Ubuntu :: Randomly: No Audio - Can't Mount USB Flash/DVDs - Can't Shutdown

May 10, 2010

I have just installed Lucid i386 on an intel Core2Duo. Everything seems to be OK but about a third of the times I boot the system the following happen:

1) aplay -l reports no soundcards found and therefore I have no sound whatsoever

2) I cannot mount any USB Flash drives or DVD discs and I keep getting "Not authorized" error messages plugging them in.

3) The system won't reboot/shutdown by the gnome applet. Instead, it will drop back to the login screen asking my login. Furthermore, it won't even shutdown from there! Only a poweroff or reboot from command line can work.

4) The gnome applet "Indicator applet session" only shows "Log out, Restart, Shutdown". Suspend and Hibernate options are missing.

Furthermore, it seems that I am the only one who has these issues. My sound card is an onboard HDA Intel although this seems to be that something else dies taking some major subsystems down with it. Any ideas?

/proc/asound/cards shows:

0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe028000 irq 23
but: aplay -l
aplay: device_list:223: no soundcards found...

Ubuntu Multimedia :: Recording TV Audio / Video With DVDs?

Oct 4, 2010

First up, let me say this post has almost nothing to do with Ubuntu, so you may ask: Then why am I here? I am here because I didn't know where else to turn.

My main problem here is that I would like to be able to record myself playing a video game on my TV, and be able to toss the file onto my computer to edit/upload. I've heard of 'Dazzle' those TV recorder things, but I'm looking for more of a home quickfix.

What I was thinking of doing was hooking up a DVD player to a tv. Then hooking up my wii to the DVD player, to the TV. This way the game would be displayed on channel three. If I were to do this, would I be able to put a blank DVD in the drive, and set it to record channel three? Since channel three will be my game, would it record the video game? I'm sure if it would, it wouldn't be the best quality.

Ubuntu Multimedia :: No Flash Audio - Can't Hear Any Sound From Flash Content Displayed In Fire Fox

Sep 26, 2010

I recently installed Ubuntu 10.10 AMD64 beta. After installing the flash player, everything worked fine. I installed a few updates, as well as Ubuntu Stuido from the synaptic package manager, and when I rebooted, I can't hear any sound from flash content displayed in Fire Fox. All other sounds work fine, and I made another user account as a test, and that account has full audio functionality, including flash...

Ubuntu :: Last Few Burned DVDs Won't Mount?

Jul 30, 2010

I've been backing up some data recently because I'm planning to upgrade to 10.04. It had been going well until today. I burned a couple DVDs, tested them, and they were fine. I burned another one, tested it, and it wouldn't mount. Got the following: "Unable to mount media. There is probably no media in the drive." (Was using K3b).

I tried the same one again, this time using GnomeBaker. Seemed to burn alright, but once again would not mount when I tested it. So, I thought maybe it's just this one particular folder. I tried to burn a DVD with completely different data. Same thing, seemed to burn OK, but again it will not mount.

I went back and re-tested the DVDs that worked OK earlier today, and these ones are still mounting. Any ideas? Did my burner suddenly go bad? Or does someone know of any other possibilities that hopefully could be fixed? -using Verbatim 16x DVD-Rs (burned on 8x)-Lite-On SHW-160P6S

-Ubuntu 8.10
-755 MB RAM
-Intel Xeon CPU 1.70GHz
-used no multisession (or finalized in Gnomebaker)
-used linux+windows filesystem

-I was burning mostly video files (.avi, a couple of .wmv, couple of text files, subfolders with other .avi, etc.)--basically the same type of data whether they could mount or not.

Ubuntu Multimedia :: Audio Playback Randomly Stopping?

Mar 2, 2010

I've been tweaking my kernel for RT performance over the past few days, and just recently, it's begun randomly cutting sound playback, and I can't seem to figure out why.

Was watching a movie last night using VLC, and about 5 minutes in, sound playback just totally stopped while video kept working. Sound driver in VLC was set to Pulseaudio. I switched it to ALSA and the problem seemed fixed.

In Decibel Audio Player, the tracks randomly just stop in the middle of a song occasionally (every 5 songs or so, give or take), and a little red 'X' appears next to the track that got "skipped." Screenshot:

Don't recall it happening before I tweaked all the RT audio settings.

