Using PortAudio gives errors in precompilation while works in REPL #103

In the REPL, using PortAudio and creating a stream work just fine and also the available devices seem to have been recognized without problems:

julia> using PortAudio

julia> PortAudioStream(1, 0; eltype=Int16, samplerate=44100.0, latency=0.001)
PortAudioStream{Int16}
  Samplerate: 44100.0Hz
  1 channel source: "default"

However, when I add using PortAudio (and nothing else!) to a package, then it this package gives many errors in precompilation:

Thus, I wonder: should PortAudio.jl move some of these initializations from precompilation time to module load time (__init__())?

Hi, thanks for the report. Those aren't errors per say, just ALSA messages about alsa trying to figure out your sound setup. We redirect them to the debug log during __init__. Ref https://github.com/JuliaAudio/PortAudio.jl/blob/f6cd300ec8716853fd41043da2232d42c680baee/src/PortAudio.jl#L111 . It seems that's not working in some circumstances, but I'm not sure why.

@bramtayl, thanks a lot for your reply. I see - I also found the related issues on PortAudio... Might it be that https://github.com/JuliaAudio/PortAudio.jl/blob/f6cd300ec8716853fd41043da2232d42c680baee/src/PortAudio.jl#L20 does already initialize some ALSA stuff and cause these error messages?

Hmm, no I don't think so. I'm guessing the issue is Pkg and error capturing don't work well together.
