AudioFuse Studio

[freysteinn]

Hi all.

I have an AudioFuse Studio, and I wanted to hear if you have had issues getting the sound working in Linux. When I plug mine in, I get a robotic-sounding sound, and I have not gotten my microphone working. Is this something you have encountered?

Best wishes

To clarify, I have tried it both on Fedora 32 and Ubuntu 20.04 LTS.

I only have the regular, first-generation AudioFuse and I haven't had issues like that. You might have better luck asking somewhere like the Linux Musician's forums.

My only suggestion would be to try changing the sample rate in something like Jack. Occasionally it sounds like my computer and audiofuse disagree on what the sample rate should be and that leads to my audio being a distorted until I fix it. Usually I think the disagreement is minor (probably 44.1khz vs 48khz) so I can understand the audio, it's just pitched wrong and has some stuttering. I'm not sure if what you're describing is a more extreme version of that.

@freysteinn Did you ever resolve this issue? I'm considering replacing my RME Babyface Pro with the AudioFuse Studio for a bit more I/O and easier control on the hardware. I found another report that seems similar to your experience but I can't find anything else about the AudioFuse Studio with Linux online. Have you tried with recent Linux kernels? There have been some changes to the snd-usb-audio driver lately which perhaps could have impacted the bug you ran into. It's also plausible the bug was in a higher level of the audio stack. Were you using PulseAudio, JACK, PipeWire, all of the above?

Hi @Be-ing.

Unfortunately, I ended up giving up on the issue. The Arturia staff was helpful and did consider providing official Linux support because they currently support Linux on some of their AudioFuse products, but not the Studio. However, they decided not to provide Linux support for the AudioFuse Studio in the end, and they helped me return my device. So, while I did want to be helpful and even would have been willing to help with code, it was easier to give up my AudioFuse Studio for my old setup.

A programmer named Jonathan Laventhol contacted me about his interest in working with Arturia to provide support for the Studio. I did not follow up on how that went. Maybe if he reads this, he can shed some light on the status of that work?

Thanks for the quick response. I am glad to hear that Arturia didn't just write you off and had the decency to let you return it.

I have been working on reverse engineering my RME Babyface Pro's mixing controls to write a Linux replacement for RME's TotalMix FX application. I've figured out most of the USB signals so far apart from the onboard EQ. Considering my progress with this, I'll more likely end up getting one of the larger RME Fireface interfaces instead of the AudioFuse Studio. The AudioFuse Studio seems like a really nice device, but I realized it wouldn't make much sense for me personally to get an interface between the size of the Babyface Pro and a larger rack mountable unit. I use my Babyface Pro with my Pinephone and portable speakers, which all fits in a normal sized backup. Conveniently for this, the Babyface Pro comes in a hard plastic case, but the AudioFuse Studio doesn't have a case.