Ubuntu :: Sound Randomly Mutes On Streaming Audio / Video

Aug 19, 2010

I have a gigabyte MB/rig connected to Svideo out on my TV. I have external PC speakers connected to my sound card. For some reason when I go to play video, streaming audio, or streaming video I get no sound. I go into alsamixer via CLI and all is unmuted. I reboot, sound is back. The next day I load boxee, no sound. It's not just boxee when I have no sound. If I close boxee and open vlc and stream online radio, I get no sound either. Reboot, sound is back. No external errors of hardware conflicts either.
Running Ubuntu 10.04, 64bit , kernel 2.6.32-24-generic

Ubuntu Multimedia :: VLC / Phonon Randomly Drops Audio Stream

May 24, 2011

I have an Asus EEPC that I use in my classroom whenever I want to show a movie. I normally keep all of my educational videos as ISOs, and then simply move one over to the netbook when needed. I normally use VLC for playback. With the latest upgrade, however, I'm having a few difficulties. No matter what DVD I choose to show with VLC, the audio stream will randomly drop every 10 minutes or so whenever I am using KDE as my desktop environment. In order to re-enable the audio stream, I have to either completely stop playback OR reconfigure the audio output in VLC.

(It does not matter if I change it right back to what it was, I will get audio for another 10 minutes or so). I've also noticed that if I pause playback, sometimes the audio will not re-enable when unpaused. Strangely, however, I do not have this behavior at all when I'm using Gnome as the desktop environment. I get seamless audiovisual playback and never have to fiddle with the audio. Is this a documented problem in Phonon somewhere? How I might better backtrace what's going on?

OpenSUSE :: Burn DVDs But Cannot Mount Them?

Feb 9, 2010

I am able to burn DVDs with either Brasero or k3b, but opensuse then cannot mount them .

Those DVDs do contain the burned data since I can see it and read it on a Mac...

On openSUSE, I get the following error when inserting the DVD :

I added my user to 'disk' and 'cdrom' groups, but to no avail.

Here's the output from dmesg :

Code:

Hardware :: Some CDs / DVDs Do Not Automatically Mount

Jun 5, 2010

I have checked out 'similar threads' to no avail. I am using Mandriva 2010 on /dev/sda6. I have two Pioneer CD/DVD drives. Some data CDs/DVDs automatically mount. Some do not show up in Dolphin's 'Places'. I tested many. Age of disk, brand name and whether pen parked gave no significant correlation. Using PCLinuxOS 2010 (live disk) created the same problem - not altogether surprising. But using Ubuntu 9.04 (live disk) created no problem.

Booting with slightly different kernel versions solved nothing. Using Windows XP or Mandriva 2009.1, both on other partitions, created no problem but when I tried Ubuntu 10.04 (live disk) I had 'no signal'. I have just put in a new Radeon (later than HD 2000) video card (fglrx) so I wondered if Ubuntu does not like it but this issue is unimportant - if Mandriva 2010 can be tamed. What did correlate was that both drives either recognised or both ignored any particular disk. Manual mounting as root works okay but my wife is not comfortable with the CLI.

The fstab file is below:
# Entry for /dev/sda6 :
UUID=14353eb6-82ff-45cc-ae64-8eed13800b46 / ext3 defaults 1 1
/dev/sr0 /media/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0
/dev/sr1 /media/cdrom1 auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0
none /proc proc defaults 0 0
# Entry for /dev/sda5 :
UUID=07e9f3ee-d92e-4696-b762-03a07ed102d2 swap swap defaults 0 0

I checked but could not positively identify this issue as a known bug in Mandriva 2010.

Ubuntu Multimedia :: Connexant / NVidia Audio Just Randomly Stopped Working?

Mar 18, 2011

My Compaq Presario F739WM laptop has a Connexant HD Audio/NVidia MCP51 (reported by lspci) sound card.Ubuntu has always supported the card with no problem except the random popping noise but then I found a work around for that.Now for some reason, when I first turn on my computer and at login screen I can hear Ubuntu noises, yet seems once I login, no more sound or sometimes the successfully logged in sound.

The only changes that I have since the sound worked, was I installed pulseaudio but that caused no problems with that. The other change was a few kernel upgrades and other packages through normal update manager.I have checked that snd_hda_intel driver was loaded in the kernel and in alsa, all seems well.Pulse detects audio output in it's meter.I also tested the sound card to make sure it wasn't bad, in Windows 7 (dual boot) and it wokrs perfectly.

