Hi!
I've sent this post to comp.unix.bsd.freebsd, and I've been told that I
should report the problem to this list, so...
-------- Original Message --------
Hi folks!
I was trying to modularize the sound in my 5.0R machine, which has two
sound cards:
$ dmesg | grep pcm.:
pcm0: <VIA VT82C686A> port 0xb000-0xb003,0xb400-0xb403,0xb800-0xb8ff irq
9 at device 4.5 on pci0
pcm1: <AudioPCI ES1373-B> port 0xa000-0xa03f irq 9 at device 10.0 on pci0
In order for them to work properly as modules, the files
snd_{pcm,via82c686,es137x}.ko have to be loaded in the beginning AFAIK.
Or else they won't be recognized and will be given as PCI devices with
"no driver attached".
Well, two issues:
1)
If they aren't loaded (I forgot them on the 1st try by mistake), the
kernel panics if I try to change hw.snd.maxautovchans (that odd "bwrite:
buffer is not busy???" message again!). That shouldn't happen: if I
don't have any soundcards, this oid shouldn't _exist_ either!
2)
If they're loaded, an attempt to unload snd_via82c686.ko results in a
panic with the funny message in the subject. But: Aren't modules
supposed to be unloadable? What's the fun with modules then?
Any hints on solving this?
My attempt to load modules instead of the monolithic solution (which
always works) comes due to an odd behaviour of pcm0 (multiplexed with
hw.snd.pcm0.vchans=8) telling that some /dev/dsp{W,}0.[0-7] devices are
busy after their first usage. I wanted to address it by unloading the
affected module and loading it again, but... that'll panic the system.
Has someone had something similar?
Thanks in advance,
David.
