Hi,
I am on Fedora 9, pulseaudio 0.9.10, linux 2.6.25.4
I've recompiled my own kernel from the sources and pulseaudio does not start.
Using the Fedora official kernel it works.
I've used the config from Fedora and it works (without all the patches), but there are too many
different options (wrt my config) to find the culprit.
This is the error message:
E: alsa-util.c: Error opening PCM device hw:0: No such file or directory
E: module.c: Failed to load module "module-alsa-sink" (argument: "device_id=0
sink_name=alsa_output.pci_8086_24c5_sound_card_0_alsa_playback_0"): initialization failed.
I've compared the strace of a working and failing run and the difference seems to be here:
Working
open("/dev/snd/controlC0", O_RDONLY) = 15
Not Working
open("/dev/snd/controlC0", O_RDONLY) = -1 EACCES (Permission denied)
I've compared the 2 directories /dev/snd and there is a small difference:

2 differences:
1) the minors have changed
2) what is the "+" after the permissions?
Anybody has a clue?
