my mailbox)
ohci_hcd is there is you specify usb in the list of priorities rtirq
needs to raise. And nvidia is there probably because it shares an
interrupt with a real soundcard. Rtirq does not raise the priority of
only the soundcard, but everything that uses the interrupt that the
soundcard uses.
AFAIK it is not possible (or simple) to raise _just_ the soundcard as
it
is impossible to know which irq process corresponds to a soundcard
(and
which one does not). That is because the labeling of the irq process
names in the ps listing is arbitrary. At least that is what I
remember
seeing last I looked at this issue. You can of course manually lower
the
priorities of non-soundcard irq processes with chrt.

The IRQ issue also is there for e.g. my AVLinux install, but there it
anyway is possible to get the wanted prio order:

Thank you, later today or tomorrow, I'll take a look at this.
spinymouse@precise:~$ chrt --help

Is it really necessary to send an email to this list with the output
of "chrt --help" as the main body of the message?

I'll test the vesa driver ASAP. It wont fit to my needs regarding to the
tube monitor resolution, but perhaps audio won't fight the graphics
anymore.
Btw. I do have the money to buy a new mobo. IMO it's unethical to
through away my mobo and to get a new one, anyway, I flirt with a sandy
bridge thingy.

Hello Ralf,
Is it ok for you to stop replying to yourself? And if you reply, could
that reply be on the mail you really want to reply to? Otherwise the
thread becomes really illegible. Thanks.
Best,
Jeremy

Well, just fyi, rtirq is more or less a sophisticated frontend for chrt.
