<ogra_> stuw, do you have an ubuntu install by chance ? on all arm installs we have ucm files for the panda, based on these it should be not to hard to create an ucm profile for someone who understands alsa deeply enough

For downstream kernel

"Modern mobile devices are increasingly required to provide a rich set of audio functionality required by todays applications. This richer functionality places additional requirements on the audio hardware and leads to further complexity. Example: a modern Linux phone could have as much as 80 bespoke ALSA audio controls to manage different use cases." --- http://www.slimlogic.co.uk/2009/02/alsa-use-case-manager/

UCM for pulse audio

<ogra_> stuw, do you have an ubuntu install by chance ? on all arm installs we have ucm files for the panda, based on these it should be not to hard to create an ucm profile for someone who understands alsa deeply enough ... <ogra_> well, all ucm needs is a /usr/share/alsa/ucm/<device> directory and the profile files in there that are essentially amixer settings <ogra_> to enable ucm you then run: alsaucm set _verb <profile name>


Current UCM config from ogra: 

# UCM configuration for tegra-alc5632

ValueDefaults {
  PlaybackCTL "hw:0"
  CaptureCTL "hw:0"
}

Save this file as /usr/share/alsa/ucm/tegraalc5632/tegraalc5632.conf NOTE: for modern kernels replace "hw:tegraalc5632" to "hw:PAZ00"

And apply ucm settings: 

alsaucm -c tegraalc5632 reset
