If I type the following at the terminal I get the expected tone..
/usr/bin/padsp /usr/bin/tones sine 100 900
...but if I try this from within some C code on a R-Pi Zero...
system("/usr/bin/padsp /usr/bin/tones sine 100 900");
I get...
[tones] Connection refused : /dev/dsp
and with -d on...
utils/padsp.c: dsp_open()
utils/padsp.c: fd_info_new()
utils/padsp.c: pa_context_connect() failed: Connection refused
utils/padsp.c: freeing fd info (fd=4)
utils/padsp.c: Draining.
utils/padsp.c: dsp_open()

Can anyone please put me right ?
Thanks,
