[Bug 76876] Re: /dev/dsp busy, but no program using it
Using 7.10 gutsy gibbon with newest updates, and i can confirm the same problem. However, did the following right after a clean install, dist-upgrade and login (to be sure there's no weird processes blocking /dev/dsp): $ cat /dev/urandom /dev/dsp bash: /dev/dsp: Device or resource busy $ ps ax | grep esd 15858 ?SL 0:00 /usr/bin/esd -nobeeps $ kill 15858 $ cat /dev/urandom /dev/dsp [add some white noise here] - ctrl+c $ So should be an ESD problem, not FF or Java or something. And the ESD problem is caused by ubuntu running ESD on the background with the option -nobeeps. Killing the ESD process frees the sound card and vóila, sounds working again! Don't know really which package this affects, hopefully someone will take a look at this. ** Summary changed: - /dev/dsp busy, but no program using it + /dev/dsp busy, weird ESD process using it ** Description changed: Previously discussed at http://ubuntuforums.org/showthread.php?t=313755, this bug presents itself to Edgy Eft users, perhaps only ones who upgraded from Dapper. These commands pretty much tell the story: $ sudo fuser /dev/dsp $ sudo lsof /dev/dsp $ sudo cat /dev/urandom /dev/dsp bash: /dev/dsp: Device or resource busy $ The result is that any program dependent on sound is unable to speak with the sound card. After a period of time it will reset itself and sound is restored until it next freezes up. It affects systems using OSS and ALSA. If the user logs out and back in, sound is restored for a time. The only thing I see related to sound in 'ps ax' when the /dev/dsp is busy is a couple esd lines: $ ps ax|grep esd 6322 ?Ss 0:00 /bin/sh -c /usr/bin/esd -terminate -nobeeps -as 1 -spawnfd 19 6323 ?SL 0:06 /usr/bin/esd -terminate -nobeeps -as 1 -spawnfd 19 + + I'm adding some info from Gutsy: + Using 7.10 gutsy gibbon with newest updates, and i can confirm the same problem. + + However, did the following right after a clean install, dist-upgrade and + login (to be sure there's no weird processes blocking /dev/dsp): + + $ cat /dev/urandom /dev/dsp + bash: /dev/dsp: Device or resource busy + $ ps ax | grep esd + 15858 ?

Hi, I had the same problem with this error message Device or resource busy. Command lsof /dev/dsp or /dev/audio gave me no output. But lsof | grep /dev/snd/ showed me some process using files in this directory which is used by ALSA. Killing these process solved my problem.

Juraj: did you use sudo? When you did, your problem is a different one from mine and some others in this discussion. For me, it is clear my /dev/dsp is used by firefox and openoffice, and the question is why these programs use /dev/dsp exclusively. Maybe it should be reported as a bug in these programs?

[Bug 76876] Re: /dev/dsp busy, but no program using it
It made no difference whether I used sudo or not. This bug is called /dev/dsp busy, but no program using it Exclusive usage of /dev/dsp IS NOT a bug. It's a hardware limitation of your sound card, which doesn't support hardware mixing. The Open Sound System (OSS) architecture does NOT support software mixing - therefore, you can't have two or more OSS apps at the same time if your sound card doesn't support hardware mixing. You can recognize OSS by use of /dev/dsp as the audio device. The solutions are few. You can buy a better sound card; you can configure these programs to use Advanced Linux Sound Architecture (ALSA) which supports software mixing; or, you can use the alsa-oss (aoss) wrapper to run OSS programs through ALSA. This what you experience is NOT a bug. It's a limitation of OSS. A bug is when /dev/dsp is busy when no programs are using it. -- /dev/dsp busy, but no program using it https://bugs.launchpad.net/bugs/76876 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 76876] Re: /dev/dsp busy, but no program using it
True, the title should be clear enough. But there are 2 discussions going on here; for example bcdeck, flickerfly and Georges seem to have the same problem as me. By the way, I think it IS a bug. In a distribution, sound should be working, no matter which program I use. That's what you and George said: these programs need an update on its sound management. It would be a bad idea to buy a new sound-card, alsa works fine; as you said too. Anyway, this discussion shouldn't be hold here, since this is another bug, probably of these programs self. -- /dev/dsp busy, but no program using it https://bugs.launchpad.net/bugs/76876 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 76876] Re: /dev/dsp busy, but no program using it
I'm not an Ubuntu user, I use Sidux and came accross this page by accident, but as they are both Debian and the symptoms are the same this might work for a temporary fix: sudo lsof | grep /dev/snd This should just list artsd. Kill it and run your sound app straight after. Once your program has exited artsd is restarted and your program won't have sound again. I know this isn't the answer but, if it does on Ubuntu what it does for my Sidux then, maybe somebody with a bit more knowledge can do something with it. -- /dev/dsp busy, but no program using it https://bugs.launchpad.net/bugs/76876 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

it is flash related and has been also on all previous versions of linux, indifferent of distribution. It may work better with the latest flash plugin (version 9) but I still suspect the java plugin to also mess around with sound in the same way. But the real bug is: how do we find out which program is responsible of blocking /dev/dsp. For the moment I just do a random kill here and there until I get my sound back.

I'm still having this problem on Edgy. I have an update though. I'm working some more on digging up dirt. I've tried killing off certain things that are suggested to be related and then run 'ps ax|grep esd' and I'm finding that I don't have any esd related things in the list so that would seem to be unrelated.
