So I added reg properties to the cpcap codec end too and now I get the
mapping set right:
asoc-audio-graph-card soundcard: cpcap-hifi <-> 40124000.mcbsp mapping ok
asoc-audio-graph-card soundcard: cpcap-voice <-> 40126000.mcbsp-dai0 mapping ok
asoc-audio-graph-card soundcard: mdm-call <-> 40126000.mcbsp-dai1 mapping ok
Hmm I wonder if this will now need all the dts files updated for codecs
with multiple DAIs?
Also audio play does not work for me with these changes it seems.. My
updated codec end snippet below.
Regards,
Tony
