Change port names in 50-jack.conf from "alsa_pcm" to "system". JACK1 v0.125.0 still provides alsa_pcm:playback_* and alsa_pcm:capture_* port names, but only as aliases: $ jack_lsp -A system:capture_1 alsa_pcm:capture_1 system:capture_2 alsa_pcm:capture_2 system:playback_1 alsa_pcm:playback_1 system:playback_2 alsa_pcm:playback_2 JACK2 v1.9.12 doesn't support alsa_pcm:playback_* and alsa_pcm:capture_* aliases anymore, so 50-jack.conf will fail for JACK2 users: $ jack_lsp -A system:capture_1 alsa_pcm:hw:0:out1 system:capture_2 alsa_pcm:hw:0:out2 system:playback_1 alsa_pcm:hw:0:in1 system:playback_2 alsa_pcm:hw:0:in2 As you see in both cases system:playback_* and system:capture_* are correct port names.
