No available API on x86_64 linux

[capsjac]

bindings-portaudio/example$ example-portaudio 500 500
Initialization: 0
Available APIs:
Opening the default stream: -9985
example-portaudio: user error (Failed.)

The system has ALSA installed and flashplayer works well.
Any workaround?

The first argument of example-portaudio is a sample rate (normally, it will be 44100 or 48000) and the second is a buffer size request (preferred range is 128~2048).

There are no audio devices that run with 500Hz sampling rate.

$ example-portaudio 48000 2048
Initialization: 0
Available APIs:
Opening the default stream: -9985
example-portaudio: user error (Failed.)

$ example-portaudio 44100 128
Initialization: 0
Available APIs:
Opening the default stream: -9985
example-portaudio: user error (Failed.)

$ example-portaudio 44100 2048
Initialization: 0
Available APIs:
Opening the default stream: -9985
example-portaudio: user error (Failed.)

It still doesn't work.
rate and buf are not used to list available APIs (as I see), thus there exists some issue other than mismatched arguments, I think.

Did you install bindings-portauio with -fALSA?

However, this issue will not occur as soon as I remove all the builtin things for Linux/Mac.

Is it okey?
(by the way, did you checked my email?)
