Great news folks. Very loud audio!
The secret was the stuff involving address 0x70000084 and 0x70000080!
Now to work on the algorithms for tuning and getting volume control to
work with the line1 in (very loud even if gain is very low)
Btw, the settings below actually mute line1 in while tuning, so it is a
bit misleading :)
Thanks for the help with figuring this out.

So nothing more to be done with the radio init/powerup.
I bet, that the audio configuration is not correct yet.
In the emu I found following AS3514 init sequence after entering the
radio menu
and after setting up the tuner:
AUDIOSET1 4e
70000084 |= 1 <<<<< don't know, wether this is radio related
70000080 |= 4 <<<<< don't know, wether this is radio related
HPH_OUT_L e0
HPH_OUT_L 6b
HPH_OUT_R eb
LINE_IN1_L df
LINE_IN1_R df
AUDIOSET1 4a
AUDIOSET1 4e
LINE_IN1_L df
LINE_IN1_R df
And regarding your other question:
69ddd55 0000e8f4 CPU ???????? 70000020 R4-40000000
69ddd57 0000e8fc CPU ???????? 70000020 W4-40000000
I added the comment after looking at the assembler code at addr 0000e8f4.
The cpu reads a value from 0x70000020, bics bit11 and stores the
result. Nothing wrong here.
