Hi again - First of all, many, _many_ thanks to all HDSP coders and contributers, I've been using my multiface regularly for over a week and am enormously impressed by the quality of tools available for this card...and I can't imagine how ever I did without the matrix mixer ;) Regarding the HDSP multiface and HDSPconf: As I understand it, this card has two "speeds", single and double corresponding to approx '48k and under' and 'over 48k' respectively. I'm interested in 44.1K and 96K. So: - Shouldn't the sampling rate (and "speed") be switching automatically based on the rate of whatever file is being played (or based on whatever rate a new JACK server requests, etc), am I missing something? I've been setting the rate manually with HDSPconf or via my play script with amixer (numid 11). - Perhaps related, should I be able to set the sample clock source to "AutoSync" (it won't stay toggled) even without external digital connections? Is this lack of "Internal" AutoSync what's breaking sampling rate switching/handling as mentioned above? Happy Holidays . Kevin
