Comment 5 for bug 1854676

Olivier, it's not the webaudio that does not work. It's the webmidi.
As in the 2 last examples on the demo list:

https://ryoyakawai.github.io/smfplayer/
http://webaudiodemos.appspot.com/MIDIDrums/index.html

In my testing the drum machine doesn't ask for permission to use midi. So that might be a bug on the websites part. But when smfplayer loads, this comes up in the teminal:

ALSA lib conf.c:3916:(snd_config_update_r) Cannot access file /usr/share/alsa/alsa.conf
ALSA lib seq.c:935:(snd_seq_open_noupdate) Unknown SEQ hw

Might be usefull :)
