Short version: The whole thing isn't that important - if in doubt, ignore it ... :) The main reason I wrote this email is plain and simple curiosity about whether it can be done, and how: namely to feed sound on a Linux machine to two audio systems at the same time: to internal speakers on the computer and to external ones like, e.g., those in a TV, via HDMI. And all this on Fedora 26 system

Perhaps I should elaborate: On my system, I have a MB with a sound output. I also have an NVidia video card that also contains a sound decoder with an HDMI output jack. With this combination, AND PulseAudio, I can get simultaneous sound (near the computer with the MOBO sound output) and video on both the local monitor and the TV from the NVidio card, AND sound on the TV from the NVidia card also, via the hdmi connection. It may take some serious fiddling around with the possibilities in PA, but it CAN be done.
To get sound simultaneously from your internal computer speakers and TV (connected via HDMI): which tool(s) did you use? pavucontrol? paman? paprefs?
Settings in ~/.asoundrc ?
Looks like I have two sound systems on my machine - if true it might be possible to run them concurrently: _______________________________ lspci -nnk |grep -A 7 -i vga 00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) Subsystem: Dell Device [1028:05aa] Kernel driver in use: i915 Kernel modules: i915 00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06) Subsystem: Dell Device [1028:05aa] Kernel driver in use: snd_hda_intel Kernel modules: snd_hda_intel -- 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

Specs regarding the lspci result from above: Please note that on this machine there's one mini display port and one HDMI port:
AMD specs for the Radeon card say the DisplayPort 1.2 (mini display port is broken on current Fedora¹ since quite some time) is "Multi-Stream", while the specs on HDMI (works here) say nothing about "Multi-Stream" http://www.amd.com/en-us/products/graphics/desktop/oem/8900#
That's what Intel says about E3-1200 v4 on https://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200v4-vol-1... -------------------------------- "The processor also integrates dedicated a Mini HD audio controller to drive audio on integrated digital display interfaces, such as HDMI* and DisplayPort*. The HD audio controller on the PCH would continue to support down CODECs, and so on. The processor Mini HD audio controller supports two High-Definition Audio streams simultaneously on any of the three digital ports." ------------------------------ The last sentence: "The processor Mini HD audio controller supports two High-Definition Audio streams simultaneously on any of the three digital ports."
Philip: After I wrote, that I cannot use both speaker systems (internals speakers from the computer and external ones from e.g. TV) at the same time you mentioned ~/.asoundrc:
"That should be fixable with a properly configured .asoundrc file? - might need an ALSA guru to do it though . ."
Might be difficult to find ALSA gurus ... :) - but I played with .asoundrc years ago on a Macintosh powerp machine, with Debian on it - with surprising results (and I'm far from being an audio guru): https://lists.debian.org/debian-powerpc/2009/08/msg00049.html
So thanks for pointing to .asoundrc: it hinted to me that ALSA is still there - didn't realize that - I simply thought it was gone with pulseaudio. And yes: I had not much of an idea of what PA actually is until yesterday - I just knew that audio worked here ...
Sound setup tho' *might* become more complicated now with both pulseaudio plus alsa being involved - not sure about it yet ..
Thanks again .. Wolfgang

As I said, there is sound on the mother board. That comes out of the mobo on a "headphone" jack and goes to a Logitech system that has a box with an 8" speaker (for bass) and two small speakers for the rest, and an audio amplifier that is in the big speaker box. The HDMI output comes out of the NVidia card on a miniature hdmi connector (You need an adapter, or a special cable) and goes to the TV carrying video and audio, IF YOU HAVE PA CONFIGURED RIGHT. It will always give video, but audio depends on how well you finagle PA's many possible configurations, which is the harrowing experience. It will help if you can hear the TV sound while you're messing with this. (Turn down the local sound and listen for the TV sound. Run something like YOuTube with a long output, like a DVD repro, or something.)

Try the google search "pulseaudio multiple outputs".
Seems to be plenty of information available.

Well, obviously: you're right. Shame on me, and thanks for helping some at-least-at-times-blind guy cross the road ... ;)

I found this writeup extremely helpful. It doesn't touch alsa at all but uses other higher level tools to accomplish what you're looking for, specifically: pavucontrol (pulseaudio volume control) and paprefs (pulseaudio preferences).

That page looks useful, tho' my hardware seems different: the basics seem to be the same: like on the page above I have the 3.5 mm jack available (IINM for the Intel Xeon audio system) plus the Radeon (?) HDMI audio via one HDMI connector on the machine.
These pages might be fine, too: https://askubuntu.com/questions/78174/play-sound-through-two-or-more-outputs... https://unix.stackexchange.com/questions/143865/how-to-enable-both-built-in-...
It looks like one really needs some understanding about audio soft- and hardware setups to make sure that if wrappers like pulseaudio or pipewire¹, the new one on F27 that might replace at least parts of PA, break setups we're still able to fix them ... still learning .. :)
For a starter if one wants a quick idea of how extensive the whole audio setup can become one might try a look into the files in /usr/share/pulseaudio/alsa-mixer/paths/ ... :)
Thanks Mike, and to Doug, too, who already replied before.
