Ubuntu Multimedia :: Sound Output Redirects To Input
Jun 9, 2011
For 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.
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.
When I installed my 64 bit system of Ubuntu 10.04 the sound worked very well and I were very happy. The problem started however when I installed Skype which uses pulseaudio. As soon as I start skype (or any other application that uses pulse, HoN for example) the applications sound output or input does not work at all. If I have pulseaudio started in some way, applications that I suppose do not use it like spotify or flash player stops to produce sounds. And when I type "pulseaudio" in the terminal it gives me this:
I want to compare the quality of a sound file (voice) before and after its transmission via a softphone (sjphone in my case). For this, i need to redirect the sound played, to the sound input (microphone or line-in).
I cant seem to install Ubuntu 9.10 at all. At 15% I get the following Error Message Input/output Error During Read On/dev/sda then I get the creation of swapspace in partition #5 of SCSI1(0,0,0) (SDA) Failed. Ive tried 6 times already. Im getting no sound at all. How can I change the screen resolution. 800 x 600 is the highest it will go. Im getting really discouraged with Ubuntu. Alot of people seem to have the same problems I am having but there is no solutions. I've checked the MEMTEST and passed, done a disk check and passed.
Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.
I am attempting to connect a bluetooth headset to a Telex Intercom System. I can connect my bluetooth headset to Ubuntu and use the microphone and the speaker perfectly. There are no problems with the Line-In or the Line-Out.
Is there any way to connect the BT-Microphone to the Line-Out while connecting the Line-In to the BT-Speaker?
I use the growisofs command from the terminal to do most of my burning. Mostly because i burn almost the exact same type of file every time so its pretty easy to set up. I've done this dozens of times and never once had a problem before. I loved it because it was so much simpler than doing this in windows where i would need to install a few extra programs and codecs. That was up until today where it started failing every single time i tried to burn something.
For some reason every time i try to burn a disc it gives me this error message:
Code:
I'm really at a loss as to why this is happening. Every thread i found that discussed this problem was mostly focused on k3b or brasero and never really answered the question. As far as i know nothing has been updated since the last time i burned a disc a few days ago. Everything is exactly the same as it was when it worked. The only thing i could think of that might have caused this sudden failure is that i flashed the firmware of another cd drive using the same sata port that this drive is currently plugged into, but that was in windows so i dont see how it could have affected this drive.
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 am currently trying to start doing some screen casting and having a problem with audio recording in gtk-recordmydesktop. The problem is that I need to record both; my computers audio card output, and my mic input at the same time. As of now I am able to record one or the other.
I'm trying to create an iso file in a terminal with the following command: $cat /dev/sr0 > nameofdisk.iso I get the following error cat: /dev/sr0: Input/output error I already checked and my optical drive is indeed /dev/sr0. I've hunted google a few hours trying to figure it out. Does anyone know why I'd be getting this error?
I 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.
I am using a USB headset and a logitech QuickCam Pro 4000 with Ubuntu 10.04
1. When I change the sound to internal sound the webcam works in Skype but I have not sound. 2. When I change the sound to the USB headset (sound output) the webcam does not work in Skype.
I have a TV card connected to my Dish box, and I would like to use it on my computer. The tv card works fine, and the audio is connected to my line in. The audio card receives the audio signal, and I can set the volume and record it without any problem, but I can't get it to redirect to an output in order to hear the sound. I have been battling with this issue since a kernel update back when 11.2 was about to come out. Back then, the alsa mixer had an option called audio loop-back, which did the trick. Since I know I ca record the audio and play it back without any problem, is there an application that can do this automatically and simultaneously?
I have a headset microphone plugged into the built-in audio input. The output is plugged into an amplifier > speakers.
Pulseaudio is "helpfully" routing the microphone input signal to the speaker output. I do not want this. I go to pavucontrol and disable the "monitor of the internal audio analog stereo" -- and what I say into the microphone is still coming out of the speakers.
Google gives a lot of information about how to live-stream mic input over the Internet. And, I found this here (that's for karmic, I'm running lucid):
[URL]
... but that's about how to ENABLE loopback. It says loopback should not be enabled by default, but I very clearly hear that something is doing the same thing as loopback.
(Of course, I need to hear sound from applications that are playing, and when I'm dictating text into NaturallySpeaking running under virtual box, I need sound input to go there -- so turning the mic all the way down to zero is not the solution.)
I'm fairly sure I remember hearing this behavior ever since installing Ubuntu, and I didn't do anything to turn it on. I can't imagine most users would prefer this behavior -- if it's the default behavior, why? It makes absolutely no sense to me. (Sorry. It's one of those piddly little configuration things that costs a couple of hours of web searching time, and after a while I just have to give up, but not before becoming much more frustrated than I should have to.)
So, to be clear, here's what I want:
- Applications playing audio should send sound to the main output.
- Applications receiving audio input should hear the microphone.
- Microphone sound should not EVER go to the main output unless I have explicitly launched an application making the connection. (The signal goes input -> output even when NO application is open - hence my consternation.)
I'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.
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.
When i try to record with my dvc100 on Ubuntu the only thing that i found works is vlc but that doesn't even work properly. i found out that vlc-plugin-pulse is flickering on and off can i either replace or fix this.
I 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?
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.
In 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 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.
