Hi Damien,
Thanks for the test report.
I have now successfully recorded with both the Mbox 2 and Mbox 2 Mini, however I had one occurrence where the Mbox 2 would not initialize even when I repeatedly unplugged and plugged it back. I have added your "magic" boot sequence back and since then I haven't seen this problem. I have been using that version ever since, so I cannot tell if simply unloading and reloading the driver would have fixed it. In any case I will re-submit the patch with the magic boot sequence for inclusion.
Cheers, Vik

Hi all,
I have tested Viktor's patch on "Mbox 2" and it works very well. Looks like my 'magic' boot sequence was not needed. Rate switching works between 44.1 and 48k. Good job.

Hi there,
I have recently bought a Digidesign Mbox 2 Mini and found the lack of support for 44100Hz sample rate in the driver limiting (the sample rate
was
hard-set to 48000Hz by the original author even though the device
supports
it, because he couldn't get the frame rate switching to work reliably).
I had a go at hacking the driver and came up with the following patch
which
appears to work on the MBox 2 Mini: https://pastebin.com/kzzTDj9T
I have built and tested this with Linux 4.8.15 without any realtime patches. I am planning to pick up a "full size" Mbox 2 as well, in the meantime if anyone on the list owns one I would appreciate if you could test this and let me know the result. There is a possibility that it
will
not work without the "magic" init sequence that I have removed because
it
does not look like it's needed on the Mini. Although I would be a bit surprised because the two devices are apparently identical to the point that the Mini allows the use of it's physically nonexistent features.
Once someone could confirm that this works, I would like to get it
merged.
This is my first attempt at submitting a patch for any Linux device
driver
so please let me know if I need to do anything else :)
At least it'd be better to the original author in the loop. Damien, could you take a look if you still have the device?
thanks,
Takashi
