Ubuntu Multimedia :: Input But No Output On Firewire Device?
Jun 11, 2011
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'm trying to view the output of a dv firewire capture device (advc-100) fullscreen through vlc. I've read of people being able to do this but a detailed explanation of how eludes me.
I'm running Ubuntu 10.10 and VLC 1.1.4
The error message I'm given after trying to open through 'media>open capture device>play' is;
Quote:
Your input can't be opened: VLC is unable to open the MRL 'v4l2:///dev/ffc1/'. Check the log for details.
(and I can't find the log)
I'm not even sure if I've got the device name right so I ran lspci from the command line which gave the following output (and I still can't work out what it is);
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.
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.
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 use a USB webcam with a built in microphone. It works fine, but every time I plug it in I have to go to sound properties and select it as the input device. There are no other input devices present on my system. Since it's the only one there, is there any way to get it to automatically select when I plug it in? If not, I think that would be good functionality to add. Does anyone know who or what team to contact about that?
No audio input device can be found in sound preference>input but in sound preference>hardware>it shows the input webcam recorder device.
When I use
Code: alsamixer
onto terminal it shows this
and also i checked cable device and everything. And it was working till I last hour. I rebooted computer then there's some problem, I haven't change anything before or after rebooting.
I can't use my line-in/microphone jack. In system-management-sound input tab there is no input device listed, and the input controls are grayed-out. sudo lshw -C sound produced:

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'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 using a sound card with the C-media CMI8788 chip. This card has both analog and digital outputs, which Linux sees as two different output devices.
The Problem I am having with VLC is that it always changes the output device in its settings to analog. I constantly have to be going into VLC advanced settings and picking Alsa: Digital for the output.
After that the sound outputs fine.
This only happens with VLC. All other programs on my pc output sound perfectly fine. I am using Lucid.
How can I set the default to be the digital output?
I have a FireWire camera LifeSize connected to my PC in the FireWire interface. My PC has miniPCI slot and with external converter its having a FireWire interface. Now its Ubuntu who is not showing me anything at all when i try:
$ uname -a Linux desktop 2.6.38-11-generic-pae #48-Ubuntu SMP Fri Jul 29 20:51:21 UTC 2011 i686 i686 i386 GNU/Linux
I just setup a FireWire audio interface. Everything works fine, except for I need rw-rw-rw- permissions on /dev/fw0. I can always sudo chmod 666 /dev/fw0 just before setting the thing up, but then it will be gone on the next rebooting.The solution to modify /etc/udev/rules.d/020-permissions.rules (which is for Ubuntu Breezy) doesn't go well for Ubuntu 10.10 Maverick because there is no /etc/udev/rules.d directory.
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 am working on an embedded system, which is an USB MSC device that supports some vendor specific scsi commands. I am using FC10 laptop as USB host for testing, and it runs some small apps based on sg3. All has been well for ~ a week. The FC10 laptop is able to communicate with the device and retrieve data. Suddenly, starting from today, the laptop is not able to properly detect the device. When plugged-in, the MSC device is detected as input device (I thought). This is observed from "dmesg" output and changes in "/dev/input/".The device under development is running at full speed. When I connect to winXP, no problem. A windows file explorer pops up, showing the content of the drive.Also, the FC10 has no problem with other USB flash drive (high speed).
I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone
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 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 want to capture DV-video through IEE1394 (FireWire) with Kino and Ubuntu 10.10. Seems I can't capture... When I plug in the camera there is no hot plug message (if there should be one? I've read it should...). The DV-out on the camera is enabled There is no option to enable/disable the port in my BIOS.
Some information: Code: a~# lspci | grep 1394 07:09.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05) Hope there are some command to check?
I bought a USB to firewire cable to use with a DV camera, but I don't know what to do now. Do I need to enable firewire drivers, or is there something else I should do? I know I should read the manual.
