Sometimes the sound works for me on OpenCPN, sometimes not. I have tried to pinpoint what is going on.
When first booting up and starting Ocpn, the sound always works.
Later after using some flash based website radioplayer, there is no sound in ocpn."top", reveals that, a pulseaudio process is still an active left-over from the web-radio, even though the player is killed and that page is not loaded. This process obviously blocks opencpn audio.
takes care of this, and opencpn audio(alarms) once again works. Now, if I once again want to listen to web radio
I have to restart firefox.
shows that pulseaudio is still running, but obviously the web-radio application is unable to reset itself and connect
I have not yet come up with exactly what's going on.....
Testing gives the same result for my old box(gnome, kde, xfce) 10.04 and Eeepc 901,Ubuntu NBR 10.4.
