You need to keep in mind that 4-pin firewire cannot supply "bus power" to the device by definition. Therefore when using a 4-pin firewire plug on the computer end you will have to supply power to the firewire device by other means. You don't mention the details of your setup, but given that your laptop has a 4 pin firewire plug it cannot supply power to your interface. Therefore if you are not delivering power explicitly to the device (via a plugpack for example) then there's no way it's going to work. Given the symptoms as described I suspect this might be the root cause of your problem. Of course if you are supplying power to the device then perhaps the cable is suspect. Regards jonathan |

Argh. I allways just press reply on these lists. What about moving ffa...@li... to the "To:" field? Well, here goes to everyone: > You need to keep in mind that 4-pin firewire cannot supply "bus power" to > the device by definition.

Sorry for not mentioning it here earlier. > You don't mention the details of your setup, but given that your laptop > has a 4 pin firewire plug it cannot supply power to your interface. > Therefore if you are not delivering power explicitly to the device (via > a plugpack for example) then there's no way it's going to work.

My system is a Dell Inspiron 9400, with ricoh firewire. It does work under windows as I mentioned. I have not tested the stability of the unit yet, as the computer with a not-broken firewire connector of course has a broken windows (bsod all the time). It does work for as long as the computer can keep running though. We have gotten all the inputs and outputs up in qjackctl after some testing, but mplayer and jack_metro seems to give no sound output. Mplayer even seems to hang. We are looking into that at the moment. Any tips on this would be helpful. -Morgan- |
