Hello everybody,
I have now found time to update my Slimserver to Squeezecenter. After
the update, all conversions of the standard files like APE, MPC, AAC
work fine again. Conversion of ac3 does not work yet, however. This is
the output when I use mplayer with the "-v" option to play the file as
suggested. As you can see, I have aborted playback after a few seconds
by pressing Crtl+C:

I have also taken a look at the squeezecenter logs. The interesting
lines I get when I try to play an ac3 file are these:

------------------------------------------------
So i found out that Squeezecenter uses this line for conversion:
mplayer.exe -really-quiet -af resample=44100:0:1 -ao
pcm:nowaveheader:file=#PIPE# "D:\Musiq\test.ac3" |
I tried this line to do a ac3->mp3 conversion and it failed.
mplayer.exe -really-quiet -af resample=44100:0:1 -ao
pcm:nowaveheader:file=#PIPE# "D:\Musiq\test.ac3" | lame -b 80 -
test.mp3
results in a PCM file called #PIPE# and and mp3 file that contains only
a short bleep.
Could it be that the #PIPE# construction does not work as supposed on
my system? I am running Windows XP Home SP2. Is there any way to fix it
or to use a different method to get the pcm stream piped?
Thanks for you help and happy Easter to all who celebrate it.
