 |
|
Righty, I am having a few problems with good ol' udev, so hopefully somebody will be able to help.
On Sunday for some reason my sound just stopped working, everything that tried to use ALSA left the following on the console:
| Code: | | ALSA lib pcm_dmix.c:802:(snd_pcm_dmix_open) unable to open slave |
I have ALSA built into my kernel (2.6.12-nitro5 / 1.0.9b), and this hasn't changed so wasn't the problem. I did a bit of digging around and found that there was no /dev/snd or /dev/sound, so I ran udevstart, but still nothing. Yet more digging showed that /dev/v4l was not being created either. In my rules I have the following:
| /etc/udev/rules.d/10-local.rules wrote: | # Optical drives
KERNEL="hdc", SYMLINK="dvd", MODE="0666"
KERNEL="hdd", SYMLINK="dvdrw", MODE="0666"
# Sound
SUBSYSTEM="sound", NAME="%k", GROUP="audio", USER="audio", MODE="0666"
# v4l
SUBSYSTEM="video4linux", NAME="%k", GROUP="video", USER="video", MODE="0666" |
| /etc/udev/rules.d/50-udev.rules wrote: | ...
# sound devices

KERNEL=="adsp[0-9]*", NAME="sound/%k", SYMLINK+="%k", GROUP="audio"

If I add the following to '10-local.rules', then /dev/v4l is created.
| Quote: | | SUBSYSTEM="video4linux", NAME="v4l/%k", GROUP="video", USER="video", MODE="0666" |
But adding similar stuff for the sound didn't work. The '50-local.rules' is the default Gentoo one, and I cannot see anything that would make anything wrong with it (after all a cazillion other people would complain if it didn't work), but the == after KERNEL looks a bit wierd, or doesn't it matter?
In summary for some reason my rules are not being processed correctly, nothing has changed since they were working that could affect them.

Alrighty, I have downgraded to udev 058 (the previous stable version), and it works fine. So it must be a problem with udev 068. Time to open a bug report....
