Here's what I a running dell n series Inspiron 910 ubuntu hardy heron the following codes read :

Is it possible to output one playback stream to multiple devices simultaneously with the current PulseAudio / Phonon setup? The PulseAudio mixer only has radio buttons to choose one device per playback stream. I believe the hardware is capable of this, since I remember doing that before we had PulseAudio. How can I duplicate an audio stream?
Here's one application scenario: I am travelling with my family, all crammed in small hotel room. My wife and me want to watch a movie on my laptop without waking up our kids. I just happen to have one analogue headphone available and one wireless USB headset with me. (Of course, the low tech solution is to bring an 3,5mm Y-cable to attach two analogue headsets, but I would really love to use the USB headset together with the analogue one.)
Another similar thing that bugs me is that my laptop's built-in speakers now always seem dead when an analogue headphone is plugged in. This is mostly what one wants, and before PulseAudio, one had to manually switch them off which was generally annoying. However, the downside is for example with notifications.
For example, before PulseAudio, I could configure Skype to always ring over the laptop's built-in speakers, regardless of whether the analogue headphones were plugged in. This is no longer possible, since PulseAudio does not distinguish between built-in speakers and built-in analogue port any more, while old Alsa did. So in my office, where some analogue headphones are plugged into the docking station, I never hear Skype ringing if I don't wear the headphones.
I get ubuntu 10.04 LTS installed on my PC and laptop , and I tried ubuntu one.It worked and I want to have a test, so I removed the two devices that already subscribed to my ubuntu one account, after that, I found I can't get them subscribed back.Everytime I start ubuntu one preference , I'll get the error message: got empty result for devices list.How can I add my two devices back to my ubuntu one account (I googled a lot and found that someone pointed that delete the ubuntu one's key will work, so if this is the right solution, how to delete it?
Is there a terminal command or application to browse attached firewire devices in the likes of lspci and lsusb? I'd like to view elementary device information such as the ID, manufacturer, and the like.
I would like to ping all my virtual hosts in virtual machine server with a oneliner. For example like this:
Code:
for i in $(seq 1 20); do if [[ $(ping host$i.virtualhostserver.com -c 2 2>/dev/null | grep "2 received") == "2 packets transmitted" ]]; then echo $i; fi; done
The problem is, that I'm afraid my if-sentence is somewhat wrong because it never gets a match even if I know, that host is up.
This is probably me looking but not seeing an option somewhere. I re-installed 10.10 over 10.04 by formatting the root partition but keeping the home partition the same, to save me a lot of work. (64 bit) However, now when I mount a CD, DVD or USB stick, they don't appear in Dophin's "Places" window. What have I missed please?
I would like to display hardware devices and their drivers in Debian. Sth similar to windows 'Device Manager' not necessarily must be in gui version. What kind of cmds I should use to be able to display hardware detected by HAL and their drivers ?
As the title says the machine name is not showing up in the attached devices list on my router. Is there a file where I need to add the name? Or is this an issue with the router? The router finds all the other machine names on the network except my 3 servers.
I want to know that is there any command by which i can check which type of hardware devices are installed in my Linux box like SVGA,Sound Card,LAN Card.
I have been administering linux systems for years now, but usually they are commodity boxes and as a result I rarely have driver problems, short of needing to install some "restricted" or "proprietary" driver package, or manually installing the nvidia binary drivers back in the day. However, one question to which I have never picked up a straight answer regards common troubleshooting practice. Will lsusb and lspci list device for which a system has no drivers (kernel modules)? I am trying to install a webcam on a SiS-chipset laptop and though I can see a physical webcam, neither lsusb or lspci are showing me that any webcam-like device exists. What I want to know is if it would show anything, or if it needs drivers in order to show a device?
I am using debian squeeze and did an aptitude upgrade yesterday. Today I've found that VLC won't play any video; the files open and the audio plays, but the video is black. The aptitude log is below.
I note that VLC received a security upgrade a few days ago, but my suspicion is that the source of this problem is more likely to be the upgrade of libavcodec52 from version 4:0.5.2.6 -> 5:0.6.1+svn20101128-0.2. I believe this upgrade came from the debian-multimedia stable repo I have enabled.
Does this sound right, and what could I do to fix my VLC playback? This is new territory for me, and I'm slightly surprised that such an upgrade would come from the stable branch of debian-multimedia (although I know this is not an official source).
Yesterday I fresh installed Ubuntu 10.04 64 bit LTS on my Toshiba Laptop. This is my second time with Ubuntu so bear with me. I got everything working even the webcam but it won't play dvd movies. When I go to the DVD player icon and try to open it...its won't because it doesn't recognize the dvd format.I have searched but only end up trying stuff that didn't work for it. I guess what it needs is Codec's.
I could play a particular DVD in totem without any problems immediately before the upgrade. Immediately after the upgrade I could not play that particular DVD. I got the error message below code...
I can play the DVD, but without any voice overs. The music comes in fine, same with the picture. It isn't just VLC. Same problem in Movie Player. Didn't know till just now.
I recently upgraded my girlfriend laptop to 9.10 and now, for some odd reason, when she plays DVDs on her laptop (the most recent attempt was the latest Harry Potter movie) the movie would play back fine but the colors for everything were way off. I've re-added the medibuntu software sources to her system and applied all available updates but it didn't help.
This problem did not occur on my own computer when attempting to play the exact same DVD.
