M-audio Firewire 410 On A 9.2.2 Pismo, Getting a cyclic amplitude noise Options

[kactus]

Hi all,

Hope you can help me.

I´ve tried several times to run a M-audio Firewire 410 interface on a pismo 500mhz with macOS 9.2.2,
and I get a cyclic noise when playing back sounds whatever the aplication is, (logic 4.8, Peak 2.6, spark 1.5
or Max/MSP 4). The noise looks like a amplitude problem but repeats itself with a 2 or 3 second interval.
I tried several latency buffers from 32 to 1024 samples with several sampling rates like 44.1, 48 or 96 in both
16 and 24 bit word, without any result and not avoiding the noise...

Does anyone have a similar problem? Any clues?

The same interface runs quite invisible on a powerbook g4/867...

M-audio can not check the problem...

thanks in advance,
kactus

hmm I guess the 867 was OS X? If so then all you can say is that the 410 hardware is ok. It still leaves either a software issue or a pismo fault.

Did you try the second firewire port on your pismo?
Is it ok through Pismo speakers, Logic using Mac audio driver.

You need to find another OS9 machine to try it on unless someone here can provide those results.
