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@bootsy new]$ arecord -f dat -D spdif 909track.wav
Recording WAVE '909track.wav' : Signed 16 bit Little Endian, Rate 48000

This doesn't look ideal to me either:

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 :=(
:} Them great big cards is called "motherboards".
Does yours have any distinguishing features? ...Maybe a brand name or model
number?
Any IRQs blocked or not enabled? Can you at least reserve any of them?
Which slots are shared, do you need the SCSI? What's mapped to 3, 5 and 7,
etc? Why is nothing mapped to 3, 5 or 7?
Yeah I do need the scsi because my only hard drive is plugged into it ;=)
I have no idea why nothing is mapped to 3, 5, or 7. I don't think any
IRQs are blocked or not enabled, but I've never done any fiddling with
IRQs before so I could be missing something. I don't remember my bios
offering me the ability to change anything here... I'll have another
look next time I boot though.
Thanks,
Jordan.
