Sound distorted of audioinjector-octo soc:soundcard since kernel version 6

[vanmanda]

I've been testing the audioinjector octo sound card with several firmwares.
This card seems to work fine with the latest version 5 kernel (5.15.92). As from the first version 6 kernel till the latest, this soundcard only produces noise. There is nothing recognizable as voice or music when playing audio, only noise.
I see this error with v6:
[ 13.889229] audioinjector-octo soc:sound: ASoC: driver name too long 'audioinjector-octo-soundcard' -> 'audioinjector-o'

You'll find a more detailed log output below. This output comes from kernel 6.1.13, but with 6.6.22 I get a similar result.

Does anyone know how to fix this?

Thanks!
