Description of problem:
I'm using pulseaudio as a sound processor and filter in my hifi setup.
Pulseaudio has ability to dynamically re-sample its feeds and therefore
can be used to for feeding input from one sound card as output to another
sound card. Configuration which triggers the crash takes 4-channel analog
input from usb audio-interface and feeds it to hdmi input of the receiver
which does not have multi-channel analog inputs.
This crash was triggered by following config:
pacmd set-card-profile alsa_card.pci-0000_00_0e.0 output:hdmi-surround
pacmd load-module module-remap-sink sink_name=quad_sink master=alsa_output.pci-0000_00_0e.0.hdmi-surround channels=4 master_channel_map=front-left,front-right,rear-left,rear-right channel_map=front-left,front-right,rear-left,rear-right remix=no
pacmd load-module module-loopback source=alsa_input.usb-BEHRINGER_UMC404HD_192k-00.multichannel-input sink=quad_sink
It works for 10-20 seconds and then crashes.
Version-Release number of selected component:
cmdline: /usr/bin/pulseaudio --daemonize=no --exit-idle-time=-1 --disallow-exit
runlevel: N 3
