Crashes on Raspi 3 using pulseaudio

[Bebowi]

I'm using Raspbian Jessie Release 8.0

When i'm trying to start librespot on my Raspberry Pi 3 using PulseAudio backend

RUST_BACKTRACE=1 ~/librespot/target/release/librespot --username my@email --cache /tmp/librespot --name Libre -p MySuperStrongPassword -b 320 --backend pulseaudio

it crashes with following message:

It works fine on my ubuntu VM, so I thought it is caused by the version of Pulseaudio. After an Update to Pulseaudio 10.0 the same issue occours.

I want to use Pulseaudio for several reasons:

1. With Portaudio write underflow occours from time to time
2. I want to do some further work in network

Any Ideas what is wrong on my Raspberry?

Hi, I've had the same issue for a while on my RPi3, Jessie 8.0 as well. Got a crash on connection from the Spotify client and it seemed to be related to pulseaudio. I deleted my cloned repo folder and re-cloned it with git clone https://github.com/plietar/librespot.git and then rebuilt. That got it running for the first time in a while. However, I still see the same errors involving pulseaudio, so I'm not claiming victory just yet (as it also seems nothing like a permanent solution). So, This is what I got:

I'll update if it crashes again. Good Luck!

@TurokO8A You don't use pulesaudio as backend. What you are discribing is a normal start using stadard backend (Portaudio).

Any ideas regarding my error?

You have to run PulseAudio and librespot with the same user.
