[alsa-devel] HDMI v. ICH8 on Dell XPS M1330

[Tellman, Steven]

Actually, I've seen this as well, haven't really started to debug it. We
define in the verb table of that system this:

;#21# <STAC9228> (SPDIF Out:Pin48) Jack:Other Digital, Digital, Black,
A:A, S:0, Loc:Internal, Sp.8 (Bay, HDMI), Det:No, Imp:No
;#21#Config=0x185610A0

Notice we use the "Other Digital" as the jack. Is that possibly causing
a problem? IEC958 shows up, but doesn't provide output to HDMI devices
(that I've tested).

The HDMI on HD-audio is currently handled equivalently with SPDIF.
So, this device is the HDMI.  Try to output this?  Don't forget to
adjust 'IEC958'-related mixer controls.

Use alsa-info.sh.  This will contain far more information.

thanks,
