Shairport enabled ubuntu 20.04 pc missing not showing up on ios 14.6 and 14.7 #1248

Closed s3vhub closed 3 years ago

s3vhub commented 3 years ago

Hi,

On my pc on 17th July i had installed Linux mint 20.04.In that once installed my pc was visible to my iphone as airplay device but as audio wasnt there even after trying all the troubleshooting steps i had to install pulse audio.It worked but i wanted to find out issue with alsa.So uninstalled pulse and reinstalled alsa.The whole cinnamon desktop crashed and so i now installed ubuntu 20.04LTS. ISSUE:- On 20.04 LTS since 19th july i am unable to find my PC as an airplay device as opposed to the linux mint version in which case it showed up seamlessly. I have tried many ways but it isnt working.Did all thats mentioned in read.me file.Didnt work. With everything else on the network constant other than the OS i fail to understand why the pc doesnt show up as airplay device on my iphone which was on 14.6 on 19th july and currently since today on 14.7.

Please find the o/p of

sudo systemctl status shairport-sync

Thanks for the reply Mike.I had done everything on the troubleshooting page with not much luck.However the thread in the reporting issues..i will follow that once again.It may not be of much help in my case but let me try again and will revert with my findings.

I believe its something to do with ubuntu 20.04,shairport and the network as if it had been just the ntw then it wouldnt have worked with linux mint on my machine just two days ago.I just am unable to find the root cause for it.

done everything i could with no luck.I even did reinstall ubuntu 20.04 multiple times and checked to reverse any changes.

On the current install i get this

seeing the port stuff in the second last line i did edit config file and set port to 5006 after this same error was thrown for port 5005.However same issue. Any idea?or i would have to ditch ubuntu and move back to linux mint

Thanks. The log above indicates that Shairport Sync was already running as a daemon in the background when you tried to run another copy of it from the command line. Those ports are already in use because the daemon version of Shairport Sync has already started. In fact, it looks like the daemon version is running fine. It should appear as Homepc.

It is extremely unlikely that Ubuntu 20.04 is the cause of any problems -- it's been used to develop Shairport Sync.

Is the IP number it gets in the same subnet as the iPhone? (If it's a VM it might be in a different subnet.) Does it have a firewall running? Does the router have a firewall running? Have you tried using Discovery on the iPhone and avahi-browse on Ubuntu to see if mDNS is working?

This will sound damn crazy.moved back to mint again.same issue.Now my home braodband wifi missing there too. So just out of curiosity switched on mobile hotspot and connected by PC to it and bam..the pc was discoverable. So moved back both again to my home wifi.No luck.Again PC dissapears unlike yesterday. all this time the "discovery app" is running on my phn. Issue:- 1.Iphone and PC on my home wifi.discovery app keeps searching.nothing there. 2.Now move both to my mobile hotspot.The pc appears as airplay device.Discovery app shows the entries as expected.

firewalls been disabled all the time.i have henceforth added the exceptions.

I restarted my fiber modem+router.Still no luck when on home wifi.

You are right.Its neither ubuntu nor mint.what i cant figure out is this as to why yesterday it worked seamlessly on my home wifi but today not at all.havent changed anythng on router etc.Why its working on mobile hotspot but not on wifi.

i did avahi-browse -a. now it shows on hotspot

however on the wifi

Edit:- fixed on linux mint.It was the mac address binding hidden under the menu which was hard to find.refreshed and cleared out.That seems to have fixed it.Next let me go back and try this on ubuntu

s3vhub commented 3 years ago

Hi Mike, Sorry for the trouble.was able to spot the issue.Actually its the mobile hotspot that let me narrow it down. Removed the binding of the previous pc name before the uninstall of linux mint.Clearing and refreshing that on the ONU router fixed the issue.Installed ubuntu 20.04 LTS now and it works seamlessly now.

Yikes, it's great that you found the problem. Happy listening.
