I was wondering if there is an application for Ubuntu (FOSS or otherwise) that would allow me real time management of all of my audio inputs and outputs. Essentially I have multiple microphones attached to my computer and multiple audio outputs. What I am looking to do is to be able to assign each different input to it's own audio output. A touch screen interface is a plus for the program but not necessary.
View 9 RepliesWith pulseaudio handling sound on Lucid (10.04), when I plug in my USB headset it's recognized, but there was no easy way to have it be used without going to System > Preferences > Sound > Input & Output and checking the radio buttons. Then if it's unplugged, and plugged in again later, the setting has been lost, so it was back through the menus. Not good when the headset's not plugged in and I'm fumbling to answer a Skype call. What would be ideal is if pulseaudio could prioritize and always default to the headset when it's plugged in. But I'm told by one of the pulseaudio gods (Col) that it can't yet.Here's a way to at least get the switch down to one button on the panel bar.0. Get all your devices plugged in1. Find your outputs (speakers, headphones):Quote:pacmd list-sinks | grep alsa_output2. Find your inputs (such as a microphone):Quote:pacmd list-sources | grep alsa_input3. Write a bash file to choose one or both, like this but with device names appropriate to your system which you've discovered above for the alsa_output.* and alsa_input.* strings.Quote:
#! /bin/bash
pacmd set-default-sink alsa_output.usb-Generic_FREETALK_Everyman_0000000001-00-Everyman.analog-stereo
pacmd set-default-source alsa_input.usb-Generic_FREETALK_Everyman_0000000001-00-Everyman.analog-stereo

I'm using a fedora install mainly for audio work and have everything working well out of the box. My setup is simple:
-Direct cable from Guitar 1/4" > Sound Card input>Rakarrack Guitar Effects>Ardour>System Out
(Occasionally I put a synth/plugin like Zynaddsubfx or jackrack before or after rakarrack depending on what sound I'm going for)
-Jack for all audio transport with synthesizers
I have real time support with Jack and all other programs except Rakarrack. When I launch Rakarrack in the terminal, I get this message:
Code:
rakarrack 0.6.1 - Copyright (c) Josep Andreu - Ryan Billing - Douglas McClendon - Arnout Engelen
Try 'rakarrack --help' for command-line options.
Cannot lock down memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/15)(1: Operation not permitted)
AcquireRealTime error
However, running rakarrack in root does not display this output, and I assume it has no problem getting real-time scheduling in that case. I did some google searches but the only similar issues that I find are that people can't get RT support in jack except in my instance, I do have RT scheduling with jack, but for some reason I can't get it in rakarrack unless I'm root.
[Edit] I actually have to run jackd and rakarrack in root to get rakarrack to use real time scheduling. But, it isn't necessary for any other jack compatible program that I know of. I'm actually not getting any real time scheduling with any jack application, even though Jack is reporting to be running in Real Time. However, running everything in root fixes the issue even though I would prefer to not have to run as root.
i am not sure if this hardware section is the proper place to put this question but my problem is like this. I want to record headphone mic input in a local file every time my system boots up and broadcast the real-time audio or rather multicast it through local LAN