Is there any way to make Ubuntu play sound like Windows 7? I mean when i, for example, listen to music in Windows 7 the sound is much clearer and besides that i can use room correction to obtain a better surround feeling, but when i listen to music in Ubuntu the sound is not very clear and it sounds like stereo even though the sound is played back through all the speakers (the bass is also a little bit to high).
So far i've tried installing the alsa driver and modifying the output levels of each channel, but didn't quite have the same result as the room correction feature in Windows, and the sound wasn't any clearer either. Note: I have an onboard Realtek soundcard and Logitech x530 speakers
I've been running into issues with VLC crashing now and again, particularly when seeking through the current item using the bar (as opposed to Ctrl-Right Arrow/Left Arrow); it may have happened in a few other spots, but that's usually when I'm not at my keyboard. All files are stored locally on my HD, mostly .avi video. For the most part, when I'm using VLC, I've got Firefox and maybe a Nautilus window running as well. CPU use, Memory use, and System load stay pretty well down (and I've never managed to get my swap usage above 120MiB of the 1.2GiB on the Swap partition).
I've tried removing and reinstalling VLC, no dice; about screen lists Ver 1.0.2 Goldeneye. A side effect of this is that, until I restart the system, the screen is unable to be put to sleep at it's timeout; in the notification bar of the top panel, an icon appears and (if the mouse is left there) a little box will appear with text as follows: Session active, not inhibited, screen idle. If you can see this text, your display server is broken and you should notify your distributor. Please see [URL] for more information.
The URL there listed doesn't have any information that seems to be useful, but, I'd presume that VLC does something to prevent the screen turning off while it's playing (a situation where most folks aren't going to be typing or mousing around), which is undone when VLC ends cleanly (and re-opening, then exiting doesn't fix it).
I have libdvdcss, libdvdread (i think it was called), and restricted extras - i even followed the instructions on the documentation. they still wont play. I run 9.10 64bit on my laptop, and 10.04 on my desktop.
On almost each mp3 file I try to play, VLC will "lag" during the first seconds. There may be some screeching noise. It looks like vlc can't keep up with the bitrate, and it "skips" some bits.
This doesn't happen with totem (the default media player).
I have tried loading/playing (many different) dvds via VLC / new install of 10.04 (on a laptop through which I had been able to play / burn / rip dvds until I "upgraded")...this is what transpires:
Errors: Code: Playback failure: DVDRead could not open the disc "/dev/sr0". Your input can't be opened: VLC is unable to open the MRL 'dvd:///dev/sr0'. Check the log for details. The log reveals:
Code: dvdread error: DVDRead cannot open source: /dev/sr0 main error: no access module matched "dvd" main error: open of `dvd:///dev/sr0' failed: no access module matched "dvd".
I have a DVD that I am trying to burn to a disc. What I have is a VIDEO_TS folder. First I burned just that to the disc and it plays fine in my standard DVD player, but when I try to play it back using Ubuntu's Movie Player, it acts like it is going to play for a split second and then goes into stop mode. So, I tried burning the disc again, but this time I added and empty AUDIO_TS folder to it. Still plays fine on the DVD player, but in Movie Player it plays the menu. Only it doesn't show any image, just a '>' symbol that you can move with the mouse.
I'm having some issues with DVD playback. Blu-ray playback is not an issue (at least no more than it is for anyone else using Linux), but when I try to play a DVD the video is garbled and choppy, same as the audio. (see attached picture).
I'm using an Asus BR-04B2T blu-ray reader and an Evgo nVidia gtx460 with nvidia-current drivers.
I removed the blu-ray drive and put a friends dvd drive into my computer to test and see if it's the graphics card or the drive, and the DVD player worked perfectly, flawless playback, so I know it's the drive.
Also the drive is not faulty. Both DVD and Blu-Ray work fine under my windows 7 partition.
I forgot to mention, VLC behaves the same as all other players, as shown in this picture. Also you can almost make out that I'm trying to watch the Simpson's box set my friend got me.
I'm sorry if this was asked before (i know it was but never worked for me) 2 days ago I installed ubuntu 10.10, my very first linux OS and I immediately fell in love with it.The only problem now, is tearing during video playback (I'm a perfectionist with a thing for fine details, so this is literally killing me)
I have nVidia 9200M GS (HP laptop) I've set nVidia setting to sync vblank and disabled it in compiz I've also disabled PowerMizer..
I love the system to give up some vsync issues in moving windows, but i just can't get over video tearing. I'm ready to install anything, change anything, even do a new clean install to get it working. UPDATE: Installed SMPlayer, works fine but drops couple of frames every 5 secs or so (more annoying than tearing lol) is there any specific settings that can fix that?
I am having music playback issues in lucid right now. When I try to play music through any player, the music plays at a slightly higher speed - roughly 10% faster (a 3:17 song finishes in 2:5. I tried installing 10.10 and had the same problem, and I just went back to 10.04 with a fresh install and still seeing the issue. Is this a common problem for people? My sound hardware is the following as reported by lspci
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 50)
For reference, I also have 2 other boxes in the house running 10.04 with different sound hardware with no issues. Their hardware are:
My totem media player hangs a lot.The video playback is not smooth ..as if i am on a very old computer and believe me i am not. though everything runs smooth on vlc . but i'd still prefer totem if it can be fixed.i running ubuntu 10.10 , the graphic card i have is Nvidea 8600GTM
