how do i use it. i've tried running xmms w/ nice -n-10 xmms but i still get skips (in fact maybe more than usual.
I also can run " nice -n19 emerge -u world" which does seem to be behiving nicely, but xmms isn't getting highest priority. why is that. |

What happens if you run xmms/nice at -18?

does your ide-controller share one of it's IRQs with your soundcard? (or maybe another device like gfx-card)
this looks like you're having some harware troubles, normaly xmms takes an unmeasurable amount of cpu time on a GHz class PC, so this shouldn't be the source for you skips... |

ide: 14 15 11
smpci: 10
should be fine
dmesg does list a bunch of
"cmpci: dma timed out??"
errors
is this just from moving files xmms is loking for?
i moved the mp3s to a diff hdd (for orgazination purposes) i wonder if this willl help skips. |

cat /proc/interrupts should give you the IRQs.

usually, if you lose responsiveness whe accesing hdd, it means that you don't have dma enabled for that drive.
to know what modes are supported do:
| Code: | | hdparm -i /dev/hdX or hdparm -I /dev/hdX |
to know how you are set now try:
| Code: | | hdparm /dev/hdX (hdparm -I /dev/hdX will give some of this info to) |
a quick way to go and pretty safe is:
| Code: | | hdparm d 1 /dev/hdX |
as a side note: xmms has an option to run in realtime (or is that arts?, i'm at work so i can't check)

Negative nice numbers are only for root!
Nobody want's to run xmms as root!
Try to enable DMA for your Harddisks (Kernel must support your Chipset)

I'm using ALSA so arts priority won't help.
do the hard drive parameters have to be done everythime you boot? I've already done them once and they made my drive like 10x faster when I did a speed check. |

There may be another logical explaination.
You said you were moving mp3s around between hard drives.
I don't suppose the drive you were moving from and the drive you were moving to are
on the same ide channel?
That could very easily do it - IDE is terrible at talking to >1 device per channel, especially at the same time.
