hi JackOfAll. Thanks for your input.

As you known, piCore doesn't write to the SD card (except for backup) during normal operation. SamS issue is a regular occurring problem not just a occasional glitch. Also, he is having the problem on HDMI and Analog out as well as USB. I really want to know what is causing this because it is not making sense to me and I can't reproduce it. SamS, any chance you can try a fresh install on a branded class 10 SD card?

I laugh (to myself) when my friends tell me what they have to do to make a PC and USB DAC work properly.

(Another project that may > or may not see the commercial light of day.) Good luck with your new project. Making a quality "commercial" product certainly raises the bar a level or ten. regards Greg ------------------------------------------------------------------------ Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
