Hey there collective intelligence,
I have an oppurtunity to get a really good deal on an HP NC4400, and
as I'm looking for a new laptop, I'm thinking of grabbing it. It's got
1.5 Gigs of RAM, an SATA 5400RPM hard drive, and a 2GHz Centrino Duo.
Any experiences with this sound codec? It seems to be supported with
the snd-intel-hda alsa module, but I can't find any info about
performance. I think that it's used in a lot of the newer HP and IBM
laptops. What distinguishes an "HD" sound card? One of the reasons
I've been looking to replace my current laptop is that the sound card
and video card seem to compete for control of whichever bus they're
on, so I get lots of xruns with any latency less than about 60ms.
This computer won't be used for my heavy multitrack recording
sessions, I mostly want it for synth and audio processing, maybe also
generating visuals in a live performance environment, so the low
latency is pretty critical when I've got audio running through the
computer for processing.
Thanks a lot!

If this is the same thing that comes in Macbook Pros (AFAIK it is), then it
is quite nice setup. See my earlier post about the latency on MBP...
Best wishes,
Ico

Intel HDA is a very flexible design - there's so much variation from one
machine to the next, you really need to find someone with the same
laptop who can verify that sound works.
It might be helpful to search the ALSA bug tracker for that laptop and
codec.
Ideally you would have the opportunity to test a recent live CD distro
on it before buying.
HTH,
Lee

The HDA specification is the successor of the AC'97 specification.
While AC'97 codecs are extremely cheap chips whose theoretical digital
performance numbers have no relation to their actual analog quality,
HDA codecs are extremely cheap chips whose theoretical digital
performance numbers can be even higher, but still have no relation to
their actual analog quality.
One of the reasons I've been looking to replace my
current laptop is
that the sound card and video card seem to compete for control of
whichever bus they're on, so I get lots of xruns with any latency less

PCI I/O performance depends mostly on the chipset. "Centrino" means it
has Intel which is thought to be the best in this regard.
What chipset did your old laptop have?

I've used a similar notebook with the same chipset (a Compaq built in
2002) for a number of years for light audio work (live sets with GDAM
and terminatorX), surely a cheap machine (useful as a small heater when
running at full frequency) with a crappy chassis, but reliable and with
a good driver support under Linux...

Unfortunately, I wasn't able to get the deal I was hoping for. A local
college had some extra's (They get these $2000 laptops for $800 for
all their incoming freshman) so they thought they'd be able to sell
them off, but I guess their CFO squashed the idea and said that it
violated the terms of their agreement. Looks like it's back to looking
at the full price market.
