Progress on Boss 2 driver issue

[kenship]

Hi,

I've been using 8.3.0 and with 8.3.7 released I want to try it.

I installed it on a new SD and of course I have no sound from BOSS 2. I tried

$ sudo rpi-update pulls/5510

Ran it a few times, based on what I saw I have problem downloading and couldn't extract the file. The last statement was:
Invalid artifact specified. Response: 404

I wonder if any one knows whether I have done wrong or there's another solution that I can try.

Thanks!
