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?

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
