I'm running Ubuntu 10.10 in a Samsung R510. I've tried to record sound with an external microphone and there have always been a permanent noise accompanying it.I thought it could be the internal microphone, that's causing the noise, but even when I disabled it the noise remains. Or maybe I didn't disable it the right way !

I am having some problems with recording with my laptop. When I try to record something through the laptops mic, usb webcam mic or with desktop recorders audio record feature all playback is too fast (sounds a bit like alvin and the chipmunks :L ) Is anybody else having this problem, or even better know how to fix it ?
Sorry if this has been asked before, I'm running 10.10 and had never tried recording before I upgraded to 10.04. I had the same problem in 10.04 though.

I have recently installed OpenSUSE 11.3. I can play audio files, but there is a problem recording, namely the recording is way too slow. This was tried 3 ways: in Audacity, in Skype (making a test call), and using the arecord command in a console, as root. To make the playback sound normal, I tried taking the already-recorded file and speeding it up in Audacity. It was necessary to speed up the recording by 50%. I've tried updating alsa and other suggestions which I could figure out, and run the scripts for diagnostic information. BTW, I'm using a headset plugged in to standard 1/8 inch mic and speaker jacks, not a USB headset.

I am trying to record using a microphone on a machine running Fedora 14. The microphone itself seems to work fine when plugged into a Windows laptop, and the Linux machine is able to play sound just fine. However, although I can record using the microphone (using arecord or audacity, for example), the recorded audio is super, super quiet. I have run alsamixer, and experimented with every capture source. Anything which had any effect (using arecord -vv to see the dynamic sound level) has been turned up to 100%. Still, recorded audio is barely audible.
I have run:
yum reinstall alsa-utils alsa-plugins-pulseaudio alsa-tools-firmware alsa-firmware alsa-lib
But that made no difference. I ran alsa-info, and the output is here: [URL]. Why my recorded sound is barely audible? My next step is probably going to be to boot to Ubuntu, just to see if it has the same problem.

My wife is taking an online language course that requires Windows in order to record and playback speech (for pronunciation training). I decided the easiest thing to do would be to clone a VM I use on my machine for tasks that can only be accomplished in a Windows environment. I did so, and successfully installed the speech recognition utility on the Windows guest VM. Unfortunately, although the microphone works just fine--I can hear my voice in the headphones--no sound is recorded by the speech recognition utility. Just to be clear, the microphone is fully functional under GNU/Linux. My wife has been using Skype without any issues at all. That is, Skype used to work. Somewhere during the course of trying to resolve the voice recording problem I managed to break Skype. I have no idea how.
It's a long story, but I'll try to be as brief as possible. When I could not get the VM solution to work properly, I thought maybe the problem was with the VM, so I checked the original copy on my own machine. No problem there. Windows sees and hears the microphone just fine (using the testing utility under sound configuration). So how is it possible that the microphone doesn't work in the cloned VM image? Before you stop me, allow me to note that both machines have identical motherboards, and both are configured to use the onboard sound. Sound works on the Linux host and the Windows guest VM. Both sound and microphone work in the original VM image on my machine, but only sound works in the cloned VM on my wife's machine.
If you've followed me down the rabbit hole this far, please continue with me a bit further as things get stranger and stranger. After triple checking all the setting in KMix (I'm running Squeeze/KDE on both machines) to be sure they were identical, I noted that I was unable to view/add/enable the "channel" option on my wife's machine. Why, I have no idea. As I said, the machines are identical as can be both regarding hardware and software. Out of desperation, I decided to set up an account for my wife on my machine. I created her account, made sure she had the necessary audio permissions, then cloned my VM to her account. Same problem.
I would love for someone to point out what I'm missing here. Same hardware, identical VM (clone), same permissions, same sound configurations in KMix and under the Windows guest VM. How is it possible for the microphone to work for me, but not for my wife? Is there some mystery configuration file somewhere that has magically been altered for her account alone? The worst part about this entire process is that I've broken my wife's Skype, which is a big deal seeing as we live in a tiny country in the heart of Africa and cell phone communications are very expensive.

