Input device not listed in qjackctl but available in Alsa

Forums

Hello,

I was wondering why my ALSA device was not listed in qjackctl

I can clearly see it in alsa, but it does not appear as I try to add it in the patch bay

arecord -l

**** List of CAPTURE Hardware Devices ****
card 1: US2x2 [US-2x2], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0

thanks

because you probably compiled qjackctl yourself without ALSA API support?

this is most probably the same reason why you get the ALSA tab grayed out on the other topic.

if your on debian/ubuntu based distro, please install libasound2-dev package and build and install again from a clean source;
if you're on fedora, install alsa-lib-devel; on opensuse it's alsa-devel.

in summary you have to make sure the ./configure step reports this line:

  ALSA MIDI Sequencer support  . . . . . . . . . . .: yes

hth.
cheers

- no actually as I mentioned, I have the same issue with the official raspbian jackctl package where the alsa button is not greyed out
- also, it's a sound card, so I am talking about audio ( for midi devices, I used a2jmidid)

is there a way to list jack recognized devices ?

qjackctl lists no audio output devices but sees only alsa midi devices (and a2j devices in the midi section)

anyone ?
btw I recompiled qjackctl with alsa support it does not change anything, my sound card is still not recognized
