 Posted: Mon Jan 17, 2005 3:15 pm Post subject: /dev/dsp disappeared [partially solved] |
 |
|
I recently updated a few things including compiling and installing a few kernels and now /dev/dsp doesn't exist any more. I've done a whole bunch of searching and can't find anything useful. I use alsa and kernel level oss emulation. I'm now running 2.6.10 vanilla. I tried booting 2.6.9-mm1 and it still didn't exist. This was definatly working with 2.6.9-mm1 but I've recompiled that version of the kernel recently and I'm not sure that it's worked since then (although it may have). I use the alsa driver that's part of the kernel and have alsa-lib 1.0.7, alsa-headers 1.0.8_rc1 (I don't know if I need this), & alsa-utils 1.0.6 installed. Xmms, with the native alsa output plugin, works. Something that may be related is that if I open the kde control center, go to sound system, and click test sound, artsd crashes with sigsegv even though it's set up to use alsa natively (this used to work). Something else I recently did is switch sata controller drivers which changed 2 of my disks from hd.. to sd.., but I don't see how this could affect anything especially since I'm running a software raid on top of that so my system is still on md0.
Here's some possibly useful info:

what happens if you restart the alsasound service?
On bootup I have no /dev/dsp /dev/mixer, but from the moment I restart the alsasound daemon (/etc/init.d/alsasound restart), all the nodes come back... |

That did it. Thanks a lot :-) Do you have any idea what caused this or if there are any bugs filed anywhere about this?
I realized this may not be clear. Restarting alsasound causes the devices to be created, but like yours, they disappear again when I reboot and I have to do it again. |

well... as I stated before, I have the exact same problem, and I don't know what causes it...
I've manually added the modules to load to /etc/modules.autoload.d/kernel-2.6, but that still didn't bring a solution...
It sucks bigtime, cause everytime I reboot, I have to restart the alsasound daemon... 
maybe someone else has a solution for this... |

Here is another gentoo user who has this damn problem. I need to restart alsasound everytime I reboot to get /dev/dsp back and for me this happened after an recent update, too...
The init script for alsa belongs to alsa-utils, which I did not upgrade ( 1.0.6 ). As a conclusion either the alsa-script was always buggy and its bug is now triggered by the new alsa-driver in the kernel - or its a bug in the new alsa-driver used in linux 2.6.10. |

I suppose the problem belongs to 2.6.10. I have the same problem and I had only upgraded the kernel version.
using restarting alsa the devices appears, but then I get strange problems with volume control of gnome.
I searched in gentoo bugs but nothing found... |

|

I had the same problem after upgrading to vanilla 2.6.10-r1 from 2.6.8.1. I fixed it by compiling sound support into the kernel rather than as a module
| Code: | | <*> Sound card support |
and disabling alsa and oss in the kernel. Then I reemerged alsa-driver and alsa-utils. Now /dev/dsp and /dev/mixer as well as everything in /dev/sound are created on startup.
I'm just guessing here, but I think the problem was that the soundcore module doesn't get initialized in time when the alsa modules are loaded. That's why if you restart alsasound it works. But if we build sound into the kernel, then it finishes initializing before alsa is loaded. Anyway, I'd like to know if this fix works for anybody else. Also, it shouldn't matter whether you're using the kernel's builtin alsa support or alsa-driver but I haven't tested the in-kernel option yet. |

that could very well be the solution for this annoying problem...
I don't have alsa in the kernel either, but I do have the soundcore as a module...
I'll rebuild my kernel, and update this post if it works
thanks for pointing this out Peripatetic!
EDIT: well, you were right!!! thanks a lot for bringing this to my attention... everything works great now! |

| An alternate solution would be to upgrade udev to udev-050. That solved the problem for me. |

I haven't had luck with any of these in getting /dev/dsp reinitialized.
running linux-2.6.17-gentoo-r8 with udev-087-r1. Sound card support compiled in, as well as disabled oss/alsa in kernel. All driver configuration has occured externally.
I let alsaconf do it's magic in detecting the card, as wel as attempted restarting service upon load. I even created aliases linking to /dev/dsp and have had no luck having them regenerated. I'm to the point of attempting to create them manually. |

Issue was PEBKAC, I wasn't expressly compiling with OSS support. |

oss support compiled as a module and media-libs/alsa-oss is how I fixed it.

hi,i don't know where to start from,i hope someone will help me.after an update thast i did yesterday when i log in i get a crash message about artsd like this
| Quote: | | The application Soundserver (artsd) crashed and caused the signal 6(SIGABRT) |
the backtrace is this :

This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

i have the exact same problem, but i can't tell what caused it. i use emu10k1 and the ouput of `/etc/init.d/alsasound start` should be fine:
| Code: | * Loading ALSA modules ...
* Loading: snd-card-0 ... [ ok ]
* Loading: snd-seq-oss ... [ ok ]
* Loading: snd-pcm-oss ... [ ok ]
* Loading: snd-emu10k1-synth ... [ ok ]
* Loading: snd-seq-midi ... [ ok ]
* Restoring Mixer Levels ... [ ok ] |
if i don't start alsasound, playing audio files with mplayer works fine, but i have no /dev/mixer or /dev/dsp |

Maybe i didn't mention that everything was working perfect and arts and amarok crashed after my latest upgrade.Many people around the internet have the same with alsa after some upgrade.I found one library that is broken and i will try to fix it and post again |
