B and O have been a great help via a really nice chap in London from Polaris Networks. We have rebuilt the entire QNAP from the bottom up. Testing it using UPnP with Foobar2000, PS3 and all can see Twonkyserver except Beosound. I'll post up anything I find in case it helps others if / when we fix it. Currently in Denmarks corner....

Firewall disabled on the Twonky server machine?

Reboot the BS5 Encore, sometimes it doesn't pick it up.

I just got mine working this way yesterday with TwonkyMedia Server.

Try this: Install Twonky server on your laptop, plug ethernet directly into laptop from BS5e.

Disable firewall on laptop.

Assign IP manually to both machines, setting default gateway and primary DNS as the server IP (laptop IP).

Then reboot the BS5e, go to service settings and see if it can pick it up.

Then at least you can rule out the idea of the BS5e being the problem.

Thanks Ari! The QNAP does not have a friewall on it. I have checked that port 1900 is open on the QNAP and it is. If I install Twonkyserver on to my laptop the BS5 encore sees it straight away. It has been rebooted and factory defaulted numerous times but will do it after each reconfig of QNAP if thats the case.

I'll try manually assigning DNS to server ip etc. as this is a possibility which I havent tried.

Thanks again, much appreciated!

Sorry , I only saw now that you already mentioned the BS5e sees the Laptop Twonky server! No harm done though.

Yes, try setting the primary DNS to the server IP and see if that helps. Some extra guidance for the BS5 ;)

Just got a loan beosound and it doesnt see it either so have ruled that out. I dont know what the Beosound is looking for but my QNAP isnt giving it. Twonky dont supoort NAS installs so back to QNAP I guess.

Are you running the latest firmwares/updates on the QNAP?

I was but then QNAP suggested rolling it back to a previous Firmware. I did this but it still didnt help. A technician engaged by Bang & Olufsen then tried a very old firmware version and it killed the QNAP. I then put the original firmware back on to it and have run the upgrade since. It still cant be found by the beosound. Unbelievable really. I keep thinking Im  missing sommething simple but the B&O guy was very tech and said he couldnt work it out. Just got the loan unit from B&O tonight but no joy. 

What about the ethernet cable from BS5 -> Switch? Could it be that by any chance?

It's pointing towards the QNAP, but I would try another cable too if possible.

I am running Twonky on a Windows machine and it works great!

I plugged in a loan Beosound on a different Ethernet cable with a different power supply tonight (it just arrived from B&O) and it also doesnt work. I have Twonky running on my laptop as a trial and it works fine with the Beosound. It is the QNAP I am now sure of it but nobody seems to know why. It is so, so frustrating. I have had a Beosound for 2 months and havent streamed a song from my NAS. Im so hacked off. Christmas and Chinese New Year havent helped with getting support of course. B&O have been very helpful that said. More than QNAP!

Thanks by the way Ari! Your ideas and support are appreciated. Think I need a linux guru!
