View Full Version : Optical Digital Output - Firmware Fix

2004-08-05, 10:51
I have the same problem - I have an auto-sensing switch that
won't recognize another digital input because the squeezebox
has monopolized the signal all to itself. The switch never unlocks
off the squeezebox when I have powered up another digital
source and start sending a signal from that.

Please file a bug for this. Yes it is a consequence of fixing the "send

zeroes between tracks".

By the way: what exactly is the undesired behavior that this causes?
Does it make your amp refuse to go into standby?
