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

Reminds me some annoyance by hard drive accesses… Do you use an external Hard Drive too ? Else, maybe some network activity… no other idea

No, I dont use a external hard drive, but now that you mention, the internal HD
does a similar noise rotating...
Could it be the internal HD?
thanks,
Kactus
