weird audio issue on virtual sound adaptor

[mcdull]

I set up a VM for live streaming on youtube.
Since no hardware GPU, I uses software h264 encoding which is fine.

On the audio side, if I have a console (SPICE) connected, everything goes very well. However, if this SPICE client is disconnected, audio will goes shutter.
Doubling CPU / RAM make no difference.

So I am now creating another VM, just to run a SPICE client to connect to the VM to maintain the audio quality. Sounds stupid, right?
Any idea on this one?

Thanks.

I'm having a similar issue, once RDP is disconnected the audio device disappears and streaming comes to a halt.

How to achieve software h264 encoding，are there configuration parameters?
