Hi all,

I'm using a Pi to auto run a script that runs pd-extended in nogui made on startup. On start up, the script appears to run fine, no errors in the log, but there's no sound. If I stop that process and then run the same script again manually, it runs fine and there is sound. I've tried putting a 1 sec delay between loadbang and dsp in the patch as suggested elsewhere, and I've also tried running the login script from both crontab and /etc/rc.local, both with the same results. Any suggestions?

@youcloudsofdoom I've found a larger delay than 1 second may be required (at least that worked for me). Might experiment with that number.

I solved it actually - turns out it was due to user permissions for the script in rc.local which meant the script didn't have access to the sound hardware. For future ref if you have this problem, you need to add the main user (in this case pi) to the rc.local script along with whatever you want it to execute.
