How to direct audio output

[Victor Odhner]

Michael, thanks for boosting my trust in Mint.

Yes, pavucontrol is available via the regular sources and works perfectly, just as smooth as on the Mac. I only wondered why they don’t install it by default, but I guess for some it would just be clutter.

I got my sound running — I’m not sure what I did, but I think both my output devices had disable buttons which I guess must have been in effect; I hit a few buttons so I’m not sure what did it. Again, I don’t know what I had done that shut it down in the first place.

I thought I would concoct a panel launcher for pavucontrol, so I did this:
  Add to Panel > Launch
… and this led me to a menu of apps I hadn’t seen before; and one of them was pavucontrol.
Can’t beat that!

Thanks again.

Mint's audio panel might not let you do it, but install pavucontrol, which is pulseaudio volume control, which can (I always install and use this only).  

When you play the video with whatever generating audio, pavucontrol should show in "playback" menu, with the destination audio as hdmi output card.  Change that to be your other audio destination, the usb dac, and that should be all you need to divert audio there.  If you don't see another device, ensure all are enabled in Configuration and you see them both under Output Devices.

Check and make sure all the playback applications are seeing audio levels, and then make sure the appropriate output device is as well under output does too as they can work independently.

Everything I find online seems to indicate that nobody’s created a similar configuration tool for Linux, that we have to use some queries and build a config file. The query I tried did show that there are two devices, but I really don’t know what I’m doing.

Any instruction would be greatly appreciated.

My situation:

In my Mint system, I want to drive a monitor via HDMI,
and sound via USB > Digital-to-Analog converter > mixer board.
The very same connection worked when driven by the Mac Mini.
Linux never had a problem with it either, but I messed up something.

At one point the sound was playing through the monitor’s relatively weak loudspeaker.

After some tinkering, nothing is coming through.

Thanks,
Victor
