Hi Krzysztof,
I know I already reported this on IRC, I thought I'd duplicate the info
here for completeness sake.
Due to how the sound node is parsed the device numbers in alsa are
derived from the index of the sound/mmX-dai-link child nodes.
For boards which use more than 3 FE's this causes breaking changes in
userspace, as the slim-dai-link and slimcap-dai-link nodes now come
before the other mmX-dai-link nodes, for example with my OnePlus 6
patches "aplay -l" shows:
card 0: O6 [OnePlus 6], device 0: MultiMedia1 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: O6 [OnePlus 6], device 1: MultiMedia2 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: O6 [OnePlus 6], device 2: MultiMedia3 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: O6 [OnePlus 6], device 5: MultiMedia4 (*) [] <-- 5 instead of 3
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: O6 [OnePlus 6], device 6: MultiMedia5 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: O6 [OnePlus 6], device 7: MultiMedia6 (*) []
Subdevices: 1/1
Subdevice #0: subdevice #0
This breaks the UCM configs shipped by postmarketOS and Mobian - though
none of it is "upstream".
Would it be reasonable to add all 6 FE DAI's and then disable the unused
ones on a per-board basis?
