That would appear to be the case. According to the VT1708S datasheet,
the typical application is for digital output widget node 0x12,
attached to pin complex node 0x20, to be used for S/PDIF, and digital
output widget node 0x15, attached to pin complex node 0x21, to be used
for HDMI. The datasheet’s default values for the Configuration Default
words for the two pin complex nodes agree with that configuration. This
also appears to be how my motherboard is configured.
However, I have attached /proc/asound/card0/codec#0; this file states
that node 0x20 is HDMI and 0x21 is S/PDIF, and having decoded the raw
words based on the Intel HDA specification revision 1.0a, I agree that
the kernel is decoding them correctly. I assume the kernel driver
doesn’t change these words, which means the information I’m seeing
there, since it’s not the codec default, must have been put there by
the BIOS, apparently erroneously.
Is this something that the ALSA project wants to (or even can) add a
quirk for? I am already running the most recent BIOS available.
