strange! try media player with a pair of headphones plugged in,, what is your set'up? I go out via the main outs 1 - 2 on the rear of the ul > to a mackie big knob and out > monitors.

The only problem I ever had with the interface was the setting the out's in live to channels 11/12 to get sound.

Its prob something very simple,, but I would suggest contacting motu support and see what they suggest.

yeh ive tried with headfones no luck.. i got monitors plugged into the main outs.

i think thats my only hope for now lol im gonna test it on my mates computer tomorrow

thanks for ur help

are you using a 4pin firewire or 6pin? 4pin requires the AC adapter, 6 pin does not

Mine will not even power up if i dont have the mains adapter plugged and im using a 4 pin lead, 6 pin however is fine either way

Definitely sounds like a driver problem to me. If your on XP maybe you could roll back to before you installed the drivers, then maybe get the latest drivers of the MOTU site and try installing it again?

Hey man try this.

To get sound from your windows enviroment etc (Media Player)

When motu is on, check that it displays the drivers etc in System Properties/ Hardware Tab/ Device Manager. Hopefully it is enabled.

Now, goto control panel , click sound. Make these settings.

In the audio tab/ sound playback, have selected the main outs selected not phones like most times when you turn it on it defaults to that.

then goto motu audio setup.
here under ultralite tab have these sttings.
-Main outs Vol = Main Outs
-Phones = Main Outs

this will ensure when something played back thru windows it is sent to main out's but because you have also selected the main outs to phones thru motu auido setup you also get it to come out phones 2.

hope it help dude

this way we can nail if it's an ableton prob etc.

so if you can hear stuff in a windows enviroment you know that your card is working and maybe some conflict with the ultralite driver and ableton is the case. remeber it is likely that something is interfering!

oh and what the others said is right, disable then on board sound card thru device manager.

thanks for ur help guys but nothing seems to work lol i dont even have the onboard soundcard drivers installed..

im gonna buy a new computer sometime this week instead i had this hunk of shit for 4 - 5 years now its time to upgrade.. thanks again

i dunno but that there could lie your prob for many reason's
