Ubuntu Multimedia :: Why Are Devices Detected Even When Disabled In BIOS
Dec 5, 2010
I am having problems understanding how sound capable devices are being used on my Ubuntu10.10 64 bit system. I have an ASUS A8V motherboard with on-board multimedia functions provided through the VIA V8237 chip. BIOS gives me the option to disable this functionality and I have set BIOS this way. I want to use an M-Audio 24/96 card for all sound processing.
However, in applications like Audacity the VIA chip functions are all available and can be set as recording and playback devices. The same is true in ALSA.
Why does 'linux' (I have no idea which part of the OS) ignore the BIOS settings?
Furthermore alsamixer always selects the 'default' devices. Where and how are these set?
<System><Preferences><Sound> hardware tab list 2 'Internal Audio' devices but no M-Audio device. What are these devices? Only 1 of them appears to create any output with the 'Test Speakers' tab. This confuses me completely because the speakers are connected only to the M-Audio card.
None of the profiles for 'Settings for the selected device' match the capabilities of the M-Audio card (1 set of stereo inputs and 1 set of stereo outputs). So where are these profiles coming from? Which do I select for the M-Audio card?
What do the Input and Output tabs in <System><Preferences><Sound> mean? Are these different to the hardware tab? The 'Output' tab lists2 devices for sound output: 'Internal Audio Analog Stereo, Stereo' twice. What devices are these ?

I have a Samsung NC10 and want to use my built in webcam on TokBox. However, when I try to use it, my camera and mic do not work. TokBox gives be a "Devices Disabled" message. It says set to "allow" and click ok, but there is nothing to click. I also can't get the camera to work with video chat in Gmail.
I know the the camera works because I can get it to work in Cheese. The mic, I can't get to work at all. I have gone to the Macromedia site and set the settings to "allow", but still no go.
Both work fine in XP (I have a dual boot), so it's not a hardware problem.
Info:
OS: EasyPeasy 1.6 (same as latest Ubuntu Netbook Edition)
Adobe Flash Player: 10.0.45.2
Browser: Firefox & Chromium (didn't work in either)

I'm having issues getting the nvidia-current drivers working with a GeForce 8400 graphics card on Ubuntu 10.10 (x64). After running nvidia-xconfig and restarting, X fails to start with an error: No devices detected.
Here is my xorg.conf:

Rhythmbox plays some music (not all of it) and it sounds crappy. And when I start Amarok I get this: KDE detected that one or more internal sound devices were removed. Do you want KDE to permanently forget about these devices? This is the list of devices KDE thinks can be removed: Output: HDA Intel (INTEL HDMI) Output: HDA Intel, INTEL HDMI (HDMI Audio Output)What to do?

I've played with Ubuntu, and a linux evangelist at work has talked me into trying it again.I happened to be wiping my machine, so my plan was to have Windows 7 and Ubuntu on one hard drive (100GB for Ubuntu, the rest for Windows), and the second hard drive for downloads, TV, films, etc.First I installed Windows, then I torrented the x64 Ubuntu 10.04 live CD iso, and burned it to a DVD. I booted from it and installed on the second partition, but I then found when I booted back into windows that my second hard drive wasn't there any more.
It didnt take long to work out that Ubuntu had installed using the second hard drive as a mirror. This is very confusing to me, as I've disabled RAID in my BIOS. I booted from the Ubuntu CD again and looked for options about this but didn't find any. Eventually out of frustration I just unplugged the second hard drive, but now when I boot from the CD to install, no hard drives show up for me to install to.

