View 2 RepliesI am trying to record a video clip, using my webcam, but sound synchronisation is always poor. I have used Cheese, UCView and VLC. One possible cause is explained in the reply to this question, but I am not an expert. In desperation, I now want to try ffmpeg. The ffmpeg documentation gives the following example
Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
My system has no /dev/dsp, but does have /dev/snd with these files
Code:
$ ls /dev/snd

I am trying to record a video clip, using my webcam, but sound synchronisation is always poor. I have used Cheese, UCView and VLC. One possible cause is explained in the reply to this question, but I am not an expert. In desperation, I now want to try ffmpeg. The ffmpeg documentation gives the following example
Code:
ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
I want to use alsa, not oss, but need to know the alsa input device name (/dev/dsp is created by loading the oss modules). By running alsamixer, I have nutted out that /dev/snd/controlC0 refers to the HDA Intel sound card, ~controlC1 is my USB webcam and ~controlC29 is the microphone built in to my notebook, but these are control devices, not inputs.
[Code]...
However, that does not explain which device is the mic built in to the laptop: by my calculation, it should be pcmC0D1c, but there is no such device. In /proc/asound/card0/pcm0c/ I have directories for sub0 and sub1, which I am guessing relate to the mic jack and inbuilt mic respectively. Do two physical mics share one logical device somehow? I am starting to really confuse myself, if you haven't guessed that already.
I think my question boils down to "How do I record a video clip on Fedora 14 using ffmpeg?", but I am specifically interested in knowing how to specify each of the alsa sound input devices for my system.
I use a USB webcam with a built in microphone. It works fine, but every time I plug it in I have to go to sound properties and select it as the input device. There are no other input devices present on my system. Since it's the only one there, is there any way to get it to automatically select when I plug it in? If not, I think that would be good functionality to add. Does anyone know who or what team to contact about that?

When I use
Code:

and also i checked cable device and everything. And it was working till I last hour. I rebooted computer then there's some problem, I haven't change anything before or after rebooting.
I'm using FFADO on JACK in order to use my firewire device (M-Audio Profire 610) and I seem to have the opposite issue as others who have similar problems. Everything starts up fine, and I can record audio into Ardour using my inputs, but I can't get any output from any of my 8 line outs.
I've checked the connections using QjackCtl, and I tried to route audio from another program (Audacious) but I can't seem to pull audio out of the device (or the computer won't send my device audio?).
I can't use my line-in/microphone jack. In system-management-sound input tab there is no input device listed, and the input controls are grayed-out. sudo lshw -C sound produced:
description: Audio device
product: N10/ICH 7 Family High Definition Audio Controller

I'm having here annoying "problem" with my webcamera. Everytime I want to use it as a microphone it needs to be switched manually in sound settings menu. It's not a big deal but I would really rather let it be switched automatically like plug and play or something like that.
View 8 Replies View RelatedI have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.
View 4 Replies View RelatedI've never tried getting my mic to work in linux up until now. For some reason I can't get any sound to come through on the input. I don't really mess with my sound settings so my knowledge is pretty limited in this area. I have a Creative Audigy 2 card and it seems to be using PulseAudio. alsamixer, aplay etc. all seem to NOT be installed. I can edit volume one of two ways. The gnome sound prefrecnes or using pacmd. I'm kind of at a loss here and my searches haven't turned up anything useful as they refer to alsamixer etc.
View 2 Replies View RelatedI had have this problem since I first install Karmic back in February. Now I installed 10.04 and the problem with the input sound is still here.
Plain simple: there is no input sound at all.
I already checked the alsamixer controls at the terminal and everything seems normal. I have a sonny Vaio laptop model VPCF11FD.
I'm using a Dell Vostro 1700 with Ubuntu Lucid Lynx and nothing I do with the sound preferences changes anything. I've also tried running alsamixer. no luck.

