• In the case of a12/13 it seems to be a problem of the build that is already solved when building the rootfs from scratch.
• For the PS5000 the issue is a bit more complicated as the volume controls didn't work and after changing the alsa configuration aliases (we need to add rockchip_rk312x cards.rk817 in the file buildroot/board/rockchip/ps5000/fs-overlay/usr/share/alsa/cards/rockchip_rk312x.conf) the headphones stopped working. The fix seems to be to remove the lock true line from the hook args for the playback.pcm entry in the configuration for RK817 driver (see the change in the PR).

Side note: for the a12/13 the alias is not needed and everything worked as it is, so I didn't explore it following a simple approach: if it ain't broke, don't fix it. Nevertheless, it would be a good idea in the future to have a look and understand what is actually happening and find out whether we have part of the driver config that is actually never used.

Reopening as it seems there is a regression here on the PS5000 at least. As the system didn't change at all, it is probably related to the init process of the external rootfs.
