Ubuntu Multimedia :: ALSA Device Has A Broken Timer
Jun 4, 2011
I have a Lubuntu installed Netbook (Toshiba NB200). When I try to watch a video and listen to music smoothly. So I started the program Audacious on the terminal and I get the following Warning Message:
Code:
** WARNING **
Audacious has detected that your ALSA device has a broken timer. A workaround
is being used to prevent CPU overload. report this problem to your
Linux distributor or to the ALSA developers.

I recently bought a logitech headset which is working very nice, the thing is that I cannot make it my default device when I plug it in. I edited /etc/modprobe.d/alsa-base.conf to make snd-usb-audio the default card but it only works when the computer is turned on with the headset plugged in. A workaround is to plug it and then "alsa force-reload" but I find it very ugly plus it kills all apps using audio and leaves the volume indicator unstable.

I was having issues with the mic or line in on my onboard sound card, while trying to get my tvtuner patched in, later I gave OSS a try, I could not get it to work and decided to go back to Alsa, now my soundcard is not functioning.I have followed quite a few different guides, one of which is the sticky, please forgive me for not remembering which guides. I'm going nuts over this.As you can see below it looks like it is still using the oss driver.
uname -a
Linux freekbox 2.6.31-21-generic #59-Ubuntu SMP Wed Mar 24 07:28:56 UTC 2010 i686 GNU/Linux
aplay -l

Using debian testing.
Pulseaudio got installed by default here during installtion. Since I don't want it I first ran "systemctl disable pulseaudio", "pulseaudio --kill", then without rebooting I use mpd with alsa alone and it worked fine.
But then i rebooted, and now all applications, mpd, mpv, chromium etc just says that alsa returns with "Device or resource busy", tried rebooting again with no effect.
The soundcard appears as card 1 according to the output of "aplay -l", and defined that card 1is suposed to be default with this in "/etc/asound.conf":
Code: Select allpcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
It occurred to me that there might be an issue with permissions to the soundcard so I ran "ls -l /dev/snd"
Code: Select alldrwxr-xr-x 2 root root 80 Mar 31 03:27 by-path
crw-rw----+ 1 root audio 116, 8 Mar 31 03:27 controlC0
crw-rw----+ 1 root audio 116, 2 Mar 31 03:27 controlC1
crw-rw----+ 1 root audio 116, 12 Mar 31 03:27 hwC0D0
crw-rw----+ 1 root audio 116, 7 Mar 31 03:27 hwC1D0
[Code] ....
My user is a part of the audio group:
Code: Select alluid=1000(roberth) gid=1000(roberth) groups=1000(roberth),24(cdrom),25(floppy),29(audio),30(dip),44(video),46(plugdev),108(netdev),111(scanner)
As far as I can tell, that looks fine unless I am missing something?

I have recently been forced to do a hardware upgrade (my previous mobo died). Now, sounds works ok with,amarok because kde has recognized the new hardware and switched to it.
..... does not work, likely because flash uses alsa-oss which is probably not configured automatically. I have tried uninstalling and reinstalling both alsa-oss and flash, but it didn't solve the problem.

I am still struggling with getting my HDMI working under Ubuntu lucid. I added the ricotz/unstable repositories to get the latest version of ALSA (1.0.23):
Code:
sudo add-apt-repository ppa:ricotz/unstable
sudo apt-get update
sudo apt-get upgrade
All 1.0.23 related packages were installed (Alsa base, alsa utils, libasound).If I check the ALSA version in /proc/asound:
Code:
bas@ubuntu-lt:~$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21. Result, still no HDMI ports available when I type aplay -l:
Code:
bas@ubuntu-lt:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC272 Analog [ALC272 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
I got this working under Karmic. What am I doing wrong?

