Don't forget that there are four channels on the Maestro3 than can be :used for playback. /dev/dsp is actaully /dev/dsp0.0, and there is dsp0.1, :dsp0.2, and dsp0.3 (along with the dspW variants, etc). I don't think that :4.x makes these extra /dev nodes by default, so you will have to run :/dev/MAKEDEV. Yes, the driver will not unload until all channels have been :closed. So if you get in a pinch, use another channel. Looking at MAKEDEV, it doesn't appear to know anything about dsp beyond dspX. Here's a directory listing. 9:36am ghast /dev %ls -la dsp* lrwxrwxrwx 1 root wheel 4 Jun 4 09:34 dsp -> dsp0 crw-rw-rw- 1 root wheel 30, 3 Jun 4 09:34 dsp0 lrwxrwxrwx 1 root wheel 5 Jun 4 09:34 dspW -> dspW0 crw-rw-rw- 1 root wheel 30, 5 Jun 4 09:34 dspW0 I used 'MAKEDEV snd0' just as I always have to create the device node entries. There's no dsp manpage entry, and I'm not going to try and guess at major/minor numbers to throw at mknod by hand. I don't know where the source lists the maj/min numbers, and couldn't find them in dsp.[c|h] or in sound.h. Is this documented anywhere? :2. There seems to be an issue where if 'device pcm' is compiled into the :kernel and you load snd_maestro3, it will erroneously load snd_pcm. Once :this has happened, any attempts to unload snd_pcm will result in a panic. :The workaround is to remove 'device pcm' from your kernel. Removed the pcm entry from the config file, did a config -r, and rebuilt. The kernel still loads snd_pcm, but I can unload it without a panic now. I cannot begin to guess what the difference is.
