Hi!
Please, recomend a sound card with the best SPDIF out. Must be supported:
- ALSA support,
- stereo playing back,
- up to 96KHz sample rate,
- up to 24 bit depth,
- coaxial SPDIF out (optical is optional),
- of course, without resampling,
- (most important) minimal jitter.
Assumed using is a stereo playing back with an external DAC.
Preferably, without an overloading (MIDI, multiple analog ins/outs and so on).
Moreover, ADC/DAC may be absent at all :-) USB (rather PCI) variants are
acceptable also.
Thanks in advance!

Which sample rates do you need to be able to play without software
resampling?
- (most important) minimal jitter.
This should be a function of the host OS and driver, not the device
right?

Rates are: 44100, 48000, 96000.
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.
Of course, all these is costly, but without DAC/ADC, MIDI and such
it may be suitable.

Forget about USB, unless you're forced to e.g. on a laptop.
For PCI cards, the M-Audio Delta cards are very good and not too
expensive. If you only need stereo, then the M-Audio Delta Audiophile
PCI is a very good and popular choice.

Frank,
Thanks! And which Audiophile do you mean? 2496 or 192?

2496, the AP192 is hardly supported at all due to lack of help from
M-Audio.

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:

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 :-/