View 1 Replies View Relatedboth audio inputs (I use the integrated mic on my notebook) and jack-sense (integrated speakers/headphones) work properly, as they should. But after some time (from few minutes up to several hours) both of them cease to work simultaneously. After that the mic input levels turning gray and speakers don't work at all (when headphones were connected at that moment) or speakers don't mute when I connect my headphones (if headphones were not connected then). After I reboot, everything is okay again for some time, but then it happens again. Setting mixer levels manually with alsamixer doesn't help at all. I also tried different snd-hda-intel model settings in alsa.conf, but that just made things messed up, so I stayed with auto setting. This way everything (inputs/outputs/sense) works as should until it simply stops working.
It's maverick, ALC268, ATI Azalia (Intel HDA), alsa 1.0.23, but I had this problem with karmic and lucid as well when I tried them. Now I want to switch from Win7, but this is the only thing keeping me from it.
I installed Ubuntu with the netboot. I only installed the packages I needed. Concerning X, I installed xdm as login manager and fluxbox as window manager. All is working fine except that whatever I type under X (under xdm or, after logging in, under fluxbox) appears in tty1! The keyboard inputs appear under X and under tty1 (so usually after "login:", or hidden after "password:").
Let me provide you with more details. Starting from xdm, I cannot access to the other ttys. "ctrl+alt+F[1-6]" do not work. Actually, this is not entirely true: after I type "ctrl+alt+F2", all my keyboard inputs under X will be appear in tty2 (and not anymore in tty1). I can see that from /var/log/auth.log which has a lot of lines like this:
Quote:
May 13 10:15:45 data login[2182]: pam_unix(login:auth): check pass; user unknown
May 13 10:15:45 data login[2182]: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost=
May 13 10:15:48 data login[2182]: FAILED LOGIN (2) on '/dev/tty1' FOR 'UNKNOWN', Authentication failure
These errors are due to the fact that tty1 receives a wrong login (something I typed under X, before pressing RET). BTW: If I connect to xdm using my password (instead of my passphrase, thanks to pam_ssh), then I login into tty1 at the same time.
I checked that X is running under tty7. "ck-list-sessions" returns:
Quote:
Session1:
(...)
x11-display = ':0'
x11-display-device = '/dev/tty7'
display-device = ''
remote-host-name = ''
is-local = TRUE
(...)
Under X, if I type "ctrl+alt+F7" and "RET", then X crashes and it is launched again. After this, all is working fine: the tty[1-6] can be accessed and the keyboard inputs do not go anymore to them when I am under X.
I face the same problem on two different computers (a desktop computer and a laptop). Notice that I face the problem even with pam_ssh not installed (I mentioned pam_ssh earlier).
I've searched high and low, and can't seem to find a solution to this. I'm running a Dell Inspiron with an HDMI output with 10.10 through the tv. I want to get HDMI sound output for VLC, but I also want S/PDIF output (to the stereo) for Musicplayer. I can test and use the HDMI in the sound preferences sound/preferences/sound, but when I try to do the same for the internal card and click 'test speakers' the sound program closes itself. When the machine was a windows machine, it had PowerDVD outputting to the TV and Mediaplayer outputting to the stereo. I'm aiming for a similar set up in Ubuntu.

MPlayer 1.0rc2-4.1.2.
I have a .avi file on the hard (really on a cd-rom, but it's just the same). Being in the GUI (KDE), I do Main Menu>Run Command and then, in the dialog box, I enter 'gmplayer foo.avi'. Gmplayer starts, the picture of a small console is seen on the screen, and the audio from the movie is heard. Just as if I had inserted the CD into a stand alone dvd player but I could not see the image. I compiled and installed mplayer (with GUI support) from the slackbuilds.org sources and script for slackware 12.0, which is the slack version installed in my machine. If I open a terminal (in the GUI) and run gmplayer there I get this:
Code:
VIDEOOUT: [VO_XV] It seems there is no Xvideo support for your video card available.
[VO_XV] Run 'xvinfo' to verify its Xv support and read

[VO_XV] Try -vo x11.
CPLAYER: Error opening/initializing the selected video_out (-vo) device.
I know I could do what is suggested by gmplayer but, before that, perhaps I am simply invoking gmplayer in the wrong way. That is: there are at least to ways: using the Run Command dialog box and opening a terminal and running as a cli command.

I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.

View 3 Replies View RelatedI have a linux router box with ubuntu which routes internet for several people. There is no extra traffic shaping, so everybody can get the whole bandwidth when its free. What I would like to have is a real time traffic counter per ip, just like a program called "iptraf" but on a per-ip basis. Iptraf can only count on a per-connection basis and thus cannot display a bandwidth that a certain ip has taken (because a single ip can start several onnections). So a console program with text interface like iptraf would be perfect - does anybody know about such a program? After some googling I came to the conclusion that such a program does not exist (which must be wrong - i think that per-ip real time traffic flow information is the first thing every router owner would like to know).
