Udev and Alsa

Hi, I migrated from devfs to udev and everything works fine, except alsa. everytime I boot into my system, no soundcard can be found. After I run 'sudo /sbin/udevstart' and unute master and pcm it works fine.
Is there a way to avoid this?

Re: Udev and Alsa

If udev is already in rc.conf daemons it should work- with the exheption of a few cards which need their module plus "snd-pcm-oss" listed in the modules section.
Currently not using udev at all, since hwd (the Arch way!) gives me better (and faster) results as a hardware detection daemon... you should give it a try. I have put it in the daemons array right after syslog-ng.

Re: Udev and Alsa

udev doesnt need to be in the /etc/rc.conf daemons.

It isnt a comparable thing to hwd either, its a totally different thing. You cant run hwd instead of udev.

are you sure you arent mixing up hotplug and udev?

You are either running devfs or udev scarecrow.

Re: Udev and Alsa

I did run migrate-udev and have the right modules in my rc.conf. I'm starting hotplut (even if I don't need it, but haven't tried the udev deamon.
currently I have to run:
/sbin/udevstart
/usr/sbin/alsaconf

then the sound works, but everything else works flawlessly.

There is a third option -- static /dev. ;-)

It has nothing to do with hwd though.

Re: Udev and Alsa

The sleep in my /etc/rc.d/alsa file does not work, even running alsamixer in x does not work, I do have to use /sbin/udestart beforehand.

Re: Udev and Alsa

I just have put /sbin/udevstart after the module loading in my rc.sysinit. now everything works again.
