Linux 2.4.19 + lowlatency
Soyo TISU P-III 1.3GHz
Audiophile 2496 using RCA SPDIF
Alsa 0.9.0rc7
i followed the advice on Planet CCRMA.
i can monitor the SPDIF In. It works about 80% of the time. The
other 20% is silence and clicks. This result is in single user
mode on console. i have the card alone on IRQ 9 and nothing
else is sharing IRQ 9 (see attached lspci & dmesg output).

Turning on low-latency doesn't make any difference:
joshua at almost:~$ cat /proc/sys/kernel/lowlatency
1
(i tried the same setup on my SMP motherboard. It doesn't work
at all. 95% of the sound is lost. The Audiophile seems extremely
sensitive to hardware.)
i'm wondering if i have a defective Audiophile card? Any idea?
