Dear list,
I am trying to play video with synced audio on HDMI output, but after 10-15 seconds Pd dies with an error:
pd: pcm.c:1168: snd_pcm_prepare: Assertion `pcm' failed. Pd: signal 6 Can you help me to fix this issue?
Ubuntu 18.04 with ALSA
Best, Popesz
and an other error which slows down the PC significantly appears in terminal:
alsa xrun recovery apparently failed restart alsa output

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?

Yes, they are not installed. which one you prefer, or could be more stable?

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.

This, I think:
https://en.wikipedia.org/wiki/Snappy_(package_manager)
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?
Best

The audio worked from other software without problem. Installed pulseaudio and its gui from apt. In Pd portaudio is still blank, no device to choose. Do I still miss anything?

Still fighting. Installed jackd, connected pulseaudio to Jack, but still nothing. This is how it looks like: [image: Screenshot from 2019-12-15 21-21-33.png] Do I have to install PD from scratch if Jack was not present during the last installation?

i dont know how you obtained Pd. if using the system packages (via apt), they'll have jack support built in. if you compiled Pd yourself, you would have needed to add "--enable-jack" to the configure flags (and have the jack-dev package installed)
finally, you must of course select Jack AS the audio backend...

Did not manage to fully repair the audio problem on HDMI. Reinstalled pd with apt-get, and started with *pd -alsa -alsaadd pulse -audiooutdev 5 -noadc* where 5 is the HDMI output. Now the 2 minutes video play until the end and quits with error as below:
pd: pcm.c:1167: snd_pcm_prepare: Assertion `pcm' failed. Pd: signal 6 pd-extern: EOF on input
and
pdsend errorname: >>error writing "sock55d791aa9930": connection reset by peer<<
Does it mean anything which takes me closer to solve this issue?

Ah okay, then it will probably not help you, but what I did in my raspberry pi to use audio via hdmi is:
- sudo raspi-config and there say "force audio through hdmi"
- then just use alsa in pd and it works (without startup flags)
