The alsa/acp code already supports getting a user-friendly monitor name
using the EDID-Like Data (ELD) information available from cards that follow
the Intel HDA specification.
This patch adds support for also parsing the SAD fields of the ELD, and
exposing the results as a "iec958.codecs.detected" property on the
corresponding node, which should make it possible to provide more
user-friendly configuration UIs and defaults.
The default value will take effect if the session manager does not set a
different value.
Brief example:
test@test:~/checkouts/pipewire$ pw-dump | grep -E "(iec958.codecs.detected|iec958.codecs)\":"
"iec958.codecs": "[\"PCM\",\"AC3\",\"EAC3\",\"TrueHD\"]",
"iec958.codecs.detected": "[\"PCM\",\"AC3\",\"EAC3\",\"TrueHD\"]",
<after powering on my receiver>
test@test:~/checkouts/pipewire$ pw-dump | grep -E "(iec958.codecs.detected|iec958.codecs)\":"
"iec958.codecs": "[\"PCM\",\"DTS\",\"AC3\",\"EAC3\",\"TrueHD\",\"DTS-HD\"]",
"iec958.codecs.detected": "[\"PCM\",\"DTS\",\"AC3\",\"EAC3\",\"TrueHD\",\"DTS-HD\"]",
Big thanks to Pauli Virtanen <pav@iki.fi>, who also wrote large paths of the
code for this patch.
