Linux client as the host Version 5.0.418682.0603 amd64
Windows 10 as the guest
As Host:
(1) mute microphone
(2) set own speaker volume to a normal level
(3) go to Share Screen, Advanced, Computer sound only
(4) select an mp3 on your desktop and play via Rhytmbox, Audacity or Video Player

The sound on the Guest machine is badly distorted – like a Dalek on helium. (I was going to attach an audio file as automatically saved by Zoom to the host machine but apparently it isn't a supported attachment file type in this forum.)
If Host forgets to mute the microphone in step 1 the Guest sometimes hears a very loud high-pitched whine which cannot be muted at the Guest end, presumably a feedback loop between the Host microphone and the computer audio.

Windows 10 as the host
Linux client as the guest Version 5.0.418682.0603 amd64

As Host:
(1) mute microphone
(2) set own speaker volume to a normal level
(3) go to Share Screen, Advanced, Computer sound only
(4) select an mp3 on your desktop and play via Groove Music, VLC or Windows Media Player

The sound on the Guest machine is OK.
If the Host forgets to mute the microphone in Step 1 the Host hears an echo but the Guest machine sound is apparently unaffected.

With both scenarios, it is important that the Host sets a normal playback level on their media player because if the sound level is too low the Guest will hear nothing.
