[pulseaudio-discuss] Accessing audio as root

Presumably an HDMI device.

Strange that this is not possible anymore. You should be able to set an
"Off" profile in pavucontrol's Configuration tab to have pulseaudio
ignore any given card and use it for what you like.

I presume this is an Intel HDA card. I have a similar card here and it
works very well with pulse but the HDA range is really more of a
specification than a particular device and there are numerous small
variations and a whole bunch of quirks in ALSA to deal with it. Strange
that it only has a few squeaks tho'. Is this with Glitch Free mode
disabled in draksound?

Yeah creative cards can be problematic due to their lack of support for
the more advanced way PA drives the hardware.

OK, let me clarify:

pacmd ls output *while pulseaudio is running* would be good.

It should detect the Audigy 2 card even if it doesn't work fantastically
in glitch free mode. HDMI cards should be prioritised below PCI cards in
the internal priority list so it should never be the default if other
cards are detected. The pacmd ls output should be telling.

Also, if you can post the pulseaudio -vvvv output too that would be
useful. Can you start a new thread for this?
