--- Comment #21 from Fabian Maurer dark.shadow4@web.de --- As of https://source.winehq.org/git/wine.git/?a=commitdiff;h=20e5920135476cc4e3808... the patch is upstreamed.
I found something in the alsa docs:
https://www.alsa-project.org/alsa-doc/alsa-lib/group___seq_event.html writes:
Occasionally, this function may return -ENOSPC error. This means that the input FIFO of sequencer overran, and some events are lost. Once this error is returned, the input FIFO is cleared automatically.
And guess what value snd_seq_event_input returns when ev is NULL? It returns -28 (ENOSPC). Makes we wonder, should we better check the return value instead of ev? Also, do we want to log a warning of some sort?
Apart from that, I don't see a bug here we should report or investigate further.