When I moved from Fedora 13 from Fedora 11, I thought the annoying application crashes that I had been having were gone for good. Random crashes - firefox, Thunderbird, Abrt, metacity and what have you with SIGSEGV errors. I'm beginning to believe that these are not down to Fedora or even the RAM (Have run Memtest, several times). I'm not sure if what I am seeing are signs of IRQ conflicts of some sort. Can someone, please have a look and give me some guidance on what to do? Should I reinstall with acpi=off ? noapic? Also, don't have a clue why the system complains of ECC being disabled? The RAM is non-ECC. I have posted some sections of the logs here with links to the full logs instead of making this a massive post.
Code:
EDAC MC: Ver: 2.1.0 Aug 27 2010
EDAC amd64_edac: Ver: 3.3.0 Aug 27 2010
EDAC amd64: This node reports that Memory ECC is currently disabled, set F3x44[22] (0000:00:18.3).
EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
(Note that use of the override may cause unknown side effects.)
amd64_edac: probe of 0000:00:18.2 failed with error -22
Complete system spec, BIOS details etc.
Full dmesg log on a fresh install. No issues experienced with system installation.

I have Ubuntu 10.04 installed on an Asus x83v. About a month ago, my laptop began taking a very long time to boot up, assuming it booted at all. This happened out of the blue for no apparent reason. I found that boot up was faster when I unplugged all USB devices, though it was still a slow process. When I plugged devices back in, they did not work. My iPod was not recognized, nor was my USB mouse. This was extremely frustrating, but I figured it must be an issue with Ubuntu 9.10, and with 10.04 just around the corner, I figured I would upgrade and then see how things were. To make a long story short, it was all the same. With some research, I found that my USB ports were inexplicably disabled.
Here is the output of lsusb:
Code:
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 004: ID 04f2:b071 Chicony Electronics Co., Ltd 2.0M UVC Webcam / CNF7129
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
This is with my USB mouse plugged in.
I went into BIOS and found that USB was enabled. However, on the rare occasion that my computer boots successfully with a USB device plugged in, I get a message like this from Ubuntu prior to reaching the login screen: "Unable to enumerate USB device, Port 002 disabled". I suspect I may need to reinstall my BIOS, however I am at a loss as to how to do so.

Upgraded from 9.04 to 9.10, touchpad on my laptop stopped working, but i had my USB mouse so I upgraded to 10.4. After the reboot, both the USBMouse and touchpad no longer work, rendering my Ubuntu Installation a useless. Luckly I have OpenSuse installed on this laptop as well. I have a Gateway MP6954

I'm running SUSE 11.3 on a Dell Inspiron 1501 with a Broadcom BCM4311. I finally got the wireless working earlier with some help from caf4926 and now the card keeps disappearing almost like someone went into the BIOS and disabled it.

After returning from suspend to disk, RF devices (wlan and bluetooth) are disabled. Running lspci indicates that no wireless network device is available, and no drivers are loaded. Furthermore, the LED on the front of the laptop remains off - this is always on when RF devices are available. There is an Fn-F1 function key to toggle wireless, but this does not function to either enable or disable.
Rebooting the system does not re-enable the RF devices, and there is no option in the BIOS. The only workaround I have at present is to boot into windows vista and use the Fn-F1 function key. This pops up a small hotkey utility with the option to disable/enable the wi-fi and bluetooth (independently). Upon confirming the dialog, the RF device light immediately illuminates. Rebooting into fedora and wireless devices are working once again.
I am running kernel 2.6.31.12-174.2.3.fc12.x86_64, with the latest compat-wireless drivers. I can provide much more debug information (dmidecode, acpidump, boot logs, lspci etc...), I am just unable to determine what is relevant

The brand new MEMOREX 24X Lightscribe DVD player(SATA) is not detected by my UBUNTU 10.10 install (via USB stick LiveCD install). I know it should have worked out-of-the box, but it does not, dmesg or lshw command shows all other SATA connections ( 2 hard drives) , BUT the DVD Drive. The DVD drive is detected by the MSI BIOS, it is also fully functional in the dual-booted Windos 7 installation next to the Ubuntu 10.10, so I know the DVD player is ok. I have the latest B3 Stepping MSI P67A-GD65 motherboard with Intel i7 2600K cpu.

