Plasma 5 + pulseaudio crashes



If you occasionally get other cards in phonon than your real devices, something is blocking pulse from starting. can you post

sudo fuser -v /dev/snd/*

when it doesn't work and crashes? shm errors are also kinda worrying. I don't know if the bug is still there, but are you using a java program and use openjdk7 as your java implementation? There is (was?) a bug that leaked shared memory and lead to all kinds of issues not unlike the one you are experiencing here. Switching to openjdk8 might be an option here.
