well... that *might* be a solution for the hdspmixer issue, and i will test it for that. however, note also that jack is still failing for me even if i don't use hdspmixer at all, so there's definitely something else going on (as well).

thanks again for your help... it's frustrating to have audio hardware which has been rock-solid for me for years suddenly begin to fall over like this! i can only hope a solution will emerge...

cheers!
