I have a SoundBlaster 16 that I am trying to get working with FreeBSD 2.1.6. I have compiled audio support into the kernel. setting the proper values in sound_config.h for interrupts, base addresses, etc. I have also added the following lines to my kernel 'config' file: device sb0 at isa? port 0x220 irq 5 conflicts drq 1 vector sbintr device sbxvi0 at isa? drq 5 device sbmidi0 at isa? port 0x330 These are the factory defaults, and the DOS utility that comes with the SoundBlaster 16 (PnP Value edition) says that the board passes all tests with flying colors. Here's what the relevant portion of the boot up message looks like: sb0 at 0x220 irq 5 drq 1 on isa sb0: <SoundBlaster 16 4.13> <No such hardware>sbxvi0 at 0x0 drq 5 on isa sbxvo0: <SoundBlaster 16 4.13> sbmidi0 at 0x330 on isa Notice: <No such hardware> Here's what cating /dev/sndstat produces: VoxWare Sound Driver:3.0-beta-950506 (Sun Feb 5 14:38:12 EST 1995 freebsd-hackers@freefall.cdrom.com) Config options: ffffffff Installed drivers: Type 2: SoundBlaster Type 6: SoundBlaster16 Type 7: SB16 MIDI Card config: SoundBlaster at 0x220 irq 5 drq 1 SoundBlaster16 at 0x0 irq 65535 drq 5 SB16 MIDI at 0x330 irq 65535 drq 4294967295 Audio devices: 0: SoundBlaster 16 4.13 Synth devices: Midi devices: 0: SoundBlaster 16 Midi Timers: 0: System Timer Mixers: Notice: the strange values on the SB16 lines and the SB16 MIDI lines. Also, seems like there should be a mixer. (I do have a /dev/mixer, however.) I get very faint audio out of a pair of headphones in this configuration. I get no microphone input, however. I have used both the vat tool and xmix and have never gotten any mic input. If I cat a file to /dev/audio, it is faint but it comes out. I have tried upgrading to the driver on Amancio Hasty's MBONE tools web page, and the audio sounds much louder (a very good thing) but mic input still doesn't work. I am unable to test the microphone input from DOS or Windows because the machine does not have DOS or Windows. Any help is appreciated. E-mail messages at mhowitt@fas.harvard.edu are best. If there is sufficient interest, I'm happy to summarize to the group. Matt Howitt mhowitt@fas.harvard.edu
