Guest audio pass via vRDP sound weird (jitter?)

[NoNoNo]

HOST is Debian 9.3
GUEST is Windows XP

What sound like: Jitter? echo in the tunnel?
(It may not be noticed if playback duration is less than a second.)

At first I suspect that remmina client cause it. Later I found Microsoft's RDP client (mstsc.exe) also run into this.

Tried to change sound back-end between PulseAudio and ALSA, No avail.

[NoNoNo]

It behave the same under Vbox 5.1.34, and 5.1.36

update: and 5.1.38 got problem, too.

I like to notify dev, that GUEST Linux desktop is normal, just GUEST windows XP I encounter has sound problems.

I confirm the issue. I have it on v5.2.20 too.

Host: Windows Home Server 2011, Guest: Windows XP Pro SP3. Client: Windows 10 RD client.

Can confirm this issue under v5.2.20 with a Mac OS X 10.14 host with as client Ubuntu Server 18.04.
