After reading this article from Instructables I wanted to try it out in Ubuntu. Luckily QSSTV is available but I'm having problems getting it to work properly.
When pressing the green light (to receive data) I get this error:
After going to Options > Configure > Interfaces I discovered that it's attempting to use /dev/dsp which doesn't appear to exist.
In my /dev folder there are no files that reference sound devices and I've tried all of the devices in /dev/snd but unfortunately none of them work.
Is there a specific audio device that I should be linking to?
In January 2012 QSSTV received an update (including an updated interface) that fixed the sound problem. It can be downloaded from here
