Hi @doitright ,
Currently I am trying to upgrade the HiKey960 board with android 11 version and kernel v4.19. After upgradation, everything seems to be fine except sound card capture (pcmC0D0c) is missing. It only listed pcmC0D0p.
hikey960:/ # cat /proc/asound/cards
0 [hikeyhdmi ]: hikey-hdmi - hikey-hdmi
Under /dev/snd/, I have the following devices,
controlC0 pcmC0D0p timer
Now, my question is how to add sound card capture device pcmC0D0c? Where we have to made changes in kernel code to configure this?
Note : In android 11 and kernel v4.9, both sound cards pcmC0D0c and pcmC0D0p are listed properly. Only in kernel v4.19, sound card capture is missing.
Thanks in advance,
