Just installed OpenWRT trunk on my HG553, then I Installed all the kmods for usb support and audio support and finally I installed shairport-sync but something gone wrong...

Also shairport-sync won't start at boot, even with /etc/init.d/shairport-sync enable /etc/init.d/shairport-sync start

Sorry for my bad english

Hi there. Thanks for the post. I'm afraid I don't really know what is missing from your setup. I suggest installing alsamixer or aplay to see if you can use the audio system separately from Shairport Sync. In this way, you can determine if the problem lies with Shairport Sync or with your system.

Just for information, what version of Shairport Sync is running. (Enter shairport-sync -V and note the result.

Hi, probably there was a problem with the kernel in that version of OpenWRT. Backing up to Chaos Calmer everything works fine. Sorry for the issue.
