Hello again,
|
|
|
|
Playing with a SB Vibra 16x soundcard we found it very difficult
|
|
to setup because the kernel reported a lot of DMA errors and wouldn't
|
|
simply play any sound.
|
|
A good starting point is that the vibra16x chip full-duplex facility
|
|
is neither still exploited by the sb driver found in the linux kernel
|
|
(tried it with a 2.2.2-ac7), nor in the commercial OSS package (it reports
|
|
it as half-duplex soundcard). Oh, I almost forgot, the RedHat sndconfig
|
|
failed detecting it ;)
|
|
So, the big problem still remains, because the sb module wants a
|
|
8-bit and a 16-bit dma, which we could not allocate for vibra... it supports
|
|
only two 8-bit dma channels, the second one will be passed to the module
|
|
as a 16 bit channel, the kernel will yield about that but everything will
|
|
be okay, trust us.
|
|
The only inconvenient you may find is that you will have
|
|
some sound playing jitters if you have HDD dma support enabled - but this
|
|
will happen with almost all soundcards...
|
|

|
A fully working isapnp.conf is just here:

|
|
So, after a good kernel modules compilation and a 'depmod -a kernel_ver'
|
|
you may want to:
|
|
|
|
modprobe sb io=0x220 irq=5 dma=1 dma16=3
|
|
|
|
Or, take the hard way:
|
|
|
|
modprobe soundcore
|
|
modprobe sound
|
|
modprobe uart401
|
|
modprobe sb io=0x220 irq=5 dma=1 dma16=3
|
|
# do you need MIDI?
|
|
modprobe opl3=0x388
|
|
|
|
Just in case, the kernel sound support should be:
|
|
|
|
CONFIG_SOUND=m
|
|
CONFIG_SOUND_OSS=m
|
|
CONFIG_SOUND_SB=m
|
|
|
|
Enjoy your new noisy Linux box! ;)