General :: Transfer 4 Versions Of Vista And Windows-7 Installation DVDs Into A Flash Drive?

Jun 17, 2010

How to Transfer 4 versions of Vista and Windows-7 installation DVDs into a flash drive The recent versions of MS Windows of Vista and Windows 7 installers support booting from a USB device so it is possible to transfer the contents of the installation DVD to a flash drive and use it for booting. A USB flash drive however is classified by M$ as a �Super floppy� that can only have one partition. This means one flash drive can store one MS Windows boot loader.

This tutorial shows how to use Grub, a Linux boot loader, to boot 4 Vista/Windows 7 installation in one flash drive. Technical consideration

(1) I have checked to my satisfaction that none of the MS Windows of Win2k, Xp, Vista and Win7 can mount or see more than one partition in a flash drive. That doesn't mean the user can't have multiple partitions. It is just MS systems have been engineered to mount the first one it recognises and disregards the rest.

(2) MS Windows installers of Vista and Win7 do not like to be booted from a logical partition. As a flash drive with a Msdos partition table can have a maximum 4 primary partitions hence this tutorial describes 4 versions of MS Windows installers of Vista Home-32, Win7 Ultimate-32, Vista Home-64 and Win7 professional-64

Ubuntu :: Freezing With Flash - Screen Randomly Whited Out Fading In Splotches To Black And Then Back To White

Dec 18, 2010

I am having a problem. I am running Ubuntu 10.04 on a Sony Vaio FW series. It has Nvidia graphics that I don't think the OS is taking advantage of, whatever. It also came with 64-bit Windows, it's a 32-bit OS, and again, as far as I have been concerned, whatever. It's been functioning fine for the half a year since I installed it.

Until recently. My computer has been freezing. What happened first is that the screen randomly whited out, fading in splotches to black and then back to white. This freaked me out, but restarting seemed to smooth things out. Then windows in the OS wouldn't resize, then Flash videos would freeze the OS up, repeating the 2 seconds of sound it last played. Over and over again. In a loop. On a white screen. Sometimes with vertical stripes.

This all happens inconsistently, and whenever I restart it's fine again. I just want to know if there's a deeper issue so that I can resolve it. Otherwise I have been completely satisfied, as a previous Windows and OSX user who is computer-competent within a GUI.

Installation :: 8GB Flash Drive Because My D Drive Doesn't Read DVDs?

Jun 20, 2010

I bought an 8GB flash drive because my D drive doesn't read DVDs. Anyway, my goal is to install Linux ubuntu and have it be my OS (replacing Windows XP). Last night I went to the Ubuntu homepage and downloaded the Ubuntu desktop edition 32-bit and put it on my flash drive. I followed the instructions on how to open and run it, but I was never asked about whether I want Linux to run side by side with Windows or if I want it to replace Windows. It downloaded the whole program, my computer restarted and then (on a black screen) it asked if I wanted to use Windows XP Home Edition or Linux Ubuntu. It's really frustrating because it took a while to download and install it in the first place AND to top that off, when I tried to use Ubuntu it went to a black screen and at the top said that there was an error. So I uninstalled all the ubuntu program and software and now I have a clean slate and want to try this again. I am a complete n00b. Could someone please walk me through how I can go about downloading (w/ links plz), installing and making ubuntu my ONLY OS on my computer via a flash drive? I'm desperate and I don't want to go through all of that and make the same mistake again!

Ubuntu :: Flash - 2 Second Delay In Audio

Jan 1, 2011

Using 64bit 10.10, when I click any of the controls that manipulate sound, such as pause, play, or changing volume, there is a 2 second delay before it takes effects, some examples:

- If I hit Play, then the video will begin to play but I hear no audio for 2 seconds, then the sound will begin in sync.
- If I adjust the volume it takes 2 seconds for it to actually change.
- If I hit pause it will immediately pause the video portion, but the sound continues for an additional 2 seconds before stopping.

I have seen numerous people on Google with my problem by googling "flash delay ubuntu". I do not believe this is related to pulseaudio, etc. that I know of, but seems to only occur using Flash as far as I am aware.

Ubuntu Multimedia :: No Audio In Flash Videos?

The sound card works properly with any other application, such as Amarok, but not with flash videos and my hardware is mostly Intel witch is linux-friendly from what I know, so I guess that it isn't a driver problem. Therefore, I switched from windows to linux only a couple days ago, so it may be a newbie issue as well.
