Doug, Philip, and Everyone I started a new thread with the quotes below to make sure to not hijack the thread where they were taken from ... 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 On Thu, 23 Nov 2017 21:49:17 -0500 Doug <dmcgarrett@xxxxxxxxxxxxx> wrote: [ ... ] > Perhaps I should elaborate: On my system, I have a MB with a sound > output.

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.

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 ..
