Probing the output:analog-stereo-output+input:analog-stereo-input profile fails during startup. I don't know why it has stopped working. Are you able to do capture and playback simultaneously with plain alsa tools? Try running these two commands in parallel: arecord -Dplughw:2 -f cd > /dev/null aplay -Dplughw:2 /usr/share/sounds/alsa/Front_Center.wav If aplay fails while arecord is running but succeeds when arecord is not running, this is not a PulseAudio issue. -- Tanu _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
