CentOS 5 Hardware :: In 5.3 Two Applications Cannot Use The Audio Device At A Time
Sep 19, 2009
I just installed centos 5.1 on my laptop. Then i upgraded it to 5.3. The problem that i am facing is that at a time only one application can use the audio device. Is this some kind of driver problem or an error in Centos? If one application is using the audio device and if i start the other application that also want to use the audio device it simply gives an error like audio device is locked by other application and is muted. In windows XP my audio device is shown as Sigmatel Audio.

I am new to Linux and after a lot of research I settled on CentOS to be my OS for Linux. But I am having trouble with sound right now as I can not play audio. The command system-config-soundcard opened a gui for audio configuration saying following device is detected - Intel Corp. 82801(ICH9 Family) HD Audio Controller.
Ouput for some commands are given below::
[root@localhost ~]# lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) .....
[root@localhost ~]# uname -r
2.6.18-164.el5
[root@localhost ~]# cat /etc/redhat-release
CentOS release 5.4 (Final)
Clicking on the volume icon gives me message that either Gstreamer plugins are not installed or sound card is not configured.
While Trying to install gstreamer using YUM, I got following message:
[root@localhost ~]# yum install gstreamer
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile .....
Setting up Install Process
Package gstreamer-0.10.20-3.el5.x86_64 already installed and latest version
Package gstreamer-0.10.20-3.el5.i386 already installed and latest version
Nothing to do
[root@localhost ~]#
So I guess gstreamer are installed but how to configure the sound card or is there any other problem.

I have behringer UCA202 usb card, after plug to usb, it just works , I have only small problem with alsamixer, which still shows by default my integrated HDA Intel, I could switch it by F6 or by alsamixer -c 1no problem, but I expect that default card is now plugged "USB audio", so why alsamixer recognize default audio device as HDA intel and not a USB Audio ?anyone who has two or more sound cards with the same issue ?

For those that use Virtualbox on their slackware host and have a windows (xp) guest running. I have tried various settings for sound (Alsa, PulseAudio), the AC97 drivers are installed in the Windows xp guest os, but there is no sound and there is an unknown audio device (in the windows device manager). If I remove the AC97 drivers and use the soundblaster16 drivers in the Vbox settings there is no unknown sound device, but there's still no sound. why I can't get sound working?

I'd like to use one of my machines for all kinds of audio applications, including home recording (MIDI and analog). Now I am looking for a suitable audio/recording interface. I've searched the web, but didn't find a lot of current information. Most of what I found is outdated.
RME Hammerfall seems to be brilliant, but exceeds my budget. MAudio 2496 seems to be excellent in quality, but a bit limited in connectivity. ESI Juli@ appears to be even better, but the parts exposed to the outside of the computer case don't seem to be overly robust..And that seem already to be all PCI devices supported by ALSA for my purpose! (MAudio Audiophile 192, e. g., is reported not to work that well).
Now I thought, I could avoid all this hassle by choosing a USB device. However, situation seems to be even worse. Terratec DMX 6Fire USB is not supported, at all, MAudio Fast Track Pro is limited to USB 1.1 and 48kHz (I want 96 kHz, at least!) only and requires a patch for 24 Bits. And so on...

In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..

I am hosting two Virtual Servers both running Centos 5.3 on a host machine also running the same OS. The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.

For some reason Java Applications running through Firefox have no audio, Java applications running through the java -jre command do run with working audio though. I don't know what else I need to post, but this is what I've been getting. Audio does seem to work with most of my other applications and games.

Its unbelivable how crappy Sound in Ubuntu is - i am suffering from this since karmic. Whenever a second appication like Firefox plys a tune my sound in Amarok dies. Even windows 3.1 was able to do this kind of Multitasking and afaik this also was possible WITHOUT this Pulseaudio desaster.
This is my config
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog]
Subdevices: 1/2
Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
card 0: SB [HDA ATI SB], device 1: VT1708S Digital [VT1708S Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
(1)ch90045@cyclops:$~/cat /proc/asound/version

This sound desaster makes me really think of buying a windows 7 license.

Background information: So you know how we choose from a list what applications we want associated with a file type? It's a menu full of applications.I've filled mine with different applications I've reinstalled. There are many repeats of application names, with the only difference being most of them don't work. This is due to changing the installation location, via WINEPREFIX. No biggie.I'm also using Ubuntu 10.10. It's very nice!
Problem: How in the world do I get rid of these unwanted list items? It's very hard to find the ones that are good.
Plan B: The easiest solution, so far, is to reinstall ubuntu and install these applications correctly the first time. Then I won't have all of those repeats.

Most applications including flash, znes, have a audio delay about 3 seconds I'm not very experienced with Ubuntu so try not to talk over my head, I'm running on the latest version available from the site desktop version and my computer setup is as follows.
Dell Dimension 3000
Processor: Intel(R) Celeron(R) 2.53 GHz
80 Gb Harddrive with at least 20gb free
I don't really know where else to find information about this system, so if you need additional information you will need to direct me how to find it.

I run a mostly untouched CentOS server, nothing is installed except a server app to store data. The server has been crashing lately - after a year of no problems, so I looked into the logs of it and noticed weird discrepancies in the time around the time it crashs. So I started "watch date >> datefile" and this is what happens:
Code: Sun Oct 17 09:52:45 CEST 2010
Sun Oct 17 09:52:47 CEST 2010

I am currently running debian lenny on an old mini ITX box (1GHZ 1GB ram OS on a 16GB CF card, 4 X 1TB sata drives) as a file server on my home network. I have modified /etc/inittab to auto log in a standard user, start X and start fluxbox. I would like the system to then start a couple of VM's using virtual Box but as this is not a high spec box I would like to start these automatically at 5 min intervals and about 5 min after the auto log in.
Does anyone have any suggestions on how i can achieve this or alternativley monitor the processor load and start each VM in sequence as the porcessor load drops below 20%.

I want to record conversations and stuff from skype. Now, I want the sound to be as good as possible, so what settings do I choose, what do I mute and all the other volume combinations and settings do I configure etc... To get the best record possible, I need to record from both pc and mic at the same time, but how? As my settings are now I can only record through the mic. So, what do I do? Also, if you could give me a few tips on how I can filter useless background noise.

I need to set the default input device to be the microphone on my webcam for when I skype, but it seems to keep resetting itself, so I keep going in and changing it.
I am right clicking the volume icon and going into Sound Prefs -> Input, and selecting the camera.
How do I stop it from forgetting this and resetting it?

I need to capture from my webcam. It has a mic too.I can specify video input device as /dev/video0.I specified input audio device as /dev/dsp2 ( OSS device, corresponding to USB Webcam), Now VLC throws an error, "VLC is unable to open the MRL 'alsa:///dev/dsp2'. Check the log for details".Thinking it wants an alsa device, I specify device as /dev/snd/pcmC2D0c. (got it from kinfocenter and dolphin). Now again an error, "VLC is unable to open the MRL 'alsa:///dev/snd/pcmC2D0c'. Check the log for details.".I try with any device, the same error. I have added myself to audio device so that I can read/write to the mentioned devices.I see no way of switching VLC to use OSS. And I see no information (documentation on net) on it's expected device listing for audio.

Every time I log in, I get the following notification from Phonon: The audio playback device does not work. Falling back to RV635 Audio device [Radeon HD 3600 Series] Digital Stereo (HDMI) and of course, I get no sound.
Sound is integrated Intel HD "82801I (ICH9 Family) HD Audio Controller" (courtesy of lshw), and it did work before, it just seems to have appeared suddenly out of nowhere, I can't even tell when and whether it's connected to any updates or other configuration changes.
