Well, following up to my own message...
I rebuilt a kernel using the (legacy) voxware drivers:
device snd
device css0 at isa? port 0x534 irq 5 drq 1 flags 0x08
device mpu0 at isa?
[Taken from LINT]
dmesg looks less than perfect:
css0 at port 0x534 irq 5 drq 1 flags 0x8 on isa0
snd0: <CS4232 (CS4236)>
css0: driver is using old-style compatability shims
mpu0 at port 0xffffffff on isa0
isa_compat: didn't get ports for mpu
snd0: <MPU-401 0.0 Midi interface>
WARNING: "snd" is usurping "snd"'s cdevsw[]
mpu0: driver is using old-style compatability shims
unknown0: <WSS/SB> at port 0x535-0x538,0x388-0x38b,0x220-0x22f irq 11 drq 3,0 on
isa0
unknown1: <GAME> at port 0x200-0x207 on isa0
unknown2: <CTRL> at port 0x120-0x127 on isa0
unknown: <MPU> can't assign resources
But sound is now restored. There is still a leading click when playing .au
files, but it's less pronounced, and no sound is lost.
Line-in works, too.
sndstat shows:
freebie:john>cat /dev/sndstat

[Thanks, Amancio!]
So that's it. I'll be sticking with voxware for a while.
