Ubuntu Multimedia :: Switch From Audio Input From Mic To Line On 9.10?
Feb 28, 2010
I wanted to take an audio feed from a stereo amplifier into my HP Pavilion DV6 laptop, in order to digitally record some old vinyl.
In the Sound Preferences tab, I seemed to be able to record easily from the internal mic, but there seemed to be no easy way to switch the preferences to enable recording from the Line In socket on the laptop.
We tried muting the mic, this only caused the system to record nothing. We also tried all the various available options in "the Hardware Profiles" tab, "Settings for the available device", but no the laptop seemed to be getting no "line in" input with whatever profile we tried.
On Mac, it was as simple as switching the input sound preferences from "internal mic" to "line in".

I'm using recordmydesktop for screencasts and currently use pavucontrol to select the monitor as the input source, as shown in many guides across the Internet, but I can't find anything on how to do it from the command line. How can I select a monitor as the audio input source for recordmydesktop from the command line?

I installed Lucid. I used to have Ubuntu 9.10 and to connect my iPod to my laptop's speakers. There was an option in 9.10 in the Sound Options to change the Mic Input into a Line Input. But now unfortunately I can't find it in Lucid have only 2 audio ports in the laptop: Headphone port, Mic port.

I am trying to record using a microphone without success. Checking my audio settings on the input tab all remains silent. I also checked the input channels using alsamixer and all looks correct.

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 have three jacks on the card, the usual with a normal home PC, - one for the speakers, second for the microphone, and third for line in. Now my speakers (Line out) jack is damaged a little. So when i plug in my speaker jack there, i get audio only in the right speaker (not a problem of the speakers, because i tested it, and not Ubuntu either, because this problem existed when i used to run Windows XP as well).
Now in Windows XP, what i used to do is, there was this tool (i think it came with the sound driver - Realtek) whenever i plugged in a jack into either of the sockets, a gui would ask me what i just plugged in, and it would allocate audio in and out according to what i specify then. So i used to plug in my speakers into the line in, because thats something i do not use, and used the tool to identify that jack as the line out.Is there some way i can do this on Ubuntu? i want to get line-out through the line-in socket. i'm a beginner with Ubuntu, and know only to use the GUI.

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.

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 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 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.

my computer is connected to my TV through HDMI using ATI HDMI output. I have written a small script to switch display from monitor to TV when a want to watch a DVD, but I didn't find how to switch sound from speakers to HDMI in command line. For the moment I have to open KDE system settings -> Multimedia and move sound devices by hand.

I'm using Mate on Jessie. The problem is that mate-volume-control kinda sucks as an audio control. It doesn't have nearly enough options for a proper volume control program. Pulse is much better for my needs. It or Alsa. Is it possible to remove mate-volume-control, or at least make Pulse the default volume control?

Does anyone know of any good command line audio editing tools? I would like one that can take an mp3 file and crop everything but the first 30 seconds or so (possibly decompressing those 30 seconds as well).

I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.
The error I am getting now is ./script.sh: line 6: [: : integer expression expected
Sample input $FileName

I recently got a real fancy unidirectional microphone, but when I go and use it, something strange happens. The mic is a mono mic, but when I record something, it appears to think it's stereo. Instead of having the same thing on both channels, it puts it all in the left channel, and silence on the right channel.
I tried fiddling with alsamixer. In capture (F4), adjusting the "Capture" device has an effect. However, it doesn't do anything useful. Lowering the right channel to zero does nothing, lowering the left channel to zero creates silence, and disabling the right channel creates silence.
In my System>Preferences>Sound (or pavucontrol, or what-have-you), there are "Analog Stereo Input" and "Analog Stereo Duplex" options there, but no "Analog Mono Input" or "Analog Stereo Output + Analog Mono Input" options (the latter being ideal).
Something interesting, though, if I do this:
Code:
arecord -r 96000 -D pulse -c 1 -vv -V mono /dev/null
it works correctly and outputs on both channels. But if I do
Code:
arecord -r 96000 -D pulse -c 2 -vv -V stereo /dev/null
then it's back to the same behavior. The VU meter on the second command shows the left channel going up and down as I make noise, but the right one always at zero.
The machine does have a crap internal mic built in to the screen bezel. If I do either of the above commands, they both work correctly. The stereo VU shows the same activity for both channels.
The machine is a Eee 1015PED, which has Intel integrated sound. Something probably insignificant is that the mic has a 1/4 inch mono plug, and to get it to plug into the Eee, I needed to get a 1/4 female to 1/8 male adapter. The mic's 1/4 plug is mono (duh) and therefore two-conductor, but the adapter I got is stereo, or three conductor (L, R, GND). I don't know if this is tripping something in hardware to tell it it's stereo or something.
I tried the mic on my desktop, which has a SB Audigy 4 (the non-pro flavor) and that has the "Analog Mono Input" function, so that works fine. Is there some way to turn this stereo input into mono input?

