alsa-project/alsa-lib issue #440 was opened from reuk: https://github.com/alsa-project/alsa-lib/blob/df8f1cc1ec9d9ee15be5e2c23ad25b9389fd8766/src/seq/seqmid.c#L585-L589 I think this call in seqmid.c is incorrect. According to the docs, the second argument to `snd_seq_port_info_set_ump_group` should be a 1-based group number (probably 0 for the UMP endpoint). I'm testing on Fedora 41 with alsa-lib-devel 1.2.13-3.fc41, and I'm seeing the following printed to the console when I call `snd_seq_create_ump_endpoint`: ``` ALSA lib seqmid.c:592:(snd_seq_create_ump_endpoint) Failed to create MIDI 2.0 port ``` Issue URL : https://github.com/alsa-project/alsa-lib/issues/440 Repository URL: https://github.com/alsa-project/alsa-lib
