SPDIF out with HDA/Conexant 20561?

SPDIF out with HDA/Conexant 20561?

[pl bossart]

Has anyone had any luck enabling S/PDIF output with the Conexant 20561/ctx5051?

On my Lenovo W500 I see a digital output device, I can play on it but
I can't hear any sound on my receiver. There was a patch by Takashi
earlier this year to correct a wrong nodeID
(03b515c45e2a93331d2ac9dc1c16440f7fa313ec, ALSA: hda - Fix SPDIF
output widget for Cxt5051 codec), so I figure some amount of testing
has been done already?

I wonder if this comes from a non-initialized pin configuration as
reported in /proc/asound/card0/codec#0?

Are you using the Thinkpad Docking station with the S/PDIF on the side?
The headphone jack on those doesn't have S/PDIF.

I have not been able to verify this so glad your email came.. but it
seems like the T400, T500, & W500 do not actually work with it.

Did you try under Windows & if so did it work?

				Thanks,

Yes I am using the side coax connector on the docking station.

No I don't have Windows on this thing. For now I have no real way to
tell if the output is properly configured, if the connector works, if
the cable's bad...

I know the T61 is properly wired for it. Had a chance to try it in
person. It also had a AD codec as opposed to conexant.

This has been the main issue. Can't get a total confirmation that it
even works to begin with for these machines. Also Lenovo has removed the
port from the recent line of docking stations. 

If I can find anything useful .. I'll reply back soon.

I really wanted to remove the SPDIF port being exposed as it shows up on
my X301 .. and X200 (They all have the same codec), but don't use that
docking station. But the use case your trying to do is the only way to
do it and it would only be with the T400/T500 & W500 .. though no where
can I find someone clearly saying they got it to work (even with
Windows).

I managed to have playback working for both PCM and AC3 in passthrough
mode, found out there is a configuration issue in the HDAudio codec.
By default the SPDIF pin isn't enabled, configuring it as PIN_OUT is
required. Also for some reason there's a switch that selects a quirk
for no good reason. I need to look into this, but here's the fix for
now.
The question is if SPDIF pin is never configured as out, did it ever
work for anyone using Conexant codecs?
Cheers
