thougth somebody would like to know how i'm doing with my sound?
wel, still nothing but i learned again some important things
like you cannot change you're irq's in freebsd so i changed them in BIOS, deleted usb irq, changed sound irq, switched sound irq with screen, ... nothing helped.
still getting the same error msg which basicly says "request interrupt timeout, channel is dead"
and after that, the output of /dev/dsp is
"Device busy"
i tried almost everything in my kernel from option PNPBIOS (on/off),
device pcm
device pcm0
strange thing is, he finds the correct device when is cat /dev/sndstat
is there anybody who has any idea on how this could be solved?

As I can understand, to handle a irq, it is necessary to make a request_irq(). If the return value is zero, ok, no problem to handle irq.
Here is a easy example of my driver:

snd_sb8
SND_SBC(4) BSD Kernel Interfaces Manual SND_SBC(4)
NAME
snd_sbc, snd_sb16, snd_sb8 -- Creative Sound Blaster ISA and compatible bridge device driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device sound
device snd_sbc
device snd_sb16
device snd_sb8
Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
snd_sbc_load="YES"
snd_sb16_load="YES"
snd_sb8_load="YES"
Non-PnP cards require the following lines in device.hints(5):
hint.sbc.0.at="isa"
hint.sbc.0.port="0x220"
hint.sbc.0.irq="5"
hint.sbc.0.drq="1"
hint.sbc.0.flags="0x15"
DESCRIPTION
The snd_sbc bridge driver allows the generic audio driver sound(4) to attach to Creative Sound Blaster ISA (mostly SB16 or SB8, known as
SoundBlaster Pro) compatible audio cards.
The value of flags specifies the secondary DMA channel. If the secondary DMA channel is C, set the flags to (C | 0x10). For a sound card
without the secondary DMA channel, the flags should be set to zero.
HARDWARE
The snd_sbc driver supports the following sound cards:
o Avance Asound 110
o Avance Logic ALS100+
o Avance Logic ALS120
o Creative SB16
o Creative SB32
o Creative AWE64
o Creative AWE64 Gold
o Creative ViBRA16C
o Creative ViBRA16X
o ESS ES1681
o ESS ES1688
o ESS ES1868
o ESS ES1869
o ESS ES1878
o ESS ES1879
o ESS ES1888
DIAGNOSTICS
sb_dspwr(XX) timed out. A command to the DSP has timed out. Check the I/O port configuration.
bad irq XX (5/7/9/10 valid) The IRQ given to the driver is not valid.
SEE ALSO

HISTORY
