Subject: [alsa-devel] [PATCH RFC v3 0/8] Beaglebone-Black HDMI audio

Hi,

I think you should try to get this in sync with the work Jean-Francois is
currently doing[1]. Having the HDMI transmitter register a CODEC device is
definitely the right approach, compared to the rather 'interesting'
constraints stuff you do in patch 4.
