This, I think:







I am *not* the expert, but note:


"declarative metadata that is interpreted by the snap system to set up an
appropriately shaped secure sandbox or container for that application."


Does the equivalent set-up using non-snap software work?

dunno.
i don't even know what "snap" is (here it says: "snap - location of
genes from DNA sequence with hidden markov model"; but that's most
likely not what you want).

does the HDMI-output work with other software?

which samplerate are you running?
try running 48kHz.

Re: [PD] audio via HDMI output terminates Pd

[Simon Iten]

what are your settings? buffer etc.? try increasing the buffer and see if that 
helps. does PD actually output any sound in those first 10-15 seconds?
