Re: snd-aoa on PowerMac 8,2
I guess that should relate the "base register" somehow. Maybe something like ONYX_REG_BASE + 0
Then I could set my base register at 0x46 and the rest would work. Maybe.
No, you're confusing registers and i2c addresses :)
Ok, it was a wild guess actually, I don't have a clue. Thanks for the explanation.
So this is the output with the latest code, I'll let you debug it :). I added the port to the printk, just to check if both 0x46 and 0x47 were being tried.
