FreeBSD Audio Driver (newpcm) May 23 2001 21:19:04
Installed devices: pcm0: <Creative CT5880-C> at io 0xdc00 irq 11 (1p/1r channels duplex)
after downgrade from 5.0-current sound stoped working, e.g. mpg123 output

i found thread from 10 May about the same problem with pcm and made
sure PnP OS is off. didn't help. what else ?
here is pciconfig -l

You might need the sbc(4) bridge driver in your kernel along with pcm for this
card to work.

/dev/dsp should be a symbolic link to dsp0. Is it? You might need to re-run
"sh MAKEDEV snd0" in /dev to make sure all the links are correct.

obviously i followed to "Sound" in Handbook where it's written
do it twice sh MAKEDEV snd0 and sh MAKEDEV snd1 so turned it to be
/dev/dsp -> /dev/dsp1, when i did sh MAKEDEV snd0 it changed to
/dev/dsp -> /dev/dsp0 so it seems to work now, no I don't need scb.
So what's wrong with Handbook ?
thank you for your responce.

It is a tad bit confusing, but it actually says to do one or the other
depending on the output of the ``cat /dev/sndstat''. Basically if
/dev/sndstat returns pcm0, do MAKEDEV snd0. If it returns pcm1, do MAKEDEV
snd1.
This just has to do with how the kernel assigns devices numbers to the sound
device. IIRC it used to be that pcm0 was reserved for ISA devices, so PCI
sound devices would be pcm1. I don't think that is true anymore though.