I'm trying to install a second NIC on a computer running 10.10 x64 server edition, but am having a bit of trouble and hoping someone can help. I got a used gigabit PCIe ethernet adapter and hooked it up, but it didn't display when I ran ifconfig, so I assumed that it was broken. However, when I plugged in a known working 10/100 adapter from another machine it also wasn't configured.
I then did a bit of investigating and found that both cards ARE detected, but are unable to work for an unknown reason. Here's the output of "sudo lspci | grep -r Ethernet"
00:08.0 Bridge: nVidia Corporation MCP55 Ethernet (rev a3) 01:07.0 Ethernet controller: ADMtek NC100 Network Everywhere Fast Ethernet 10/100 (rev 11) 02:00.0 Ethernet controller: D-Link System Inc DGE-560T PCI Express Gigabit Ethernet Adapter (rev 11) The bridge is the working onboard NIC, and the others are the ones that I'm trying to get to work. This also might help diagnose the problem:

I am just getting started with Ubuntu and love it so far. It has breathed new life into an old Compaq Presario V2000 and once I get up to speed on it I hope to start running it on all the rest of our machines.
The only major problem I am having is that none of the USB devices I have plugged in are being detected. From what I have seen online I should be getting a notification and should be able to view the devices at Places/Computer but so far, nothing. Googling this problem it appears that individual devices often don't work but I could not find anything on all USB devices not working.
Any ideas as to what I am doing wrong here?

To start with I know this is not a linux problem, it is purely hardware.After the computer has been on for a while and then restarted bios does not detect in POST the usb sticks that it is supposed to use to boot from. his is obviously a problem as bios can't use something it can't see to boot from.I'm wanting to know if anyone else has had a problem like this with my hardware? I suspect it is the Asus M4A78LT-M LE that has a usb detection problem, since I've tried plugging the same sticks in to another pc and they do not have the same issue on that pc.

I recently had a hard drive on a computer (not to be obvious), and I fried the computer. You may ask "well why did you do that?" well, simply because I had accidentally bumped and switched to 220 volts, rather than keeping it at 115 like a sane individual. Anyway, I got a new computer, swapped the hard drive. When I go to boot into ubuntu though, it gives me the following error:
Code:
Ubuntu is running in low-graphics mode
The following error was encountered. You may need to update your configuration to solve this.
(EE) No devices detected.
I also have XP on this hard drive, and it works almost better than it did on my old one, surprisingly. all i have to do now for it to be labeled as efficient, is to get some RAM. But anyway, what can I do about the error message? I tried booting into recovery, running dpkg from the list of options, and it did a couple of things.

Whenever I plug in my usb flash drive or my memory card adapter they are not detected. If you can help me I will provide any kind of information needed to solve the problem, just tell me what command to run. Also my cd/dvd drive is still not being detected or is mislabeled on ubuntu 10.04 lucid lynx.

I have a working F-10 box with an older motherboard (pre-sata). The p-ata ports are full (4 drives), so I'm trying to add a sata controller and another drive. The sata controller plugs into the pci bus, but is not detected by the bios (very old). After booting, the OS loads the driver module(s) and detects the new controller and drive. I was able to add the new sata drive into the LVM system using system-config-lvm. All was fine until I rebooted.
I get pages of lvm errors and booting fails. It looks like it's trying to mount the volumes before the sata controller is modprobed. Is there a way to get the os to modprobe for the new controller before trying to mount? The extra drive space is on a data partition, not the boot partition.

