Talking of which: Today I found an advertisement in my (physical)
mailbox for a laptop in the sub 100 Euro range. I even managed to google
out the sound chipset which is a Realtek ALC260, aka:
0000:00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High
Definition Audio Controller
The bad news: It is supported by ALSA buut .... No sound :-D
The good news: Somebody[*] figured out that the (same) chip can be
configured in several ways, and posted a patch for an HP dc7600:

(This is not the exact machine I was looking at though!)
Is this patch back in the trunk by now? Hi profiled projects like
Apache, Linux, Mozilla and also ALSA sometimes suffers from alienation
away from the grassroots :-/

Lee, sorry, didn't understand 'function
of the host OS and driver'
(probably, my English isn't perfect :-)). As I understand a problem,
for PCI case proper shielding, clean (on the card) power supply
subcircuits and good generator are useful. For USB case - all these
and syncing from *own* oscillator.
Forget about USB, unless you're forced to e.g. on a laptop.
