I am fed up of listening to my (Windows XP) gaming computer through headphones so I want to get it hooked to the stereo.
Rather than use a heck of a lot of wire, I can sit my Ubuntu 9.10 netbook on top of the stereo and stream the audio across WiFi.
So, ideally what I am after is something to capture the outgoing audio on the Windows computer, stream it across the wifi to the Ubuntu netbook and finally play it through the speakers.
I am trying to resolve an ongoing fight involving /dev/video node assignment between 2 TV Tuner cards and a USB video camera.
Each time I reboot the three devices seem to shuffle their /dev/video assignment. i.e. what was /dev/video0 (USB camera) after a reboot magically becomes /dev/video1.
This causes all kinds of grief between my MythBackend and ZoneMinder who expect the devices to have static assignments.
how to best solve this? I did a brief search and one solution appears to be to statically assign the devices.
Say I have 2 speakers connected to 2 different sound cards. Under Windows, is it possible to have some sort of virtual device that would forward an audio stream to both sound cards? If this can't be easily done under Windows, a solution for Linux is also fine. lternatively, if the 2 speakers are connected to different channels of a sound card, is there any vendor-independent way to duplicate audio to both channels?
View 1 Replies View RelatedI just installed Maverick on an Asus Seashell 1215T netbook with an AMD/ATI chipset. The sound output is working fine (with the exception that I have to manually set output to either speakers or headphones rather than just plugging in headphones), but neither the internal microphone nor external microphones plugged in through the mic jack work. I do have the sound device set to the internal sound (rather than HDMI) and the volume level set appropriately. Apparently neither microphone is being recognized. Any ideas on what could be wrong?Here is the relevant section from lspci -v:

View 3 Replies View RelatedMy local priest has asked me if I can use my computer skills to stream church services live for people who can't make it to church.I said, sure thing! I thought it would be simple, but the deeper I look into it, the more lost I have become!Here's the tech requirements:
- A camera with good optical zoom and focused on the altar (the camera will be stationed at an unobtrusive point at the back of the church on the choir balcony)
- Everything must be wireless (power is available on choir balcony to power the camera).
- Sound should be synchronised perfectly with the video (have access to the church PA system - located behind altar)
- the internet connection should be able to upload the stream to a virtual server (i.e. with root access) that's accessible to the web with ease. What upload speed would I need? Would 256k be enough? HD video is not required - ..... quality would be great. We can upgrade to HD at a later point in time!
- What bandwidth requirement would my server need if say 1000 users were connected? Seeing as they would most likely be locals, would just one stream be sent to the local exchange and that exchange would send out the stream to the 1,000 users, or would each user have to have a dedicated connection to the server?
- Say I bought a camcorder with HDMI output, what kind of processing power would I need to convert this to compressed video? (I've got an old Pentium 4 and an AMD64 2.0GHz lying idle in my bedroom and it would be great to make use of 'em instead of chucking 'em on the skip)
- I'd like all this to be done so that HTML5 browsers can access the video, resorting to flash if necessary
- I'd also like to be able to power down all the hardware with ease: i.e. set a timer. I'm sure ubuntu can do this with ease? What about configuring the camera to zoom in every time it is powered on? Can linux control the zoom on a camcorder?
- Am I totally nuts?
I am trying to record audio playback from an application and the microphone at the same time on recordmydesktop using pulse audio. I just can't figure out how to mix them both. I have tried a lot already and can only get either the mic or the audio playback to be recorded, not both. Can this be done using pavucontroll?
I have been search now for hours to find a solution (also here on the forum) for this and getting really frustrated now. Maybe i'm just missing something really obvious, so sorry if this is a stupid question.
Is it possible to pipe audio from espeak into a microphone device?
I've tried doing

I use F-spot and Shotwell to extract photos AND videos that I made with my Canon EOS 500 or my Lumix.Actually the pics are extracted correcly but the videos are just consider as a pic and the pic is the first pic of the video.Is there any F-spot equivalent that extract everything from the camera?
View 3 Replies View Relatedhow can I adjust the volume level while recording audio playback and microphone at the same time? I managed to increase the audio playback volume with PulseAudio Volume Control (Input devices -> Monitor of Internal Audio Analog Stereo -> pressing green button "Set as fallback"), but once I click on that green button, no no microphone sound is recorded.

