Thank you for your reply. I contacted RME support, they are willing to help, but I got no response from the Linux ALSA developers. I do not know if my card is ok, so if your driver shouldn't do the job, it also could be, that the card is broken, but I don't think so. On Linux the mixer does show the audio signal for all ADAT inputs, but it's impossible to rout the IOs to jack capture and playback ports. In case of doubt I need to get Windows on my machine or I have to mount the card to somebody's Windows machine. OT: Btw. I didn't know about quad speed devices, I only know that some ADAT devices can be used with 96KHz too. For professional audio quality nothing more than 48 KHz is needed, just some less good converters do sound better at higher sample rates, it's not because a higher sample rate does provide something, that can't be already provided at 48 KHz. IMO people shouldn't hunt for higher sample rates, but good converters and discrete analog IO circuits. YMMV! Regards, Ralf
