Hello, I have been trying to use the hdspm driver with a recently purchased RME Madiface device. The functionality that I require is to play various files through various channels under program (script) control. I am happy to report that it *almost* works - in that I can use my simple userspace programs to play files. However, there are subtle problems - in that the external MADI A-to-D (an Euphonix 703) does not seem to lock into the sampling rate (something that works under windows). Its very close to achieving full functionality (for my needs) - but just that tiny bit away from being fully useable. Any ideas? Havent had much luck contacting RME and Winfried Ritsch (who wrote/maintains the code). Information on the the hardware and/or windows code would help to figure out how to modify the driver (which was originally written for the rme 9652/aes32 devices). Regards, D. Sen
