Check this https://github.com/shichao-an/soundmeter/issues/7

All you have to do is install ALSA : sudo apt-get install libasound-dev

then build portaudio (this version pa_stable_v190600_20161030.tgz) http://www.portaudio.com/download.html

then Get root privileges (sudo su root under Ubuntu where plain su root does not work.)

Place the portaudio archive in /usr/src and unpack it with tar xvfz pa_snapshot.tgz This will generate the directory /usr/src/portaudio.

Descend into this directory and execute these commands:

./configure

make

make install

ldconfig

The linrad configure script has to be run after the successful installation of portaudio to make Linrad aware of the fact that portaudio is available.

Make sure you get ALSA as yes in the ./configure file
