[ERROR] "Address already in use"

[Ema82]

Hello,
I'm trying to install Spotifyd on a Raspberry Pi 3 Model B with RuneAudio (http://www.runeaudio.com/).
I followed all the instructions of the related Wiki page but if I check Spotifyd status after starting it, this is what I get:

[root@runeaudio ~]# /usr/bin/spotifyd --no-daemon
22:41:13 [INFO] Using software volume controller.
22:41:13 [ERROR] Caught panic with message: called `Result::unwrap()` on an `Err` value: Os { code: 98, kind: AddrInUse, message: "Address already in use" }

Could anyone help me figure out what the problem might be?

Thanks in advance
Ema

Solved killing all the active processess. After restarting the Raspberry, spotifyd works correctly.

I had to reinstall Runeaudio and Spotifyd and I'm having the problem again.
This time using killall -u root to kill all the active processess doesn't solve the problem.
Any help?

Thanks

There is a process listening on that specific port. You can investigate with ss -tulpn. Maybe there is still the executable running from RAM. Is the problem still there after a reboot?

Thanks for your answer elju.
Reboot doesn't solve the problem.

This is what I have with ss -tulpn:

I have no idea of which is the service that occupies the door that spotifyd trying to reach nor what I can do if there is actually an overlap

[mainrs]

It is probably the 5355 one as the port range for the discovery service is is somewhere between 5000-5400 most of the time. It can get higher though.

You can try to run netstat -ltnp | grep -w ':5355' to check what program listens on that port. Additionally, lsof -I :5355 tells you what service listens to the port.

netstat is part of net-tools on ubuntu/deb. lsof is a package by itself. They are available for almost any Linux distro in some way or another.

[mainrs]

I am closing the issue for now. Feel free to re-open it if you need more help.

[xaltsc]

I can't reopen this issue, however, I'm having the same problem, I tried to investigate ports with netstat, but the only program listening is sshd on another port.

I'm launching spotifyd with ./spotifyd --no-daemon --verbose -b pulseaudio -p pwd -u login -d device.
