General :: Debug Program And Need Something Like A Virtual Microphone?
Feb 13, 2011
I need debug my program and I need something like a virtual microphone. I would like device "microphone" where I can put sound file and this file will be input for microphone stream. And in application I get this stream from this "microphone"
File -> Microphone -> Application
is it possible?
something like bash command should by very very useful:
aplay --device=mic my_microphone.wav to run a microphone stream
I"m running an online radio station and would like to run my headphone audio into my microphone or a virtual microphone, either way, I would like my audience to hear what I hear without having to hold the Mic to the speakers.
I want to allow my program to be able to run in DEBUG mode. i.e., I want to be able to run ./program, and I want to be able to run ./program -v to show all the debug output. How do I go about setting up something like that?
I need a simple program that I can talk into a microphone and the sound will come out the speakers. I want to use my Computer that's hooked up to the store speakers as a PA System.
I am having a difficult time finding a program that will let me do this without having to record and playback. Any help would be wonderful.
I am a new ubuntu user but I used linux mint before ubuntu and I had the same problem there. My microphone only works when 1 program is running, but if I load a game or something my microphone stops working.
i want to install a program called VMPK its a virtual keyboard, but through googling i seem to keep running in circles. The program comes as a tarball, which i have no idea how to install (still semi new to Linux... within my first 2 months)... i have read something about compiling it as an RPM but i cant seem to find anything else other than that... this is probably something super simple
I was running 9.04 and could, through some magical sequence of toggling options that I was unable to figure out, occasionally get recording from the mic to work in audacity. Ardour worked more reliably, but is kind of over-featured. Audacity is simpler and I know how to get things done. For a while, I was doing basic recording in Ardour, saving it to wav then editing in audacity.
Well, I noticed a howto on getting audacity working in 9.10... so I upgraded ("what could possibly go wrong?"). I still can't record audio in audacity and ardour is now ALSO unable to record audio. They start recording samples but nothing comes in but silence. I've got audacity set to ALSA/default/default and when I click monitor, the stream appears in the pavucontrol app. I've moved it to the input device and that doesn't seem to affect the results at all. Everything looks like it should be working fine except there's some invisible mute button, or something. Under alsamixer's Capture section, Mic has a red "CAPTUR" with no bar to adjust.
I am looking for a DJ program to use with this OS. I am look for a program like virtual dj to use that will play mp3's. I have seen some programs that will play music, not able to find a song as I have 1,000's of them. So far I have seen ubuntu looks very promising.
vlock works, however it requires that I return to the shell to run it. Is there a way to assign a key combination to run vlock, so the current program doesn't have to be ended?
I am compiling gstreamer for my ARM board. When i compile that i am not getting "debug" messages. so i want "debug messages" while make my gstreamer. i added "./configure --enable-debug" but still i not getting debug message while i "make".
/var/log/debug gets lots of messages any time an LVM snapshot is setup (lvcreate --size ${size}k --snapshot --name "$LVM_snapshot_device" "$LVM_device"). Here is a recent sample.
Code: Feb 19 22:40:10 CW8 lvm[2163]: Loading config file: /etc/lvm/lvm.conf Feb 19 22:40:10 CW8 lvm[2163]: Opened /etc/lvm/lvm.conf RO
I am trying to debug ssh permissions and keys. I am able to connect as root. However, I am unable to login as a new user (e.g., newuser). I have been trying to ssh as localhost to debug the issue. For example:
>ssh -vvvv newuser@localhost
will yield a lot of information. I think this is the relevant section, however, I am unable to resolve:
debug1: Host 'localhost' is known and matches the RSA host key. debug1: Found key in /root/.ssh/known_hosts:2 debug2: bits set: 533/1024
I would like to configure and SAN disk. But I do not have a physical SAN disk. Is it possible to create and configure a Virtual SAN disk and work on it with virtual machines?I have around 400GB of space in my Laptop.
Ive been messing around on a Solaris box, installing precompiled lib/programs from the repos by extracting them and placing them in my home dir. It seems everything ive tried sofar works, except for irssi. I get the following error:
$ ~/bin/irssi ld.so.1: irssi: fatal: relocation error: file /export/home0/leem2/bin/irssi: symbol boot_DynaLoader: referenced symbol not found Killed
I have run: $ ldd /export/home0/leem2/bin/irssi and it has no missing libs
Does anyone know if it is possible to make rules in a Makefile that would work like this:
> make debug module or > make module debug
where module can be any module that has a specific rule in the Makefile.
The thing I have is a Makefile with different rules that I compile like this:
> make module
What I would like is to add an option so I can compile whichever module with debug-information just by adding a debug to the make command. The debug-information I know how to do, the problem is how to make the Makefile work...
I have a working build of crosstool - it was built for gcc 3.4.3 using glibc 2.3.5 going from 32-bit x86 linux to 64-bit alpha linux. As far as I can tell -- it compiles correctly (output of alpha emulation matches expected) but it has a major flaw. When I use the cross compiler and attempt to add detailed debug information, it compiles, but does not have the debug information. For example, when I execute:
/home/leporter/crosstool/gcc-3.4.3-glibc-2.3.5/alpha-unknown-linux-gnu/bin/alpha-unknown-linux-gnu-objdump: hello: no recognized debugging information
Frustratingly - if I use my x86 gcc version 3.4.6 to do the compilation (same arguments, just using the x86 compiler, not the cross compiler) - it correctly embeds the debug information.
I have problems with my USB driver. After adding my device (MSP430 USB-DEBUG-INTERFACE) it doesn't work.

if anyone can send me in the proper direction for this question, I would be grateful. I installed the newest Linux mint on the newest version of virtual box. I'm have trouble with program "giver" recognizing the virtual machines. I'm not sure if it has to do with the fact that, its using my mac's ip addresses or not. i have 2 other Linux mints installed on two other pc's on the same local network, and they recognize each other just fine. so my question is, does a virtual machine have to have its own ip address for program "giver" to recognize each other? maybe i have to change the network driver on vbox, but every time i do, i lose connection. at the moment, my network driver is set to NAT.
I've been using this howto to set up automatic logins to virtual console using "a C login program" method. In slackware64-current updated till january it prompted me to enter a password before logging in, while now after installing latest updates and kde 4.3.5 from current it logs in automatically without any prompting.
