Yes, it was me :-) Thanx for answering!

The problem here is - my BIOS for the Toshiba Tecra (v5.60 - I even upgraded
to this one, former 5.50) does not have a switch for turning PNP on/off :-(
All I can set with sound is:
WSS I/O Adress 534H
SBPro I/O Adress 220H
Synthesizer I/O Adress 388H
WSS & SBPro IRQ Level IRQ5
WSS & SBPro DMA
Playback = Channel 1
Recored = Channel 0
Control I/O Adress 120H
My laptop uses the CS4232 chip.

exactly like mine:
sb0 at isa0 port 0x220-0x237 irq 5 drq 1: dsp v3.02
with
sb0 at isa? port 0x220 irq 5 drq 1 # SoundBlaster
enabled in the kernel config file.

I stil got nothing else than the first second repeated until the file
is at its end. Strange enough, that when I play an animation with xanim, I can
fade the sound from loud to off, but always repeating the first bits :-(
I even tryed to turn "sb0 at isa?" off and enable the PnP support with
two possible numbers I got from Mike Long in /src/sys/dev/isapnp/sb_isapnp.c:
PNP ID for the part as a whole is "CSC4232"
PNP ID for the SBPro logical device is "PNPB002"
but I did not even get a message from isapnp. Even not with DEBUG_ISAPNP
enabled.
Maybe it is related that I have the atapi and pcmcia patches installed to
current?
Thanx for any hint to get audio working...
