If there are no available audio outputs in the list from `shairport-sync -h`, it's a sign that the program has not been configured properly before being compiled. You need to ensure that you include the output backend(s) you want.\r\n\r\nThis is the standard, recommended in the [README.md](https://github.com/mikebrady/shairport-sync/blob/master/README.md) guide:\r\n\r\n```\r\n./configure --with-alsa --with-avahi --with-ssl=openssl --with-metadata --with-soxr --with-systemd\r\n```\r\n\r\nNotice the `–with-alsa` – that includes the `alsa` back end. This is what you get in the relevant part of the `shairport-sync -h` output:\r\n```\r\nAvailable audio outputs:\r\n    alsa (default)\r\n```\r\nI hope this helps."}}
