Hi. Can a sound card such as the SoundBlaster 64 Gold be used as an inexpensive DAC? My goal would be to vary a voltage source under computer control. I have tried to send a string of values into /dev/audio and watch the response on an o-scope. I only seem to see changes when the values going into /dev/audio are changing. This makes me question my understanding of a sound card. Anyone have experience in this area? Thanks. --- Kent Vander Velden kent@iastate.edu To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
