Subject: alsa sound device configuration within udev
Date: Sun, 02 May 2004 12:38:09 +0000 [thread overview]
Message-ID: <20040502123809.GA2282@mic.paddy.net> (raw)
Hello list,
i had switched from devfs to sysfs using hotplug and udev.
Ths was necessary, because i want to identify some different usb storage devices
by plugging them into the computer.
But now my dsp and adsp devices doesnt exist under /dev or any
subdirectory. Only some pcm*, control* and timer devices can be found
within /dev/snd.
Trying to play some sound with 'mpg321 test.mp3 -a /dev/snd/pcmC0D0c'
only ends up with the error message 'libao - OSS cannot set channels to 2'
On the Internet they say that alsa isn't supportet by udev yet, but I
dont know how actual these frases are.
Is it possible to create some rules to get the old dsp and adsp devices
back?
KERNEL="dsp*", NAME="snd/%k"
or
NUMBER, BUS="pci", ID="0000:00:11.5", NAME="dsp0"
doesn't work...
Who know how to do things right?
My Kernel Version is 2.6.5 with alsa build as modules.
Thanks for your help!
Best regards.
Patrick Hornung
