alsa-project/alsa-utils issue #232 was edited from symdeb: How to reproduce: 1. Plain Ubuntu 23.04 desktop but with kernel 6.5rc7 and ALSA UMP & sequencer enabled. 2. Insert a MIDI 2.0 UMP capable device Note: A Focusrite 18i20 Gen 1 audio interface is used for audio playback and set in Pavucontrol as "pro Audio" 4. play a video with the "video" application. 5. run aplaymidi -l or palaymidi --version 6. Error appears. Unplug the device Wait for about 30 seconds (this is important, sooner the error will appear) Repeat steps 3 and 4 . The error won't occur.  This is not unique to aplaymidi, other ALSA clients may also cause this error. in other applications such a web browsers , as playing videos in Youtube,, the audio playback just stops.
