boy, am I starting to feel like a broken record. I just can't seem to get a handle on this sound thing for my Dell Lattitude. Current Setup: FreeBSD trurl 2.2.7-STABLE FreeBSD 2.2.7-STABLE #0: Sat Nov 28 17:38:43 MST 1998 root@trurl:/usr/src/sys/compile/TRURL i386 on a Dell Lattitude CPi >From the kernel config file: device pcm0 at isa ? port ? tty irq 5 drq 0 vector pcmintr When I check /dev/sndstat I get: FreeBSD Audio Driver (981022) Nov 28 1998 17:38:29 Installed devices: pcm0: <SoundBlaster Pro 3.2> at 0x220 irq 5 dma 0:0 The devices look like this: trurl 7 % ls -l /dev/audio* lrwxrwxrwx 1 root wheel 6 Nov 27 21:38 /dev/audio@ -> audio0 crw-rw-rw- 1 root wheel 30, 4 Nov 29 16:32 /dev/audio0 trurl 8 % ls -l /dev/dsp* lrwxrwxrwx 1 root wheel 4 Nov 27 21:38 /dev/dsp@ -> dsp0 crw-rw-rw- 1 root wheel 30, 3 Nov 28 17:16 /dev/dsp0 . . . lrwxrwxrwx 1 root wheel 5 Nov 27 21:38 /dev/dspW@ -> dspW0 crw-rw-rw- 1 root wheel 30, 5 Nov 27 21:38 /dev/dspW0 My Problem: I can't get anything to play out through /dev/audio or /dev/dsp, whenever I try and send something to /dev/audio (like a .au file) I get: Nov 29 16:47:41 trurl /kernel: timeout flushing dbuf_out, chan 0 cnt 0x3dd flags 0x00000441 in /var/log/messages. and when I run anything that uses the dsp I get the following: Message from syslogd@trurl at Sun Nov 29 16:50:37 1998 ... trurl /kernel: SoundBlaster Pro 3.2>0 open: device busy As near as I can tell the condenser microphone is on and piping output to the speakers so that I can hear myself type. I have checked this by plugging in headphones and covering my ears and that is what I can hear. I can also get the mic/speakers to feedback if I turn up the volume too loud. This behaviour is not constant, it doesn't happen when the machine is booted under NT and it doesn't start until I see the pcm0 device detected in the boot sequence. So, either I have something set wrong in the BIOS, but I don't think I do. Or I have something accessing the devices and not allowing other applications to use the mic or the speakers. Does anyone know how I might check to see what I might have that could be doing this? Are there known applications that might cause this kind of trouble? I really would like to get SpeakFreely up and working and I would like to be able to use sound out for things like music and sound effects. Any insight on this would be appreciated. Thanks Colin E.
