Hi, am new to RME and this Forum. I hope someone can help me.

A week ago, I bought a used Digiface USB and was extrem hyped to test it. But sadly I had big troubles getting it to work correctly and sadly I could not fix it at all.
I had a lot of Interfaces before, so actually it should not be a big thing for me to set this one up the right way...

So, I first installt the drivers, set the clock source to internal, cause I tested it without any digital converters, just used the headphone jack. started my daw and realised these problems I described. then I switched cables, uninstalled the software reinstalled it a few times.

Then it got weired. Til this time i had not set the WDM devices. So I did and suddenly It worked like a charm! I thought, that maybe I got these dropouts because of not using the Interface simultaneously in Windows and Ableton. But today I have the same problems again and this time I can not solve it. Maybe it was fortuity that it worked after I changed WDM settings...

to sum it up, the problem is, that my Digiface performs really bad. I have lot of dropouts even in small sessions. It is so bad, that I would say it is impossible to work with it.

Does someone have an Idea what to do next?
