View Full Version : Stopped Working

Power to my apartment went out abruptly, and now my Squeezebox Duet stopped functioning. I believe it's a networking issue, not a hardware failure issue. I suspect getting it to work the first time might have been more luck than anything else... The problem is that I don't *really* understand how this thing works.

The receiver is hooked up to my local LAN's switch via ethernet. The light on the switch, I believe, is low white, indicating "receiver is on but music is not playing". I'm not 100% sure of the color, so I'm attaching a picture. My DSL modem appears to recognize the receiver:



Device: Squeezebox
IP Address: 192.168.1.45
Subnet Mask: 255.255.255.0
MAC Address: 00:04:20:17:18:cc
Network Connection: Ethernet
Lease Type: Dynamic

And I can even ping the receiver. As far as I can tell, the receiver is as healthy as can be.

On to the remote. I didn't realize this before, but apparently, the remote is also assigned its own IP address by my DSL modem:



Device: SqueezeboxController
IP Address: 192.168.1.43
Subnet Mask: 255.255.255.0
MAC Address: 00:04:20:1b:23:2d
Network Connection: Ethernet
Lease Type: Dynamic

I can ping the remote as well.

So here's the problem.


On the remote I press Home | Settings | Music Source

I see 3 things: "SqueezeNetwork", "lucifer", and "Other Server". Lucifer is the name of my WinXP system that runs the SC. Lucifer has static IP and is not running any firewall or antivirus at present.

I'm not sure what the "SqueezeNetwork" option is - maybe it's fore wireless setups? So I choose "lucifer", and after a little while the remote tells me "Could not connect Squeezebox 1718cc to lucifer".

So I go back and click "Other Server" and enter Lucifer's IP address (192.168.0.3). It dumps me back to the "Music Source" menu. This time I see "192.168.1.3", "SqueezeNetwork", and "Other Server". I try to push "192.168.1.3", but the remote makes an audible "click" sound and doesn't do anything.


From the SC:


Version: 7.3.3 - 27044 @ Mon Jun 15 15:14:08 PDT 2009
Hostname: lucifer
Server IP Address: 192.168.1.3
Server HTTP Port Number: 9000
Total Players Recognized: 1


I'm stumped. It appears that both the receiver, remote, and SC are healthy. Yet the receiver can't connect to the music source. I can see communication between lucifer and the remote control:

However, I see no traffic on TCP/3483 or TCP/9000. Lucifer may be WinXP, but satan is Linux, so I have Linux networking tools at my disposal.

Can some kind soul help me figure out what's wrong? Aside from being bummed not to have my music, I'm very curious what the problem could be.

Many thanks!
Pete

"Total Players Recognized: 1"

This suggest that SC sees the receiver, can you play music with web interface,
open squeezecenter and play some music from there ?

This would rule out the Reciever part as faulty.

Then it's "only" the matter of getting the controller on the right track again.

For the most part it works like this, the controller(s) ir-remotes web-UI whatever talks squeezecenter, squeezecenter talks to the players.

So if the controller is unresponsive does not automatically means that the reciever is not working, sadly controller is the most sensitive part.


Edit: is port 3483 open on UDP too ? it should be, but you say you have no firewall ?

Seems to me that the LED colour is showing bright white, this means that the receiver is playing. Are the audio cables to your amp/powered speakers sound?
