Hi Chris, I’ve learned a bit more since my last message - the story so far - when I first received the interface I installed ffado and tried to access the interface through jack, but jackd couldn’t start due to an error - I then noticed by accident I could access the interface through alsa without needing jack (or ffado as it turns out), and although it seemed to be quite an act to get it to connect it at least worked fine once a stream was established. I could also open ffado-mixer and change settings volumes etc. A day later I did a system update, and I believe my alsa got updated - at that point ffado-mixer stopped working due to a version mismatch (it reports its version is 2.3.0, but ffado is 2.4.2 - I’m guessing the ffado 2.4.2 is the alsa baked-in one). I think ffado-mixer is absolutely critical to the whole thing - without it many of the settings on firewire interfaces just aren’t accessible. I therefore think it quite negligent of the alsa maintainers to not include the mixer alongside the firewire stack code because as this example has shown updates to alsa have created a mismatch with the available ffado-mixer version from PPA. At this point I think my best approach is to find a 2.4.x version of ffado so the mixer is at the same 2.4.x codebase as the baked in alsa version, but only 2.3.x exists in a PPA so it looks like I’ll need to compile one from source. As for system instability I’m no closer to resolving that, but the on/off switch on the front panel of the Saffire is a complete no-no - I do not touch that while the PC is running, even if connecting to the device is proving troublesome… Of note is that the interface only seems to stay connected when applications talk to it, as soon as I close Ardour the stream disconnects - I wonder if getting the OS to establish a connection might help? Or would that block applications from using it? - who knows!
That’s where I’m at right now - I’ll keep plugging away at it, but frankly the “Full Support” status of the Saffire Pro 26 I/O on the ffado website is likely based on everything as it was probably when Ubuntu 12.04 was current 8 years ago, when jackd was a must have condition for getting one of these beasts running - now that alsa has incorporated the ffado code into a firewire stack, but left behind some critical pieces of the puzzle (i.e. the only mixer capable of seeing the freaking full range of controls!), then I think firewire audio in some ways has regressed.
