Re: ibook2.2, sarge, kernel2.6.8 & devfsd: no sound, no cd-writing
Hi,
just in case someone has the same problems, I'll sum up what I've learned
since then:
- cd-burning as none-root is broken in kernel 2.6.8, use 2.6.7 or 2.6.9 (not
available yet)
- devfs is deprecated, use udev instead
- in 2.6.8 oss-sound is working, alsa has some issues (playing to fast, some
gaps)
- i still _believe_ that i should switch to alsa if possible
regards,
Holger