Last week, I received a used, older (built ~ 2005 or so) IBM ThinkCentre desktop (machine 8143-2EU) having a Pentium 4 (64 bit), 3.0 GHz CPU. It came with WinXP- 64 bit as the sole OS. When I tested my USB devices with the WinXP OS, they were detected and read. I wiped the WinXP and installed MEPIS 11- 64 bit. [There's only a single Intel Pentium 4, 64 bit CPU known to work for MEPIS 11- 64 bit. It's the Pentium 4 Prescott with EM64T. I don't know if my P4 is that one.] Things seem OK with my MEPIS 11- 64 bit OS except for the times when I plug in USB devices--> they're not detected nor read. In a MEPIS forum, a guy told me to try, after first plugging in the USB devices, running lsusb in Konsole. I do that, the system wakes up, and the USB devices are detected and read. But why do I have to do this to get my system to detect and read the devices? I've made the MEPIS system setting so that all USB devices are automounted when plugged in. Doing that did not correct this problem. As root, in Konsole, I ran hwinfo and noticed that for the USB controllers, the driver - uhci_hcd - is not active. Here's the hwinfo output for one of the USB controllers:
18: PCI 1d.2: 0c03 USB Controller (UHCI)
[Created at pci.318]
UDI: /org/freedesktop/Hal/devices/pci_8086_265a
[code]...
[I suppose or guess that all MEPIS users who don't have this USB-device-detection-and-read problem have uhci_hcd.] To see what would happen as a test, I also used a MEPIS 11- 32 bit Live DVD in this computer having the MEPIS 11- 64 bit OS. When I use the Live DVD, I have the same USB detection-and-read problem! What does that mean? With some USB devices plugged in while I'm using the Live DVD, I'm forced again to run lsusb in Konsole. This wakes up the system so that it detects and reads plugged-in USP devices. Why? Any idea on how to fix this? Does this problem seem more a software one rather than a hardware one?

I have been running Ubuntu 9.04 for the past year. Tonight decided to upgrade to 9.10 thru update manager. Every thing regarding the install seemed fine until the request to restart the computer. I hit the restart and it will not boot up. Computer goes thru the normal restart screens.
Screen flashes with bios info--no hard drive detected, then proceeds to show booting from hd, then loads grub stage 1.5 (not grub 2)and screen goes blank.

I have had this issue before, and fixed it by booting into Windows XP SP3 and pressing and holding the power button down until the computer shuts down. (e.g. "Unclean or "Illegal" or "Cold" boot.) Unfortunately, not having Windows XP SP3 on my system anymore, I have to do this in Ubuntu. I have tried several times, and it is clearly not working. I don't want to try too many times more for fear of damaging my ext4 file system.
I looked for this issue on Google and found only driver problems, not device problems. There is no Ethernet option in the BIOS, except for the Network Boot, which should always show the device whether its in use or not. Is it silly to ask if Windows in a VM in an unclean shutdown may solve the problem? The driver for the device is currently supported by the kernel out of the box:
Code:
Linux brokenbox 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 16:20:31 UTC 2009 i686 GNU/Linux
It uses/used the atl1c driver. It was working on the same install just about a day ago!

I dl the windows installer one and ran it. As it started it went to the Ubuntu logo and then my screen became half full of different colored horizontal lines, so I rebooted and went into the adv boot and ran the install under safe graphics mode. Now when I boot I get options to boot into 2.6.32-25 and also a recovery and also 2.6.32.24 and a recovery. I left the 2.6.32-25 highlighted and it booted but gave me a msg that said:
(EE) VESA: Kernal modesetting driver in use, refusing to load.
(EE) No devices detected.
Then it goes to a screen that allows me to boot in a low graphics mode. It loads and I dl some security updates with the Update Manager. What do I need to do in order to boot w/o any faults and also what is the difference from 2.6.32-25 and 2.6.32-24? Which should I be using? Do I need to modify my graphis somehow?

Before I changed to linux, I was on Windows 7. My computer already had 4 different partitions, and would not let me create more. And so, I had to delete one of the partitions. I chose to get rid of the "recovery" partition. I used "Macrium Reflect" to burn a bootable CD of my recovery stuff. Anyways, fast forward to this morning. I got tired of the KDE desktop, and I decided to switch to Gnome. So, I went into windows 7, deleted the three OpenSUSE partitions, and moved the remaining space back to my C: (windows) drive. (don't ask me why :S)
Anyways, so I take a look, after it's done deleting/moving stuff, and I'm told that "no bootable devices detected".. This made me angry, as I am certain I didn't delete any of the windows partitions. So, I thought, I'll just use my recovery disk, because I quite literally, have no personal data on my computer to lose.Except, my recovery disk is not actually bootable. So, then, after screaming in rage, I booted up OpenSUSE from my KDE CD, and was gonna take a look at things in YaST. Except, YaST will not actually open.
