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?

@ComlOnline This looks to me like the user has not been added to the pulse-access group. So
adduser <user> pulse-access should fix this. You only get this error message with the old plietar version.

But still I've not been successful running the libresport-org version on a similar setup using a Raspberry 3 with Raspbian Stretch Lite and Pulseaudio 10.

./librespot -n Librespot --backend pulseaudio

gives me an error on playback:

@raphaki Either way it's been so long I'm going to close this issue anyway. If you built Librespot using cargo build --release it will only include the PortAudio backend. Try rebuilding using this cargo build --release --no-default-features --features pulseaudio-backend. If you still get a problem please open a new issue.
