thanks eric yes, that the way i did it, from inside pwrSDR, audio option menu tab. ..oddly enough, with wireless internet working, with regular 800 uSec dpc spikes every 10 sec, if i go ahead and log on with google, I can bump audio buffers on down to 512...???...for about 15 minutes or so...then the motorboating.. as mentioned before, with wired ethernet connected, logged on or not, and no dpc spikes above 350 uSec, can only lower audio buffers to 1024... cpu utilization around 30 +/- 5 %.... am i 'beating a dead horse' trying to get audio buffers down to 256, for ultra snappy cw ?? 73, dan, w5xz

This will ensure that the application is aware of the change and makes all of the necessary changes to the DSP, Audio, etc to handle the smaller buffers.
