Hi,
now I finally got grc running and I am trying to get familiar with it again.
I ran into some funny stuff.
First, audio sinks don't work. Device or ressource busy. THAT is kinda weird.
Of course, I have some stuff accessing the audio device but shared access
isn't an issue - normally.
enterprise:~ # fuser -v /dev/snd/pcm*
USER PID ACCESS COMMAND
/dev/snd/pcmC0D0p: sgofferj 4486 F...m knotify4
sgofferj 4568 F...m amarok
root 8976 F...m sd_espeak
sgofferj 12180 F...m sd_espeak
Audio out works neither as sgofferj nor as root. Audio in, however, works
fine.
Second issue:
I started with doing very simple stuff to freshen up my understanding of
sources, sinks, etc.
One of the first things I did was taking an audio source (mic) and straightly
feeding it into an FFT, Waterfall and Scope sink. FFT and Waterfall segfault.
Scope works.
Anybody any thoughts on that?
If some developers are reading here, advise me how to create backtraces and I
will be happy to assist with debugging!
