Different ALSA input and output devices


In the Audio/Midi Setup dialog, with Audio System set to ALSA, there are separate input and output drop-lists, suggesting that you can capture input from one device and send output to another. However, whatever combination I choose I get an error box: “Audio device not valid”. Are there any situations where this is actually possible?

I’m using Ardour 5 on Ubuntu Studio 16.10. My primary audio device is an RME Babyface (UAC2 class compliant) and I have a couple of other USB audio devices that I would like to capture from whilst playback is still sent to the Babyface. (I’m monitoring externally.)



That “suggestion” has been fixed in 5.5. The only valid option for separate devices is to allow setting one set to “None”.

Ardour won’t resample to allow sync’ing different devices with different clocks. the only way to use this is currently is http://jackaudio.org/faq/multiple_devices.html

Thanks for the confirmation. I just wanted to make sure I wasn’t missing something.
