I just installed snd970903.tgz (which fixed the panic I reported
to you, Luigi -- thanks!), and have the same problem. I can provide a little
more information: I tried testing this by running timidity, and at
first thought it was generating no volume, but remembering your
message, I cranked the timidity volume to 200%, and turned by little
speakers all the way up, and was able to make out some sound. It
was quiet, but it sounded correct, except that it was sped up by a
factor of 3 or so (confirmed by waching the time indicator progress
in timidity).o
FYI: most of the kdump output looks like a loop of:
...
364 timidity CALL write(0x6,0xefbfd0b0,0xc)
364 timidity GIO fd 6 wrote 12 bytes
"CURT 2982 10"
364 timidity RET write 12/0xc
364 timidity CALL write(0x6,0xefbfd093,0x1)
364 timidity GIO fd 6 wrote 1 bytes
"
"
364 timidity RET write 1
364 timidity CALL ioctl(0x3,FIONREAD,0xefbfd1ac)
364 timidity RET ioctl 0
364 timidity CALL write(0x4,0x11558,0x2000)
364 timidity GIO fd 4 wrote 8192 bytes
"[8192 bytes of raw music data]"
364 timidity RET write 8192/0x2000
...
However, it starts by opening /dev/dspW (which I have soft-linked
to dspW1):
...
364 timidity CALL open(0xaa60,0x6,0x1)
364 timidity NAMI "/dev/dspW"
364 timidity RET open 4
364 timidity CALL ioctl(0x4,0xc0045005 ,0xefbfd664)
364 timidity RET ioctl 0
364 timidity CALL ioctl(0x4,0xc0045003 ,0xefbfd664)
364 timidity RET ioctl 0
364 timidity CALL ioctl(0x4,0xc0045002 ,0xefbfd664)
364 timidity RET ioctl 0
...
364 timidity CALL ioctl(0x4,0xc004500a ,0xefbfd664)
364 timidity RET ioctl 0
...
These are the only ioctl's on fd 4 before the writes.
Also, when timidity starts up (before it plays anything), it says:
Output rate adjusted to 21739 Hz
I don't know if this is relevant. I hope the information helps.
