VIA 8237 (hw:0,1)
no matter what i change it to
or in audacity>prefferences i have no choice for recording but
input allows me several choices on main window i can change input devices to record from but none work
when i hit the record button the counter does not move nothing gets recorded though i can hear whats playing on my system
hopefully im not missing anything here if i dont hear anything soon ill file bug
thanks

Problem with sound recording

I am trying to record sound from my microphone. I have just read a part of the tutorial and I did what it said there, but it doesn't work.
The class for recording is here:
private class SoundSender implements Runnable{
        public void run() {
            byte[] bs=new byte[lng];//lng is a constant
            AudioInputStream in = null;
            try {
                TargetDataLine l = getTargetDataLine(f);l.open(f,6*lng);l.start();
                in=new AudioInputStream(l);
            } catch (LineUnavailableException ex) {ex.printStackTrace();}
            while(true){
                try {
                    in.read(bs);
                } catch (IOException ex) {
                    ex.printStackTrace();
                //At his point bs is still filled with zeroes
                //Do something with the contents of bs
    }The getTargetDataLine method is here:
private TargetDataLine getTargetDataLine(AudioFormat format) {
            try {
                DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
                for (Mixer.Info mi : AudioSystem.getMixerInfo()) {
                        TargetDataLine dataline = null;
                            try {
                                Mixer mixer = AudioSystem.getMixer(mi);
                                dataline = (TargetDataLine)mixer.getLine(info);
                                return dataline;
                            catch (Exception e) {}
                            if (dataline != null)
                                try {
                                    dataline.close();
                                catch (Exception e) {}
          catch (Exception e) {}
            return null;
    }

You're not handling your loop correctly, at all.
in.read(bs) is going to return an int, which tells you the number of bytes written into bs. You need this number, for several reasons... I'll call it X for clarity...
(1) The valid "new" data in bs is going to be from 0-X, and beyond X is garbage / old data...
(2) X = -1 is the stopping condition for your loop, not the throwing of an error
(3) X = 0 indicates no data was read, so you should wait for a bit and then try to read again. Not every single read statement will return data...

Problems with sound only on video not audio files

Hello
My first post here. I am having some problems with sound on video files. It is almost no sound, and the sound that is there is only crackling noise. I have the Creative X-treme audio soundcard and have installed the Vista codec pack and the K-lite codec pack. I have also updated the soundcard driver. The thing is that these problems only occure on video files, not on audio files such as mp3's. Can anyone help me?

About alsa dmix, and for the record:
On an Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz, the following are my finding about
quality/cpu when mixing two streams at 44khz:
a snippet from my .asoundrc
#converter "samplerate_best" # perfect: 16%cpu, maybe overkill
#converter "samplerate_medium" # almost perfect: 6%cpu
#converter "samplerate" # good: 4%cpu, definitely usable
#converter "samplerate_linear" # bad: 2%cpu, way better than default wine resampler
#converter "samplerate_order" # very bad: 2%cpu, like the default wine resampler
Here is the reference topic: https://bbs.archlinux.org/viewtopic.php?pid=942724
I may be wrong, but in an opensource world (code reusing), i really doubt pulseaudio could lead to better quality/cpuuse tradeoff.
Pulseaudio, being just another layer atop of alsa, could only lead to higher cpu usage.

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.

Hi there. I have a problem with sound on my 4s. When you move the volume slider up, it sounds well. But when I move the volume slider down I will hear barely and unclear sound in my headphone.I tried different headphones but result is same as old one.Help

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 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.

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.

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.

Problems with ECATT recording using SAPGUI Record

Hello,
I got a problem with my recording. All the prerequisites are done. The problem is, that when the recording is done i don't see the recording in SECATT testcase. Normally when you do a recording you see at the bottom right of the gui a red/white icon active. When i do a recording now, this red/white icon isn't active.
For my it's a very strange error. I hope somebody can give me a hint where i can look,
Thanks in advance.
Kind regards,
Maarten.

Maarten,
First when you start the recording using SAPGUI, you will get the pop-up whether to record this new session. You need to select Yes before continuing your recording.
Secondly check the scripting values in the target system whether it is enabled or disabled using the RZ11 transaction. Mostly SAP Basis team have authorization to change these values for us.
Here is the parameter we need to check in RZ11 - sapgui/user_scripting. It should be TRUE.
Let me know if this helps.

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.

TS1574 My apple macbook pro retina 15'' ME664 has problems with sound.Either there will be no sound at all or at startup there il be very scary and broken sound and afterwards still there would be no sound.Secondly , it does not start in one shot.

My apple macbook pro retina 15'' ME664 has problems with sound.Either there will be no sound at all or at startup there il be very scary and broken sound and afterwards still there would be no sound.Secondly , it does not start in one shot.atleast 2 to 3 times pressing power button for longer time starts it up and afterwards still there will be no sound. Please help

This morning i was not able to hear sound on my recently purchased macbookpro retina 15 inch model.My attempts to resolve this issue by going to system preferences and removing the mute box that was ticked as active. i had downloaded much earlier a mac version of logmein app and noticed that in the sound box noted above that there was a bar indicating that the default was now to logmein. i had never used this app. Why it started today, i have no idea. I moved the logmein application to trash and deleted the app , however it did not remove the default option which still blocked the sound.
Going to a macforum gave the tha anser that to remove the logmein app, it first had to be reinstalled a nd them use the uninstaller option ftrom the dropdown menu. for now that has resolved the failure to allow sound oputput.
