ARMv6 isn't directly supported by Fedora, either, so the
point is somewhat moot.
There is a D2Plug (2nd generation DreamPlug), which also has
audio, but with the CPU clocked at 2/3 of the old DreamPlug
it might actually be slower - but it is an ARMv7.

If you're going to look at respins the field opens up a bit,
I guess.

Indeed. Do you have a form factor preference, though?
Most solutions like this have some uglyness associated, e.g.
an external power brick. D2Plug is a single brick, just
plug into power socket. But performance could conceivably
be an issue.

ARM based multi-TB NAS is actually quite doable:

I have it running with 4x4TB HGST drives and ZFS (fuse) RAIDZ2.

Depending on the form factor you are looking for, there are
ARM boards out there with PCI/PCIe slots. You could get one
of those and use a PCI/PCIe sound card in it. It would be a
lot more expensive, though.
On the cheap, there are always USB audio options. A USB
sound dongle can be had for about £2, and you could plug
that into any ARM device featuring a USB port (i.e. most
of them these days).
