[LAU] RME HDSP 9632 - playing @ 192kHz sample rate ?

Hi all, my aim is to play files (wav/flac) with 192kHz resolution (analog output). The HDSP 9632 works fine under windows with all sample rates, but I have trouble to get the beast fully running under linux (Suse11.1 - kernel 2.6.27). I compiled latest alsa drivers (1.0.19) and all the hdsp tools (hdsploader, hdspconfig & hdspmixer) are working (I tried firmware 153 and 154, both are working). Up to 96kHz everything (various audio player/streamer xine, mplayer, xmms, baudline...) works nicely. If I set the sample clock to more than 128kHz no output is available, "more precisely" all tools could not connect to the audio device. I get different error messages, e.g. invalid argument: SNDCTL_DSP _Channels, _SETFMT, _SPEED. If I set the clock back to 96kHz everything works again. Someone out there, who solved the problem? Maybe I missed just a minor detail. BTW: The files I used for testing are available here: http://www.linnrecords.com/linn-downloads-testfiles.aspx I used the 24bit/96kHz and 24bit/192kHz files (decode flac 2 wav). Many Thanks! Daniel
