[alsa-devel] Request for help CM109 on arm board

[Jonathan Andrews]

Its bad form, but here is a follow up to my own thread in the hope
somebody will guide my through this maze ?

NOTE: For ALSA 1.0.9rc2 and higher you don't need to setup dmix for
analogue output. Dmix is enabled by default for soundcards which don't
support hardware mixing. You still need to set it up for digital
outputs.

Yea .....  right .....
