Just read through the thread again. It isn't clear what *kind* of sound the |
| 18 |
original poster Antoine meant. |

There is a big difference between playing sound files residing on your |
| 21 |
harddisk and playing CDs in your CD-ROM. For the latter, you don't really |
| 22 |
need access to those audio devices but to the CD-ROM because a CD player like |
| 23 |
kscd only sends commands to it and receives responses from it. The CD-ROM |
| 24 |
then sends the audio stream directly to your soundcard; it isn't really going |
| 25 |
through your CPU. |

uwe@uwix ~ $ ls -l /dev/hdd |

As you can see, the CD-ROm isn't in the audio but in the cdrom group. So if |
| 33 |
your problem is with CDs add your users to group cdrom. |
| 34 |
|
| 35 |
If that isn't your problem, play with the options under Control Center -> |
| 36 |
Sound & Multimedia -> Sound System -> Hardware -> Select the audio device. |

I used to have it set to Autodetect and no OSS support in the kernel. That |
| 39 |
worked. All of a sudden - probably after the update to KDE 3.5.1, but I am |
| 40 |
not completely sure here - that stopped working. Setting the "audio device" |
| 41 |
to ALSA explicitly didn't work either. Now I need the OSS emulation in my |
| 42 |
kernel and "audio device" set to OSS explicitly. |
