I've tryied with other external speaker and with other releases of alsa-driver, but there's no difference. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- has duplicate 0000664 ac97_quirk with SIS 7012 [ALC202] don't... ====================================================================== ---------------------------------------------------------------------- dale - 06-22-05 19:50 ---------------------------------------------------------------------- Hi wenton, do you have any more information on your configuration? I only have /dev/dsp, not /dev/dsp0 /dev/dsp1 etc. I am using UDEV if it helps. So are you saying you have actually managed to get the headphone port to work with this configuration? Many Thanks, Dale ---------------------------------------------------------------------- wenton - 06-24-05 08:54 ---------------------------------------------------------------------- Hi Dale, Well, first off, if I understand correctly, (someone else please verify/correct me), UDEV only manages hotplug devices, but I did find an excerpt from 'man udev' that might be useful: # sound card with PCI bus id 00:0b.0 to be called dsp BUS="pci", ID="00:0b.0", NAME="dsp" but I have to admit, I don't know enough about udev to know how to use that information. There were a few other things in that man page that suggested that various device files are managed by udev, so that might be why your /dev/dsp[0-3] could be missing. (I don't want to polute things by posting it into here.) As for my own configuration, on a Compaq M2010, I am using Slackware 10.0 which comes with ALSA1.0.5a. I simply allowed alsaconf to detect and configure everything on it's own. When I do 'ls -l /proc/asound' I find: I82801DBICH4 -> card1 Modem -> card0 (and other stuff) So at least I can verify what I thought earlier, about ALSA detecting the modem as card0 and the audio ports as card1. Also, looking at /proc/asound/cards tells me about the same thing. Another thought, and again I'm looking for someone to verify/correct me, I believe the /dev/dsp? files are OSS-related, and if you have OSS compatibility turned off, that might explain why those files aren't on your system. My laptop only has a mic input and lineout/headphone out, but it does seem to be working just fine. I think ALSA only wants to set mixer settings specifically for /dev/dsp0 (somewhere in rc.alsa?) so I have to manually set my mixer settings every reboot, so I added that to my rc.local, but at least it does work.
