Hi all,

my aim is to play files (wav/flac) with 192kHz resolution (analog 
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 
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, 
precisely" all tools could not connect to the audio device.
I get different error messages, e.g. invalid argument: SNDCTL_DSP 
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:
I used the 24bit/96kHz and 24bit/192kHz files (decode flac 2 wav).

Many Thanks!
