I am using a new sound card in a linux machine running ubuntu 20.04. I’m pretty sure this card is working with ALSA since I can send/receive audio through Reaper.
When running the audioSettings demo in the demo runner I am presented with 11 different audio devices which are all from ALSA, these include devices such as “PulseAudio Sound Server”, “Open Sound System” and 3 devices that have the name of my sound card: “RME MADI_ae811b, RME MADI; Direct sample snooping device”, “RME MADI_ae811b, RME MADI; Direct hardware device without any conversions” and “RME MADI_ae811b; USB Stream Output.” I understand these are software devices.
In the demo runner whenever I try to select one of these I get either ‘Invalid Argument’ or ‘No Channels.’
I believed this was a problem with PulseAudio interfering with ALSA however disabling PulseAudio seemingly has no effect.
Does anyone know where the problem might lie for this?
