Screechy noise with Audiofire 8

brightonalex · Post by **brightonalex** » Sun Mar 25, 2007 7:27 pm

Hello.
There's a problem with my audiofire 8, in that it makes a screechy high pitched noise every so often.
I know it is that because:

I've played tunes (not from Ableton) through it and it still makes the noise;
It makes the noise through headphones too so its not the speakers.

Any advice? I've turned the sample rate up to maximum but it hasn't helped. Thanks!

brightonalex -

another AF8 user here, and I have to admit that I haven't had this specific issue, although once or twice i've experienced something similar.

you might try checking Activity Monitor to make sure that iCalAlarmScheduler isn't running - if it is, force quit that process. that process has caused noise issues for me in the past.

also, are you running the latest updates from Echo?

best luck -

I'm having the same issue with an audiofire 2 and I'm not having it with an audiofire 12. echo is unsure of the problem

lalo027 -

other than trying to get rid of iCalAlarmScheduler (assuming you're on a Mac), I'm not sure what else to recommend.

I'll be taking a homework break sometime this evening. I'll mess around & see if anything else might turn up.

later

Hey Thanks BDS,

I'm running win xp pro. I posted this in a more relevant forum...

I'm having these same digital latency sounding clips on win xp pro. Live 6 and 3.1.1 drivers on af2. The problem only exists when I use ASIO, but if i don't use ASIO there's a latency lag. I troubleshot with echo on the phone for hours to no avail. I thought it was a hardware issue but now i get similar problems with my echo indigo dj. My dj worked fine before i installed the af2... to make things even worse, we have an af12 in the studio which has the same drivers as the af2. my system works fine when i checked it with the af12.... ? I'm lost.

to add to this... the problem seems to only be in live. As far as i can tell I'm not experiencing this problem in Reason 3 or Sound Forge 8.

Might be a sync issue, 1s and 0s getting scrambled due to clock jitter. Try different sample rates maybe? It could also be bad cabling scrambling the signal, try a different cable. Make sure your cables are screwed in, try a different physical connection on your computer, connectors can get wonky.

Try different sample rates maybe?

+1 for Tone Deft. No homework breaks tonight, but I do recall instances where 44kHz was noise-free, while 48 & 36 were impossible to deal with. When you make a change in the Echo Console, do all of your settings automatically change to the same setting? (<= reveals a complete lack of PC knowledge)

Good luck,
BDS

God i went through everything. I think i found it... my cpu plugin buffer size was different than my latency buffer size... I'll be back in here if it persists. thanks again.

Thanks for your replies - how do I change my CPU plugin buffer size?

I went through the lessons in Ableton on audio and latency, but changing the sample rate etc only seemed to work when I wasn't using ASIO - when I switch to ASIO all that stuff is greyed out.

Last time I was using the same audio card for output (System Preferences -> Sound -> Output) as the audio card configured in Ableton with some crappy USB card I was running into tons of problems? Channel 1/2 would die everytime a program would use the soundcard at the same time as Live. Just dragging a song from iTunes was killing the audio.

If you have weird problems... trying setting the audio output in System preferences to built-in output and input and only let Ableton use your firewire or usb card.
