I have a Roland Quad Capture audio2usb adapter, which I believe is quite a popular and high-quality interface. I desperately want to get my whole DAW running on Linux and am therefore looking at Bitwig.

It seems that the QuadCapture is not supported under Linux. Since the Linux version of Bitwig is such a big advantage, does Bitwig interact with companies like Roland in order to create Linux support for their products?

Did you ask Roland, already?

This fb post states it to be working (not by support of the manufacturer though, only by the community):

by the way if it´s not supported by ALSA, it doesn´t mean JACK can´t use it. :)

i would recommend JACK AUdio Connection Kit on linux.

actually that is incorrect. If it isn't supported by ALSA or OSS then Jack won't support it. Jack does not specifically have drivers for any sound cards, it is a communication layer but does not have any drivers.

or ffado, but as that isn't a firewire device it wasn't relevant.. (which can only be accessed through JACK, but is still the driver layer) ..

You are right, but i just wanted to mention that my Focusrite 18i20 is not listed by Alsa by default, so i can't use it without jack at all... Or maybe im doing sth. wrong... So i just wanted to give that hint.

It's probably not setup as the default device, but you should still be able to use it in ALSA... If go to a command prompt and type aplay -l, you should see a list of the available ALSA devices. e.g.

allan@allan-PORTEGE-R930 ~ $ aplay -l * List of PLAYBACK Hardware Devices * card 0: PCH [HDA Intel PCH], device 0: ALC269VC Analog [ALC269VC Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 .........

That being said.. using Jack is the better option. UNfortunately Bitwig doesn't support JACK MIDI yet which enforces sample accurate sync with audio

Okay well, i guess i still have to learn a lot... how do i set my default Alsa playback ? Guess i have to change a script file ?


answered Jul 08 '15 at 08:53 by Beerhunter (6)

Okay. So the best way to do that is create a file under your user home.. named .asoundrc.

include the following

pcm.!default { type hw card 0 }

ctl.!default { type hw
card 0 }

However substitute the 0 in card 0, for whatever your focusrite comes up as in aplay -l That should do it.

Have a look here

and here for more complex tips.

I've been using firewire for years.. but this is basically it.. (recently proud owner of an A&H Zed r16 before that had a focusrite saffire pro 10io)

works, but only with Audcity... any solutions how to make it work with VLC or Youtube vids ?


answered Jul 08 '15 at 18:06 by Beerhunter (6)

All I can think of is putting that same script in /etc/asound.conf You can try the ALSA-user or lau mailing lists for more help.
