Solved: Shairport-sync failure to play
#1
Solution: old iPods are not supported by shairportsync, recent ones, on the other hand, work perfectly
the issue I opened and closed on shairport-sync github

Hello, and congrats on the software, it truly is the best thing since sliced bread...

I have a bit of a problem with shairport-sync or airPlay as you might know it

I try to play music from a very old iPod Touch (circa 2009), it works well whith LibreElec (which uses shaiport), but whenever I try to play anything on moOde it segfaults.
So, as I am not a complete moron, I searched through the interwebs to see if my problem could be reproducible, and it appears it is not.
Then, i went through the config file, to see if I could change some options to see if I could make it work, it did not.
Eventually, I upped log output for shairport-sync and ended up with this (it's complete, from initialisation to segfault)

My moOde install is pretty straightforward, albeit I have done some tweaking to enable covers availability for my android mpd clients and also installed and configured lirc to recycle an old remote that was sleeping in the bottom of a drawer.

Hardware wise, my moOde player is comprised of a Raspberry Pi 2 and an Allo Boss Dac and the settings are pretty much default on moOde 6.7.1.

I believe my post is complete enough, but if you need some more information about my setup don't hesitate to ask, I'll gladly and diligently answer

Thanks in advance for the help you could give me

Also, bear with me as English is not my native language

Hi,

I would recommend posting in the shairport-sync repo. Be sure to include the log output and also mention its an older iPod touch https://github.com/mikebrady/shairport-sync/issues

The shairport-sync version used in moOde.

pi@rp3:~ $ shairport-sync -V
