Right now, the AESS driver is not working. This is a driver that enables hardware support for mixing, converting, etc. audio streams. Without it, the CPU has to do everything, which is a horrible waste of CPU power. Andrej started to work on this, but the current status is unknown: https://github.com/andrey-utkin/linux/tree/pyra-aess

I can work on it as I'm familiar with kernel sound subsystem.

A new version is available which seems to work on OMAP5 but breaks boot process on Pandaboard-ES. It even makes the Pandaboard reboot.

Has become worse with v5.3-rc1 because kernel APIs have changed and some more code had to be disabled.
