Trying to get the sound to work on my Compaq Presario M2000. With version
5.4 everything worked fine except sound and ACPI. After looking at
http://people.freebsd.org/~ariff/ I had the impression that I could get
the sound to work by applying the provided patch, but that it should work
without extra tricks if I upgraded to version 6 of the kernel. Well, I
didn't succeed with the patch, but since I didn't think sound so important
I let it be for the moment.
Later I decided to upgrade anyway, and now I return to the sound problem.
Now uname -a gives:
FreeBSD possession 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #0: Thu Mar 9
20:27:08 CET 2006 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/KERNEL2
i386
Here I must ask what PRERELEASE actually means. It's not in the handbook
as far as I can see.
This is the message I get when starting KDE, unchanged since before the
kernel upgrade:
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such file or directory)
The sound server will continue, using the null output device.
When I do kldload snd_driver the following message appears on the console:
pcm0: <ATI IXP 400> mem 0xc0003400-0xc00034ff irq 17 at device 20.5 on pci0
pcm0: WARNING: timeout during codec detection; codecs might be present but
haven't interrupted
What does this mean? It seems to find the right module, but it still
doesn't work and I don't understand the message. Now, according to
instructions I also run the following:
possession# pciconf -lv | grep -B 4 audio
subclass = PCI-PCI
[EMAIL PROTECTED]:20:5: class=0x040100 card=0x3091103c chip=0x43701002 rev=0x02

class = multimedia
subclass = audio
possession# sysctl hw.snd.verbose=2
hw.snd.verbose: 1 -> 2
possession# cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
possession# sysctl hw.snd
hw.snd.report_soft_formats: 1
hw.snd.targetirqrate: 32
hw.snd.verbose: 2
hw.snd.maxautovchans: 0
hw.snd.unit: 0
possession# /usr/sbin/mixer
mixer: /dev/mixer: No such file or directory
And by the way I got another problem as well. After upgrading the kernel I
had a strange crash where the screen turned white (actually grey with some
vague patterns) and I could do nothing except turning off the power. Could
not contact the computer from outside, it was really dead. It only
happened once, but I would like to know why -- or if anyone else has seen
a similar behaviour.
Lots of questionmarks here. I will greatly appreciate to get some of them
straightened out.
