Way back in FreeBSD 2.2.5-RELEASE, my gravis ultrasound worked, with the following exception. Though the sound was excellent, I would get a constant stream of kernel messages saying "channel X busy". Starting with some change made to the kernel sources back in 2.2.5-Stable and on, I can no longer even get sound from the sound card. Attached are the dmesg, bootup msgs, and kernel configuration. I did as LINT said, changing the #defines in sound_config.h. I even tried passing the values for the read and write channels as well as the IRQ into kernel options. Any help would really be appreciated. ***************************************************** dmesg (after trying to play an mp3): . . . isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 busy isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 busy isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 not acquired isa_dmastart: channel 5 busy . . . ****************************************************** kernel configuration: machine "i386" cpu "I586_CPU" ident "EFFICIENT" maxusers 10 options INET #InterNETworking options FFS #Berkeley Fast Filesystem options "COMPAT_43" #Compatible with BSD 4.3 [KEEP THIS!] options BOUNCE_BUFFERS #options FAILSAFE #Be conservative options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor options "NO_F00F_HACK" options "NSWAPDEV=3" options "CLK_USE_I586_CALIBRATION" options COMPAT_LINUX config kernel root on wd0 controller isa0 controller fdc0 at isa? port "IO_FD1" bio irq 6 drq 2 vector fdintr disk fd0 at fdc0 drive 0 options "CMD640" # work around CMD640 chip deficiency controller wdc0 at isa? port "IO_WD1" bio irq 14 vector wdintr disk wd0 at wdc0 drive 0 controller wdc1 at isa? port "IO_WD2" bio irq 15 vector wdintr disk wd2 at wdc1 drive 0 # syscons is the default console driver, resembling an SCO console device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr # Mandatory, don't remove device npx0 at isa? port "IO_NPX" flags 0x0 irq 13 vector npxintr device lpt0 at isa? port? tty irq 7 vector lptintr device psm0 at isa? port "IO_KBD" conflicts tty irq 12 vector psmintr # device sio1 at isa? port "IO_COM2" tty irq 4 vector siointr device ed0 at isa? port 0x280 net irq 3 iomem 0xd8000 vector edintr pseudo-device loop pseudo-device ether pseudo-device log pseudo-device pty 16 pseudo-device gzip # Exec gzipped a.out's # This provides support for System V shared memory. # options SYSVSHM options SYSVSEM options SYSVMSG #device pcm0 at isa? port ? tty irq 5 drq 1 flags 0x0 vector pcmintr #See also /sys/i386/conf/LINT. #To enable sound driver support, the controller sound code must be included #in your config file: # SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound # Controls all sound devices controller snd0 # Gravis UltraSound - for GUS, GUS16, GUSMAX # For cards that use 2 DMA Channels: # drq = Write DMA Channel, flags = Read DMA Channel device gus0 at isa? port 0x220 irq 5 drq 5 flags 0x1 vector gusintr # i386/isa/sound/sound_config.h.
