I had encountered the problem in 4.2-S on earlier dates, but recently
(this morning) re-synced my sources & did the build{world,kernel},
install{kernel,world}, mergemaster, reboot drill.
I am using Katsurajima Naoto's ich.c driver; the machine is an IBM
Intellistation 6868-10U (600 MHz PIII); dmesg says:
pcm0: <Intel 82801AA AC'97 audio> port 0xf400-0xf43f,0xf000-0xf0ff irq 9 at devi ce 31.5 on pci0
and cat /dev/sndstat says:
FreeBSD Audio Driver (newpcm) Jan 4 2001 10:11:03
Installed devices:
pcm0: <Intel 82801AA AC'97 audio> at io 0xf000-0xf0ff, 0xf400-0xf43f irq 9 (1p/1r channels duplex)
The "festival" port works just fine, so I have significant reason to
believe that the sound hardware functions, and the driver can drive it.
After I encountered the failure, I re-built "play" with the -g flag,
re-created the problem, and gdb says:

It was around this point that I thought trying to get someone else's
assistance with the issue might be appropriate.... :-}
The machine is one I use for testing, so abusing it is not a problem.
If this should be re-directed, please let me know.
Thanks,
david
