Does the select from SND_SOC_AC97_BUS actually happen if it is selected by SND_SOC_ALL_CODECS? That's the issue, if it works now it's a relatively recent thing.
I'm not sure I fully understand what you mean.
The Kconfig entry for the CODEC has no 'depends on'. It does a 'select SND_SOC_AC97_BUS', which means all built time dependencies are pulled in this way. So if SND_SOC_ALL_CODECS selects the CODEC unconditionally that should work fine, since no dependencies are bypassed.
No, it's not just dependencies but also selects that get ignored (or used to anyway like I say) - a select just forces the symbol on.
select forces a symbol on regardless of whether its dependencies are met or not. But for any symbol that is on, no matter whether it was manually selected or selected by a 'select' from another symbol, any symbols selected by that symbol will be turned on. It's been that way as long as I can remember.
