The problem started at the same time kernel 3.19.3 came out for

something in userspace.
Hi Jörn,
there definitively also is an issue with this kernel.
[rocketmouse@archlinux ~]$ uname -rm
3.19.3-3-ARCH x86_64
[rocketmouse@archlinux ~]$ aconnect -i
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 14: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
[rocketmouse@archlinux ~]$ amidi -l
Dir Device Name
IO hw:0,0 HDSPMx579bcc MIDI 1
IO hw:1,0 TerraTec EWX24/96 MIDI
IO hw:2,0 TerraTec EWX24/96 MIDI
I only use linux-rt, but an user of this kernel noticed it and started a
thread here:
https://lists.archlinux.org/pipermail/arch-general/2015-April/038789.html
Curious coincidence: a few weeks before LAC2015, I tried to connect a
BCF2000 to the LAC streaming box, and even though lsusb showed the
device, ALSA did not catch it, ever. This box ran Manjaro, which, IIUC,
is a derivative of Arch.
I'm not sure any of this is actually related to the JACK issue, but yes,
something is fishy about 3.19 :)
