Debugging why my squeezeboxserver (version 7.4 under Ubuntu 9.04) can't find my SliMP3 player.

The Squeezeboxserver perl stuff seems to be installed under /usr/share/perl/Slim.

I can see with tcpdump that the player is broadcasting, but the perl squeezeboxserver process doesn't seem to be listening.

Debugging the server with:

perl -d -w /usr/sbin/squeezeboxserver --prefsdir /var/lib/squeezeboxserver/prefs --logdir /var/log/squeezeboxserver/ --cachedir /var/lib/squeezeboxserver/cache --charset utf8 --playeraddr 172.16.1.21 --logfile debuglog --logging debug

which invokes the perl debugger.

Didn't get anywhere. I suspect it may have to do with the two network interfaces on cumulus. Apparently UDP broadcasts only go out on one interface, which is arbitrary unless the server binds to a particular address. That's why I tried the playeraddr command above, which actually helped move the broadcast to the right interface, but that wasn't enough.

The key thing seems to be that although the server is listening to UDP on port 3483 (according to netstat -l), the process isn't receiving or selecting on that socket.

Reinstalling didn't help. Disabled most plugins.

Did a lot of debugging, and playing around with the firewall. After removing the -playeraddr argument to squeezeboxserver, it found the SliMP3. May have been a firewall issue with broadcast addresses?

Problems which have a combination of causes can be so hard to track down...

Played around with Squeezeboxserver Music server on the new server.

Had some problems getting Swedish radio P1 to stream properly (it's in WMA format), worked after installing AlienBBC plugin, mplayer and lame, and specifying mms://wm-live.sr.se/sr-p1-high as the URL. Not sure what did it. Also added the following lines to /etc/squeezeboxserver/convert.conf:

wma wav * *
[mplayer] -really-quiet -vc null -vo null -cache 64 -af volume=0,resample=44100:0:1,channels=2 -ao pcm:nowaveheader:file=/dev/fd/4 $FILE$ 4>&1 1>/dev/null

wma mp3 * *
[mplayer] -really-quiet -vc null -vo null -cache 64 -af volume=0,resample=44100:0:1,channels=2 -ao pcm:nowaveheader:file=/dev/fd/4 $FILE$ 4>&1 1>/dev/null | [lame] --silent -q $QUALITY$ $RESAMPLE$ -v $BITRATE$ - -

Also downloaded Squeezeslave (from http://downloads.sourceforge.net/project/softsqueeze/squeezeslave/squeezeslave-0.9/squeezeslave-0.9-65-lnx26-alsa-display-i686.tar.gz?use_mirror=sunet). This is a command line software emulation of a Slim Devices music player. I intend to use it to play music in my living room, and control it from the web interface.

Did:

sudo cp squeezeslave /usr/local/bin

Created a startup script by modifying the one for mydns.

Installed it with:

update-rc.d squeezeslave defaults

Also made symbolic links from /media/music to my music library.
