[sweep-users] just installed sweep on debian 9, cannot hear sound through my hdmi, only through direct computer port

[Dan H. <dan...@gm...>]

sweep exists as a package in the debian 9 system ("stretch").

So i installed version 0.9.3 to try it out.

It seems to correctly display sound files, and looks like it has a
bunch of useful features, but it does not play through my hdmi.

Other sound playing software (such as audacity and mpv) do play
through hdmi, so i think my audio is functional.

For the audio configuration, from Playback > Configure Audio Device,
there are four options:
    plughw:0,0
    plughw:0,1
    plughw:1,0
    plughw:1,1

Of these, 0,0 plays through the direct computer port.  01, and 1,1
give errors if i try to play.  1,0 acts as though it is playing, but i
don't hear anything.

I would like to play all my audio through the hdmi (because sometimes
i attach a different computer to it so it is more convenient that
way).

Thanks in advance for any clues!