I'm trying to monitor (listen to) a second ALSA device on the default first card (#0). The device seems properly configured - for example, Audacity can select the device and record from it just fine; and when I select "Start Monitoring" in the volume level menu (the small triangle..), the volume level reacts to the captured stream. The only thing missing is the actual sound.
Before going any further, here are my specs; up-to-date Debian Squeeze on amd64 (x86_64), kernel 2.6.33.2.
Output of aplay -l:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: VT1828S Analog [VT1828S Analog]
Subdevices: 1/2
[Code]...
p.s. In case you feel inclined to tell me the command above should be just fine for me and not to waste my time with looking for an easier way; that only works when no other application has the default device (or the second device!) in its claws.
p.s.#2 : You probably noticed that the device is actually the third ALSA device. The real second device has no playback. I'm assuming this is no problem, since the same problem applies to that card.

I have Banshee's alarm plugin installed. From Banshee's menu, I click on Tools → Alarm Clock → Sleep Timer. The timer looks like it should be set according to 24-hour time, so I set it for 2 minutes past the current time and click "Okay". The timer doesn't turn off the music when the designated time comes and goes. Thinking that maybe it's a countdown timer, I just set the thing to 2 minutes, but 2 minutes later the music keeps playing on and on. I go Tools → Alarm Clock → Alarm and put a check mark in "Enable Alarm" and try the sleep timer again, but still it doesn't work. I'm running 10.04 64-bit.

I'm running 9.10. I was installing ALSA so that I could run my EMU 1616, and when I tried to go through the steps to install, I'm running into two errors that I've noticed so far. I think. Anyway, the first is that is states that the panelw library isn't there, and that alsamixer: function snd_ctl_open failed for default: No such device or address. The alsamixer one is really odd, since it's there, but I don't know why it won't run.
I initially had it running, and now it isn't. I've yet to get sound out of my EMU. the terminal window also tells me that it can't find the snd_emu file, even though it exists on the computer as well. I need an answer for a dummy.

I'm trying to update ALSA, following the instructions here: SDB:Alsa-update - openSUSE.I'm not sure how to proceed at STEP THREE. There are two sets of instructions, based on whether or not the kernel has been updated. I'm not sure if it has been. How can I make sure?

If I loop the file entirely it works, but that's not helping me. (I'm actually keeping the C option for last since shell programming is less restrictive.

I'm currently using Ubuntu 9.10 and since I've installed it, I don't have any sounds at all. Sounds work fine on windows. My version of alsa is 1.0.21. I made sure that I've got nothing muted in alsa mixer and it seems that ubuntu detects my sound card.
Card is HDA ATI SB
Chip: IDT 92HD75B2X5

Having had many problems with pulseaudio on a fresh karmic install, I followed some recommended instructions for removing pulse and using alsa (URL...). unfortunately, both pulse and alsa have gone and i'm left with oss which seems to work fine. I'd like to have alsa back though.When I open amarok, it plays the frst song on the playlist then pops up a series of 'could not initialise sound engine' messages, and crashes.

Ubuntu 10.04, 64 bit. Sound was working well, thought I would run some scripts [URL] to install the latest version of alsa, but now I have no sound at all. The command aplay -l gives:
aplay: device_list:223: no soundcards found...
and the command
cat /proc/asound/version
produces:
cat: /proc/asound/version: No such file or directory
I no longer have a directory /proc/asound.If I open the window system>preferences>sound
there are no entries under hardware or output.I have tried to re-install alsa with this command:
sudo apt-get install --reinstall alsa-base alsa-tools alsa-tools-gui alsa-utils alsa-oss linux-sound-base alsamixergui
but still no sound.

