I posted the contents of the logfile in my last mail. Here it is
again:

The output in the file works. When I try to replay it with ac3dec without
a parameter than it have some CRC failures but it comes to the end.

htpc:/ # /usr/bin/ac3dec /tmp/ac3file
5.1 Mode 48.0 KHz 448 kbps Complete Main Audio Service
** CRC failed - skipping frame **
...
** CRC failed - skipping frame **

But with -C or -P the process runs in a neverending loop.
An abort with Ctrl+C doesn't work. Following error message
is displayed:

htpc:/ # /usr/bin/ac3dec /tmp/ac3file -C

In /var/log/messages are no entries from ac3dec.
