hang upon suspend/resume with USB microphone - JackAudio

9 Apr 2021

Hi,

I'm using a Blue Snowball that I activate with a script

#!/usr/bin/zsh
HARDWARE_ADDRESS=`arecord -l | grep "Blue Snowball" | sed -e "s|card
\([[:digit:]]\).*Blue Snowball.*device \([[:digit:]]\).*|\1,\2|"`
case $1 in
    "jack")
        alsa_in -d hw:$HARDWARE_ADDRESS -c 1 -p 512 >/dev/null &
        sleep 2
        jack_connect "alsa_in:capture_1" "PulseAudio JACK
Source:front-left"
        jack_connect "alsa_in:capture_1" "PulseAudio JACK
Source:front-right"
        ;;
    "monitor")
        jack_connect "alsa_in:capture_1" "system:playback_1"
        jack_connect "alsa_in:capture_1" "system:playback_2"
        ;;
    *)
        pkill -f "alsa_in -d hw:$HARDWARE_ADDRESS" || true
        ;;
esac

When I forget to have the script kill alsa_in and I suspend the computer
it hangs upon resume. This is using Manjaro/KDE. WHat would be the
recommended way to fix this?

Thanks in advance.
