Hi,
I just wanted to share this success story (kind of), especially with
Dave Phillips.
When my desktop PC (more precisely: its elitegroup mobo) suddenly ended
up in smoke on Thursday [somewhere in the middle of my diploma thesis
:-((] I had to revive my old HP Omnibook 4150.
This laptop has a "NeoMagic NM256 piece o' crap" (citing Dave[0])
soundchip which I had not been able to use with ALSA up to then.
I decided to upgrade the installed Debian version from Woody to Sarge
(current testing) and in doing so I decided to give Debian's 2.6.5-1-686
kernel image a try.
Of course, alsaconf tried to load the nm256 driver for the NeoMagic chip
which failed as expected.
As described in [1] I changed /etc/modprobe.d/sound to contain the
following lines:
----8<-----
options snd-cs4232 port=0x534 cport=0x538 mpu_port=-1 fm_port=0x388 \
irq=5 dma1=1 dma2=0 isapnp=0
alias snd-card-0 snd-cs4232
alias sound-slot-0 snd-cs4232
----8<-----
An 'update-modules' updated /lib/modules/modprobe.conf and suddenly I
was able to start ('/etc/init.d/alsasound start') and use ALSA!
Alsa-lib is version 1.0.4-1, drivers are version 1.0.4rc2.
I'm quite sure I had tried this before with a 2.4 kernel without
success.
However, I'm really pleased now (apart from the death of my desktop PC).
My digital camera (HP photosmart 715) is fully functional via USB using
gphoto2 or flphoto.
My Netgear Cardbus Ethernet adapter is recognized and automatically
configured via DHCP.
I still have to find out whether the alsa configuration survives a
suspend.
Maybe I'll also test jack performance later.
How can I find out whether my kernel has capabilities support builtin?
cat /proc/sys/kernel/??
Now I'm thinking of buying an external adapter which lets me use my
IDE harddisk (the one from the desktop computer) via USB.
(Yes, I have a backup, but it's two days old and it's not complete.)
Experiences anyone? (Slightly off-topic)
I've got to get some sleep now.
Cheers,
Jan

cat /proc/sys/kernel/lowlatency will tell whether you
have lowlatency but that's not related to
capabilities. You can look in the jack FAQ for
information on patching the kernel. It's a two line
modification. I'm not certain but seem to recall that
if the kernel does not have capabilities, then jack
will not install the jackstart script--i could be
totally wrong about this. jackstart is used in
conjunction with capabilities.

I require studio clients to have USB/Firewire drives.
Then I rsync between my array and their drive. One of
the enclosures we're using is the ME-320 Series and
it's the ME-320U2F IDE to USB2 and 1394A.
I know people are having success with 1394 storage but
I'm not one of them. I don't actually care because
USB2 is plenty good for my storage requirements and it
just works. I believe it was on the Kino site that I
read a report from someone that is successfuly using
1394B which has 800Mbps capabilities. I recently
purchased a 1394A pci card for $20.00. The card with
1394B was around $60.00.
It might be a nobrainer to put your drive into a USB
enclosure and detect partitions upon mount. You should
test with a drive that doesn't have critical data on
it so you know what to expect.
I recently needed to mount an ext2 partition that was
created on a Mac running ppc. That partition could not
be mounted in an x86 machine. In the end, I had to
mount it using a ppc box. I don't claim to be a
particularly insiteful linux administrator and don't
know what should work in theory but I know what
happened in practice.

Hi Jan:
I'm glad my article helped get your 4150 sounding, but in truth the
thanks must go to Takashi Iwai, he's the one who knew the secret facts
of the NM256. You might also like to know that there is a fix for the
NM256 in current ALSA CVS (and perhaps in the latest release?) that will
prevent it being a show-stopper whenever a live CD such as Apodio or the
AGNULA/Demudi disc recognizes the NM256 (currently they simply stop
booting as soon as they identify the NeoMagic chipset).
Btw, please let me know how well the power management works for you. I
never have got around to testing whether the suspend mode works...
Best regards,
dp
