Hello !
I have a problem with an OrangePi Zero under Armbian Buster with mainline kernel (5.8). I need to put the module snd-aloop as primary soundcard (index=0), and the integrated soundcard sun4i-codec as index=1. It worked very well with kernel 5.4 and before. I just had to load the snd-aloop module by adding it to /etc/modules and add "options snd-aloop index=0" to /etc/modprobe.d/alsa.conf. But now this is impossible, snd-aloop doesn't load. I had this message when I try to load it manually : modprobe: ERROR: could not insert 'snd_aloop': No such device
After reading configuration file of the kernel, I saw that the module sun4i-codec (integrated soundcard) was directly integrated into the kernel, not as an external module, which is confirmed by the lsmod command, it no longer returns the name of the module. I think this is the reason of this issue, because this is the main change between the two versions. I have the impression that the index of the integrated sound card is no longer editable, unless you provide me a solution.
I tried to invert indexes, but my software is too complicated to modify (experimental analog-to-digital gateway for HAM radio communications), so I need to keep the original configuration. I have also tried configuring indexes manually in kernel arguments, with no success.
Can you help me please, because I can't downgrade to 5.4 to ensure the sustainability of the project. Thanks in advance