I'm having trouble after installing Lubuntu-desktop on top of a Ubuntu Server (64 bit). about the reason for this abomination of distributions is to achieve 64 bit Lubuntu. I used to run Ubuntu 64 straight, but didn't like Unity at all; Arch Linux was great up until now, but I'd like to settle down and focus more on productivity.
The situation is thus: I cannot manage to make my X-Fi USB sound card work without hacks, and at best it only works in some applications. I *think* it may be a bug in ALSA, but I had no problem in the latest versions of Ubuntu (11.04 as of this) and Xubuntu even (11.04?).
I can currently only play media in VLC media player using the following hack in my ~./asoundrc
Code:
This works as expected, but not for many applications (which fail to launch, with a error message related to below (no mixer controls))
Code:
What could I be missing? Some diagnostic information (any other information on request):

Running songbird, have been just fine for months, now every time I try to play a file I get "autoaudiosink and alsasink are missing." I can cure this by following the "Getting the ALSA drivers from a *fresh* kernel" instructions in the comprehensive sound solutions guide. But I have to do this *every time* I restart my computer. How can I fix this permanently?

I have an HP-dc5800 computer, and my internal speaker was not working, no matter what i did. However, i could get sound with headphones. Here is what i did to fix it. It may work for you.
sudo gedit /etc/modprobe.d/alsa-base.conf Add options snd-hda-intel model=hp-m4 enable_msi=1 to the end of the file. I changed model=hp-m4 to model=hp-dc5800. So, changing the model to the model of your computer may work. Underneath that, i put in; options snd-hda-intel enable=1 enable_msi=1 single_cmd=1 power_save_controller=1 here is a list of some of the models. http://www.kernel.org/doc/Documentat...dio-Models.txt

I tried to install OSS to see if it would allow my mircophone to work properly in the WinXP guest I was running in VirtualBox. I couldn't get it to install properly so now I'm left without any sound on my system. I was wondering how I could get rid of what ever files from OSS that are left and reinstall ALSA.I'm running Ubuntu 9.10.

OSS, even though it's emulated *through* ALSA, consumes a microscopic fraction of straight ALSA's CPU usage. For example, when I'm playing something through ALSA with XMMS2, I'm getting about 25-30% CPU usage, but with OSS output, only 2%, tops. The same applies to any other application in which I can choose the output method. And, I'm on 10.04.

My audio was working just fine up until today, when I was working on some audio production stuff. I did QjackCtl, and also ran pulse-jack so I could use another app not in jack. Now, upon a boot up, there is no gnome-volume-control-applet or gnome-volume-control running. When I run gnome-volume-control it says there is no sound device (without Jack running). When I do it with Jack and Pulseaudio running (doing QjackCtl and pulse-jack), gnome-volume-control shows info about jack, but no hardware. I have sound, I just can't affect it volume-wise, etc. When I run pacmd I get this:
$ pacmd
Daemon not responding.
When I close QjackCtl I then get an error in a window that says merely: Waiting for sound system to respond.

I have Ubuntu Lucid. If i dont' mistake, it should be possible to hear several applications playing sound simultaneously, with ALSA. But if 1 app is already playing, then starting a second one give always "device is busy".

I finally ditched PulseAudio and set up my system with a realtime kernel. I'm redirecting ALSA over JACK. The good: - Awesome, I can get <5ms latency without any xruns! (although 23.2 msec as described below is just fine for me) The bad: - I'm a long-time linux audio user, but have got some minor issues which spoil the fun.
1. Without pulseaudio, the indicator applet refuses to show a volume control applet. The old gnome-volume-control-applet (the one with tooltip!) loads but doesn't show in the gnome-panel. Although I can set the volume with envy24control, it's not quite as practical as using the scrollwheel! Any way to fix this?
2. When I launching any application (such as a terminal) from the gnome-panel, a new JACK connection is created, but not cleaned up after closing the application. As a result, the QJackCtl connection list is flooded with alsa-jack.jackP.8528.xx connections (where 8528 is the process ID of gnome-panel). The jack_lsp command line program shows the same (added spaces after every : to get around the smiley filter):

I recently converted an amd 64 bit WINdows machine to Lucid 64 bit. Everything has gone well. I had numerous issues with Pulseaudio that I removed it. Sound with Alsa has been great, including system theme sounds. I can record via a mike as well. What I cannot do is to capture sounds coming through the sound card. When I record I am getting empty files. The mixer indicates that there are two capture devices. Here is some data on my audio card.
