Merging AES67 ALSA driver

[bluebell]

Try to find out how ALSA sees the card:

Code: Select all

aplay -l
arecord -l

Is it possible that you have to set the sample rate on the interface, too? Is there a menu to do this?

From the look of it, everything seems fine when listing devices :

The interface is set to 48KHz from the onboard menu.

I usually use cadence to start Jack and I was wondering if maybe it had something to do with the number of inputs and outputs in Cadence's configuration. On the interface I can turn different IOs on and off. Could it be that the interface is showing a certain number of channel and I just didn't enter the right amount ? (I've already played with this without any results so far).

Update :

I've sent the mt48 back. It's a bit disappointing but it is what it is.
I'll keep whit my x32 for now and maybe get the Wing Rack when it's released since it could serve as a USB Dante bridge.

I just bought an mt48 and connected it to my audio workstation (ubuntu studio 20). Although the device is recognised as USB ethernet and as an audio interface, when I go into alsamixer it tells me there are no controls for it. Jack shows a similar message about lack of controllers. I googled mt48 linux and this was the first of a handful of links. Since has been about a year since the last post here, I was wondering whether any progress had been made ? Would it be helpful to upgrade ubuntu studio ?

Not a fan of Windows at all but it seems like an uphill struggle to do pro level audio production on Linux/ I was doing all right for a while running Reaper and Komplete, but it seems like Linux is still viewed as a "Fringe" OS, even after decades of development, and as we all know it is srill the best choice when it comes to stability and streamlining. So I am keen to get this working; otherwise I might be forced over to the "dark side".
