 |
|
on kde startup I get an info:
| Quote: | Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such file or directory)
The sound server will continue, using the null output device. |
what does it mean? I tried to install alsa, but I haven't managed to do that yet :/ (in proper way I mean)
got sb live! 5.1 - alsa and emu10k1 are compiled in kernel as modules (btw - I've got no sound) |

You'll need ALSA installed and configured first. Are you following the ALSA Guide?

i tried it (and alsa howto on wiki too) but i dont get any good results on level with trying if my card's working... and I don't get that - should I install OSS first or not? when I try to open alsaplayer or aoss I get errors that plugin (?) couldn't be found
maybe instructions step-by-step may give me a reason what I did wrong? |

Is alsa one of your use flags in /etc/make.conf? If not it should be and the relevant sound apps should be recompiled (it's my understanding you can play around with OSS compatibility but I haven't done this). The other thing that seems to trip people up is to remember to unmute with amixer. The ALSA guide should be followed as a step-by-step guide, you can't skip a step. I don't use KDE but I'd imagine your error means arts (under kde-base) needs to be compiled with ALSA support. Hopefully a KDE user can confirm or deny this...

This is actually the problem which concerns and confuses me as well
There are two sets of devices being created for sound
/dev/snd - seems for native alsa devices, among them I have
controlC0 controlC1 pcmC0D0c pcmC0D0p pcmC0D1c pcmC1D0c seq timer
and
/dev/sound - which contains devices for OSS emulation, like adsp audio audio1 dsp dsp1 mixer mixer1 sequencer sequencer2
devfs creates a symlinks from /dev to /dev/sound, like /dev/dsp -> /dev/sound/dsp etc.
When I don't load OSS emulation, all this links are broken, and many utilities complain
(including the ones I thought should work with pure ALSA system) |