View 2 Replies View RelatedI have the following problem. As trying to record with an analog microphone through arecord, audacity, gnome-sound-recorder i can get no sound captured. Then i've tried skype where the volume is too low and the sound is distorted.
Until i was using an usb webcam with mic integrated i had no problem using skype but with a simple usb mic i can't get sound recorded. I've tested 3 different mic in a windows os and in opensuse 11.3 on the same pc with a double partition. All of them are working fine with win but not with opensuse.
Bellow i' m providing some info as requested in a similar post from oldcpu
11.3 x86-64 & vt1828s - No sound from mic or line in code...
i've tried to upload to the alsa site but it gave me only a .txt output therefore, i've put it on pastebin.
Sound output works without problems. The only problem is the mic input.
When the volume of the mic is at 100% i can here sound from the speakers, what should mean that the mic is working, but it's not capturing anything. I've checked the mixers from yast>harware>sound and seem to be all up as in alsamixer in terminal and kmix.
I'd like to add that i'm using opensuse 11.3 with kde 4.5.5 updated today through the stable repositories and to have even updated alsa, as proposed always from oldcpu in the same post mentioned in the beginning of this post, from the following site and for my specific kernel.
I have had trouble with my sound since installing. I have been able to get output sounds to work by setting my sound output to:Internal Audio Digital Stereo (IEC95 instead of:However, my microphone does not work. I know it was working earlier on but I can't figure out what the settings were at that time.Are there any ideas on what I can try to get the input and output audio working correctly?
View 1 Replies View RelatedI'm using a terratec EWX 24 96 sound card with ubuntu studio, and I have sound with the digital output, I have no sound with the digital input.
I had sound with the same configuration in Windows XP, and all the hardware is ok.
I think I have no sound at all, with Ardour or Rosegarden, that's like if the digital input was not here in jack.
I've tried to look for a solution for a few days now, and haven't had any results so far. I really hope you can help me so I can get to talk with my girlfriend.I'm running Lubuntu with 10.04 LTS, and alsa version 1.0.23 on Samsung NC10.Hardware works, soundcard is recognized by the OS, modules are loaded, alsamixer volume up and unmuted, sound output is ok, arecord or sound recorder don't get input.
- The microphone hardware works. Having the volumes up I hear the noise from the speakers when tapping the microphone.
- Soundcard is recognized by OS (and like I said, music and all other sound output is perfectly fine)
I am sure this has been asked repeatedly, but I cannot find it anywhere. I have my TV's sound plugged into my mic input, and can see it registering a signal but I cannot get it to play out through my speakers. I have done this on older versions, but I cant remember the name of the mixer that allowed me to do it.
View 5 Replies View RelatedFor some reason my soundcard is recording every playback sound. This become apparent when I was trying to make a Skype call and the other people couldn't hear me. I checked my sound preferences and noted that the input was recording what they say (they could hear an echo). Also if I played back anything it would redirect to them. This has never happened to me and I've made a lot of calls in the past.
I tested with Audacity and it records fine, but when I play back the recording, it redirects to the input channel so it's not a problem with Skype. (my soundcard is a VIA VT1708B 8-Ch). Somewhere I read that the output of aplay -l is useful.
Here it is:
I used to be able to use Skype without a problem. I must have played with something as it now doesn't allow me to both use a microphone and external speakers at the same time.I go into sound setting and I am able to test the microphone (works) but then the speakers don't show, if I reverse the tests then the opposite happens.
View 1 Replies View RelatedIn Lucid, Logitech Pro 9000 webcam worked fine until the kernel was upgraded to 2.6.32-24 recently. The usb sound was not listed in /proc/asound/cards. I had to boot from 2.6.32-23 to make it work.
UPDATE: the recent upgrade to 2.6.32-25 fixed this problem.
I'm thinking of getting a new multiple input sound card for my PC running 10.10
I want to be able to record at least 4 channels simutainiously and have good drivers in Ubuntu for it.
