Hey there,
I have done some thorough google searches and I haven't found much on the issue, but in Linux the USB audio support for the Mdac is broken, and has been broken since around 2013/2014. I have seen mention of this mainly from people using a NAS system since they almost always run on a Linux varient, but obviously not many Audiophile type people run Linux otherwise there would be more threads over the net.
Here is a github page dedicated to a fix for the issue:
https://github.com/comps/ehci-mdac
"The Audiolab MDAC (an audio device) has some problems with recent Linux kernel versions due to split transaction scheduling in the ehci-hcd driver.
I'm going to investigate it further and push for a proper fix,
but in the meantime, there's this workaround."
This fix is now too old and not compatible with modern kernel versions, so Mdac is still broken. I have tried with various different distribtuions based on Debian and Arch, all are the same as it seems to be completely due to the kernel.
Now my point in posting this is: I know the developers of this device hang out on this forum occasionally. There are many DACs that work perfectly with linux. There are two ways for this to get fixed, one is for the Linux kernel to get patched for this specific DAC, or two; the developers of the DAC patch the firmware - which in all likelyhood is a smarter approach. It has been many years since an MDAC firmware update, what are the chances of this issue getting some attention?
For those who don't know, the issue is: when playing music there is a an audible 'ticking' sound like a metronome in the sound, usually every second.
Hope someone can help, I hope the developers can see this.