- using Ubuntu 10.04 LTS
- recording audio with Sound Recorder
- installed PulseAudio Device Choooser and PulseAudio Volume Control
- Input devices -> Internal Audio Analog Stereo --> shows the sound from microphone

- how to adjust volume of audioplayback and microphone recording and record both as a mix together? Thanks!
PS: I checked out this thread, but haven't figured out how to adjust the volumes.
First off, this isn't the usual "physical" feedback of a speaker being too close to the mic. This mic is part of a headset so there's no way for the output and input to overlap and cause feedback. This mic has worked perfectly for me in the past, but I recently re-installed my OS and it hasn't worked since.
It seems as if my audio out is getting redirected to microphone in. If I open up and sound recording program while I have some audio being output, the output will get echoed back in through the microphone channel, although any actual microphone input is never picked up. I can blow or scream into the mic and there's no indication at all that Linux is picking it up.
I'm running ArchLinux with ALSA. I've gone into alsa mixer and played with just about every channel in every way I can think of, and none of the options seem to fix the problem.
How should I fix this? I use my mic pretty much constantly when I'm on the computer, being without it sucks.
I currently have eight surveillance cameras setup that used to connect to a windows pc. I decided to throw away the old computer, take the dvr card from the old computer and use it in a new computer with ubuntu 9.10. However, till now I can't get the cameras to work.
I installed Zoneminder, and followed instructions from here and there with no useful results. What I currently have are monitors showing black screens, with the fps showing.
I am pretty much still a noob, so I am not sure where I went wrong. I do not get anything when i run XawTV (or maybe i don't know how to run it right).
when i run "lspci | grep Bt878" I get this

Following instructions from various places, this is what I have for the following files /etc/modules :

I followed the instructions for installing Zoneminder on Ubuntu 9.10: [url]
I also get some tips for setting up the tv card: [url]
What is confusing is I get a fps rate, which is a sign that the camera is working, but all i get is a black screen. The cameras used to work in the original windows setup, so i doubt that the cameras are not working.
I have a video file in which the audio runs faster than the video, so they quickly go out of sync. The way to fix it would be to separate the audio and video streams, speed up the video (the audio is FINE, it's the video that's wrong), and then recombining them. What is the easiest way for doing that?
View 7 Replies View RelatedIs there an application that anyone knows about that I can use to convert either an .flv or .ogg file that contains both audio and video to just an audio .ogg file (preferably vorbis+theora) without audacity? I'm fairly certain audacity could accomplish this but it seems like overkill for what I'm trying to do and the computer I'm trying to use does not run it so well.
::EDIT:: I should also mention that I've tried looking on google. I did find downloadhelper extension for firefox which uses ffmpeg to convert the files but I don't see any obvious way to strip the video.
I have some microphone problems. I can't record anything. (I'm using openSUSE 11.3)
My sound card was detected almost correctly (at least the chip-set was i think). I have an Asrock motherboard (k7upgrade880, with a Southbridge: VIA 8237 | Audio: CMedia CMI9761 6 channel AC'97.
I ran these commands so far with these results - while i was following the audio troubleshooting guide (SDB:Audio troubleshooting - openSUSE
But i have NO audio playback problems - movies, games, music all play well. And the Microphone guid has a broken link
I tried to change my 50-sound.conf file (i read it on a forum, I'm new to linux troubleshooting) from this:
options snd slots=snd-via82xx to this: options snd slots=snd-via82xx position_fix=1
But that did not work either. I did not get any sound with the last line.
i just upgraded from Skype 2.0.0.72 to 2.1.047. Now my microphone isn't working anymore and i cannot select it in the skype options. From now on i can only select the PulseAudio server ..
So i have read some howtos for PulseAudio. They say i should starte PulseAudio Volume Control. ok.. Now i should go to the tab "Recording". This tab doesnt exist on my pc. I upgraded to the latest version of this volume control. It still doesnt exist.
I am using OpenSuse 11.0 with KDE4.3
Here are some screenshots:

We've bought a cheap video camera for our son to make a movie. Files are stored on a 16Gb SD disk. When we first used it a week ago I was able to connect the camera via USB and copy the files to my laptop. Today I went to clear some more files to make room for shooting the movie and nothing shows up when the camera is attached to the laptop. I can view the files on the camera so they do exist.
I have tried:Using different usb ports Using a different computer Using an SD Card Reader on both computers Investigating permissions via terminal (the camera seems to be set to RWX Checking that no one has played with the settings on the camera Nothing has changed on the camera or the laptop as far as I can see and yet the files are not showing up.
Camera Model: HD-C2 2.7" LCD 12MP
