Hi Tobin,
Thanks for responding. I've added the output of the alsa-info.sh as an
attachment to the issue report page:
https://bugtrack.alsa-project.org/alsa-bug/file_download.php?file_id=2210&type=bug
The model I'm struggling with is an NX100X, the bug was initially opened in
regards to an MX3414 and others have reported the same trouble with an
ML3109. The only reason that I mention this is that they all use the same
ini file and windows driver, can't say with any real certainty if the
hardware is identical, but they are all using stac9200 and agere softmodem
codecs (the one that was reported recently as being claimed by the
patch_si3054 erroneously, so I've removed that id from patch_si3054.c and
also used probe_mask=1). I'm currently using an hg build from about two
days ago.
As for the pin configs, I've read the datasheet front to back several times
and as near as I can tell they are correct. What is shipped with the
gateway driver seems like a very generic set of values - very similar to
what the codec datasheet specifies as the defaults. These values are also
what the windows registry reports, but those reported by microsoft's
"uaatest" utility (from the MS hardware compatibility testsuite) seem to
make a lot more sense, and since they are from a direct probe of the codec
I've stuck with these. I've tried every variant that makes sense to me, but
so far the only port that produces sound is the mic.
I also removed the motherboard from the laptop and probed around a bit with
a continuity meter. The only notable thing that I could get from this was
that I did not have continuity from any of the pins in the speaker connector
to any of the pins on the codec - so I assume that there is an external amp
somewhere, though I couldn't locate it. Is it possible that the modem is
somehow involved? I've tried setting the EAPD bit but nothing there
either... (however GPIO3 doubles as the SPDIF in and also controls EAPD, and
the windows driver does have a "GPIO: "3": hex:85" line - I emailed IDT and
asked what the significance of this was but never got a response).
Thanks,
-brian