The soundcard was working with the exception of the mic.
So I tried to install linuxant drivers and the installation failed for some reason.
So I uninstalled it. After that my sound card is not being recognized.
Here is the output of the alsa diagnostic script.

I have no HDMI sound for my ASUS ENGT 240 gard. I've used the recommended driver 10.04 offered and currently using the one right from [URL] for 10.04 64 bit. Don't know how to get the boxes around code, but here's what I have for aplay -l, aplay -L, and lspci.

I have an MSI S420 with a realtek alc883 onboard. I upgraded from ubutu 8.04 to 10.4 recently, The sound worked in 8.04 although the mic did't work and the same thing in 8.10 (i went through all upgrades) it stopped working at all in 9.04 onwards.
If i did Lspci -v it did say the name of my card, ( I unmuted all in alsamixer and got the codecs but even a test soud won't work) I also dowloaded a driver from Realtek itself, that didn't work.
Then I edited alsabace.conf some more. I tried every one that could possily be it at [URL] including all that said MSI.
I then tried Lordraidens comprehensive sound guide from step 1 to step 5, I used the module-assistant and istalled a driver that was called "hda-realtek-codec" or so. It was the only appropriate one on the list.
I also run into someoe with thesame problem. [URL]
i think ill give up and use the 8.10 that is still on a other partition

Sound used to work fine on my computer, but one day my headphone jack stopped working -- when I tried to use it, no sound played through the headphones but did play through the computer's speakers.After I tried to fix it, I lost ALL sound on my computer. I noticed in my sound preferences it says "Dummy Output" and no other hardware.The problem seems common -- I've Googled the issue to death and read many threads here about the same problem -- but no matter how many times I've tried, I can't find a solution that works for me.I'm relatively new to Ubuntu and so there's still a great deal of stuff that

I just closed another issue about an unrecognized USB C-Media headset, because the issue seems to be deeper... On an Asus Eee 1001p running Fedora 13, I've run lspci | grep -c audio, which returns 0.
Running alsa-info.sh --no-upload I get a report that tells me that there are no soundcards... Pulseaudio is running though. Also, if I use VirtualBox the sound works fine there (including my USB headset).
I used to have sound, and I'm not sure how it disappeared. I really don't know where to start with this, it's been a pain in the ass all week.

I just installed Ubuntu 9.04 on my laptop then immediately upgraded to Karmic 9.10. Pulseaudio installed by default. There's no sound although the mute button is not checked and the volume slide control is at medium. lspci gives:
00:14.2 Audio device: ATI Technologies IXP SB4x6 Hi Definition audio controller (rev01)
System >Preferences >Sound >Hardware tab: blank window "choose a device to configure" Output tab: "dummy" output stereo
So, it appears that somehow the audio device controller in my laptop is not recognized or its driver disabled, possibly by pulseaudio. Sound works fine in Windows 7 part of this dual-booted laptop.

I've got a problem on my Debian, I've tried installing all the correct alsa packages and all packages that have the word sound or audio description. The problem that is happening here is that when I go into settings and click on sound in Gnome, it appears to have a dummy output and in fact, a few weeks ago, the sound was working properly. Now, I believe, that after an update, the sound card was not recognized. Used the lspci command in root mode, and showed my sound card which is onboard. I'll leave the model below it, because I've tried everything and could not solve anything.
Code: Select allroot@debian:/home/weiller# lspci

For about 3-4 weeks, my file system used space was growing and growing. After some days, I decided to analyze the file system in order to understand what is going on. Well, the results returned that the log files at /var/log ( especially kern.log, syslog and messages ) were the log files that were sucking the free space. I searched if this was some kind of bug but it turned out that if these files are growing, the problem is in the records.
So I picked from the tail of the messages log the last 50 lines and I saw this:
Code:

I am on 64-bit Natty and for the first time since my install a month ago, I have had a system hang requiring a power-off restart. It happened yesterday and a few moments ago.My question is that I want to troubleshoot this myself and wonder if the activities that my system were running just prior to crashing are recorded in a log file somewhere.I used to look int /var/log.messages or /var/log/boot, but this was in the Maverick days.

