I'm struggling to get sound working with a main line kernel linux-18.104.22.168
At boot I'm getting...
dw_dmac.0: DesignWare DMA Controller, 3 channels
Advanced Linux Sound Architecture Driver Version 1.0.20.
AC'97 0 does not respond - RESET
AC'97 0 access is not valid [0xffffffff], removing mixer.
atmel_ac97c: probe of atmel_ac97c.0 failed with error -5
ALSA device list:
No soundcards found.
Is this failure to reset the problem, or is that a red-herring?
The H/W is based on the old STK1002 board.
