Hello,
Perhaps this should go to mobile, but I'm not sure.
I'm running FreeBSD 4.1-STABLE (of 14/08/2000) on IBM ThinkPad
600E .
I have the following lines in the configuration file:
options PNPBIOS
device pcm
and the weird thing is that the device works randomly, e.g.
after some boot I see:
pcm0: <CS461x PCM Audio> at irq 11 (1p/1r channels duplex)
pcm1: <CS423x-PCI> at io 0x530 irq 5 drq 1:0 (1p/1r channels duplex)
and both don't work.
pcm1: play interrupt timeout, channel dead
pcm0: play interrupt timeout, channel dead
Sometimes I see pcm0 (only) on io 0x530 and it WORKS,
sometimes I see pcm1 (only) on io 0x530 and it WORKS too.
For the two latter things I created a script which does:
cd /dev; sh MAKEDEV snd`cat /dev/sndstat | grep 0x530 | awk '{print
substr($1,4,1)}'`
But when it doesn't work, I need to power-off the computer and then hope that on
this boot it will work.
Here's dmesg log which is relevant to pcm (this time, it DOESN'T work):
pcm0: <CS461x PCM Audio> on csa0
pcm0: ac97 codec reports dac not ready
pcm1: <CS423x-PCI> at port 0x530-0x537,0x388-0x38b,0x220-0x233 irq 5 drq 1,0 on
isa0
This is from the boot it DID work (as pcm1):
pcm0: <CS461x PCM Audio> on csa0
pcm0: ac97 codec invalid or not present (id == 0)
device_probe_and_attach: pcm0 attach returned 6
pcm1: <CS423x-PCI> at port 0x530-0x537,0x388-0x38b,0x220-0x233 irq 5 drq 1,0 on
isa0
This random nature is very confusing, as I'm afraid to experiment with other
options.
Please advise,
