Some devices comes with all the routing muted, and without the software from the brand, that work only with Win/Mac. You just have a 3000 $ piece of hardware silence. Happy to find the USB is detected in the Kernel log though. Like this one : https://www.prismsound.com/music_recording/products_subs/atlas/atlas_home.php They claiming «This is a UAC2 (USB Audio Class 2) interface supported natively in Mac, iPad, Linux and Android, and in Windows via a driver. » But you need their software to make initial routing/control. Or at least some «alsa mixer» to control it. Does not exist as far as i know. So, paying 100 % of the price to have 1% of the functionality....or 0% (perfect silence...) Focusrite with his series 2i2, 2i4 ( 1st or 2d generation) have another way to do it : routing is default to everywhere, and you can control what you want with switchs/buttons and knobs. Very effective, but limited cards (compared to some Prismsound or Antelope cards) not so expensive also. > I don't had the money to buy a RME class compliant USB device, but > since I've got a job now, I much likely will replace the Focusrite > with a RME USB device. RME as a very special way to do UAC2 - USB Audio Class 2. More an «RME-ish USB Audio class as i want to do it». Maybe it's enough for someone's need. But it's only from my little experience with RME's cards. Sound Devices have also this problem (USBPRE 2 card) never fully worked (the card think Linux is windows without ASIO and fallback to 44100 hz only) >From my (small) understanding & knowledges there is only 3 solutions : (with UAC2 standard respect we all know) Brands use hardware controls on the card (like Focusrite did with 2ix serie) Brands start to produce code in the Kernel/Alsa to have perfect interface/control of theirs cards. Brand start to embedded their control softwares in the card that you can use with a web browser - as MOTU cleverly did. We know that since begining of age with routers/modems/switchs why not in audio ? Let me quote Ardour's dev page about this : «You can thank the brain dead morons in the audio technology industry for this situation.» All the best. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