I have a file with two fields of numbers that I want to use as input for another program.
Code:
The above code does not work, as I think it would take the whole first and second fields as the input for one particular instance of the program 'inputbashangle'. What I want is to get the first two numbers from the first line of the file 'outfailtest', execute 'inputbashangle' with them, then move on to the first two numbers of the second line for all the lines of 'outfailtest'.

Since 13.37 I notice that vi needs the 'home' key to switch from input to command mode. I think this is only when I connect via Putty to the machine. When I am on local console it is still ESCape like it used to be. Does anyone know how to set it so that vi will switch from input to command mode using the ESCAPE key when using Putty?
Another vi question :
When you edit htm files, vi goes automagically into some sort of html display mode. Ofcourse I never want that since all I do is edit the html in vi. So I need to go to command mode and type :normal everytime I want to edit html files. Where can you configure that vi (or vim) default to normal mode always?
<I see that vi links to elvis : >
# ls -al /usr/bin/vi lrwxrwxrwx 1 root root 5 Oct 3 2009 /usr/bin/vi -> elvis*

10.04 doesn't support my father's computer. I always have to switch between 4.1 surround sound and 5.1. After I change a song, or watch another video, it only plays static, then I have to go into sound preferences and change it again, until the next song. I didn't have this trouble in 9.04 on his computer. The problem now is, he actually replaced windows with Ubuntu this time, so he wants everything to work. So what software was installed in 9.04 and how do I get it to 10.04?

I've an older PC, and I would like to use it with Lubuntu, because it's much faster than Ubuntu or Win XP (excuse me for the comparison). The only thing that prevents me from using Lubuntu is that I can't find any application to switch the sound card!
How can I switch audio devices from Lubuntu?

For some reason on any application that uses sound, but doesn't allow me to specify the input/output audio devices I don't get anything. I want all audio to go to my USB Headset, and not the onboard soundcard. To start off with, here's alsamixer: Here's a screenshot from Mumble (voice chat) that shows that I've set the USB headset device in there, and it works 100% fine on Mumble.
[Code]...
As you can see from the alsa-base.conf above I've tried specifying snd_usb_audio as the default device, but it's not working.

I am using Ubuntu (Studio) 10.04 (kernel name reads "2.6.32-25-preempt"), and I am having a problem with applications that send audio over network connections (skype, google voice, etc.)- the audio that comes out on the other line sounds like small periodic blips. I figure this must be some kind of clocking mismatch or something?
- I can record audio just fine using audacity or other recording interfaces.
- All forms of audio output, including skype and google voice, work just fine (I can hear the person on the other line, but they can't hear me).
How to adjust whatever settings I need to make this work?
Here is my soundcard from lshw:
And my network interface:

On karmic the audio input device would constantly reset to muted. On lucid, it keeps resetting it to the microphone jack at the back of the computer (While I have a webcam up and running that it knows is what I use. How can I get it to remember my audio input? One more functionality issue till bingo. How can I give a window "Widget" status: I want it not to minimize when I hit ctrl alt D (Like conky and other widgets).

I use a Logitech USB headset with microphone at work for phone conferencing, and for some reason whenever I restart Ubuntu (and sometimes seemingly at random times), the settings for the audio input device revert to the defaults (the internal audio hardware).I can always reset it back to the USB headset by going to the sound configuration menu (Preferences -> Sound -> Input), but if any applications that use a microphone are already running, they will need to be restarted in order to make use of the newly configured input device.

I need to set the default input device to be the microphone on my webcam for when I skype, but it seems to keep resetting itself, so I keep going in and changing it.
I am right clicking the volume icon and going into Sound Prefs -> Input, and selecting the camera.
How do I stop it from forgetting this and resetting it?