I am using ubuntu 9.10 (kernel 2.6.31-9-rt) and an M-Audio Delta 1010 PCI sound card, and trying to get MIDI inputs and outputs to work on this sound card.I have Jack installed and working. MIDI signals from virtual keyboard or a MIDI player can be routed to fluidsynth, and fluidsynth's audio can be played back through the outputs of the delta 1010.I can use a MIDI sequencer (e.g. rosegarden or qtractor) to record MIDI from virtual keyboard, with jack handling the routing.
But, no matter how I configure the connections in jack, I can't get any signals from the "MIDI In" port on the sound card.Does anybody have some thoughts on how to fix this? Where is the disconnect between the delta 1010 and qtractor? I am concerned also that the "MIDI In" LED on the front panel of the Delta 1010 never blinks. There must be some basic ALSA configuration that needs to be done to activate and use these MIDI ports, or something. I've been trying to figure it out for days.
For the last 3 release all my hardware have been working like a charm. But after upgrading to Lycid I have problems with skype. I fix the camera issues with the following command
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype
But the sound of my microphone is totally jagged. I have an ICH8 Intel integrated card. I have worked the last 2 years (with an ocasionally glith in the volume) but not having Mic is a real PITAo what can I try to fix it? Please, don't tell me "remove all pulse audio stuff"... It must be another way.
I want to record a streaming-audio (not capture), to use an alarm sound. I opened up gnome-sound-recorder, but I don't see input drop-down menu. I tried Audacity, but it's missing the menu, too.I saw the specification sheet of my laptop, but it only says Mobile Intel� GS45 Express Chipsets, I'm not sure if it manages sound, too, but the sheet doesn't have any information about sound chip set.dd: It seems like I can't change this to 'solved'. I cannot say it is solved, as I don't yet see the drop-down menu in gnome-sound-recorder, but with PulseAudio I can perform the task, so it can be regarded as solved?
View 1 Replies View RelatedI recently installed Ubuntu Natty on my Toshiba Satellite A210-139. Everything works fine except the microphone. I can hear a crackling sound also when I record using Sound Recorder, but it's not too bad. The big issue is with skype, where, besides an annoying, loud white noise, the receiver hears me quite intermittently. I tried many things. Firstly, I played around with Alsamixer and Pulseaudio with every possible combination. Didn't work. I also tried what seemed to solve the problem to many users: replacing
Code:
load-module module-udev-detect
with
Code:
load-module module-udev-detect tsched=0
in /etc/pulse/default.pa
I have been searching for an answer through most of the recent posts about sound issues but have not been able to find a solution. I am currently unable to capture sound from the "Line" input on my sound card. I do have sound and is working correctly for all applications and I do have P/A disabled (I'm not a huge fan of the sound quality with P/A enabled). I have checked and re-checked many settings but to no avail have not been able to capture sound. I'm sure I may be missing something or have not done something in order for this to work. I was using openSUSE 11.4 on a different pc and had no problems, unfortunately this is a different pc with a different sound card which is on-board so I am not entirely familiar with it yet.
It is a C-media CMI9880 which shows up as a Intel HDA (ICH6) and appears to be configured correctly.
Alright, just installed maverick, got the sound to work great on the 7.1 with pulseaudio. works great in movies, and everything else just wonderfully. the only thing i am stumped by is how to get the sound to loop from my digital input on my soundcard to my analog speakers also on the same soundcard. i know the sound feed works on the input as the makeshift VU meter/bar on my digital input in the sound preferences moves, but i can't get the sound to actually come through on my speakers.
View 1 Replies View RelatedI was just using the mic and watched it stop working suddenly. I was in the middle of a skype test call when the graphical mixer level died down to zero in the middle of the call. When the test call was played back, the first part sounded fine then the sound got lower until it became inaudible. Since then I can't get any sound from my mic in skype.
Also, the audio input level graphically shown in Sound Preferences shows no fluctuations in sound as it used to before. The input device is enabled. I tried using Sound Recorder to record some sound clips and that worked fine. So the mic is working but Sound Preferences and Skype seem to have the mic level really low. I'm not sure what else to think considering it was working perfectly a few minutes ago. I've tried restarting, but that didn't fix it either.
I am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).
