[linux-audio-user] RME Hammerfall 9636 - troubleshooting

Hi all, I have a fully up-to-date PlanetCCRMA FC3 machine - 700Mhz P3 with about 640MB of RAM. I bought a cheap second-hand RME Hammerfall 9636 recently, in the knowledge that it was untested. I've plugged the card in, and run alsaconf. I can start jack with qjackctl, and connect my audio applications to all of the cards inputs and outputs, and so on. I have a Behringer ADA8000 connected to the first lightpipe output. However, I'm having difficulties getting a clean output - whichever software I use... For example, when I play audio, and route it to output 1, all I can hear is some approximation of white noise, until the volume gets to somewhere near maximum - when I can hear a very distorted version of the original sound. Does this help at all? I'm *hoping* that I've just done something wrong, and that the card isn't fried. ALSA detected the card fine though, for what it's worth. Regards, Michael
