To explain a little background on this, all products since SB2 incorporate a programmable logic chip or "CPLD", something like a FPGA. The purpose of this part is to tie together the CPU with the DAC, to provide selection from multiple clock sources, and to generate the s/pdif output signal. In Transporter it additionally routes the audio signals coming in from the s/pdif receiver and provides the special functions such as word clock I/O and effects loop. This chip contains flash memory which is factory programmed, but also can be reprogrammed in the field. Changing the programming of this part is the modern equivalent of physically rewiring a bunch of 74xxx logic chips. Prior to TP FW40 we have never revised the logic programming, so this is the first time we are having to reprogram it in the field. Clearly, something is wrong with the automated reprogramming of this part which is supposed to take place at power-on, starting with FW40. Why it would sometimes work when pressing '1' but not automatically I don't yet know, but some including myself and the QA team here have not had to force it. I will look into it. I'll enter a bug for this one but please keep an eye out for anything else. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=42960 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