I tried ubuntu 10.0 yesterday (running from my usb pen) and I liked it. A lot. However, there are a few issues that i need to know if there's any way to solve them, before making the transition: Keyboard keys are swapped; I mean, if I press alt+(anyNumber) I get another character. Why does this happen?-I develop a lot of code in VBA; I tried to record a macro using Open Office Calc, but I got the impression that the code used in the recorded macro is slightly different.

Using Debian Lenny I recorded a wav file with Audacity to burn to a cd with K3b.The problem is when I played the cd with KsCD; it wouldn't stop when it got to the end; it just kept studdering. I didn't have problems using KsCD to play CDs I had ripped and then burned with K3b.Is this a problem with KsCD, or do I need to do something when I finish the file with Audacity?

I recorded some clips on the internet through the sound card withAudacity. I exported the recording as a wave file, and burnt it to a CD. The problem is stop playing. It comes to the end and just repeats the last fraction of a second over and over.I used K3b to burn other audio CDs that I copied and didn't havea problem with KsCD playing them. Is this a problem with Audacity,KsCD or did I do something wrong?I recorded the file; saved project and then exported as a wave file

I want to measure the time it takes to execute a C function. The question is which is the best method to record time. After a lot of searching online, I found two ways [URL]:
a. using clock_gettime(CLOCK_MONOTONIC, &t)
b. using TSC
I call the C function 50 times (recording the time it takes for each call). The average is found only for the last 35 calls.
Using (a), I get:
48345 us
28350 us
28379 us
27716 us
[code]....
Average time for the last 35 loops: 121450.47 microseconds
Using (b), I get:
48130 cycles
28726 cycles
28820 cycles
27421 cycles
[code]....
Average for the last 35 loops: 27236.66 cycles What could be causing the strange value of 3322259 us in method (a)? I could just use method (b) but I would like to know what is going on here... Btw, I am using a desktop - with Linux debian 2.6.26 #1 SMP.

I have a lot of recordings on my mythtv box.i can see/play them fine within the mythfrontend interface, and mythweb loads almost all pages ok (including schedules, guides, etc.), but when I click on 'recorded programs' at the top, Allowed memory size of 33554432 bytes exhausted (tried to allocate 88 bytes) in /usr/ share/ mythtv/mythweb/includes/translate.php on line 142.I've had this error before, and it went away when I purged my list of recordings.

I'm trying to record video off my webcam, and tried two different programs - cheese and wxcam.
I honestly didn't have much luck with cheese - it seemed to work fine, but when it came time to record video, the frame rate dropped to a ridiculous level, making the video completely unusable. I could wave my arm in front of the camera, and it might pick up one frame of that.
Moving on, I tried wxcam, which I like a lot.. however, when I record video with the xvid compression, they play back considerably faster than they were recorded.

Maybe I'm not using the right search terms, but I can't find anything on this. I have a setup of Slackware with Asterisk and FreePBX. I am recording calls on demand and can get to the recordings from the Call Monitor (web interface). I would like to be able to access the recording from the phone (Aastra 57i), much like a voice mail is accessed.

I just installed Ubuntu 11.04. The drive was formatted when I installed so it's 100% Ubuntu. The only major problem I have encountered is that Ubuntu will not recognize my SD cards. I really need to access these cards, all my film footage is on there. I think the internal SD card reader (If such a thing exists) would have been deleted during the installation process. I am a greenthumb to Ubuntu and have never used it before so I am rather stuck...

I have a backup HDD with a different distro for my laptop and i can boot into it via external usb or if swapped into the laptop. This HDD/install in question is debian testing and was working fine, the issue arose suddenly. I was first suspecting a failure of hardware somewhere on the motherboard, but the hdd i was using with an external usb adapter also works when installed into the machine. also, the HDD is recognized once i have booted using the external HDD and distro, but it is not recognized by the bios. so i dunno, my first guess is something became corrupt within the testing install, but i guess its also possible that there is some wrong with the HDD but thats not immediately apparent as all the data is still accessible.
Should also note that the HDD with testing on it is also recognized when connected via the external usb adapter, while booted from alternative distro/HDD.
Also. just tried this, but i can get the testing HDD/disto to boot if connected externally. it was going pretty quick, but there i did catch a line about a corrupt filesystem. any commands to run to see what might be going on?? log files to look at?
