Is it possible to get this AC3 audio channel on replay back to jumper J2
of the DVB card onto pin 4 aka S/PDIF connector?  Then one could connect
this to an A/V receiver or amplifier which do the decoding of such an audio
channel automatically.  With this method I'm able to hear my DTS CDs with a
normal CD player conneted with a TOS link to my A/V amplifier.
