PulseAudio runs if using alsa-lib 1.0.26, but crashes on alsa-lib
1.0.25. I also didn't see HDMI listed in sound settings or sinks for
pulse using alsa-lib 1.0.26 on pandaboard either. Not sure whats going
on, I'll dig deeper tomorrow.
The UCM configuration might not have entries for HDMI. If so, then HDMI
won't be available if PulseAudio successfully loads the UCM
configuration.
If you don't need UCM, you can disable it and use PulseAudio's "normal"
configuration instead, which should make HDMI work (if it worked with an
older version PulseAudio).
Sorry, I lied. You can't disable UCM, at least if you're relying on
module-udev-detect. I'll make a patch that fixes this.
I built pulseaudio with your patch included, and whilst it allows pulse 3 to
work with alsa 1.0.25 by disabling UCM, HDMI is still not shown, even with
alsa-lib 1.0.26. Log attached.
From looking at the log, it looks like the HDMI sink is in fact what
shows up, even though the port of that sink is "Analog Output".
The headphone/line out fails to open at the lines below. From a quick
look at the code I didn't see anything obviously related between 2.1 and
3.0, so could you please verify with 2.1 that things are working better
there (i e both sinks show up)?
