Hallo, I try to run a morse code program from procmail to produce an audible signal when mail arrives. My postfix(MTA) calls procmail(mail delivery agent) to deliver the mail. This obviously runs in the background. :rpocmail calls morse to give the signal that mail has arrived. However morse produces an error: ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused I'm using CentOS-7 right now, earlier I used CentOS-6 and then it worked perfectly. I suspect it is a matter of permissions, but I can't figure out where it goes wrong. Do you experts have any ideas????
