[linux-audio-user] audiophile 2496 - spdif in

[jordan muscott]

Im really sorry about the volume of nonsense here :(

Slackware 9.
PIII 866
alsa 0.9.7

Has anyone succesfully recorded via the spdif input on this card using 
arecord? I'm getting lots of 'overuns' which result in jumps when I 
playback the resulting file. I've just built a new kernel with low 
latency but this has made no difference at all. For example:

[jordan at bootsy new]$ arecord -f dat -D spdif 909track.wav           
Recording WAVE '909track.wav' : Signed 16 bit Little Endian, Rate 48000 
Hz, Stereo
overrun!!! (at least 0.090 ms long)
overrun!!! (at least 0.030 ms long)
overrun!!! (at least 0.061 ms long)
overrun!!! (at least 0.030 ms long)

This doesn't look ideal to me either:

[jordan at bootsy jordan]$ cat /proc/interrupts
           CPU0      
  0:      98023          XT-PIC  timer

If I use the nvidia drivers for my graphics card then nvidia appears on 
irq 11 as well. My bios doesn't look like it supports setting irqs, and 
I tried switching the slots that my ethernet card (eth0) and my sound 
card are plugged into but they still appear on the same irqs.

Any help or pointers would be much appreciated. Even if someone just 
sais "no, it doens't work for me either", then at least I'll know that 
I'm not the only person who has wasted money on this card :=(
