**Describe the bug**
I'm trying to pipe a portaudio source to an Icecast server. Running against a
local Icecast server, I'm able to get audio coming back from Icecast:
```
#!/usr/bin/env liquidsoap
set("log.file.path", "cast.log")
set("log.stdout", true)
# Audio source
source = mksafe(
input.portaudio()
)
output.icecast(
%mp3(bitrate=320),
host = "localhost",
port = 8000,
password = "hackme",
mount = "stream",
source)
```
However: if I change the server from my local machine to a remote machine,
liquidprompt exits with an error:
```

```
I've no idea how to debug this any further!
**To Reproduce**
Run my script against a local icecast instance, then against a remote icecast
instance.
**Expected behavior**
I expect the audio to send throught to the remote icecast server at the same
level of quality as the local one.
**Version details**
- OS: OSX
- Version 10.14.1
**Install method**
I installed via opam
